Cover letter [PATCH v3 0/4] add support of SCPSYS power domain for MediaTek MT7622
From: Sean Wang <[email protected]>
Changes since v2:
- reduce code duplication of scpsys_probe across all SoCs
Changes since v1:
- rebase to Linux v4.13-rc1
There are four power domains on MediaTek MT7622 SoC which are respectively ETHSYS for Ethernet including extra embedded switch, HIF0SYS for PCI-E and SATA, HIF1SYS for USB and WBSYS for WIFI and Bluetooth.
Those functions could be selectively powered gated when the corresponding function is no longer to use in order to reach more minimal power dissipation through the patch series introduced here.
