ARM: dts: imx7-colibri: Fix frequency for eMMC
eMMC, used in Colibri iMX7D eMMC modules, supports 200Mhz mode with vccq=1.8v. Remove the max-frequency limit, it increases the performance significantly: == before fix ==== root@colibri-imx7-emmc:~# hdparm -t /dev/mmcblk1 /dev/mmcblk1: Timing buffered disk reads: `^H252 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 ================== Related-to: ELB-1442 Fixes: f928a4a377e4 ("ARM: dts: imx7: add Toradex Colibri iMX7D 1GB (eMMC) support") Signed-off-by: Oleksandr Suvorov <oleksandr.suvorov@toradex.com>
