| |
Support regulators found on the e.g. KingFisher board for miniPCIe and add a 12v regulator while we are here.
Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> ---
Changes since RFC: * added 12V supply for completeness * use PCIe slot in the example instead of miniPCIe because that is what the Koelsch board offers (just without the regulators ;))
