regulator: ab8500: delete non-devicetree probe path

2013-12-03T15:09:06+00:00

The Ux500 platform has been converted to do device-tree only
boots, no longer supports platform data passing, so this
probe path is unused. Delete it, simplifying the driver a
whole lot.

regulator: ab8500: Provide supply names for the AUX regulators

2013-06-11T11:50:00+00:00

On some platforms the AUX[1|2|3] regulators are supplied voltage by
a separate regulator. For example on Snowball these are provided by
the EXT3. If we list them here, we can supply voltage to them by
simply listing them in as a consumer of EXT3 in the Snowball case.

regulator: ab8500-ext: Register as a device in its own right

2013-06-11T11:50:00+00:00

Some platforms don't support the AB8500 external regulators, so instead
of having a list of is_() calls prior to calling
ab8500_ext_regulator_init() from ab8500_regulator_probe(), we can only
register as a platform device on platforms which require them. It means
we also have more control over them when booting with Device Tree.

regulator: ab8500: Get rid of voltage_shift field from struct ab8500_regulator_info

2013-04-18T17:26:35+00:00

The voltage_shift can be calculated from voltage_mask.
Let's remove voltage_shift fied from struct ab8500_regulator_info, this change
can prevent missing voltage_shift setting issue.

regulator: ab8500: Fix set voltage for AB8540_LDO_AUX3

2013-04-17T14:09:27+00:00

When setting voltage for AB8540_LDO_AUX3, current code only updates one of
info->voltage_reg and info->expand_register registers which is wrong.
To ensure we set to correct voltage, it always needs to clear or set
expand_register.voltage_mask bit of expand_register.

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.
When leaving 3.05V for another voltage, set the target voltage before clearing
the expand register bit.

regulator: ab8500: Don't update lp_mode_req flag in set_mode() error paths

2013-04-17T14:08:27+00:00

Currently, set invalid mode setting for shared mode regulators may change
sm->lp_mode_req flag. This patch ensures we don't set lp_mode_req flag to wrong
status if set_mode() fails.

This patch includes some clean up, and these changes makes this patch looks like
code refactor. The clean up is mainly to avoid adding ugly code to handle
failure paths.
