Enabling Exynos850 support in the PD driver is really just a matter of adding: static const struct exynos_pm_domain_config exynos850_cfg = { .local_pwr_cfg = 0x1, }; to the driver. But in the face of recent developments, e.g. this patch: arm64: dts: exynos: move MIPI phy to PMU node in Exynos5433 it looked logical to rework the PD driver a bit to support its nesting under the PMU node, while adding Exynos850 support to it. Initially I only wanted to add syscon regmap support via some dedicated property, but pulling PD nodes under the PMU syscon looks like more correct way. This patch series provides next changes: 1. Make it possible for PD nodes to be children of PMU 2. Add Exynos850 support to PD driver 3. A bit of refactoring in PD driver 4. Corresponding changes to dt-bindings Dependencies inside of the series: - patch #2 depends on patch #1 - patch #6 depends on patch #1 - patches 3,4,5,6 should be applied in the same order as in the series Sam Protsenko (6): dt-bindings: power: pd-samsung: Add Exynos850 support dt-bindings: power: pd-samsung: Allow pd nodes to be children of PMU soc: samsung: pm_domains: Extract DT handling into a separate function soc: samsung: pm_domains: Implement proper I/O operations soc: samsung: pm_domains: Allow PD to be a child of PMU syscon soc: samsung: pm_domains: Add Exynos850 support .../devicetree/bindings/power/pd-samsung.yaml | 12 +- MAINTAINERS | 1 + drivers/soc/samsung/Kconfig | 1 + drivers/soc/samsung/pm_domains.c | 132 +++++++++++++++--- .../power/samsung,exynos850-power.h | 17 +++ 5 files changed, 142 insertions(+), 21 deletions(-) create mode 100644 include/dt-bindings/power/samsung,exynos850-power.h
