From: Alexey Sheplyakov <asheplyakov@basealt.ru> To: devel-kernel@lists.altlinux.org Cc: nir@basealt.ru, jqt4@basealt.ru, rst@basealt.ru, sin@basealt.ru Subject: [d-kernel] [PATCH 05/31] dw-pcie: refuse to load on Baikal-M with recent firmware Date: Mon, 3 Oct 2022 18:02:01 +0400 Message-ID: <20221003140226.1064966-6-asheplyakov@basealt.ru> (raw) In-Reply-To: <20221003140226.1064966-1-asheplyakov@basealt.ru> Firmware from SDK-M 5.4 is incompatible with dw-pcie driver. Yet the DTB (passed to kernel by the firmware) claims otherwise. Hence refuse to load if device node is compatilbe with `baikal,bm1000-pcie` (earlier versions of Baikal-M firmware used a different compatible string).
