I applied the whole series locally, it applies fine on 6.19 but I didn't
check linux-next; and tested it on Exynos850 E850-96 board with the
following DT node:
tmuctrl_0: tmu@10070000 {
compatible = "samsung,exynos850-tmu";
reg = <0x10070000 0x800>;
interrupts = <GIC_SPI 226 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&cmu_peri CLK_GOUT_BUSIF_TMU_PCLK>;
clock-names = "tmu_apbif";
#thermal-sensor-cells = <0>;
};
and thermal zones as you mentioned way back. It works just fine.
Temp goes up to 48 C with a loaded CPUs and settles at 36-37C when idle.
So for the whole series:
Tested-by: Alexey Klimov <alexey.klimov@xxxxxxxxxx>
However, do you have plans to update it or re-submit?
Or any other plans working on it?
Thank you!
Best regards,
Alexey
