Subject: [PATCH] arm64: dts: qcom: ipq9574: Fix USB vdd info
|
|
|
|
USB phys in ipq9574 use the 'L5' regulator. The commit ec4f047679d5
|
|
("arm64: dts: qcom: ipq9574: Enable USB") incorrectly specified it as
|
|
'L2'. Because of this when the phy module turns off/on its regulators,
|
|
the wrong regulator is turned off/on resulting in 2 issues, namely the
|
|
correct regulator related to the USB phy is not turned off/on and the
|
|
module powered by the incorrect regulator is affected.
|
|
|
|
