[PATCH 0/6] arm: aspeed: Add eSPI support

From: Chia-Wei, Wang
Date: Wed Jan 06 2021 - 01:01:59 EST


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):
