27a8133136 ARM: dts: OMAP5: uevm: add µSD card detect
If we have Linux installed in eMMC we can boot without
µSD card, but inserting one is not recognised.

The reason is that the card detect gpio (gpio5_152)
is not configured and attached to the mmc1 interface
driver and the mmc driver does not poll by default.

Hence we add pinmux and gpio setup for the SDCARD_NCD
signal.

66579e29f7 ARM: dts: omap5: replace gpio-key,wakeup with wakeup-source property
Though the keyboard driver for GPIO buttons(gpio-keys) will continue to
check for/support the legacy "gpio-key,wakeup" boolean property to
enable gpio buttons as wakeup source, "wakeup-source" is the new
standard binding.

This patch replaces the legacy "gpio-key,wakeup" with the unified
"wakeup-source" property in order to avoid any further copy-paste
duplication.

08f9268b2a ARM: dts: ARM: dts: Fix omap5 SDIO dat1 interrupt
Few changes to fix issues I've noticed while debugging omap5-uevm
wl18xx issues:

1. Move wlcore irq pin muxing under wlcore. This irq could be
   different from gpio_wk14 on some board variants

2. Don't configure pull on wlcore irq pin. There is a 10k
   pull up resistor R105 on the device to VDDS_1v8_MAIN

3. The padconf register for wlsdio_data1 is wrong, it's really
   at 0x1a8 + 2 - 0x40 = 0x16a offset, not at 0x168 as that's
   for wlsdio_data0

4. Mark the omap5-uevm wlan as compatible with ti,wl1837 as
   that's what the TDK R078 part seems to be

5. The MMC interrupt for WLAN musb be wakeupgen, not gic

Looks like omap5-uevm WLAN behaves better now, but I still seem
to have issues with some access points.

ee9a97dbee ARM: dts: Move most of omap5-uevm.dts to omap5-board-common.dtsi
Looks like thevarious omap5-uevm models and igepv5 are very similar. So let's
create omap5-board-common.dtsi to allow fixing up things properly for mainline
kernel to support all these.

Even if we eventually end up having only PMIC + MMC + eMMC + SDIO WLAN + SATA +
USB + HDMI configuration in the omap5-board-common.dtsi, this is the easiest
way to add support for other boards rather than diffing various versions of
out of tree dts files.

My guess is that also omap5-sbc-t54.dts can use this, but I don't have that
board so that will need to be dealt with later on.

0efc898a9b ARM: dts: Fix WLAN regression on omap5-uevm
Commit 99f84cae43 ("ARM: dts: add wl12xx/wl18xx bindings") added
device tree bindings for the TI WLAN SDIO on many omap variants.

I recall wondering how come omap5-uevm did not have the WLAN
added and this issue has been bugging me for a while now, and
I finally tracked it down to a bad pinmux regression, and a missing
deferred probe handling for the 32k clock from palmas that's
requested by twl6040.

Basically 392adaf796 ("ARM: dts: omap5-evm: Add mcspi data")
added pin muxing for mcspi4 that conflicts with the onboard
WLAN. While some omap5-uevm don't have WLAN populated, the
pins are not reused for other devices. And as the SDIO bus
should be probed, let's try to enable WLAN by default.

Let's fix the regression and add the WLAN configuration as
done for the other boards in 99f84cae43 ("ARM: dts: add
wl12xx/wl18xx bindings"). And let's use the new MMC pwrseq for
the 32k clock as suggested by Javier Martinez Canillas
<javier@dowhile0.org>.

Note that without a related deferred probe fix for twl6040,
the 32k clock is not initialized if palmas-clk is a module
and twl6040 is built-in.

Let's also use the generic "non-removable" instead of the
legacy "ti,non-removable" property while at it.

And finally, note that omap5 seems to require WAKEUP_EN for
the WLAN GPIO interrupt.

7136d457f3 ARM: omap: convert wakeupgen to stacked domains
OMAP4/5 has been (ab)using the gic_arch_extn to provide
wakeup from suspend, and it makes a lot of sense to convert
this code to use stacked domains instead.

This patch does just this, updating the DT files to actually
reflect what the HW provides.

BIG FAT WARNING: because the DTs were so far lying by not
exposing the WUGEN HW block, kernels with this patch applied
won't have any suspend-resume facility when booted with old DTs,
and old kernels with updated DTs won't even boot.

bd3c5544a1 ARM: dts: omap5-uevm: update optional/unused regulator configurations
commit e00c27ef3b
(ARM: dts: OMAP5: Add Palmas MFD node and regulator nodes)
introduced regulator entries for OMAP5uEVM.

