Subject: [PATCH v6 5/6] arm64: dts: qcom: sc8280xp-x13s: model the PMU of
the on-board wcn6855
From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>
Add a node for the PMU of the WCN6855 and rework the inputs of the wifi
and bluetooth nodes to consume the PMU's outputs.
With this we can drop the regulator-always-on properties from vreg_s11b
and vreg_s12b as they will now be enabled by the power sequencing
driver.
