The following patches add dt support for MMC/SD on TI's j7200-evm.
Currently, eMMC support upto HS200 speed and SD card supports upto high
speed speed mode.
These patches depend on:
Lokesh's initial support series
https://patchwork.kernel.org/cover/11740039/
Vignesh's I2C support series
https://lore.kernel.org/patchwork/cover/1282152/
Vignesh's Hyperflash series
https://lore.kernel.org/patchwork/cover/1285326/

2.17.1
Add support for MMC/SD controller nodes present on TI's j7200 SoCs.
There are two nodes:
1. sdhci0 (8 bit bus width, 200 MHz, HS200, 200 MBps)
2. sdhci1 (4 bit bus width, 50 MHz, HS, 25 MBps)
