Parth Pancholi	c01d6934a7	arm: mach-k3: am62: fixup thermal cooling device cpus ... AM62x devices now support CPU throttling based on thermal alerts with a Linux commit 10e7bfd8114c ("arm64: dts: ti: k3-am62: Enable CPU freq throttling on thermal alert"). However, this functionality does not work correctly across all variants of the AM62x SoCs which have different numbers of Cortex-A CPU cores: AM62x1 (1 core), AM62x2 (2 cores), and AM62x4 (4 cores). On single-core and dual-core AM62x devices, the following error is observed in the Linux kernel: OF: /thermal-zones/main0-thermal/cooling-maps/map0: could not find phandle 94 OF: /thermal-zones/main1-thermal/cooling-maps/map0: could not find phandle 94 This commit adds a fixup to dynamically adjust the cooling-device nodes in the thermal zones based on the actual number of CPU cores available. This resolves the issue of CPU throttling not working correctly on single-core and dual-core AM62x devices, while maintaining the functionality for AM62x quad-core devices. A similar approach is implemented for example on i.MX8MM SoC. Signed-off-by: Parth Pancholi <parth.pancholi@toradex.com>	2024-10-17 15:01:24 -06:00