However, The regulator information is based on an older temporary
pre-production board variant and does not reflect production board
750-2628-XXX boards.

The following optional/unused regulators can be updated:

- SMPS9 supplies TWL6040 over VDDA_2v1_AUD. This regulator needs to be
enabled only when audio is active. Since it does not come active by
default, it does not require "always-on" or "boot-on".

- LDO2 and LDO8 do not go to any peripheral or connector on the board.
Further, these unused regulators should have been 2.8V for LDO2 and
3.0V for LDO8. Mark these LDOs as disabled in the dts until needed.

e18235a62a ARM: dts: omap5-uevm: fix regulator configurations mandatory for SoC
commit e00c27ef3b
(ARM: dts: OMAP5: Add Palmas MFD node and regulator nodes)
introduced regulator entries for OMAP5uEVM.

However, The regulator information is based on an older temporary
pre-production board variant and does not reflect production board
750-2628-XXX boards.

The following fixes are hence mandatory to ensure right voltage is
supplied to key OMAP5 SoC voltage rails:

- LDO1 supplies VDDAPHY_CAM which is OMAP5's vdda_csiporta/b/c. This
can only be supplied at 1.5V or 1.8V and we currently supply 2.8V.

To prevent any potential device damage risk, use the specified
1.5V-1.8V supply.

Remove 'always-on' and 'boot-on' settings here as it is
a 'on need' supply to SoC IP and is not enabled by PMIC by
default at boot.

- LDO3 supplies Low Latency Interface(LLI) hardware module which is a
special hardware to communicate with Modem. However since uEVM is
not setup by default for this communication, this should be disabled
by default.

Further, vdda_lli is supposed to be 1.5V and not 3V.

- LDO4 supplies VDDAPHY_DISP which is vdda_dsiporta/c/vdda_hdmi

This can only be supplied at 1.5V or 1.8V and we currently
supply 2.2V.

To prevent any potential device damage risk, use the specified
1.5V-1.8V supply.

Remove 'always-on' and 'boot-on' settings here as it is a 'on need'
supply to SoC IP and is not enabled by PMIC by default at boot.

- LDO6 supplies the board specified VDDS_1V2_WKUP supply going to
ldo_emu_wkup/vdds_hsic. To stay within the SoC specification supply
1.2V instead of 1.5V.

- LDO7 supplies VDD_VPP which is vpp1. This is currently configured for
1.5V which as per data manual "A pulse width of 1000 ns and an amplitude
of 2V is required to program each eFuse bit. Otherwise, VPP1 must not
be supplied".

So, fix the voltage to 2V. and disable the supply since we have no plans
of programming efuse bits - it can only be done once - in factory.

Further it is not enabled by default by PMIC so, 'boot-on' must be
removed, and the 'always-on' needs to be removed to achieve pulsing
if efuse needs to be programmed.

- LDO9 supplies the board specified vdds_sdcard supply going within SoC
specification of 1.8V or 3.0V. Further the supply is controlled by
switch enabled by REGEN3. So, introduce REGEN3 and map sdcard slot to
be powered by LDO9. Remove 'always-on' allowing the LDO to be disabled
on need basis.

commit e00c27ef3b
(ARM: dts: OMAP5: Add Palmas MFD node and regulator nodes)
introduced regulator entries for OMAP5uEVM.

However, currently we use the Palmas regulator names which is used for
different purposes on uEVM. Document the same based on 750-2628-XXX
boards - which is meant to be supported by this dts.

Booting omap5 uevm results in the following error
"did not get pins for uart error: -19"

This happens because omap5 uevm dts file is not adapted
to use uart through pinctrl framework.
Populate uart pinctrl data to get rid of the error.

fa63d03728 ARM: dts: omap5: Make uevm as the official board and deprecate sevm support
The uevm is the only official board supported for the OMAP5 soc
in mainline. The existent sevm platform will no more be supported.
Hence cleaning up the board dts file to have only the data
required for uevm.

Renaming the board dts file and adding the following cleanups.

 * There are no devices connected on I2C 2,3,4 buses. So remove
   the pinmux data for the same.

 * OMAP5432 and DDR3 memory is used in the uevm. Temperature polling
   is not supported with DDR3 memories. Because of DDR3 phy limitation
   the voltage change across DVFS and all shadow registers for DVFS on
   DDR3 is not supported. Hence the emif kernel driver is not required,
   so removing the DDR3 device file and emif nodes for uevm.

 * Keypad is not supported on uevm. So remove the device node.
