Subject: [PATCH] arm64: dts: rockchip: Fix regulators and enable SATA on Radxa E25

Despite its name, the regulator vcc3v3_pcie30x1 has nothing to do with
pcie30x1. Instead, it supply power to VBAT1-5 on the M.2 KEY B port as
seen on page 8 of the schematic [1].

pcie30x1 is used for the mini PCIe slot, and as seen on page 9 the
vcc3v3_minipcie regulator is instead related to pcie30x1.

The M.2 KEY B port can be used for WWAN USB2 modules or SATA drives.

Use correct regulator vcc3v3_minipcie for pcie30x1 and enable sata1 node
to fix use of SATA drives on the M.2 slot.

Applied, thanks!

[1/2] arm64: dts: rockchip: Fix PCIe regulators on Radxa E25

[2/2] arm64: dts: rockchip: Enable SATA on Radxa E25
commit: 2bdfe84fbd57a4ed9fd65a67210442559ce078f0

As you can see, I've split them in two. Please check that I didn't
mess anything up. Having an "and" in the commit subject is always a
very strong indicator that a split is probably a good thing ;-)


Best regards,

Thanks, and they look fine. Should probably have split it in two from
the beginning, I will try to do better next time :-)
