This is a note to let you know that I've just added the patch titled arm64: dts: rockchip: Remove #cooling-cells from fan on Theobroma lion to the 6.6-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: arm64-dts-rockchip-remove-cooling-cells-from-fan-on-.patch and it can be found in the queue-6.6 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 51d352a130300837e7fa6a15ef856fec080974e0 Author: Heiko Stuebner <heiko@xxxxxxxxx> Date: Tue Oct 8 22:39:32 2024 +0200 arm64: dts: rockchip: Remove #cooling-cells from fan on Theobroma lion [ Upstream commit 5ed96580568c4f79a0aff11a67f10b3e9229ba86 ] All Theobroma boards use a ti,amc6821 as fan controller. It normally runs in an automatically controlled way and while it may be possible to use it as part of a dt-based thermal management, this is not yet specified in the binding, nor implemented in any kernel. Newer boards already don't contain that #cooling-cells property, but older ones do. So remove them for now, they can be re-added if thermal integration gets implemented in the future. There are two further occurences in v6.12-rc in px30-ringneck and rk3399-puma, but those already get removed by the i2c-mux conversion scheduled for 6.13 . As the undocumented property is in the kernel so long, I opted for not causing extra merge conflicts between 6.12 and 6.13 Fixes: d99a02bcfa81 ("arm64: dts: rockchip: add RK3368-uQ7 (Lion) SoM") Cc: Quentin Schulz <quentin.schulz@xxxxxxxxxxxxxxxxxxxxx> Cc: Klaus Goger <klaus.goger@xxxxxxxxxxxxxxxxxxxxx> Reviewed-by: Quentin Schulz <quentin.schulz@xxxxxxxxx> Reviewed-by: Dragan Simic <dsimic@xxxxxxxxxxx> Signed-off-by: Heiko Stuebner <heiko@xxxxxxxxx> Link: https://lore.kernel.org/r/20241008203940.2573684-7-heiko@xxxxxxxxx Signed-off-by: Heiko Stuebner <heiko@xxxxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> diff --git a/arch/arm64/boot/dts/rockchip/rk3368-lion.dtsi b/arch/arm64/boot/dts/rockchip/rk3368-lion.dtsi index 5753e57fd7161..e8859cfd2d39b 100644 --- a/arch/arm64/boot/dts/rockchip/rk3368-lion.dtsi +++ b/arch/arm64/boot/dts/rockchip/rk3368-lion.dtsi @@ -60,7 +60,6 @@ i2c_lvds_blc: i2c@0 { fan: fan@18 { compatible = "ti,amc6821"; reg = <0x18>; - #cooling-cells = <2>; }; rtc_twi: rtc@6f {
