5b311c1519 mmc: sdhci-cadence: add Socionext UniPhier specific compatible string
Add a Socionext SoC specific compatible (suggested by Rob Herring).

No SoC specific data are associated with the compatible strings for
now, but other SoC vendors may use this IP and want to differentiate
IP variants in the future.

786a72d791 ARM: DT updates for v4.10
Lots of changes as usual, so I'm trying to be brief here. Most of the
 new hardware support has the respective driver changes merged through
 other trees or has had it available for a while, so this is where things
 come together.
 
 We get a DT descriptions for a couple of new SoCs, all of them variants
 of other chips we already support, and usually coming with a new
 evaluation board:
 
 - Oxford semiconductor (now Broadcom) OX820 SoC for NAS devices
 - Qualcomm MDM9615 LTE baseband
 - NXP imx6ull, the latest and smallest i.MX6 application processor variant
 - Renesas RZ/G (r8a7743 and r8a7745) application processors
 - Rockchip PX3, a variant of the rk3188 chip used in Android tablets
 - Rockchip rk1108 single-core application processor
 - ST stm32f746 Cortex-M7 based microcontroller
 - TI DRA71x automotive processors
 
 These are commercially available consumer platforms we now support:
 - Motorola Droid 4 (xt894) mobile phone
 - Rikomagic MK808 Android TV stick based on Rockchips rx3066
 - Cloud Engines PogoPlug v3 based on OX820
 - Various Broadcom based wireless devices:
   - Netgear R8500 router
   - Tenda AC9 router
   - TP-LINK Archer C9 V1
   - Luxul XAP-1510 Access point
 - Turris Omnia open hardware router based on Armada 385
 
 And a couple of new boards targeted at developers, makers
 or industrial integration:
 - Macnica Sodia development platform for Altera socfpga (Cyclone V)
 - MicroZed board based on Xilinx Zynq FPGA platforms
 - TOPEET itop/elite based on exynos4412
 - WP8548 MangOH Open Hardware platform for IOT, based on
   Qualcomm MDM9615
 - NextThing CHIP Pro gadget
 - NanoPi M1 development board
 - AM571x-IDK industrial board based on TI AM5718
 - i.MX6SX UDOO Neo
 - Boundary Devices Nitrogen6_SOM2 (i.MX6)
 - Engicam i.CoreM6
 - Grinn i.MX6UL liteSOM/liteBoard
 - Toradex Colibri iMX6 module
 
 Other changes:
 - added peripherals on renesas, davinci, stm32f429, uniphier, sti,
   mediatek, integrator, at91, imx, vybrid, ls1021a, omap, qualcomm,
   mvebu, allwinner, broadcom, exynos, zynq
 
 - Continued fixes for W=1 dtc warnings
 
 - The old STiH415/416 SoC support gets removed, these never made it into
   products and have served their purpose in the kernel as a template
   for teh newer chips from ST
 
 - The exynos4415 dtsi file is removed as nothing uses it.
 
 - Intel PXA25x can now be booted using devicetree
 
 Conflicts:

 dropping the required '};' at the end of each side.

The "clock-freq-min-max" property was deprecated.
There is "max-frequency" property in drivers/mmc/core/host.c
"max-frequency" can be replaced with "clock-freq-min-max".
Minimum clock value might be set to 100K by default.
Then MMC core should try to find the correct value from 400K to 100K.
So it just needs to set Maximum clock value.

4cbc6dbd52 dt: bindings: Make compatible optional for mmc function nodes
On some boards (android tablets) different batches use different sdio
wifi modules. This is not a problem since mmc/sdio is an enumerable bus,
so we only need to describe and activate the mmc controller in dt and
then the kernel will automatically load the right driver.

Sometimes it is useful to specify certain ethernet properties for these
"unknown" sdio devices, specifically we want the boot-loader to be able
to set "local-mac-address" as some of these sdio wifi modules come without
an eeprom / without a factory programmed mac address.

Since the exact device is unknown (differs per batch) we cannot use
a wifi-chip specific compatible, thus sometimes it is desirable to have a
mmc function node, without having to make up an otherwise unused compatible
for the node, so make the compatible property optional.

b465646ef4 mmc: sunxi: sun4i / sun5i do not have sample clocks
It turns out that sun4i (A10) and sun5i (A13 & co) do not have sample
clocks, so add a new sun7i-a20-mmc compatible and do not try to use
sample clocks on sun4i / sun5i.

Since sun4i / sun5i do not have sample clocks, they cannot (reliably) do
DDR rates, so only set MMC_CAP_1_8V_DDR when we do have sample clks.

