Commit b158b69a3765 ("mfd: rtsx: Simplify function return logic")
removed the use of the 'err' variable, but left the variable itself
around, resulting in gcc quite reasonably warning:
drivers/mfd/rtsx_pcr.c: In function ‘rtsx_pci_set_pull_ctl’:
drivers/mfd/rtsx_pcr.c:565:6: warning: unused variable ‘err’ [-Wunused-variable]
int err;
^
Get rid of the unused variable, and avoid the new warning.

Pull regulator updates from Mark Brown:
"This is quite a quiet release in terms of volume of patches but it
includes a couple of really nice core changes - the work Sascha has
done in particular is something I've wanted to get done for a long
time but just never got round to myself.
Highlights include:
- Support from Sascha Hauer for setting the voltage of parent
supplies based on requests from their children. This is used both
to allow set_voltage() to work through a dumb switch and to improve
the efficiency of systems where DCDCs are used to supply LDOs by
minimising the voltage drop over the LDOs.
- Removal of regulator_list by Tomeu Vizoso, meaning we're not
duplicating the device list maintained by the driver core.

The commit 54e8827d5f0e ("mfd: sec-core: Add support for S2MPU02
device") added new MFD child devices for S2MPU02: RTC and clock
provider (the clock provider with new compatible). However support for
these devices was not added to existing drivers (rtc-s5m, clk-s2mps11).
New drivers were not submitted neither.
This means that the name of children devices is completely unused. The
"samsung,s2mpu02-clk" compatible remains undocumented so it is unclear
what is provided by that compatible.
Clean up this by removing unused child devices and undocumented
compatible.

The WRSTBI bit (disabled by default but enabled by bootloader), when
set, is responsible for resetting voltages to default values of
certain bucks on falling edge of Warm Reset Input pin from AP.
However on some boards (with S2MPS13) the pin is pulled down so any
suspend will effectively trigger the reset of bucks supplying the power
to the little and big cores. In the same time when resuming, these bucks
must provide voltage greater or equal to voltage before suspend to match
the frequency chosen by cpufreq. If voltage (default value of voltage
after reset) is lower than one set by cpufreq before suspend, then
system will hang during resuming.

In the case of a device tree config the code uses the device ID

Remove the use of #ifdefs around each case statement of the chip ID
and type validation switches.
We must ensure that the contained code still compiles to nothing if
support for that codec was not built into the kernel, to prevent
creation of link references to missing functions. So the ifdefs are

This driver supports the new Atmel Flexcom. The Flexcom is a wrapper which
integrates one SPI controller, one I2C controller and one USART. Only one
function can be enabled at a time. This driver selects the function once
for all, when the Flexcom is probed, according to the value of the new
"atmel,flexcom-mode" device tree property.
This driver has chosen to present the Flexcom to the system as a MFD so
the implementation is seamless for the existing Atmel SPI, I2C and USART
drivers.
Also the Flexcom embeds FIFOs: the latest patches of the SPI, I2C and
USART drivers take advantage of this new feature.

tps6105 driver provides two cells. One is for GPIO and another one is

GPIO-only mode, this driver calls mfd_add_devices() with mfd_cell
.name == NULL. This value causes an oops in platform_device_register()
later.

On Odroid XU3 board (with S2MPS11 PMIC) the PWRHOLD bit in CTRL1
register must be manually set to 0 before initiating power off sequence.
One of usual power down methods for Exynos based devices looks like:
1. PWRHOLD pin of PMIC is connected to PSHOLD of Exynos SoC.
2. Exynos holds up this pin during system operation.
3. ACOKB pin of PMIC is pulled up to VBATT and optionally to pin in
other device.
4. When PWRHOLD/PSHOLD goes low, the PMIC will turn off the power if
ACOKB goes high.
On Odroid XU3 family the difference is in (3) - the ACOKB is grounded.
This means that PMIC must manually set PWRHOLD field to low and then
wait for signal from Application Processor (the usual change in
PWRHOLD/PSHOLD pin will actually cut off the power).
The patch adds respective binding allowing Odroid XU3 device to be
powered off.
