dda922c831 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts:
	drivers/net/phy/amd-xgbe-phy.c
	drivers/net/wireless/iwlwifi/Kconfig
	include/net/mac80211.h

iwlwifi/Kconfig and mac80211.h were both trivial overlapping
changes.

The drivers/net/phy/amd-xgbe-phy.c file got removed in 'net-next' and
the bug fix that happened on the 'net' side is already integrated
into the rest of the amd-xgbe driver.

e0c21530fa mfd: da9052: Fix broken regulator probe
Fix broken probe of da9052 regulators, which since commit b3f6c73db7
("mfd: da9052-core: Fix platform-device id collision") use a
non-deterministic platform-device id to retrieve static regulator
information. Fortunately, adequate error handling was in place so probe
would simply fail with an error message.

Update the mfd-cell ids to be zero-based and use those to identify the
cells when probing the regulator devices.

6d4fa89dcd mfd: axp20x: Enable AXP22X regulators
Now that the axp20x-regulators driver supports different variants of the
AXP family, we can enable regulator support for AXP22X without the risk
of incorrectly configuring regulators.

f05be589ff mfd: axp20x: Add AXP22x PMIC support
Add support for the AXP22x PMIC devices to the existing AXP20x driver.
This includes the AXP221 and AXP223, which are identical except for
the external data bus. Only AXP221 is added for now. AXP223 will be
added after it's Reduced Serial Bus (RSB) interface is supported.

AXP22x defines a new set of registers, power supplies and regulators,
but most of the API is similar to the AXP20x ones.

A new irq chip definition is used, even though the available interrupts
on AXP22x is a subset of those on AXP20x. This is done so the interrupt
numbers match those on the datasheet.

This patch only enables the interrupts, system power-off function, and PEK
sub-device. The regulator driver must first support different variants
before we enable it from the mfd driver.

844e0edf42 can: janz-ican3: add support for CAL/CANopen firmware
In our department we are using some older Janz ICAN3-modules in our dekstop
pcs. There we have slightly different carrier boards than the janz-cmodio
supported in the kernel sources, called CAN-PCI2 with two submodules. But the
pci configuration regions are identical. So extending the supported pci devices
to the corresponding device ids is sufficient to get the drivers working.

* The old ICAN3-modules with firmware 1.28 need more then 250ms for the restart
  after reset. I've increased the timeout to 500ms.
* The janz_ican3 module uses the raw can services of the Janz-firmware, this
  means firmware must be ICANOS/2. Our ICAN3-modules are equipped with
  CAL/CANopen-firmware, so I must use the appropriate commands for the layer
  management services.

Te driver detects the firmware after module reset and selects the commands
matching the firmware. This affects the bus on/off-command
(ican3_set_bus_state) and the configuration of the bittiming
(ican3_set_bittiming). For better diagnostics the detected firmware string is
presented as sysfs attribute (fwinfo).

36a8032d77 platform/chrome: Updates for v4.1
Here's a set of updates to the Chrome OS platform drivers for this merge window.
 
 Main new things this cycle is:
 
 - Driver changes to expose the lightbar to users. With this, you can make your
   own blinkenlights on Chromebook Pixels.
 - Changes in the way that the atmel_mxt trackpads are probed. The laptop driver
   is trying to be smart and not instantiate the devices that don't answer to
   probe. For the trackpad that can come up in two modes (bootloader or regular),
   this gets complicated since the driver already knows how to handle the two
   modes including the actual addresses used. So now the laptop driver needs to
   know more too, instantiating the regular address even if the bootloader one
   is the probe that passed.
 - mfd driver improvements by Javier Martines Canillas, and a few bugfixes
   from him, kbuild and myself.

e554a99ee8 mfd: sec: Fix RTC alarm interrupt number on S2MPS11
The RTC on S2MPS11 is the same as S2MPS14. However interrupt numbers of
RTC alarms 0 and 1 were inversed between these two devices. So when
rtc-s5m driver requested S2MPS14_IRQ_RTCA0 interrupt, it matched to
S2MPS11_IRQ_RTCA1, not RTCA0.

Fix this by using consistent RTC alarm interrupt numbers and adding a
BUILD_BUG_ON for future generations.

a77c50b44c mfd: core: Fix platform-device name collisions
Since commit 6e3f62f079 ("mfd: core: Fix platform-device id
generation") we honour PLATFORM_DEVID_AUTO and PLATFORM_DEVID_NONE when
registering mfd-devices.

