Date: Fri, 04 Nov 2011 15:50:31 +0900 From: MyungJoo Ham <myungjoo.ham@...sung.com> To: lm-sensors@...sensors.org Cc: linux-kernel@...r.kernel.org, Jean Delvare <khali@...ux-fr.org>, Guenter Roeck <guenter.roeck@...csson.com>, dg77.kim@...sung.com, kyungmin.park@...sung.com, myungjoo.ham@...il.com Subject: [RFC PATCH 0/2] HWMON: add in-kernel interfaces to read sensor values. We have been reading hwmon values (TMU, the SoC-core temperature sensor, and NTC, the ambient or battery surface temperature sensor) for Charger-Manager. However, because hwmon does not have in-kernel interface, we have been using undesired method, including "../../../fs/*.h". This patch is to provide in-kernel interface for hwmon: hwmon_get_value and hwmon_set_value. In order to use these two functions, the hwmon driver should provide its sysfs attributes to hwmon framework as well. If the hwmon driver does not provide (by providing NULL), the users of the hwmon won't be able to use hwmon_get/set_value(); The sysfs attribute (struct attribuyte_group *) is provided with hwmon_device_register; adding the second parameter to hwmon_device_register(). The 2/2 patch shows the changes in device drivers due to this. Among the HWMON device, all but ntc_thermistor.c does not setup attribute_group for HWMON; thus they do not support hwmon_get/set_value with this patch. As soon as the server synchronizes git repositories, you can see how hwmon_get_value() is used at: http://git.infradead.org/users/kmpark/linux-2.6-samsung/shortlog/refs/heads/charger-manager MyungJoo Ham (2): HWMON: add interfaces to read/write hwmon values inside kernel HWMON: adapt to the HWMON interface changes drivers/char/i8k.c | 2 +- drivers/gpu/drm/nouveau/nouveau_pm.c | 2 +- drivers/gpu/drm/radeon/radeon_pm.c | 2 +- drivers/hwmon/abituguru.c | 2 +- drivers/hwmon/abituguru3.c | 2 +- drivers/hwmon/acpi_power_meter.c | 2 +- drivers/hwmon/ad7414.c | 2 +- drivers/hwmon/ad7418.c | 2 +- drivers/hwmon/adcxx.c | 2 +- drivers/hwmon/adm1021.c | 2 +- drivers/hwmon/adm1025.c | 2 +- drivers/hwmon/adm1026.c | 2 +- drivers/hwmon/adm1029.c | 2 +- drivers/hwmon/adm1031.c | 2 +- drivers/hwmon/adm9240.c | 2 +- drivers/hwmon/ads1015.c | 2 +- drivers/hwmon/ads7828.c | 2 +- drivers/hwmon/ads7871.c | 2 +- drivers/hwmon/adt7411.c | 2 +- drivers/hwmon/adt7462.c | 2 +- drivers/hwmon/adt7470.c | 2 +- drivers/hwmon/adt7475.c | 2 +- drivers/hwmon/amc6821.c | 2 +- drivers/hwmon/applesmc.c | 2 +- drivers/hwmon/asb100.c | 2 +- drivers/hwmon/asc7621.c | 2 +- drivers/hwmon/asus_atk0110.c | 2 +- drivers/hwmon/atxp1.c | 2 +- drivers/hwmon/coretemp.c | 2 +- drivers/hwmon/dme1737.c | 4 +- drivers/hwmon/ds1621.c | 2 +- drivers/hwmon/ds620.c | 2 +- drivers/hwmon/emc1403.c | 2 +- drivers/hwmon/emc2103.c | 2 +- drivers/hwmon/emc6w201.c | 2 +- drivers/hwmon/f71805f.c | 2 +- drivers/hwmon/f71882fg.c | 2 +- drivers/hwmon/f75375s.c | 2 +- drivers/hwmon/fam15h_power.c | 2 +- drivers/hwmon/fschmd.c | 2 +- drivers/hwmon/g760a.c | 2 +- drivers/hwmon/gl518sm.c | 2 +- drivers/hwmon/gl520sm.c | 2 +- drivers/hwmon/gpio-fan.c | 2 +- drivers/hwmon/hwmon.c | 108 +++++++++++++++++++++++++++++++++- drivers/hwmon/i5k_amb.c | 2 +- drivers/hwmon/ibmaem.c | 4 +- drivers/hwmon/ibmpex.c | 2 +- drivers/hwmon/it87.c | 2 +- drivers/hwmon/jc42.c | 2 +- drivers/hwmon/jz4740-hwmon.c | 2 +- drivers/hwmon/k10temp.c | 2 +- drivers/hwmon/k8temp.c | 2 +- drivers/hwmon/lineage-pem.c | 2 +- drivers/hwmon/lm63.c | 2 +- drivers/hwmon/lm70.c | 2 +- drivers/hwmon/lm73.c | 2 +- drivers/hwmon/lm75.c | 2 +- drivers/hwmon/lm77.c | 2 +- drivers/hwmon/lm78.c | 4 +- drivers/hwmon/lm80.c | 2 +- drivers/hwmon/lm83.c | 2 +- drivers/hwmon/lm85.c | 2 +- drivers/hwmon/lm87.c | 2 +- drivers/hwmon/lm90.c | 2 +- drivers/hwmon/lm92.c | 2 +- drivers/hwmon/lm93.c | 2 +- drivers/hwmon/lm95241.c | 2 +- drivers/hwmon/lm95245.c | 2 +- drivers/hwmon/ltc4151.c | 2 +- drivers/hwmon/ltc4215.c | 2 +- drivers/hwmon/ltc4245.c | 2 +- drivers/hwmon/ltc4261.c | 2 +- drivers/hwmon/max1111.c | 2 +- drivers/hwmon/max16065.c | 2 +- drivers/hwmon/max1619.c | 2 +- drivers/hwmon/max1668.c | 2 +- drivers/hwmon/max6639.c | 2 +- drivers/hwmon/max6642.c | 2 +- drivers/hwmon/max6650.c | 2 +- drivers/hwmon/mc13783-adc.c | 2 +- drivers/hwmon/ntc_thermistor.c | 15 +---- drivers/hwmon/pc87360.c | 2 +- drivers/hwmon/pc87427.c | 2 +- drivers/hwmon/pcf8591.c | 2 +- drivers/hwmon/pmbus/pmbus_core.c | 2 +- drivers/hwmon/s3c-hwmon.c | 2 +- drivers/hwmon/sch5627.c | 2 +- drivers/hwmon/sch5636.c | 2 +- drivers/hwmon/sht15.c | 2 +- drivers/hwmon/sht21.c | 2 +- drivers/hwmon/sis5595.c | 2 +- drivers/hwmon/smm665.c | 2 +- drivers/hwmon/smsc47b397.c | 2 +- drivers/hwmon/smsc47m1.c | 2 +- drivers/hwmon/smsc47m192.c | 2 +- drivers/hwmon/thmc50.c | 2 +- drivers/hwmon/tmp102.c | 2 +- drivers/hwmon/tmp401.c | 2 +- drivers/hwmon/tmp421.c | 2 +- drivers/hwmon/twl4030-madc-hwmon.c | 2 +- drivers/hwmon/ultra45_env.c | 2 +- drivers/hwmon/via-cputemp.c | 2 +- drivers/hwmon/via686a.c | 2 +- drivers/hwmon/vt1211.c | 2 +- drivers/hwmon/vt8231.c | 2 +- drivers/hwmon/w83627ehf.c | 2 +- drivers/hwmon/w83627hf.c | 2 +- drivers/hwmon/w83781d.c | 4 +- drivers/hwmon/w83791d.c | 2 +- drivers/hwmon/w83792d.c | 2 +- drivers/hwmon/w83793.c | 2 +- drivers/hwmon/w83795.c | 2 +- drivers/hwmon/w83l785ts.c | 2 +- drivers/hwmon/w83l786ng.c | 2 +- drivers/hwmon/wm831x-hwmon.c | 2 +- drivers/hwmon/wm8350-hwmon.c | 2 +- drivers/input/touchscreen/ads7846.c | 2 +- drivers/platform/x86/asus-wmi.c | 2 +- drivers/platform/x86/compal-laptop.c | 2 +- drivers/platform/x86/eeepc-laptop.c | 2 +- drivers/platform/x86/thinkpad_acpi.c | 2 +- drivers/thermal/thermal_sys.c | 2 +- include/linux/hwmon.h | 11 +++- 124 files changed, 245 insertions(+), 139 deletions(-) -- 1.7.4.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
