* regulator: tps65910: Convert to use regulator_map_voltage_ascendAxel Lin2013-04-23
| | | | | | | | | | | | | | | | | | All regulators have ascendant voltage list in this driver. Some regulators have more than 200 supported voltages. e.g. For TPS65910_REG_VDD1 and TPS65910_REG_VDD2: n_voltages = VDD1_2_NUM_VOLT_FINE * VDD1_2_NUM_VOLT_COARSE = 73 * 3 = 219 Thus it worth converting to regulator_map_voltage_ascend rather than use default regulator_map_voltage_iterate. For consistent, convert all regulators to regulator_map_voltage_ascend. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* regulator: Add missing of_node_put()Axel Lin2013-01-30
| | | | | | | | | | | | of_find_node_by_name() returns a node pointer with refcount incremented, use of_node_put() on it when done. of_find_node_by_name() will call of_node_put() against from parameter, thus we also need to call of_node_get(from) before calling of_find_node_by_name().

* regulator: tps65910: Fix using wrong dev argument for calling of_regulator_matchAxel Lin2013-01-24
| | | | | | | | | | | | | The dev parameter is the device requesting 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.

| | | | | | | | | | | | | | tps65910_reg_[read|modify_bits|read_locked|write_locked] functions The tps65910 mfd driver has been converted to regmap APIs. This patch adds tps65910_reg_update_bits() in include/linux/mfd/tps65910.h. Thus we can use tps65910_reg_read/tps65910_reg_write/tps65910_reg_update_bits directly and remove tps65910_reg_[read|modify_bits|read_locked|write_locked] functions.

* regulator: tps65910: correct init value of n_voltagesLaxman Dewangan2012-07-10
| | | | | | | | | | | | | Recent change in the core driver to get the maximum voltage is based on the (n_voltages -1) steps of voltage. For the tps65910, the (n_voltages -1)th step voltage is calculated based on the callback function list_voltage. This function direct maps the datasheet and adjust the first few steps for initial voltage as per datasheet, and hence initialize the n_voltages based on datasheet.

* regulator: tps65910: Remove unused min_uV and max_uV from struct tps_infoAxel Lin2012-06-22
| | | | | | | | | | | | | | | The min_uV and max_uV fields of struct tps_info are not used in the code. For the case voltage_table is provided, the min_uV and max_uV are the same values as volt_table[0] and volt_table[n_voltages -1]. For the case voltage_table is not available, having the min_uV and max_uV seems misleading. Current code uses equations to get the voltage value in this case, but these equations do not use the min_uV and max_uV fields of struct tps_info. Thus this patch removes the min_uV and max_uV fields from struct tps_info.

* / regulator: tps65910: Configure correct value for VDDCTRL vout regLaxman Dewangan2012-03-07
|/ | | | | | | | | | | | | | | | As per datasheet, the voltage output is defined as from SEL[6:0] = 3 to 64 (dec) Vout= (SEL[6:0] × 12.5 mV + 562.5 mV) The list_voltage returns the vout as 600mV + selector * 12.5mV and so equivalent VSEL is selector + 3. Adding 3 on selector when configuring VSEL register for VDDCTRL output. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

| * regulator: pass additional of_node to regulator_register()Rajendra Nayak2011-11-23
| | | | | | | | | | | | | | | | | | | | | | With device tree support for regulators, its needed that the regulator_dev->dev device has the right of_node attached. To be able to do this add an additional parameter to the regulator_register() api, wherein the dt-adapted driver can then pass this additional info onto the regulator core.
