From cb68a8580e2086fad38597af4c60d39de8df0cde Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sun, 15 Nov 2020 20:06:58 +0100 Subject: [PATCH] thermal: amlogic: Add hwmon support Many monitoring tools read the CPU temperature using the hwmon interface. Expose the thermal sensors on Amlogic boards as hwmon devices. Without this lm_sensors' "sensors" tool does not find any temperature sensors. Now it prints: cpu_thermal-virtual-0 Adapter: Virtual device temp1: +44.7 C (crit = +110.0 C) ddr_thermal-virtual-0 Adapter: Virtual device temp1: +45.9 C (crit = +110.0 C) Signed-off-by: Martin Blumenstingl Reviewed-by: Neil Armstrong Signed-off-by: Daniel Lezcano Link: https://lore.kernel.org/r/20201115190658.631578-1-martin.blumenstingl@googlemail.com --- drivers/thermal/amlogic_thermal.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/drivers/thermal/amlogic_thermal.c b/drivers/thermal/amlogic_thermal.c index ccb1fe18e9931..dffe3ba8c7c44 100644 --- a/drivers/thermal/amlogic_thermal.c +++ b/drivers/thermal/amlogic_thermal.c @@ -29,6 +29,7 @@ #include #include "thermal_core.h" +#include "thermal_hwmon.h" #define TSENSOR_CFG_REG1 0x4 #define TSENSOR_CFG_REG1_RSET_VBG BIT(12) @@ -287,6 +288,9 @@ static int amlogic_thermal_probe(struct platform_device *pdev) return ret; } + if (devm_thermal_add_hwmon_sysfs(pdata->tzd)) + dev_warn(&pdev->dev, "Failed to add hwmon sysfs attributes\n"); + ret = amlogic_thermal_initialize(pdata); if (ret) return ret; -- 2.30.2
