soc: mediatek: add dependent clock jpgdec/audio for scpsys

2017-12-21T10:49:23+00:00

There are dependent clock jpgdec/audio in scpsys on MT2712,
and will exist three dependent clocks on MT2712 VDEC.

soc: mediatek: extend bus protection API

2017-12-21T10:49:22+00:00

MT2712 add "set/clear" bus control register to each control register set
instead of providing only one "enable" control register, we could avoid
the read-modify-write racing by declaring "bus_prot_reg_update" as "false"
in scp_soc_data or declaring as "true" to use the legacy update method.
By improving the mtk-infracfg bus protection implementation to
support set/clear bus protection control method by IC configuration.

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 ]

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:

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.
