[U-Boot] [PATCH 3/3] imx: imx6ul_evk: Enable DM driver for iMX6UL EVK u-boot
Ye Li

Thu Jun 28 03:23:17 UTC 2018
Convert the codes and configurations to enable DM drivers in u-boot for
modules: i2c, PMIC, regulator, USB, Ethernet, SD/MMC, GPIO and QSPI
This patch does not change SPL, so it still uses non-DM driver for
UART, GPIO and SD/MMC.
