Also, for the isp0, we only need the ISP clock, ACLK and HCLK. In the future we'll need a pixel clock for RK3288 and RK3399, and a JPEG clock for RK3288. So with the goal to cleanup the dt-bindings and remove it from staging, simplify clock names to isp, aclk and hclk. For reference, this is the isp clock topology on RK3399: xin24m pll_npll npll clk_isp1 clk_isp0 pll_cpll cpll aclk_isp1 aclk_isp1_noc hclk_isp1 aclk_isp1_wrapper hclk_isp1_noc aclk_isp0 hclk_isp1_wrapper aclk_isp0_wrapper aclk_isp0_noc hclk_isp0 hclk_isp0_wrapper hclk_isp0_noc pclkin_isp1_wrapper Signed-off-by: Helen Koike --- Changes in V4: - update binding according to suggestion by Robin Murphy on https://patchwork.kernel.org/patch/11475007/ Changes in V3: - this is a new patch in the series --- .../bindings/media/rockchip-isp1.yaml | 30 +++++++++---------- drivers/staging/media/rkisp1/rkisp1-dev.c | 8 ++--- 2 files changed, 17 insertions(+), 21 deletions(-) diff --git a/drivers/staging/media/rkisp1/Documentation/devicetree/bindings/media/rockchip-isp1.yaml b/drivers/staging/media/rkisp1/Documentation/devicetree/bindings/media/rockchip-isp1.yaml index 4d111ef2e89c7..f10c53d008748 100644 --- a/drivers/staging/media/rkisp1/Documentation/devicetree/bindings/media/rockchip-isp1.yaml +++ b/drivers/staging/media/rkisp1/Documentation/devicetree/bindings/media/rockchip-isp1.yaml @@ -24,20 +24,20 @@ properties: maxItems: 1 clocks: - items: - - description: ISP clock - - description: ISP AXI clock clock - - description: ISP AXI clock wrapper clock - - description: ISP AHB clock clock - - description: ISP AHB wrapper clock + maxItems: 5 + minItems: 3 + description: + ISP clock + ISP AXI clock + ISP AHB clock clock-names: + maxItems: 5 + minItems: 3 items: - - const: clk_isp - - const: aclk_isp - - const: aclk_isp_wrap - - const: hclk_isp - - const: hclk_isp_wrap + - const: isp + - const: aclk + - const: hclk iommus: maxItems: 1 @@ -135,11 +135,9 @@ examples: reg = <0x0 0xff910000 0x0 0x4000>; interrupts = ; clocks = <&cru SCLK_ISP0>, - <&cru ACLK_ISP0>, <&cru ACLK_ISP0_WRAPPER>, - <&cru HCLK_ISP0>, <&cru HCLK_ISP0_WRAPPER>; - clock-names = "clk_isp", - "aclk_isp", "aclk_isp_wrap", - "hclk_isp", "hclk_isp_wrap"; + <&cru ACLK_ISP0_WRAPPER>, + <&cru HCLK_ISP0_WRAPPER>; + clock-names = "isp", "aclk", "hclk"; iommus = <&isp0_mmu>; phys = <&dphy>; phy-names = "dphy"; diff --git a/drivers/staging/media/rkisp1/rkisp1-dev.c b/drivers/staging/media/rkisp1/rkisp1-dev.c index f38801fea10d9..175ac25fe99fa 100644 --- a/drivers/staging/media/rkisp1/rkisp1-dev.c +++ b/drivers/staging/media/rkisp1/rkisp1-dev.c @@ -406,11 +406,9 @@ static irqreturn_t rkisp1_isr(int irq, void *ctx) } static const char * const rk3399_isp_clks[] = { - "clk_isp", - "aclk_isp", - "hclk_isp", - "aclk_isp_wrap", - "hclk_isp_wrap", + "isp", + "aclk", + "hclk", }; static const struct rkisp1_match_data rk3399_isp_clk_data = {
