Subject: [PATCH v3 0/4] Add Aspeed AST2700 uhci support
Date: Fri, 19 Sep 2025 10:57:08 +0800 [thread overview]
Message-ID: <20250919025712.719246-1-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.
v3:
- uhci-platform.c
- add reset_control_assert in uhci_hcd_platform_remove.
v2:
- usb-uhci.yaml
- add required resets for aspeed,ast2700-uhci
- uhci-platform.c
- change the err_clk before err_reset.
