Subject: mmc: fsl_esdhc_imx: Enable AHB/IPG clk with clk bulk API
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=76332fae769acbba49751827ce126b0cb1014b48;p=u-boot.git

mmc: fsl_esdhc_imx: Enable AHB/IPG clk with clk bulk API

With partition reset supported for i.MX8QM/QXP/95 and etc, when linux
mmc runtime suspended, the mmc clks are gated off. While at same time
system controller reset Cortex-A cores because of various reasons(
WDOG timeout and etc), with SPL run again, only enable PER clk is not
enough, also need to enable AHB/IPG clk, here use clk bulk API to enable
all the clocks.
