This patchset : - introduces needed core and meson clk changes - adds support for the G12B second cluster clock measurer ids - protects clock measurer from cooncurent measures - adds the clock notifiers - moves the G12A DT to a common g12a-common dtsi - adds the G12A and G12B OPPs - enables DVFS on all supported boards Dependencies: - PWM AO input order fix at [1] - PWM enhancements from Martin at [2] Changes since RFT/RFC v1 at [3]: - Added EXPORT_SYMBOL_GPL() to clk_hw_set_parent - Added missing static to g12b_cpub_clk_mux0_div_ops and g12a_cpu_clk_mux_nb - Simplified g12a_cpu_clk_mux_notifier_cb() without switch/case - Fixed typo in "this the current path" in g12a.c - Fixed G12B dtsi by adding back the sdio quirk - Fixed G12A dtsi unwanted sdio quirk removal - Fixed various checkpatch errors [1] https://patchwork.kernel.org/patch/11006835/ [2] https://patchwork.kernel.org/patch/11006835/ [3] https://patchwork.kernel.org/cover/11006929/ Neil Armstrong (14): pinctrl: meson-g12a: add pwm_a on GPIOE_2 pinmux clk: core: introduce clk_hw_set_parent() clk: meson: regmap: export regmap_div ops functions clk: meson: eeclk: add setup callback soc: amlogic: meson-clk-measure: protect measure with a mutex soc: amlogic: meson-clk-measure: add G12B second cluster cpu clk clk: meson: g12a: add notifiers to handle cpu clock change clk: meson: g12a: expose CPUB clock ID for G12B 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 | 2464 ++++++++++++++++ .../boot/dts/amlogic/meson-g12a-sei510.dts | 55 + .../boot/dts/amlogic/meson-g12a-u200.dts | 55 + .../boot/dts/amlogic/meson-g12a-x96-max.dts | 52 + arch/arm64/boot/dts/amlogic/meson-g12a.dtsi | 2502 +---------------- .../boot/dts/amlogic/meson-g12b-odroid-n2.dts | 96 + arch/arm64/boot/dts/amlogic/meson-g12b.dtsi | 145 +- drivers/clk/clk.c | 6 + drivers/clk/meson/clk-regmap.c | 10 +- drivers/clk/meson/clk-regmap.h | 5 + drivers/clk/meson/g12a.c | 500 +++- drivers/clk/meson/meson-eeclk.c | 6 + drivers/clk/meson/meson-eeclk.h | 1 + drivers/pinctrl/meson/pinctrl-meson-g12a.c | 9 + drivers/soc/amlogic/meson-clk-measure.c | 14 +- include/dt-bindings/clock/g12a-clkc.h | 1 + include/linux/clk-provider.h | 1 + 17 files changed, 3439 insertions(+), 2483 deletions(-) create mode 100644 arch/arm64/boot/dts/amlogic/meson-g12-common.dtsi -- 2.21.0
