2013-05-12regulator: Remove all platform_set_drvdata(pdev, NULL) in driversAxel Lin1-2/+0
Since 0998d06310 "device-core: Ensure drvdata = NULL when no driver is bound", this is done by driver core after device_release or on probe failure. Thus we can remove all platform_set_drvdata(pdev, NULL) in drivers. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-01-24regulator: tps65217: Fix using wrong dev argument for calling of_regulator_matchAxel Lin1-2/+2
The dev parameter is the device requestiong the data. In this case it should be &pdev->dev rather than pdev->dev.parent. The dev parameter is used to call devm_kzalloc in of_get_regulator_init_data(), which means this fixes a memory leak because the memory is allocated every time probe() is called, thus it should be freed when this driver is unloaded.

2012-08-22mfd: Move tps65217 regulator plat data handling to regulatorAnilKumar Ch1-15/+109
Regulator platform data handling was mistakenly added to MFD driver. So we will see build errors if we compile MFD drivers without CONFIG_REGULATOR. This patch moves regulator platform data handling from TPS65217 MFD driver to regulator driver. This makes MFD driver independent of REGULATOR framework so build error is fixed if CONFIG_REGULATOR is not set. drivers/built-in.o: In function `tps65217_probe': tps65217.c:(.devinit.text+0x13e37): undefined reference to `of_regulator_match' This patch also fix allocation size of tps65217 platform data. Current implementation allocates a struct tps65217_board for each regulator specified in the device tree. But the structure itself provides array of regulators so one instance of it is sufficient.

2012-07-12regulator: tps65217: Add device tree supportAnilKumar Ch1-0/+1
This commit adds device tree support for tps65217 pmic. And usage details are added to device tree documentation. Driver is tested by using kernel module with regulator set and get APIs. Signed-off-by: AnilKumar Ch <anilkumar@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-07-03regulator: tps65217: Fix voltage boundary checking in tps65217_pmic_map_voltageAxel Lin1-3/+3
It is ok to request voltage with min_uV < tps->info[rid]->min_uV and max_uV > tps->info[rid]->max_uV. The equation we used in uv_to_vsel() does not allow min_uV < tps->info[rid]->min_uV, otherwise it returns negative selector. So we need to set min_uV = tps->info[rid]->min_uV if min_uV < tps->info[rid]->min_uV.

2012-07-01regulator: tps65217: Convert LDO1 to use regulator_list_voltage_tableAxel Lin1-25/+22
Convert tps65217_pmic_ldo1_ops to use regulator_list_voltage_table. We have n_voltages and volt_table settings in regulator_desc, so we don't need the table and table_len fields in struct tps_info. Thus remove them from struct tps_info. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-06-13regulator: tps65217: Convert to regulator_[is_enabled|get_voltage_sel]_regmapAxel Lin1-72/+42
This patch converts .is_enabled and .get_voltage_sel to regulator_is_enabled_regmap and regulator_get_voltage_sel_regmap. For .enable, .disable, and .set_voltage_sel, the write protect level is either 1 or 2. So we cannot use regulator_[enable|disable|set_voltage_sel]_regmap. Now we store the enable reg/mask and vsel reg/mask in regulator_desc, so we can remove enable_mask, set_vout_reg, and set_vout_mask from struct tps_info.

2012-05-18regulator: tps65217: Convert to set_voltage_sel and map_voltageAxel Lin1-38/+30
Convert tps65217_pmic_ops to use set_voltage_sel and map_voltage. After this convertion, we can also use tps65217_pmic_set_voltage_sel() for set_voltage_sel callback of tps65217_pmic_ldo1_ops. Thus this patch also removes tps65217_pmic_ldo1_set_voltage_sel() function. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-04-09regulator: core: Use a struct to pass in regulator runtime configurationMark Brown1-2/+6
Rather than adding new arguments to regulator_register() every time we want to add a new bit of dynamic information at runtime change the function to take these via a struct. By doing this we avoid needing to do further changes like the recent addition of device tree support which required each regulator driver to be updated to take an additional parameter. The regulator_desc which should (mostly) be static data is still passed separately as most drivers are able to configure this statically at build time.

2012-03-12regulator: Merge tps65217_pmic_ldo234_ops and tps65217_pmic_dcdc_ops to ↵Axel Lin1-187/+72
tps65217_pmic_ops Most callback functions implementation for tps65217_pmic_ldo234_ops and tps65217_pmic_dcdc_ops are the same except the rid range checking. This patch uses tps65217_pmic_ops for all DCDCx, LDO2, LDO3, and LDO4. And rework tps65217_pmic_set_voltage to make it can be called for DCDCx, LDO2, LDO3, and LDO4.
