Subject: [PATCH 0/5] Add Aspeed G7 sgpio support
Date: Sat, 17 Jan 2026 19:17:07 +0800 [thread overview]
Message-ID: <20260117-upstream_sgpio-v1-0-850ef3ffb680@aspeedtech.com> (raw)
The Aspeed 7th generation SoC features two SGPIO master controllers: both
with 256 serial inputs and outputs. The main difference from the previous
generation is that the control logic has been updated to support
per-pin control, allowing each pin to have its own 32-bit register for
configuring value, interrupt type, and more.
This patch serial also add low-level operations (llops) to abstract the
register access for SGPIO registers making it easier to extend the driver
to support different hardware register layouts.
