This series adds support for the clock and reset controller in the Nuvoton WPCM450 SoC. This means that the clock rates for peripherals will be calculated automatically based on the clock tree as it was preconfigured by the bootloader. The 24 MHz dummy clock, that is currently in the devicetree, is no longer needed. Somewhat unfortunately, this also means that there is a breaking change once the devicetree starts relying on the clock driver, but I find it acceptable in this case, because WPCM450 is still at a somewhat early stage. v6: - Dropped all patches except the clock binding and the clock driver, because they have mostly been merged - Minor correction to how RESET_SIMPLE is selected v5: - Dropped patch 2 (watchdog: npcm: Enable clock if provided), which was since merged upstream - Added patch 2 (clocksource: timer-npcm7xx: Enable timer 1 clock before use) again, because I wasn't able to find it in linux-next - Switched the driver to using struct clk_parent_data - Rebased on 6.1-rc3 v4: - Leave WDT clock running during after restart handler - Fix reset controller initialization - Dropped patch 2/7 (clocksource: timer-npcm7xx: Enable timer 1 clock before use), as it was applied by Daniel Lezcano v3: - https://lore.kernel.org/lkml/20220508194333.2170161-1-j.neuschaefer@xxxxxxx/ - Changed "refclk" string to "ref" - Fixed some dead code in the driver - Added clk_prepare_enable call to the watchdog restart handler - Added a few review tags v2: - https://lore.kernel.org/lkml/20220429172030.398011-1-j.neuschaefer@xxxxxxx/ - various small improvements v1: - https://lore.kernel.org/lkml/20220422183012.444674-1-j.neuschaefer@xxxxxxx/ Jonathan Neuschäfer (2): dt-bindings: clock: Add Nuvoton WPCM450 clock/reset controller clk: wpcm450: Add Nuvoton WPCM450 clock/reset controller driver .../bindings/clock/nuvoton,wpcm450-clk.yaml | 66 +++ drivers/clk/Makefile | 1 + drivers/clk/clk-wpcm450.c | 375 ++++++++++++++++++ drivers/reset/Kconfig | 2 +- .../dt-bindings/clock/nuvoton,wpcm450-clk.h | 67 ++++ 5 files changed, 510 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/clock/nuvoton,wpcm450-clk.yaml create mode 100644 drivers/clk/clk-wpcm450.c create mode 100644 include/dt-bindings/clock/nuvoton,wpcm450-clk.h -- 2.39.2