Note this patch leaves the clk_prepare_enable() / clk_disable_unprepare()
calls to the sample clks as-is, without adding checks for them being
NULL. All the clk_foo calls accept a NULL clk and will return success when
called with a NULL clk.

6db90c5976 Documentation: mmc: sdhci-of-arasan: Add ability to export card clock
Some SD/eMMC PHYs (like the PHY from Arasan that is designed to work
with arasan,sdhci-5.1) need to know the card clock frequency in order to
function properly.  Physically in a SoC this clock is exported from the
SDHCI IP block to the PHY IP block and the PHY needs to know the speed.
Let's export the SDHCI card clock using a standard device tree mechanism
so that the PHY can get access to it and query the card clock frequency.

6582019927 Documentation: mmc: sdhci-of-arasan: Add soc-ctl-syscon for corecfg regs
As can be seen in Arasan's datasheet [1] there are several "corecfg"
settings in their SDHCI IP Block that are supposed to be controlled by
software.  Although the datasheet referenced is a bit vague about how to
access corecfg, in Figure 5 you can see that for Arasan's PHY (a
separate component than their SDHCI component) they describe the
"phyctrl" registers as being "FROM SOC CTL REG", implying that it's up
to the licensee of the Arasan IP block to implement these registers.  It
seems sane to assume that the "corecfg" registers in their SDHCI IP
block works in a similar way for all licensees of the IP Block.

Device tree has a model that allows a device to get a reference to
random registers located elsewhere in the SoC: sysctl.  Let's leverage
this model and allow adding a sysctl reference to access the control
registers for the Arasan SDHCI PHYs.

Having a reference to the control registers doesn't do much for us on
its own since the Arasan spec doesn't specify how these corecfg values
are laid out in memory.  In the SDHCI driver we'll need a map detailing
where each corecfg can be found in each implementation.  This map can be
found using the primary compatible string of the SDHCI device.  In that
spirit, document that existing rk3399 device trees already have a
specific compatible string, though up to now they've always been relying
on the driver supporting the generic.

Note that since existing devices seem to work fairly well as-is, we'll
list the syscon reference as "optional", but it's likely that we'll run
into much fewer problems if we can actually set the proper values in the
syscon, so it is strongly suggested that any SoCs where we have a map to
set the corecfg also include a reference to the syscon.

2ec3240fd7 ARM: 64-bit DT updates for v4.7
We continue ramping up platform support for 64-bit ARM machines,
 with 111 individual non-merge changesets touching 21 platforms.
 
 The LG1312 platform is completely new and is the first ARM
 platform by LG that we support in the mainline kernel. Two other
 SoCs got added that are updated versions of existing SoC
 families, so the port mainly consists of new dts files:
 - The Hisilicon Hip06/D03 is the latest server platform
   from Huawei/Hisilicon, and follows the Hip05/D02 platform.
 - Rockchip RK3399 follows the 32-bit RK3288 that is popular
   in low-end Chromebooks and the 64-bit RK3368 that is mainly
   found in chinese Android TV boxes.
 
 The 96Boards HiKey based on the Hisilicon Hi6220 (Kirin 620)
 gets a long-awaited overhaul with a lot of devices enabled in
 the DT, so it should be much more usable with a mainline kernel
 now. See also
 https://plus.google.com/111524780435806926688/posts/PeGb2VsNhJd
 
 A lot of work went into enabling new device drivers on existing
 machines, but we also have a couple of new commercially
 available machines:
 
 - Google Pixel C laptop based on Tegra210
 - Hardkernel Odroid C2 Based on Amlogic Meson GXBB (S905)
 - Geekbuying GeekBox based on Rockchip RK3368
 
 And finally, a couple of reference or development platforms
 that are not end-user platforms but are used for trying out
 the respective SoC platforms:
 
 - Amlogic Meson GXBB P200 and P201 development systems
 - NXP Layerscape 1043A QDS development board
 - Hisilicon Hip06 D03 server board, as mentioned above
 - LG1312 Reference Design

- Fix ABI regression of MMC BLK ioctl
  - Remove the unused MMC_DATA_STREAM flag
  - Enable asynchronous system PM for the host device
  - Minor fixes and clean-ups
 
 SDHCI host:
 Throughout the years, the numbers of SDHCI variants have increased and so
 has also the numbers of SDHCI callbacks/quirks. The purpose of these
 callbacks/quirks were to enable SDHCI to deal with variant specific
 requirements, but unfortunate this method didn't scale. Instead we have
 ended up with a mess. Not only did the code become suboptimal but also
 highly fragile.
 
