Subject: [PATCH v2 0/5] arm: aspeed: Add eSPI support
Date: Thu, 19 Aug 2021 16:00:35 +0800 [thread overview]
Message-ID: <20210819080040.31242-1-chiawei_wang@aspeedtech.com> (raw)
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.
