arm64: dts: imx8-ss-dma: fix spi lpcg indices
commit f72b544a514c07d34a0d9d5380f5905b3731e647 upstream.
spi0_lpcg: clock-controller@5a400000 {
... Col0 Col1
clocks = <&clk IMX_SC_R_SPI_0 IMX_SC_PM_CLK_PER>,// 0 1
<&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.
lpspi0: spi@5a000000 {
...
clocks = <&spi0_lpcg 0>, <&spi0_lpcg 1>;
^ ^
Should be:
clocks = <&spi0_lpcg IMX_LPCG_CLK_0>, <&spi0_lpcg IMX_LPCG_CLK_4>;
};
Arg0 is divided by 4 in lpcg driver. <&spi0_lpcg 0> and <&spi0_lpcg 1> are
IMX_SC_PM_CLK_PER. Although code can work, code logic is wrong. It should
use IMX_LPCG_CLK_0 and IMX_LPCG_CLK_4 for lpcg arg0.