 Lately many discussions of how to move forward with SDHCI has taken place
 at the MMC mailing list. Step by step, we aim to turn SDHCI's common code
 into a set of library functions. This will enable for optimizations and
 allow some of the existing callbacks/quirks to be removed, which also
 should help to make the code less fragile.
 
 Therefore I am also really pleased to announce that Adrian Hunter (Intel)
 has volunteered to step in as the maintainer for SDHCI.
 
 Future wise, I hope the community around SDHCI will continue to grow and
 that this release cycle can be the starting point of moving SDHCI into a
 better shape. As a matter of fact, already in this cycle the re-factoring
 has begun, but of course there are also fixes and new features included.
 Some highlights:
 
  - sdhci-iproc: Add support for Broadcom's BCM2835 eMMC IP
  - sdhci-acpi: Add support for QCOM controllers
  - sdhci-pic32: Add new SDHCI variant for PIC32MZDA
 
 Other hosts:
  - atmel-mci: Fix a NULL pointer dereference
  - mediatek: Add SD write-protect support
  - mmc_spi: Fix card detect in GPIO case
  - tmio/sdhi: Add r8a7795 support
  - tmio/sdhi: Some fixes and clean-ups
  - dw_mmc: Add HW reset support
  - dw_mmc: Some fixes and clean-ups
  - sunxi: Add support for MMC DDR52 mode

Merge tag 'mmc-v4.6' of git://git.linaro.org/people/ulf.hansson/mmc

Pull MMC updates from Ulf Hansson:
 "MMC core:
      - Fix ABI regression of MMC BLK ioctl
      - Remove the unused MMC_DATA_STREAM flag
      - Enable asynchronous system PM for the host device
      - Minor fixes and clean-ups

  SDHCI host:
     Throughout the years, the numbers of SDHCI variants have increased
     and so has also the numbers of SDHCI callbacks/quirks.  The purpose
     of these callbacks/quirks were to enable SDHCI to deal with variant
     specific requirements, but unfortunate this method didn't scale.
     Instead we have ended up with a mess.  Not only did the code become
     suboptimal but also highly fragile.

     Lately many discussions of how to move forward with SDHCI has taken
     place at the MMC mailing list.  Step by step, we aim to turn
     SDHCI's common code into a set of library functions.  This will
     enable for optimizations and allow some of the existing callbacks
     and quirks to be removed, which also should help to make the code
     less fragile.

     Therefore I am also really pleased to announce that Adrian Hunter
     (Intel) has volunteered to step in as the maintainer for SDHCI.

     Future wise, I hope the community around SDHCI will continue to
     grow and that this release cycle can be the starting point of
     moving SDHCI into a better shape.  As a matter of fact, already in
     this cycle the re-factoring has begun, but of course there are also
     fixes and new features included.  Some highlights:

      - sdhci-iproc: Add support for Broadcom's BCM2835 eMMC IP
      - sdhci-acpi: Add support for QCOM controllers
      - sdhci-pic32: Add new SDHCI variant for PIC32MZDA

  Other hosts:
      - atmel-mci: Fix a NULL pointer dereference
      - mediatek: Add SD write-protect support
      - mmc_spi: Fix card detect in GPIO case
      - tmio/sdhi: Add r8a7795 support
      - tmio/sdhi: Some fixes and clean-ups
      - dw_mmc: Add HW reset support
      - dw_mmc: Some fixes and clean-ups
      - sunxi: Add support for MMC DDR52 mode"

a72e8b1700 mmc: sdhi: Add r8a7795 support
Registers are 64bit apart, so we refactor bus_shift handling a little and set
it based on the DT compatible. Also, EXT_ACC is different. It has been tested
on a Salvator-X (Gen3) and, to check for regressions, on a Lager (Gen2).

9bbd4b9f38 DeviceTree updates for 4.4:
- DT binding doc consolidation moving similar bindings to common
   locations. The majority of these are display related which were
   scattered in video/, fb/, drm/, gpu/, and panel/ directories.
 - Add new config option, CONFIG_OF_ALL_DTBS, to enable building all dtbs
   in the tree for most arches with dts files (except powerpc for now).
 - OF_IRQ=n fixes for user enabled CONFIG_OF.
 - of_node_put ref counting fixes from Julia Lawall.
 - Common DT binding for wakeup-source and deprecation of all similar
   bindings.
 - DT binding for PXA LCD controller.
 - Allow ignoring failed PCI resource translations in order to ignore
   64-bit addresses on non-LPAE 32-bit kernels.
 - Support setting the NUMA node from DT instead of only from parent
   device.
 - Couple of earlycon DT parsing fixes for address and options.
