arm64: dts: imx8-ss-dma: fix adc lpcg indices
commit 81975080f14167610976e968e8016e92d836266f upstream.
adc0_lpcg: clock-controller@5ac80000 {
... Col1 Col2
clocks = <&clk IMX_SC_R_ADC_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 existing dts try to get.
Col2: actual index in lpcg driver.
adc0: adc@5a880000 {
clocks = <&adc0_lpcg 0>, <&adc0_lpcg 1>;
^^ ^^
clocks = <&adc0_lpcg IMX_LPCG_CLK_0>, <&adc0_lpcg IMX_LPCG_CLK_4>;
Arg0 is divided by 4 in lpcg driver. So adc get IMX_SC_PM_CLK_PER by
<&adc0_lpcg 0>, <&adc0_lpcg 1>. Although function can work, code logic is
wrong. Fix it by using correct indices.
