arm64: dts: tegra186: Assign clocks for sdmmc1 and sdmmc4 (98a2494f) · Commits · 戴 / test

Configure sdmmc4 parent clock to pllc4 and sdmmc1 to pllp_out0 by setting the assigned-clocks device tree properties. pllc4 offer better jitter performance and should be used with higher speed modes like HS200 and HS400. Signed-off-by:
