leds: Add WM8350 LED driver

2009-01-08T12:38:58+00:00

The voltage and current regulators on the WM8350 AudioPlus PMIC can be
used in concert to provide a power efficient LED driver.  This driver
implements support for this within the standard LED class.

Platform initialisation code should configure the LED hardware in the
init callback provided by the WM8350 core driver.  The callback should
use wm8350_isink_set_flash(), wm8350_dcdc25_set_mode() and
wm8350_dcdc_set_slot() to configure the operating parameters of the
regulators for their hardware and then then use wm8350_register_led() to
instantiate the LED driver.

This driver was originally written by Liam Girdwood, though it has been
extensively modified since then.

mfd: Add WM8351 support

2009-01-04T11:17:42+00:00

The WM8351 is a WM8350 variant. As well as register default changes the
WM8351 has fewer voltage and current regulators than the WM8350.

mfd: Support configurable numbers of DCDCs and ISINKs on WM8350

2009-01-04T11:17:42+00:00

Some WM8350 variants have fewer DCDCs and ISINKs. Identify these at
probe and refuse to use the absent DCDCs when running on these chips.

mfd: Add WM8352 support

2009-01-04T11:17:42+00:00

The WM8352 is a variant of the WM8350. Aside from the register defaults
there are no software visible differences to the WM8350.

power_supply: Add battery health reporting for WM8350

2009-01-04T11:17:39+00:00

Implement support for reporting battery health in the WM8350 battery
interface. Since we are now able to report this via the classs remove
the diagnostics from the interrupt handler.

mfd: Refactor WM8350 chip identification

2009-01-04T11:17:39+00:00

Since the WM8350 driver was originally written the semantics for the
identification registers of the chip have been clarified, allowing
us to do an exact match on all the fields. This avoids mistakenly
running on unsupported hardware.

Also change to using the datasheet names more consistently for
legibility and fix a printk() that should be dev_err().

mfd: Switch WM8350 revision detection to a feature based model

2009-01-04T11:17:38+00:00

Rather than check for chip revisions in the WM8350 drivers have the core
code set flags for relevant differences.

power_supply: Add support for WM8350 PMU

2009-01-04T11:17:38+00:00

This patch adds support for the PMU provided by the WM8350 which
implements battery, line and USB supplies including a battery charger.
The hardware functions largely autonomously, with minimal software
control required to initiate fast charging.

Support for configuration of the USB supply is not yet implemented.
This means that the hardware will remain in the mode configured at
startup, by default limiting the current drawn from USB to 100mA.

This driver was originally written by Liam Girdwood with subsequent
updates for submission by Mark Brown.

mfd: Add AUXADC support for WM8350

2009-01-04T11:17:38+00:00

The auxiliary ADC in the WM8350 is shared between several subdevices
so access to it needs to be arbitrated by the core driver.
