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.
