ARM: dts: imx7-colibri: Fix frequency for sd/mmc
SD/MMC on Colibri iMX7S/D modules successfully support 200Mhz frequency in HS200 mode. Removing the unnecessary max-frequency limit significantly increases the performance: == before fix ==== root@colibri-imx7-emmc:~# hdparm -t /dev/mmcblk0 /dev/mmcblk0: Timing buffered disk reads: 252 MB in 3.02 seconds = 83.54 MB/sec ================== === after fix ==== root@colibri-imx7-emmc:~# hdparm -t /dev/mmcblk0 /dev/mmcblk0: Timing buffered disk reads: 408 MB in 3.00 seconds = 135.94 MB/sec ================== Fixes: f928a4a377e4 ("ARM: dts: imx7: add Toradex Colibri iMX7D 1GB (eMMC) support") Signed-off-by: Oleksandr Suvorov <oleksandr.suvorov@toradex.com> Reviewed-by: Fabio Estevam <festevam@gmail.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
