I'm asking because we need a huge immutable branch (I guess in the MFD subsystem) to deal with that. It'd be great if I could just apply the pinctrl patches in isolation, then Lee applies the MFD patches in isolation, everything compiles in isolation but maye just work once both pinctrl and MFD are merged upstream, as in linux-next or Torvalds' tree. That is one of the reasons why using a system-agnostic syscon regmap lookup is so good, BTW.

Hello, This patchset is a first step to add support for all power domains on Exynos5433 SoCs. This patchset contains patches for Exynos pin control driver and Exynos LPASS MFD driver, which are needed to make the platform ready for adding power domains support. Patches in this patchset depends on each other. They are order in such a way to make the changes bisectable. Patch #3 has runtime dependency on #1. Patch #5 has runtime dependency on #3. Patch #6 has runtime dependency on #4. This patchset also directly depends on the "Move pad retention control to Exynos pin controller driver" patchset: https://www.spinics.net/lists/arm-kernel/msg556074.html Patches have been generated on top of linux-next from 25th January 2017. This is a part of a larger task, which goal is to add support for power domains on Exynos5433 SoCs / TM2 boards. All patches needed to get it working have been pushed to the following git repo: https://git.linaro.org/people/marek.szyprowski/linux-srpol.git v4.10-next-tm2-pd Best regards Marek Szyprowski Samsung R&D Institute Poland Changelog: v2: - fixed issues pointed by Krzysztof Kozlowski: 1. added more checks to Exynos PMU driver for NULL drvdata 2. reused EXYNOS_WAKEUP_FROM_LOWPWR in retention data for Exynos5433 3. converted lpass driver to devm_clk_get 4. added missing ->remove callback to lpass driver v1: https://lkml.org/lkml/2017/1/25/214 - initial version Patch summary: Marek Szyprowski (8): soc: samsung: pmu: Add dummy support for Exynos5433 SoC pinctrl: samsung: Ensure that pad retention is disabled on driver init pinctrl: samsung: Add support for pad retention control for Exynos5433 SoCs arm64: dts: exynos: Add clocks to Exynos5433 LPASS module mfd: exynos-lpass: Remove pad retention control mfd: exynos-lpass: Add support for clocks mfd: exynos-lpass: Add missing remove() function mfd: exynos-lpass: Add runtime PM support .../bindings/mfd/samsung,exynos5433-lpass.txt | 8 ++- arch/arm64/boot/dts/exynos/exynos5433.dtsi | 2 + drivers/mfd/exynos-lpass.c | 48 ++++++++++------- drivers/pinctrl/samsung/pinctrl-exynos.c | 63 ++++++++++++++++++++++ drivers/soc/samsung/exynos-pmu.c | 6 ++- include/linux/mfd/syscon/exynos5-pmu.h | 3 -- include/linux/soc/samsung/exynos-regs-pmu.h | 16 ++++++ 7 files changed, 121 insertions(+), 25 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
