Subject: [PATCH v4 2/2] ARM: dts: aspeed: add 'resets' to video node
Date: Fri, 5 Jun 2026 13:52:43 +0800 [thread overview]
Message-ID: <20260605055712.118501-3-haiyuewa@163.com> (raw)
In-Reply-To: <20260605055712.118501-1-haiyuewa@163.com>
The aspeed video (be compatible for ast2400, ast2500, ast2600) now needs
the reset DTS handle specified, otherwise it will fail to load:
[ 4.809494] aspeed-video 1e700000.video: irq 57
[ 4.809977] aspeed-video 1e700000.video: Unable to get reset
[ 4.810341] aspeed-video 1e700000.video: probe with driver aspeed-video failed with error -2
Fixes: e83f8dd668ea ("media: aspeed: Fix dram hang at res-change")
