Board：imx6ul When UBOOT resets LCDIF block, what is the reason for clkgate setting failure

Hi 我的钱去玩儿群无

LCD clocks are enabled in CCM_CCGR2 register described in

sect.18.6.25 CCM Clock Gating Register 2 (CCM_CCGR2)

i.MX 6UltraLite Applications Processor Reference Manual

clocks can be enabled in dcd header:

imximage.cfg\mx6ullevk\freescale\board - uboot-imx - i.MX U-Boot

Best regards
igor
