The ABI allows for enumeration of the available power partitions, so the driver can be reused on future generations, provided the BPMP ABI remains stable.

2017-06-12soc: renesas: Rework Kconfig and Makefile logicGeert Uytterhoeven
The goals are to: - Allow precise control over and automatic selection of which (sub)drivers are used for which SoC, - Allow adding support for new SoCs easily, - Allow compile-testing of all (sub)drivers, - Keep driver selection logic in the subsystem-specific Kconfig, independent from the architecture-specific Kconfig (i.e. no "select" from arch/arm64/Kconfig.platforms), to avoid dependencies. This is implemented by: - Introducing Kconfig symbols for all drivers and sub-drivers, - Introducing the Kconfig symbol SOC_RENESAS, which is enabled automatically when building for a Renesas ARM platform, and which enables all required drivers without interaction of the user, based on SoC-specific ARCH_* symbols, - Allowing the user to enable any Kconfig symbol manually if COMPILE_TEST is enabled, - Using the new Kconfig symbols instead of the ARCH_* symbols to control compilation in the Makefile, - Always entering drivers/soc/renesas/ during the build.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC fixes from Olof Johansson: "We had a small batch of fixes before -rc1, but here is a larger one. It contains a backmerge of 4.12-rc1 since some of the downstream branches we merge had that as base; at the same time we already had merged contents before -rc1 and rebase wasn't the right solution. A mix of random smaller fixes and a few things worth pointing out: - We've started telling people to avoid cross-tree shared branches if all they're doing is picking up one or two DT-used constants from a shared include file, and instead to use the numeric values on first submission. Follow-up moving over to symbolic names are sent in right after -rc1, i.e. here. It's only a few minor patches of this type. - Linus Walleij and others are resurrecting the 'Gemini' platform, and wanted a cut-down platform-specific defconfig for it. So I picked that up for them. - Rob Herring ran 'savedefconfig' on arm64, it's a bit churny but it helps people to prepare patches since it's a pain when defconfig and current savedefconfig contents differs too much. - Devicetree additions for some pinctrl drivers for Armada that were merged this window. I'd have preferred to see those earlier but it's not a huge deail. The biggest change worth pointing out though since it's touching other parts of the tree: We added prefixes to be used when cross-including DT contents between arm64 and arm, allowing someone to #include <arm/foo.dtsi> from arm64, and likewise. As part of that, we needed arm/foo.dtsi to work on arm as well. The way I suggested this to Heiko resulted in a recursive symlink. Instead, I've now moved it out of arch/*/boot/dts/include, into a shared location under scripts/dtc. While I was at it, I consolidated so all architectures now behave the same way in this manner. Rob Herring (DT maintainer) has acked it. I cc:d most other arch maintainers but nobody seems to care much; it doesn't really affect them since functionality is unchanged for them by default" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (29 commits) arm64: dts: rockchip: fix include reference firmware: ti_sci: fix strncat length check ARM: remove duplicate 'const' annotations' arm64: defconfig: enable options needed for QCom DB410c board arm64: defconfig: sync with savedefconfig ARM: configs: add a gemini defconfig devicetree: Move include prefixes from arch to separate directory ARM: dts: dra7: Reduce cpu thermal shutdown temperature memory: omap-gpmc: Fix debug output for access width ARM: dts: LogicPD Torpedo: Fix camera pin mux ARM: dts: omap4: enable CEC pin for Pandaboard A4 and ES ARM: dts: gta04: fix polarity of clocks for mcbsp4 ARM: dts: dra7: Add power hold and power controller properties to palmas soc: imx: add PM dependency for IMX7_PM_DOMAINS ARM: dts: imx6sx-sdb: Remove OPP override ARM: dts: imx53-qsrb: Pulldown PMIC IRQ pin soc: bcm: brcmstb: Correctly match 7435 SoC tee: add ARM_SMCCC dependency ARM: omap2+: make omap4_get_cpu1_ns_pa_addr declaration usable ARM64: dts: mediatek: configure some fixed mmc parameters ...

2017-04-30soc/fsl/qbman: Disable IRQs for deferred QBMan workRoy Pledge
Work for Congestion State Notifications (CSCN) and Message Ring (MR) handling is handled via the workqueue mechanism. This requires the driver to disable those IRQs before scheduling the work and re-enabling it once the work is completed so that the interrupt doesn't continually fire.

2017-04-30soc/fsl/qe: only apply QE_General4 workaround on affected SoCsValentin Longchamp
The QE_General4 workaround is only valid for the MPC832x and MPC836x SoCs. The other SoCs that embed a QUICC engine are not affected by this hardware bug and thus can use the computed divisors (this was successfully tested on the T1040). Similalry to what was done in commit 8ce795cb0c6b ("i2c: mpc: assign the correct prescaler from SVR") in order to avoid changes in the device tree nodes of the QE (with maybe a variant of the compatible property), the PVR reg is read out to find out if the workaround must be applied or not.

2017-04-30soc/fsl/qe: round brg_freq to 1kHz granularityValentin Longchamp
Because of integer computation rounding in u-boot (that sets the QE brg-frequency DTS prop), the clk value is 99999999 Hz even though it is 100 MHz. When setting brg clks that are exact divisors of 100 MHz, this small differnce plays a role and can result in lower clks to be output (for instance 20 MHz - divide by 5 - results in 16.666 MHz - divide by 6). This patch fixes that by "forcing" the brg_clk to the nearest kHz when the difference is below 2 integer rounding errors (i.e. 4).
