Subject: ARM: dts: imx7[d]-mba7: hog Mini PCIe signals
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=90ca55dc1382887f9e63460dca092b9b7a79db03;p=linux.git

ARM: dts: imx7[d]-mba7: hog Mini PCIe signals

PCIE_DIS & PCIE_RST (correctly named W_DISABLE# & PERST#) affect USB
devices as well. So hog them to make USB devices attached to Mini PCIe
connector available, despite PCIe being disabled.
Supply voltages are enabled unconditionally.
