Pull MMC updates from Ulf Hansson:
"This time, this pull request contains changes crossing subsystems and
archs/platforms, which is mainly because of a bigger modernization of
moving from legacy GPIO to GPIO descriptors for MMC (by Linus
Walleij).
Additionally, once again, I am funneling changes to

Enable PCI suspend/resume support on imx6sx SOCs. This is similar to
imx7d with a few differences:
* The PM_Turn_Off bit is exposed through an IOMUX GPR, like all other
pcie control bits on 6sx.
* The pcie_inbound_axi clk needs to be turned off in suspend. On resume
it is restored via resume -> deassert_core_reset -> enable_ref_clk.
Most of the resume logic is shared with the initial reset after probe.

The TMIO MMC driver was passing global GPIO numbers around for
card detect. It turns out only one single board in the kernel
was actually making use of this feature so it is pretty easy
to convert the driver to use only GPIO descriptors.
The lines are flagged as GPIO_ACTIVE_[LOW|HIGH] as that is
what they are, and since we can now rely on the descriptors
to have the right polarity, we set the
"override_active_level" to false in mmc_gpiod_request_cd()
and mmc_gpiod_request_ro().

When performing single ended measurements with TSCADC, its recommended
to set negative input (SEL_INM_SWC_3_0) of ADC step to ADC's VREFN in the
corresponding STEP_CONFIGx register.
Also, the positive(SEL_RFP_SWC_2_0) and negative(SEL_RFM_SWC_1_0)
reference voltage for ADC step needs to be set to VREFP and VREFN
respectively in STEP_CONFIGx register.
Without these changes, there may be variation of as much as ~2% in the
ADC's digital output which is bad for precise measurement.

Instead of passing a global GPIO number for the enable GPIO, pass
a descriptor looked up from the device tree node or the board file
decriptor table for the regulator.
There is a single board file passing the GPIOs for LDO1 and LDO2
through platform data, so augment this to pass descriptors
associated with the i2c device as well.
The special GPIO enable DT property for the enable GPIO is
nonstandard but this was accomodated in
commit 6a537d4846
"gpio: of: Support regulator nonstandard GPIO properties".

cros_ec_get_next_event() is documented to return 0 for success and
negative for errors. It currently returns negative for some errors, and
non-negative (number of bytes received) for success (including some "no
data available" responses as zero). This mostly works out OK, because the
callers were more or less ignoring the documentation, and only treating
positive values as success (and indepdently checking the modification of
'wakeup').
Let's button this up by avoiding pretending to handle event/wakeup
distinctions when no event info was retrieved (i.e., returned 0 bytes).
And fix the documentation of cros_ec_get_host_event() and
cros_ec_get_next_event() to accurately describe their behavior.

IRQ wake up support for MAX8997 driver was initially configured by
respective property in pdata. However, after the driver conversion to
device-tree, setting it was left as 'todo'. Nowadays most of other PMIC MFD
drivers initialized from device-tree assume that they can be an irq wakeup
source, so enable it also for MAX8997. This fixes support for wakeup from
MAX8997 RTC alarm.

After debugging this issue and comparing the MC13892 and MC13783
initializations done in the vendor kernel, it was noticed that the
CHRGRAWDIV bit of the ADC0 register was not being set.
This bit is set by default after power on, but the driver was
clearing it.
After setting this bit it is possible to read the ADC values correctly.
