X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=b8993bd786c1681ce0aa65b7a04159bf712c1e21;p=users%2Fwilly%2Fxarray.git

arm64: dts: qcom: qcs615-ride: Enable secondary USB controller on QCS615 Ride

Enable secondary USB controller on QCS615 Ride platform. The secondary
USB controller is made "host", as it is a Type-A port.

Secondary USB controller of QCS615 Ride has Type-A port exposed for
connecting peripheral. The VBUS to the peripheral is provided by
TPS2549IRTERQ1 regulator connected to the port. The regulator has an
enable pin controlled by PM8150. Model it as fixed regulator and keep it
Always-On at boot, since the regulator is GPIO controlled regulator.
