Subject: ARM: dts: stm32: Repair SDMMC1 operation on AV96
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=45fa59b407163abbb553d7cd333b1302e878683a;p=u-boot.git

ARM: dts: stm32: Repair SDMMC1 operation on AV96

The SD uses different pinmux for the D123DIRline, use such a pinmux,
otherwise there is a pinmux collision on the AV96. Add missing SD
voltage regulator switch and enable SDR104 operation.
