Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2017-11-17T00:05:01+00:00

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 ]

soc: mediatek: Use GENPD_FLAG_ACTIVE_WAKEUP

Set the newly introduced GENPD_FLAG_ACTIVE_WAKEUP, which allows to
remove the driver's own flag-based callback.

soc: mediatek: pwrap: fix fatal compiler error

2017-10-21T08:23:28+00:00

When adding the MT6380 compatible, the sentinel for of_device_id was
deleted, which leades to the following compiler error:
FATAL: drivers/soc/mediatek/mtk-pmic-wrap: struct of_device_id is not terminated with a NULL entry!

Fix this by adding the sentinel again.

When compiling using sparse, we got the following error:
drivers/soc/mediatek/mtk-pmic-wrap.c:686:25: error: dubious one-bit signed bitfield

Changing the data type to unsigned fixes this.

soc: mediatek: place Kconfig for all SoC drivers under menu

2017-10-20T10:08:01+00:00

Add cleanup for placing all Kconfig for all MediaTek SoC drivers under
the independent menu as other SoCs vendor usually did. Since the menu
would be shown depending on "ARCH_MEDIATEK || COMPILE_TEST" selected and
MTK_PMIC_WRAP is still safe compiling with the case of "COMPILE_TEST"
only, the superfluous dependency for those items under the menu also is
also being removed for the sake of simplicity.

soc: mediatek: pwrap: add common way for setup CS timing extenstion

2017-10-20T09:54:38+00:00

Multiple platforms would always use their own way handling CS timing
extension on the bus which leads to a little bit code duplication.
Therefore, the patch groups the similar logic to handle CS timing
extension into the common function which allows the following SoCs
have more reusability for configing CS timing.

Add MediaTek MT6380 regulator becoming one of PMIC wrapper slave
and also add extra new regmap_config of 32-bit mode for MT6380
since old regmap_config of 16-bit mode can't be fit into the need.

soc: mediatek: pwrap: refactor pwrap_init for the various PMIC types

2017-10-20T09:54:37+00:00

pwrap initialization is highly associated with the base SoC and the
target PMICs, so slight refactorization is made here for allowing
pwrap_init to run on those PMICs with different capability from the
previous MediaTek PMICs and the determination for the enablement of the
pwrap capability depending on PMIC type. Apart from this, the patch
makes the driver more extensible especially when more PMICs join into
the pwrap driver.

soc: mediatek: pwrap: add pwrap_write32 for writing in 32-bit mode

2017-10-20T09:54:37+00:00

Some regulators such as MediaTek MT6380 also has to be written in
32-bit mode. So the patch adds pwrap_write32, rename old pwrap_write
into pwrap_write16 and one additional function pointer is introduced
for increasing flexibility allowing the determination which mode is
used by the pwrap slave detection through device tree.
