I'd suggest moving the check to sun8i_ths_resource_init(), i.e. call sun8i_ths_calibrate() conditionally depending on whether calibrate callback is present. > kfree(caldata); > out: > @@ -628,6 +629,17 @@ static const struct ths_thermal_chip sun50i_h6_ths = { > .calc_temp = sun8i_ths_calc_temp, > }; > > +static const struct ths_thermal_chip sun50i_r329_ths = { > + .sensor_num = 1, > + .has_bus_clk_reset = true, > + .offset = 188744, > + .scale = 672, > + .temp_data_base = SUN50I_H6_THS_TEMP_DATA, > + .init = sun50i_h6_thermal_init, > + .irq_ack = sun50i_h6_irq_ack, > + .calc_temp = sun8i_ths_calc_temp, > +}; > + > static const struct of_device_id of_ths_match[] = { > { .compatible = "allwinner,sun8i-a83t-ths", .data = &sun8i_a83t_ths }, > { .compatible = "allwinner,sun8i-h3-ths", .data = &sun8i_h3_ths }, > @@ -636,6 +648,7 @@ static const struct of_device_id of_ths_match[] = { > { .compatible = "allwinner,sun50i-a100-ths", .data = &sun50i_a100_ths }, > { .compatible = "allwinner,sun50i-h5-ths", .data = &sun50i_h5_ths }, > { .compatible = "allwinner,sun50i-h6-ths", .data = &sun50i_h6_ths }, > + { .compatible = "allwinner,sun50i-r329-ths", .data = &sun50i_r329_ths }, > { /* sentinel */ }, > }; > MODULE_DEVICE_TABLE(of, of_ths_match); > -- > 2.35.1 >

Looking at the BSP smartx-r329-tina-for-jishu-community-v0.2, I see: ths_calib: calib@14 { reg = <0x14 4>; }; And the BSP driver (drivers/thermal/sunxi_thermal-ng.c) claims that R329 uses the same calibration method as for H616.

Maybe you are looking at an > older BSP? Yes. All these r329 work is done the last year during my internship at Sipeed. I will check the newer version of BSP and if okay I will add the calibrate routine in the next revision. > > Regards, > Samuel > > > > > Add its support to sun8i-thermal driver.
