Subject: [PATCH v2 0/4] Add Aspeed AST2700 uhci support
Date: Wed, 17 Sep 2025 10:19:22 +0800 [thread overview]
Message-ID: <20250917021926.3692137-1-ryan_chen@aspeedtech.com> (raw)
This patch series adds support for the UHCI controller found on the
Aspeed AST2700 SoC.
Compared to earlier SoCs (AST2400/2500/2600), AST2700 UHCI:
- requires a reset line to be deasserted before use
- supports 64-bit DMA addressing
This series updates the bindings and platform driver accordingly.
v2:
- usb-uhci.yaml
- add required resets for aspeed,ast2700-uhci
- uhci-platform.c
- change the err_clk before err_reset.
