But it is still an issue with how your patchset in organized. I can't merge this until Kevin merges the patch above, which he can't merge until there is the clkc_ao support in axg, which is given by this series. 1# You should remove the axg part of the patch above. Kevin will be able to merge it w/o any dependencies. (BTW, the patch is broken for axg because 1) you did not include the dt-binding header for the clkc_ao in axg and 2) the clkc_ao does not exist at this stage) 2# I can then safely merge this series - w/o breaking gxbb and gxl. 3# Finally you'll have to make a DT change for the axg, enabling the clkc_ao and changes the uart clocks at the same time. > > > > Not merging it until we get to the bottom of this. > > > > > > > > > > > Qiufang Dai (1): > > > clk: meson-axg: Add AO Clock and Reset controller driver > > > > > > Yixun Lan (6): > > > clk: meson: migrate to devm_of_clk_add_hw_provider API > > > clk: meson: aoclk: refactor common code into dedicated file > > > dt-bindings: clock: axg-aoclkc: New binding for Meson-AXG SoC > > > dt-bindings: clock: reset: Add AXG AO Clock and Reset Bindings > > > clk: meson: drop CLK_SET_RATE_PARENT flag > > > clk: meson: drop CLK_IGNORE_UNUSED flag > > > > > > .../bindings/clock/amlogic,gxbb-aoclkc.txt | 1 + > > > drivers/clk/meson/Kconfig | 8 + > > > drivers/clk/meson/Makefile | 3 +- > > > drivers/clk/meson/axg-aoclk.c | 163 ++++++++++++++++++ > > > drivers/clk/meson/axg-aoclk.h | 29 ++++ > > > drivers/clk/meson/gxbb-aoclk.c | 95 ++++------ > > > drivers/clk/meson/gxbb-aoclk.h | 5 + > > > drivers/clk/meson/meson-aoclk.c | 81 +++++++++ > > > drivers/clk/meson/meson-aoclk.h | 34 ++++ > > > include/dt-bindings/clock/axg-aoclkc.h | 26 +++ > > > include/dt-bindings/reset/axg-aoclkc.h | 20 +++ > > > 11 files changed, 401 insertions(+), 64 deletions(-) > > > create mode 100644 drivers/clk/meson/axg-aoclk.c > > > create mode 100644 drivers/clk/meson/axg-aoclk.h > > > create mode 100644 drivers/clk/meson/meson-aoclk.c > > > create mode 100644 drivers/clk/meson/meson-aoclk.h > > > create mode 100644 include/dt-bindings/clock/axg-aoclkc.h > > > create mode 100644 include/dt-bindings/reset/axg-aoclkc.h > > > > > > > . > > > > -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