Unfortunately, some mfd-drivers rely on the old behaviour of generating
platform-device ids by adding the cell id also to the special value of
PLATFORM_DEVID_NONE. The resulting platform ids are not only used to
generate device-unique names, but are also used instead of the cell id
to identify cells when probing subdevices.

These drivers should be updated to use PLATFORM_DEVID_AUTO, which would
also allow more than one device to be registered without resorting to
hacks (see for example wm831x), but lets fix the regression first by
partially reverting the above mentioned commit with respect to
PLATFORM_DEVID_NONE.

Fixes: 6e3f62f079 ("mfd: core: Fix platform-device id generation")

b10848e6f9 mfd: ti_am335x_tscadc: Remove unwanted reg_se_cache save
In one shot mode, sequencer automatically disables all enabled steps at
the end of each cycle. (both ADC steps and TSC steps) Hence these steps
need not be saved in reg_se_cache for clearing these steps at a later
stage.
Also, when ADC wakes up Sequencer should not be busy executing any of the
config steps except for the charge step. Previously charge step was 1 ADC
clock cycle and hence it was ignored.
TSC steps are always disabled at the end of each conversion cycle, hence
there is no need to explicitly disable TSC steps by writing 0 to REG_SE.

1b84f2a4cd mfd: cros_ec: Use fixed size arrays to transfer data with the EC
The struct cros_ec_command will be used as an ioctl() argument for the
API to control the ChromeOS EC from user-space. So the data structure
has to be 64-bit safe to make it compatible between 32 and 64 avoiding
the need for a compat ioctl interface. Since pointers are self-aligned
to different byte boundaries, use fixed size arrays instead of pointers
for transferring ingoing and outgoing data with the Embedded Controller.

Also, re-arrange struct members by decreasing alignment requirements to
reduce the needing padding size.

A card insertion happens after the lastest polling before reader is
suspended may never have a chance to be detected. Under current 1-HZ
polling interval setting in mmc_core, the worst case of such
undetectablility is about 1 second.

To further reduce the undetectability, detect card slot again in suspend
method and defer the autosuspend if the slot is loaded. The default 2
second autosuspend delay of USB subsystem should let the next polling
detects the card.

2b50635ea3 mfd: max77686/802: Remove support for board files
The driver is used only on Exynos based boards with DTS support.
After removal of board file support from max77686 and max77802 regulator
drivers, the MFD driver can be converted to DTS-only version. This
simplifies a little the code:
1. No dead (unused) entries in platform_data structure.
2. More code removed.
3. Regulator driver does not depend on allocated memory
   from MFD driver.
4. It makes also easier extending the regulator driver.

Add to the max77686 MFD driver dependency on CONFIG_OF because without
DTS the regulator drivers (max77686 and max77802) won't bind.

3daa122d6b mfd: dln2: Add suspend/resume functionality
Without suspend/resume functionality in the USB driver the USB core
will disconnect and reconnect the DLN2 port and because the GPIO
framework does not yet support removal of an in-use controller a
suspend/resume operation will result in a crash.

This patch provides suspend and resume functions for the DLN2 driver
so that the above scenario is avoided, if the host controller does not
drop VBUS during suspend, since in this case the device state is
preserved.

We chose not implemented reset_resume so that if the host controller
does drop VBUS the resume path will go through above the
disconnect/reconnect process since it is probably better to fix the
GPIO framework disconnect issue then to save and restore the device
state for every driver.

b166010f6a mfd: rtsx_usb: Fix runtime PM deadlock
sd_set_power_mode() in derived module drivers/mmc/host/rtsx_usb_sdmmc.c
acquires dev_mutex and then calls pm_runtime_get_sync() to make sure the
device is awake while initializing a newly inserted card. Once it is
called during suspending state and explicitly before rtsx_usb_suspend()
acquires the same dev_mutex, both routine deadlock and further hang the
driver because pm_runtime_get_sync() waits the pending PM operations.

Fix this by using an empty suspend method. mmc_core always turns the
LED off after a request is done and thus it is ok to remove the only
rtsx_usb_turn_off_led() here.

f29ae369a4 mfd: tps65218: Make INT1 our status_base register
If we don't tell regmap-irq that our first status
register is at offset 1, it will try to read offset
zero, which is the chipid register.

773328da24 mfd: tps65218: Make INT[12] and STATUS registers volatile
STATUS register can be modified by the HW, so we
should bypass cache because of that.

In the case of INT[12] registers, they are the ones
that actually clear the IRQ source at the time they
are read. If we rely on the cache for them, we will
never be able to clear the interrupt, which will cause
our IRQ line to be disabled due to IRQ throttling.
