The G12A & G12B SoCs has kernel controllable CPU clocks and PWMs for voltage regulators.
This patchsets moves the meson-g12a.dtsi to meson-g12-common.dtsi to simplify handling the G12A & G12B differences in the meson-g12a.dtsi & meson-g12b.dtsi files, like the OPPs and CPU nodes. Then G12A & G12B OPP tables are added, followed by the CPU voltages regulators in each boards DT. It was voluntary chosen to enabled DVFS (CPU regulator and CPU clocks) only in boards, to make sure only tested boards has DVFS enabled. This patchset : - moves the G12A DT to a common g12a-common dtsi - adds the G12A and G12B OPPs - enables DVFS on all supported boards Dependencies: - None Changes since RFT/RFC v3 at [3]: - Rebased on v5.3/fixes branch to take in order the last g12a.dtsi changes. - added Martin's review tags Changes since RFT/RFC v2 at [2]: - Rebased on linux-amlogic v5.3/dt64 Changes since RFT/RFC v1 at [1]: - Fixed G12B dtsi by adding back the sdio quirk - Fixed G12A dtsi unwanted sdio quirk removal [1] https://patchwork.kernel.org/cover/11006929/ [2] https://patchwork.kernel.org/cover/11017273/ [3] https://patchwork.kernel.org/cover/11025309/ Neil Armstrong (6): arm64: dts: move common G12A & G12B modes to meson-g12-common.dtsi arm64: dts: meson-g12-common: add pwm_a on GPIOE_2 pinmux arm64: dts: meson-g12a: add cpus OPP table arm64: dts: meson-g12a: enable DVFS on G12A boards arm64: dts: meson-g12b: add cpus OPP tables arm64: dts: meson-g12b-odroid-n2: enable DVFS .../boot/dts/amlogic/meson-g12-common.dtsi | 2417 ++++++++++++++++ .../boot/dts/amlogic/meson-g12a-sei510.dts | 55 + .../boot/dts/amlogic/meson-g12a-u200.dts | 54 + .../boot/dts/amlogic/meson-g12a-x96-max.dts | 52 + arch/arm64/boot/dts/amlogic/meson-g12a.dtsi | 2418 +---------------- .../boot/dts/amlogic/meson-g12b-odroid-n2.dts | 96 + arch/arm64/boot/dts/amlogic/meson-g12b.dtsi | 145 +- 7 files changed, 2856 insertions(+), 2381 deletions(-) create mode 100644 arch/arm64/boot/dts/amlogic/meson-g12-common.dtsi -- 2.22.0
