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.

Ryan Chen (4):
  dt-bindings: usb: uhci: Add reset property
  usb: uhci: Add reset control support
  dt-bindings: usb: uhci: Add Aspeed AST2700 compatible
  usb: uhci: Add Aspeed AST2700 support
