This patch series add the driver support for the eSPI controller of Aspeed 5/6th generation SoCs. This controller is a slave device communicating with a master over Enhanced Serial Peripheral Interface (eSPI). It supports all of the 4 eSPI channels, namely peripheral, virtual wire, out-of-band, and flash, and operates at max frequency of 66MHz. v5: - unconditionally set VW GPIO to software mode as suggested by Jeremy - add missing DTS node for Aspeed G5 SoCs v4: - fix dt-bindgins error with patternProperties - fix data type warning for ARM64 compilation - replace header based implementation with .c files - add more description for the ioctl interface v3: - remove the redundant patch "clk: aspeed: Add eSPI reset bit" - fix missing header inclusion reported by test bot - fix dt-bindings error reported by yamllint v2: - remove irqchip implementation - merge per-channel drivers into single one to avoid the racing issue among eSPI handshake process and driver probing.
