When the clock have a "CGU_CLK_MUX" has only one bit, the 3/4 bits of parents do not need to be filled with -1. Clean up these unnecessary -1 from all the xxxx-cgu.c files. 2.Reformat code, add missing blank lines, remove unnecessary commas and tabs, and align code. Signed-off-by: 周琰杰 (Zhou Yanjie) --- Notes: v1->v2: Remove unnecessary -1 and commas. v2->v3: No change. v3->v4: 1.The -1 used for placeholders on the unused bits of the parents in the custom clock should not be removed. 2.Move "JZ4780_CLK_CORE1" from the "Gate-only clocks" class to the "Custom (SoC-specific)" class, because it belongs to the custom clock. v4->v5: No change. v5->v6: No change. drivers/clk/ingenic/jz4725b-cgu.c | 49 ++++++++------- drivers/clk/ingenic/jz4740-cgu.c | 49 ++++++++------- drivers/clk/ingenic/jz4760-cgu.c | 106 ++++++++++++++++++++----------- drivers/clk/ingenic/jz4770-cgu.c | 83 ++++++++++++------------ drivers/clk/ingenic/jz4780-cgu.c | 128 +++++++++++++++++++------------------- drivers/clk/ingenic/x1000-cgu.c | 117 +++++++++++++++++----------------- drivers/clk/ingenic/x1830-cgu.c | 113 ++++++++++++++++----------------- 7 files changed, 343 insertions(+), 302 deletions(-) diff --git a/drivers/clk/ingenic/jz4725b-cgu.c b/drivers/clk/ingenic/jz4725b-cgu.c index 5154b0c..77d6979 100644 --- a/drivers/clk/ingenic/jz4725b-cgu.c +++ b/drivers/clk/ingenic/jz4725b-cgu.c @@ -17,7 +17,7 @@ /* CGU register offsets */ #define CGU_REG_CPCCR 0x00 -#define CGU_REG_LCR 0x04 +#define CGU_REG_LCR 0x04 #define CGU_REG_CPPCR 0x10 #define CGU_REG_CLKGR 0x20 #define CGU_REG_OPCR 0x24 @@ -28,7 +28,7 @@ #define CGU_REG_CIMCDR 0x78 /* bits within the LCR register */ -#define LCR_SLEEP BIT(0) +#define LCR_SLEEP BIT(0) static struct ingenic_cgu *cgu; @@ -78,7 +78,7 @@ static const struct ingenic_cgu_clk_info jz4725b_cgu_clocks[] = { [JZ4725B_CLK_PLL_HALF] = { "pll half", CGU_CLK_DIV, -
