2014-05-27regulator: pfuze100: Support enable/disable for fixed regulatorAxel Lin
Current code has .enable_reg and .enable_mask settings, but the implementation for corresponding callbacks are missing. Fix it.

2014-05-26regulator: pfuze100: Don't allocate an invalid gpioSean Cross
Previously, the PFUZE100 would try to allocate gpio0 io0 because config.ena_gpio defaults to 0, which can be a valid GPIO. To prevent this from happening, set this parameter to -EINVAL. Signed-off-by: Sean Cross <xobs@kosagi.com> Signed-off-by: Mark Brown <broonie@linaro.org>

Since commit d7857c42 (regulator: pfuze100: Use of_get_child_by_name) we get the following probe failure: pfuze100-regulator 1-0008: Full layer: 1, Metal layer: 0 pfuze100-regulator 1-0008: FAB: 0, FIN: 0 pfuze100-regulator 1-0008: regulators node not found pfuze100-regulator: probe of 1-0008 failed with error -22 Now that of_get_child_by_name() is used we should adjust the device_node pointer 'np' to not get the parent node anymore.

2013-07-31regulator: pfuze100: Simplify pfuze100_set_ramp_delay implementationAxel Lin
Simplify the equation to calculate ramp_delay. Below equations are equivalent: ramp_delay = 25000 / (2 * ramp_delay); ramp_delay = 50000 / (4 * ramp_delay); ramp_delay = 25000 / (2 * ramp_delay); ramp_delay = 12500 / ramp_delay; So we don't need to read BIT6 of rdev->desc->vsel_reg for applying different equations. Also use rdev->desc->vsel_reg instead of run-time calculate register address.

2013-07-30regulator: pfuze100: Fix n_voltages setting for SW2~SW4 with high bit setAxel Lin
Current code adjust min_uV and uV_step but missed adjusting the n_voltages setting. When BIT6 is clear: n_voltages = (1975000 - 400000) / 25000 + 1 = 64 When BIT6 is set: n_voltages = (3300000 - 800000) / 50000 + 1 = 51 The n_voltages needs update because when BIT6 is set 0x73 ~ 0x7f are reserved. When using regulator_list_voltage_linear, the n_voltages does matter here because wrong n_voltages setting make the equation return wrong result. e.g. if selector is 63, regulator_list_voltage_linear returns 800000 + (50000 * 63) = 4000000 It should return -EINVAL if the selector is in the range of 51 ~ 63.
