[PATCH 4/7] arm64: dts: imx8-ss-dma: fix pwm lpcg indices

[Frank Li <Frank.Li@nxp.com>]

adma_pwm_lpcg: clock-controller@5a590000 {
	...							 col1 col2
	clocks = <&clk IMX_SC_R_LCD_0_PWM_0 IMX_SC_PM_CLK_PER>,// 0   0
		 <&dma_ipg_clk>;                               // 1   4
	clock-indices = <IMX_LPCG_CLK_0>, <IMX_LPCG_CLK_4>;
        ...
};

Col1: index, which exited dts try to get.
Col2: actual index in lpcg driver.

adma_pwm: pwm@5a190000 {
	...
	clocks = <&adma_pwm_lpcg 1>, <&adma_pwm_lpcg 0>;
				 ^^		     ^^
Should be
	clocks = <&adma_pwm_lpcg IMX_LPCG_CLK_4>,
		 <&adma_pwm_lpcg IMX_LPCG_CLK_0>;
};

Arg0 will be divided by 4 in lcpg driver, so pwm will get IMX_SC_PM_CLK_PER
by <&adma_pwm_lpcg 1>, <&adma_pwm_lpcg 0>. Although function can work, code
logic is wrong. Fix it by use correct indices.
