Subject: [PATCH] arm64: dts: rockchip: Fix PCIe regulators 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.
