X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b952f96a57e6fb4528c1d6be19e941c3322f9905;p=linux.git

dt-bindings: PCI: rcar-pci-host: Add optional regulators

Support regulators found on the KingFisher board for miniPCIe (1.5 and
3.3v). For completeness, describe a 12v regulator while we are here.
