charset="utf-8" From: Bartosz Golaszewski 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.
