[PATCH 0/3] arm64: dts: renesas: Add max-frequency to SDHI nodes
From: Biju

From: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>
Add the max-frequency property set to 133333333 Hz (133.33 MHz) to both
SDHI0 and SDHI1 MMC controller nodes in the RZ/G2{L,LC,UL}/RZ/V2L
device tree.
This change results in approximately 33% performance improvement as
it sets the SD clk to 100 MHz instead of the max 133 MHz.
