Please find below a changelog for the reset sub-series: v6: - split the reset part into sub-series, add the Reviewed-by from Philipp v5: - Moved the reset de-assertion from the reset driver to the clock driver. The reset is now only de-asserted once the sys and core clocks have been enabled - Added and exported the GPU_CLKGEN reset, allowing the clock driver to reset the GPU clock circuit v4: - reverted reset-cells configuration to single cell as in v2 - maintained reset definitions in device tree bindings while deferring implementation of watchdog timer (WDT) reset functionality v3: - refactored reset driver to use zero cells v2: - developed a reset controller driver for the TH1520 to manage reset sequences - added new dt-bindings for reset > > Michal Wilczynski (2): > dt-bindings: reset: Add T-HEAD TH1520 SoC Reset Controller > reset: thead: Add TH1520 reset controller driver > > .../bindings/reset/thead,th1520-reset.yaml | 44 ++++++ > MAINTAINERS | 3 + > drivers/reset/Kconfig | 10 ++ > drivers/reset/Makefile | 1 + > drivers/reset/reset-th1520.c | 135 ++++++++++++++++++ > .../dt-bindings/reset/thead,th1520-reset.h | 16 +++ > 6 files changed, 209 insertions(+) > create mode 100644 Documentation/devicetree/bindings/reset/thead,th1520-reset.yaml > create mode 100644 drivers/reset/reset-th1520.c > create mode 100644 include/dt-bindings/reset/thead,th1520-reset.h >
