This includes mfd-core.c and vexpress-sysreg.c which, although they
did not produce a warning with the x86 allmodconfig configuration, may
cause this warning with other configurations.

Add another batch of various "simple" syscon compatibles which were
undocumented or still documented with old text bindings. Remove the old

The driver has intel_lpss_platform_info structs for I2C, SPI, and UART.
The I2C and UART structs are named with "i2c" and "uart" in the variable
name, whereas SPI ones do not mention "spi".
Rename the SPI related info structs to include "spi" in their names for
consistency and to make it obvious in the device ID list what kind of
device the line relates to.

Linking a file into two modules can have unintended side-effects
and produces a W=1 warning:
scripts/Makefile.build:236: drivers/mfd/Makefile: rsmu_core.o is added to multiple modules: rsmu-i2c rsmu-spi

The primary use of the CRC PMIC's PWM is for LCD panel backlight
control by the i915 driver.
Due to its complexity the probe() function of the i915 driver does not
support -EPROBE_DEFER handling. So far the pwm-crc driver must be built
into the kernel to ensure that the pwm_get() done by the i915 driver
succeeds at once (rather then returning -EPROBE_DEFER).
But the PWM core can load the module from pwm_get() if a module-name is
provided in the pwm_lookup associated with the consumer device.
Switch to using PWM_LOOKUP_WITH_MODULE() for the lookup added for
the Intel integrated GPU, so that the PWM core can load the module from
pwm_get() as needed allowing the pwm-crc driver to be safely built as
module.
This has been successfully tested on an Asus T100TAM with pwm-crc
build as a module.

Add a new mediatek,mt8365-scpsys compatible, for the SCPSYS syscon block
having power controller. Previously the DTS was re-using SYSCFG
compatible, but that does not seem right, because SYSCFG does not have
children.

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.
While add it, also remove commas after the sentinel entries.
