Subject: mediatek: mt7622: provide power on mPCIe in SATA mode
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0d9aae10e4f8821bfe583eb95e1c53aeba34bedb;p=openwrt%2Fstaging%2Fblogic.git

mediatek: mt7622: provide power on mPCIe in SATA mode

User reported that R64 doesn't provide power to the mPCIe slot in case
the PCIe port is disabled as it is when selecting the SATA
configuration. As users may still want to use USB-connected mPCIe
modules in CN8 slot.
