Subject: [PATCH v2 0/2] riscv: dts: starfive: jh7110: increase eMMC bus
 speed

The deepcomputing fml13v01 eMMC memory slot is currently limited in
speed by the common definition, increase the common max-frequency
parameter and specifically increase the clock on the fml13v01 board.

This achieves a x2~ speed increase in seq read/write performance.

Changes in v2:
- Move max-frequency increase to jh7110-common
- Link to v1: https://lore.kernel.org/r/20250215-fml13v01_emmc_speed-v1-1-e3bd224ae0e8@hotmail.com
