[PATCH v2 0/5] arm: aspeed: Add eSPI support

[Chia-Wei Wang]

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.

v2:
 - remove irqchip implementation
 - merge per-channel drivers into single one to avoid the racing issue
   among eSPI handshake process and driver probing.
