If anyone has any objections, please let me know. ------------------ From: Frank Li commit 1d86c2b3946e69d6b0b93568d312aae6247847c0 upstream. lpcg's arg0 should use clock indices instead of index. pwm0_lpcg: clock-controller@5d400000 { ... // Col1 Col2 clocks = <&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>, // 0 0 <&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>, // 1 1 <&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>, // 2 4 <&lsio_bus_clk>, // 3 5 <&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>; // 4 6 clock-indices = , , , , ; }; Col1: index, which existing dts try to get. Col2: actual index in lpcg driver. pwm1 { .... clocks = <&pwm1_lpcg 4>, <&pwm1_lpcg 1>; ^^ ^^ should be: clocks = <&pwm1_lpcg IMX_LPCG_CLK_6>, <&pwm1_lpcg IMX_LPCG_CLK_1>; }; Arg0 is divided by 4 in lpcg driver, so index 0 and 1 will be get by pwm driver, which are same as IMX_LPCG_CLK_6 and IMX_LPCG_CLK_1. Even it can work, but code logic is wrong. Fixed it by use correct indices.
