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.

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.
