This patch series add the driver support for the eSPI controller
of Aspeed 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.

Chia-Wei, Wang (6):
  dt-bindings: aspeed: Add eSPI controller
  MAINTAINER: Add ASPEED eSPI driver entry
  clk: ast2600: Add eSPI reset bit
  irqchip/aspeed: Add Aspeed eSPI interrupt controller
  soc: aspeed: Add eSPI driver
  ARM: dts: aspeed: Add AST2600 eSPI nodes
