| * | | regulator: lp8788: Remove lp8788_dldo_id and lp8788_aldo_id arraysAxel Lin2013-04-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The id for DLDOx matches the entries in enum lp8788_ldo_id and it's easy to calculate the id for ALDOx. Thus remove lp8788_dldo_id and lp8788_aldo_id arrays.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Regulator core driver provides enable GPIO control for enabling/disabling a regulator. Now, enable GPIO is shared among regulators. Use this internal working, so unnecessary code are removed. GPIO enable pin configurations are added in digital LDO and analog LDO drivers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support shared enable GPIO pin, replace GPIO code with new static functions Reference count: 'enable_count' Balance the reference count of each GPIO and actual pin control. The count is incremented with enabling GPIO. On the other hand, it is decremented on disabling GPIO. Actual GPIO pin is enabled at the initial use.(enable_count = 0) The pin is disabled if it is not used(shared) any more. (enable_count <=1) Regardless of the enable count, update GPIO state of the regulator.

| * | | regulator: core: support shared enable GPIO conceptKim, Milo2013-03-04
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A Regulator can be enabled by external GPIO pin. This is configurable in the regulator_config. At this moment, the GPIO can be owned by only one regulator device. In some devices, multiple regulators are enabled by shared one GPIO pin. This patch extends this limitation, enabling shared enable GPIO of regulators. New list for enable GPIO: 'regulator_ena_gpio_list' This manages enable GPIO list. New structure for supporting shared enable GPIO: 'regulator_enable_gpio' The enable count is used for balancing GPIO control count. This count is incremented when GPIO is enabled. On the other hand, it's decremented when GPIO is disabled. Reference count: 'request_count' The reference count, 'request_count' is incremented/decremented on requesting/freeing the GPIO. This count makes sure only free the GPIO when it has no users. How it works If the GPIO is already used, skip requesting new GPIO usage. The GPIO is new one, request GPIO function and add it to the list of enable GPIO. This list is used for balancing enable GPIO count and pin control. Updating a GPIO and invert code moved 'ena_gpio' and 'ena_gpio_invert' of the regulator_config were moved to new function, regulator_ena_gpio_request(). Use regulator_enable_pin structure rather than regulator_dev.

The function of the expand register bit is the following (from the user manual): 0: VAUX3 output voltage is determined by Vaux3Sel bit settings in register VldoCVaux3Sel 1: VAUX3 output voltage is set to 3.05V regardless of Vaux3Sel settings in register VldoCVaux3Sel (VldoCVaux3Sel is the register at 0x0421) So when going to 3.05V, set the expand register bit.

| * | | | regulator: ab8500-ext: Remove get_voltage to avoid duplicate implementationAxel Lin2013-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The implementation of ab8500_ext_fixed_get_voltage is identical to ab8500_ext_list_voltage. We can avoid the duplicate implementation by just remove get_voltage. For fixed regulator, regulator core will call list_voltage(rdev, 0) to get voltage if both get_voltage get_voltage_sel are not implemented.

| * | | | regulator: ab8500-ext: Remove unnecessary checking for ab9540 and ab8540Axel Lin2013-04-08

However, ab9540_ext_regulator_ops is identical to ab8500_ext_regulator_ops[2]. Thus we can complete remove the unnecessary checking for ab9540 and ab8540.
