* hwmon: (ina2xx) Remove casting the return value which is a void pointerJingoo Han2013-09-101-2/+1
| | | | | | | | | | Casting the return value which is a void pointer is redundant. The conversion from void pointer to any other pointer type is guaranteed by the C programming language.

* hwmon: use dev_get_platdata()Jingoo Han2013-08-111-2/+2
| | | | | | | | Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
* hwmon: (ina2xx) Add device tree support to pass the shunt resistorTang Yuantian2013-06-271-0/+5
| | | | | | | | | Adding another way that is device tree to pass the shunt resistor value to driver except for platform data. Signed-off-by: Tang Yuantian <Yuantian.Tang@freescale.com> [Guenter Roeck: Added missing of.h include] Signed-off-by: Guenter Roeck <linux@roeck-us.net>

* hwmon: (ina2xx) use module_i2c_driver to simplify the codeWei Yongjun2012-12-051-12/+1
| | | | | | | | | | | Use the module_i2c_driver() macro to make the code smaller and a bit simpler. dpatch engine is used to auto generate this patch. (https://github.com/weiyj/dpatch) Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
* hwmon: Add missing inclusions of <linux/jiffies.h>Jean Delvare2012-10-101-0/+1
| | | | | | | | | | | | Many hwmon drivers use jiffies but omit the inclusion of the header file. Fix that, and also fix one driver which was including the header file but didn't need it.

* hwmon: (ina2xx) Add support for INA220 and INA230Guenter Roeck2012-09-231-0/+10
| | | | | | | | | INA220 is register compatible to INA219, and INA230 is register compatible to INA226, so all we need to do is to add name aliases for those two chips.

* hwmon: (ina2xx) Use structure array to distinguish chip typesGuenter Roeck2012-09-231-103/+56
| | | | | | | | | | | | Replace per-device initialization and per-device calculation code with per-device configuration data, which is then used to configure the chip and perform calculations based on that data. This patch reduces code size by more than 400 bytes on x86_64. Cc: Lothar Felten <l-felten@ti.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (ina2xx) Fix word size register read and write operationsGuenter Roeck2012-09-121-21/+9
| | | | | | | | | | | | | | The driver uses be16_to_cpu and cpu_to_be16 to convert data in SMBus word operations from chip to host byte order. However, the data passed from and to the SMBus word API functions is in host byte order, not in chip byte order. Conversion should therefore use swab16 instead of be16 to change the byte order. Replace driver internal word conversion functions with SMBus API functions to solve the problem.
