Subject: [PATCH v2 01/12] dt-bindings: PCI: Add Broadcom STB 7712 SOC, update maintainer
Date: Wed,  3 Jul 2024 14:02:45 -0400	[thread overview]
Message-ID: <20240703180300.42959-2-james.quinlan@broadcom.com> (raw)
In-Reply-To: <20240703180300.42959-1-james.quinlan@broadcom.com>

[-- Attachment #1: Type: text/plain, Size: 3255 bytes --]

- Update maintainer; Nicolas hasn't been active and it
  makes more sense to have a Broadcom maintainer
- Add a driver compatible string for the new STB SOC 7712
- Add two new resets for the 7712: "bridge", for the
  the bridge between the PCIe core and the memory bus;
  "swinit", the PCIe core reset.
- Order the compatible strings alphabetically
- Restructure the reset controllers so that the definitions
  appear first before any rules that govern them.
