Pull ARM SoC platform updates from Arnd Bergmann:
"These are mostly minor bugfixes, cleanup and many defconfig updates to
support added drivers. In particular OMAP and PXA keep cleaning up the
legacy code base, as usual.
Nvidia adds some more SoC support code for Tegra 186.
For the first time on years, we are actually adding a non-DT platform
for the EP93xx based Liebherr controller BK3.1. It's a minor variation
of the EP93xx reference design and in active use, while EP93xx
apparently doesn't have enough new development to have any device tree
support"

Restructure mlxreg header for unification of hotplug item definitions.
Unify hotplug items to allow any kind of item (power controller, fan
eeprom, psu eeprom, asic health) in common way.
Use a hardware independent regmap interface, enabling the support of
hotplug events over programmable devices attached to different bus
types, such as I2C, LPC, or SPI. Add a device node to the

"AT24 updates for 4.16 merge window
The driver has been converted to using regmap instead of raw i2c and
smbus calls which shrank the code significantly.
Device tree binding document has been cleaned up. Device tree support in
the driver has been improved and we now support all at24 models as well
as two new DT properties (no-read-rollover and wp-gpios).
We no longer user unreadable magic values for driver data as the way it
was implemented caused problems for some EEPROM models - we switched to
regular structs.
Aside from that, there's a bunch of coding style fixes and minor
improvements all over the place."
Replace spaces with tabs in the definition of AT24_FLAG_NO_RDROL.
Fixes: 9d404411091c ("eeprom: at24: support eeproms that do not auto-rollover reads")
Signed-off-by: Bartosz Golaszewski <brgl@bgdev.pl>
Some multi-address eeproms in the at24 family may not automatically
roll-over reads to the next slave address. On those eeproms, reads
that straddle slave boundaries will not work correctly.
Solution:
Mark such eeproms with a flag that prevents reads straddling
slave boundaries. Add the AT24_FLAG_NO_RDROL flag to the eeprom
entry in the device_id table, or add 'no-read-rollover' to the
eeprom devicetree entry.
Note that I have not personally enountered an at24 chip that
does not support read rollovers. They may or may not exist.
However, my hardware requires this functionality because of
a quirk.

We can easily detect i2c based on it's non-standard module registers that

We want to be able to configure hwmod sysc data from ti-sysc driver using
platform data callbacks. So let's make struct omap_hwmod_sysc_fields into
struct sysc_data and have it available for both ti-sysc driver and hwmod
code.
Note that we can make it use s8 instead of u8 as the hwmod code uses the
feature flags to check for this field. However, for ti-sysc we can use
-ENODEV to indicate a feature is not supported in the hardware and can
simplify the code that way.
And let's add also emufree_shift as the dts files will be describing the
hardware for the SYSCONFIG register capbilities mask.

Pull ARM SoC driver updates from Arnd Bergmann:
"This branch contains platform-related driver updates for ARM and
ARM64, these are the areas that bring the changes:
New drivers:
- driver support for Renesas R-Car V3M (R8A77970)
- power management support for Amlogic GX
- a new driver for the Tegra BPMP thermal sensor
- a new bus driver for Technologic Systems NBUS
Changes for subsystems that prefer to merge through arm-soc:
- the usual updates for reset controller drivers from Philipp Zabel,
with five added drivers for SoCs in the arc, meson, socfpa,
uniphier and mediatek families
- updates to the ARM SCPI and PSCI frameworks, from Sudeep Holla,
Heiner Kallweit and Lorenzo Pieralisi
Changes specific to some ARM-based SoC
- the Freescale/NXP DPAA QBMan drivers from PowerPC can now work on
ARM as well
- several changes for power management on Broadcom SoCs
- various improvements on Qualcomm, Broadcom, Amlogic, Atmel,
Mediatek
- minor Cleanups for Samsung, TI OMAP SoCs"
[ NOTE! This doesn't work without the previous ARM SoC device-tree pull,
because the R8A77970 driver is missing a header file that came from
that pull.
The fact that this got merged afterwards only fixes it at this point,
and bisection of that driver will fail if/when you walk into the
history of that driver. - Linus ]
