This subsystem is designed to control power to devices that share complex resources and/or require specific power sequences to be run during power-up. If unsure, say no. if POWER_SEQUENCING config POWER_SEQUENCING_QCOM_WCN tristate "Qualcomm WCN family PMU driver" default m if ARCH_QCOM depends on OF || COMPILE_TEST help Say Y here to enable the power sequencing driver for Qualcomm WCN Bluetooth/WLAN chipsets. Typically, a package from the Qualcomm WCN family contains the BT and WLAN modules whose power is controlled by the PMU module. As the former two share the power-up sequence which is executed by the PMU, this driver is needed for correct power control or else we'd risk not respecting the required delays between enabling Bluetooth and WLAN. config POWER_SEQUENCING_TH1520_GPU tristate "T-HEAD TH1520 GPU power sequencing driver" depends on (ARCH_THEAD && AUXILIARY_BUS) || COMPILE_TEST help Say Y here to enable the power sequencing driver for the TH1520 SoC GPU. This driver handles the complex clock and reset sequence required to power on the Imagination BXM GPU on this platform. endif
