These seem to fall into three categories: - 150us for 8250 and earlier - 400us for 8350 and friends - 1000us for >=8450 Make some housecleaning changes and describe these delays in preparation to moving this data out of the venus driver. Signed-off-by: Konrad Dybcio --- Changes in v2: - Wrap the function parameters in patch 2 - Better describe the sources of reset delay values - Pick up tags, rebase (with no changes) - Link to v1: https://lore.kernel.org/r/20240105-topic-venus_reset-v1-0-981c7a624855@linaro.org --- Konrad Dybcio (18): clk: qcom: reset: Increase max reset delay clk: qcom: reset: Commonize the de/assert functions clk: qcom: reset: Ensure write completion on reset de/assertion clk: qcom: gcc-sa8775p: Set delay for Venus CLK resets clk: qcom: gcc-sc8180x: Set delay for Venus CLK resets clk: qcom: gcc-sc8280xp: Set delay for Venus CLK resets clk: qcom: gcc-sm4450: Set delay for Venus CLK resets clk: qcom: gcc-sm7150: Set delay for Venus CLK resets clk: qcom: gcc-sm8250: Set delay for Venus CLK resets clk: qcom: gcc-sm8350: Set delay for Venus CLK resets clk: qcom: gcc-sm8450: Set delay for Venus CLK resets clk: qcom: gcc-sm8550: Set delay for Venus CLK resets clk: qcom: gcc-sm8650: Set delay for Venus CLK resets clk: qcom: videocc-sm8150: Set delay for Venus CLK resets clk: qcom: videocc-sm8250: Set delay for Venus CLK resets clk: qcom: videocc-sm8350: Set delay for Venus CLK resets clk: qcom: videocc-sm8450: Set delay for Venus CLK resets clk: qcom: videocc-sm8550: Set delay for Venus CLK resets drivers/clk/qcom/gcc-sa8775p.c | 4 ++-- drivers/clk/qcom/gcc-sc8180x.c | 6 +++--- drivers/clk/qcom/gcc-sc8280xp.c | 4 ++-- drivers/clk/qcom/gcc-sm4450.c | 4 ++-- drivers/clk/qcom/gcc-sm7150.c | 2 +- drivers/clk/qcom/gcc-sm8250.c | 4 ++-- drivers/clk/qcom/gcc-sm8350.c | 4 ++-- drivers/clk/qcom/gcc-sm8450.c | 4 ++-- drivers/clk/qcom/gcc-sm8550.c | 4 ++-- drivers/clk/qcom/gcc-sm8650.c | 4 ++-- drivers/clk/qcom/reset.c | 27 ++++++++++++++------------- drivers/clk/qcom/reset.h | 2 +- drivers/clk/qcom/videocc-sm8150.c | 2 +- drivers/clk/qcom/videocc-sm8250.c | 4 ++-- drivers/clk/qcom/videocc-sm8350.c | 4 ++-- drivers/clk/qcom/videocc-sm8450.c | 4 ++-- drivers/clk/qcom/videocc-sm8550.c | 4 ++-- 17 files changed, 44 insertions(+), 43 deletions(-) --- base-commit: ac139fc7db67968e5061715508b5fc4aa7c40c56 change-id: 20240105-topic-venus_reset-b5461bf1a087 Best regards,
