This is a note to let you know that I've just added the patch titled ARM: dts: ti: omap: Fix bandgap thermal cells addressing for omap3/4 to the 5.10-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: arm-dts-ti-omap-fix-bandgap-thermal-cells-addressing.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 173582c3069b5ce598a5ef0b9bad7559409e8c63 Author: Tony Lindgren <tony@xxxxxxxxxxx> Date: Mon Sep 11 07:07:38 2023 +0300 ARM: dts: ti: omap: Fix bandgap thermal cells addressing for omap3/4 [ Upstream commit 6469b2feade8fd82d224dd3734e146536f3e9f0e ] Fix "thermal_sys: cpu_thermal: Failed to read thermal-sensors cells: -2" error on boot for omap3/4. This is caused by wrong addressing in the dts for bandgap sensor for single sensor instances. Note that omap4-cpu-thermal.dtsi is shared across omap4/5 and dra7, so we can't just change the addressing in omap4-cpu-thermal.dtsi.
