Changes since v4 at [5]: - change yaml GPL - drop meson-eeclk.c patch, add probe function in each driver - add CLK_IS_CRITICAL for sys_clk clock, drop the flag for sys_a and sys_b - add new parm for pll, add protection for rst parm - drop flag for a1_fixed_pll - remove the same comment for fclk_div, add "refer to" - add critical flag for a1_sys_clk - remove rtc table - rename a1_dspa_en_dspa and a1_dspb_en_dspb - remove useless comment Changes since v3 at [3]: -fix reparenting orphan failed, it depends on jerome's patch [4] -fix changelist in v3 about reparenting orphan -remove the dts patch Changes since v2 at [2]: -add probe function for A1 -seperate the clock driver into two patch -change some clock flags and ops -add support for a1 PLL ops -add A1 clock node -fix reparenting orphan clock failed, registering xtal_fixpll and xtal_hifipll after the provider registration, it is not a best way. Changes since v1 at [1]: -place A1 config alphabetically -add actual reason for RO ops, CLK_IS_CRITICAL, CLK_IGNORE_UNUSED -separate the driver into two driver: peripheral and pll driver -delete CLK_IGNORE_UNUSED flag for pwm b/c/d/e/f clock, dsp clock -delete the change in Kconfig.platforms, address to Kevin alone -remove the useless comments -modify the meson pll driver to support A1 PLLs [1] https://lkml.kernel.org/r/1569411888-98116-1-git-send-email-jian.hu@amlogic.com [2] https://lkml.kernel.org/r/1571382865-41978-1-git-send-email-jian.hu@amlogic.com [3] https://lkml.kernel.org/r/20191129144605.182774-1-jian.hu@amlogic.com [4] https://lkml.kernel.org/r/20191203080805.104628-1-jbrunet@baylibre.com [5] https://lkml.kernel.org/r/20191206074052.15557-1-jian.hu@amlogic.com Jian Hu (5): dt-bindings: clock: meson: add A1 PLL clock controller bindings clk: meson: add support for A1 PLL clock ops clk: meson: a1: add support for Amlogic A1 PLL clock driver dt-bindings: clock: meson: add A1 peripheral clock controller bindings clk: meson: a1: add support for Amlogic A1 Peripheral clock driver .../bindings/clock/amlogic,a1-clkc.yaml | 67 + .../bindings/clock/amlogic,a1-pll-clkc.yaml | 54 + drivers/clk/meson/Kconfig | 18 + drivers/clk/meson/Makefile | 2 + drivers/clk/meson/a1-pll.c | 374 +++ drivers/clk/meson/a1-pll.h | 56 + drivers/clk/meson/a1.c | 2263 +++++++++++++++++ drivers/clk/meson/a1.h | 120 + drivers/clk/meson/clk-pll.c | 40 +- drivers/clk/meson/clk-pll.h | 2 + include/dt-bindings/clock/a1-clkc.h | 98 + include/dt-bindings/clock/a1-pll-clkc.h | 16 + 12 files changed, 3105 insertions(+), 5 deletions(-) create mode 100644 Documentation/devicetree/bindings/clock/amlogic,a1-clkc.yaml create mode 100644 Documentation/devicetree/bindings/clock/amlogic,a1-pll-clkc.yaml create mode 100644 drivers/clk/meson/a1-pll.c create mode 100644 drivers/clk/meson/a1-pll.h create mode 100644 drivers/clk/meson/a1.c create mode 100644 drivers/clk/meson/a1.h create mode 100644 include/dt-bindings/clock/a1-clkc.h create mode 100644 include/dt-bindings/clock/a1-pll-clkc.h
