* regulator: twl: add twl6030 get_statusSaquib Herman2011-05-271-9/+35
| | | | | | | | | | | | | Current get_status logic does not support 6030 get_status. The logic for 4030 is not reusable for 6030 as the status check for 6030 now depends on the new CFG_STATE register. We hence rename the old get_status as being specific to 4030 and remove the redundant check for the same.

* regulator: twl: fix twl6030 regulator is_enabledSaquib Herman2011-05-271-15/+46
| | | | | | | | | | | | | | | | With TWL6030, it is not enough to ensure that the regulator is the group of P1 group (CPU/Linux), but we need to check the state as far as APP is concerned as well. Split the current is_enabled to 6030 and 4030 specific ones. This split impacts few macros and variables as well, but sets up the stage for further fixes to set_mode and get_status in subsequent patches.

* regulator: twl: remap has no meaning for 6030Saquib Herman2011-05-271-20/+17Star
| | | | | | | | | | | | | | | | TWL6030 does not have remap register. The current implementation causes value of remap to be written to state register, accidentally causing the regulators which are probed to be switched on as well. This is wrong as regulators should be controllable based on calls to enable/disable for TWL regulator framework. Further, the values initialized make no sense as well. We hence remove this from the initalizers and also write to remap register only if the TWL is 4030.

* regulator: twl: fix twl6030 enable/disableSaquib Herman2011-05-271-1/+30
| | | | | | | | | | | | | TWL6030 requires an additional register write to CFG_STATE register to explicitly state that the regulator is in a certain state. Merely associating the regulator with the group is not enough. Add the required register field definitions and fix the handling for TWL6030 enable/disable.

* regulator: twl: add clk32kg to twl-regulatorBalaji T K2011-03-231-1/+23
| | | | | | | | | | | | In OMAP4 Blaze and Panda, 32KHz clock to WLAN is supplied from Phoenix TWL6030. The 32KHz clock state (ON/OFF) is configured in CLK32KG_CFG_[GRP, TRANS, STATE] register. This follows the same register programming model as other regulators in TWL6030. So add CLK32KG as pseudo regulator.

* regulator: Report actual configured voltage to set_voltage()Mark Brown2011-01-121-3/+8
| | | | | | | | | | | Change the interface used by set_voltage() to report the selected value to the regulator core in terms of a selector used by list_voltage(). This allows the regulator core to know the voltage that was chosen without having to do an explict get_voltage(), which would be much more expensive as it will generally access hardware.

* regulator: twl-regulator - fix twlreg_set_modeAxel Lin2010-11-301-3/+3
| | | | | | | | | | | | | | | | | | The Singular Message is 16 bits: DEV_GRP[15:13] MT[12] RES_ID[11:4] RES_STATE[3:0] Current implementation return immedially after sucessfuly write MSB part. To properly set mode, we need to write the complete message ( MSB and LSB ). In twl.h, now we have defines for PM Master module register offsets, use it instead of hard coded 0x15/0x16. Use "message & 0xff" to ensure we send correct value for LSB.

* twl6030: regulator: Remove vsel tables and use formula for calculationRajendra Nayak2010-05-251-47/+91
| | | | | | | | | | | | | | | | | | | | | | All twl6030 regulators can be programmed from 1.0v to 3.3v with 100mV steps. The below formula can be used to calculate the vsel values to be programmed in the VREG_VOLTAGE registers. Voltage(in mV) = 1000mv + 100mv * (vsel - 1) Ex: if vsel = 0x9, mV = 1000 + 100 * (9 -1) = 1800mV. This patch removes all existing VSEL tables for twl6030 adjustable regulators and just uses the formula directly for vsel calculations after verifing they fall in the allowed range.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This is no REMAP register on twl6030, instead there is a STATE register to drive a resource to a given state. The state register can be used to specify what state the resource should enter when its associated with a GRP. Register Bit field description is as below. The patch programmes the corresponding STATE registers for all LDO's to turn ON when assocaited with GRP_P1.
