2012-07-09mfd: Remove custom wm8350 cache implementationMark Brown1-19/+0
Since none of the users now reference the cache directly we can happily remove the custom cache code and rely on the regmap cache. For simplicity we don't bother with the register defaults tables but instead read the defaults from the device - regmap is capable of doing this, unlike our old cache infrastructure. This saves a lot of code and allows us to cache the device revision information too.

2012-07-09mfd: Add regmap cache support for wm8350Mark Brown1-1/+6
Use the most simple possible transformation on the existing code so keep the table sitting around, further patches in this series will delete the existing cache code - the main purpose of this patch is to ensure that we always have a cache for bisection.

2012-05-07mfd: Convert wm8350 physical I/O to regmap APIMark Brown1-7/+2
The driver still uses a custom cache implementation but the underlying physical I/O is now done using the regmap API, saving some code and avoiding allocating enormous scratch arrays on the stack.

2010-11-10ASoC: Remove broken WM8350 direction constantsMark Brown1-3/+0
The WM8350 driver was using some custom constants to interpret the direction of the MCLK signal which had the opposite values to those used as standard by the ASoC core, causing confusion in machine drivers such as the 1133-EV1 board.

2010-03-07mfd: Use completion interrupt for WM835x AUXADCMark Brown1-0/+2
Use the completion interrupt generated by the device rather than polling for conversions to complete. As a backup we still check the state of the AUXADC if we don't get a completion, mostly for systems that don't have the WM8350 interrupt infrastructure hooked up.

2010-03-07mfd: Convert WM8350 to genirqMark Brown1-13/+31
This gives us use of the diagnostic facilities genirq provides and will allow implementation of interrupt support for the WM8350 GPIOs. Stub functions are provided to ease the transition of the individual drivers, probably after additional work to pass the IRQ numbers via the struct devices.

2010-03-07rtc: Suppress duplicate enable/disable of WM8350 update interruptMark Brown1-0/+1
Unlike the wm8350-custom code genirq nests enable and disable calls so we can't just unconditionally mask or unmask the interrupt, we need to remember the state we set and only mask or unmask when there is a real change.

2010-01-18mfd: Correct WM835x ISINK ramp time definesMark Brown1-14/+14
The constants used to specify ISINK ramp times for WM835x had the wrong shifts so that the on times applied to the off ramp and vice versa. The masks for the bitfields are correct.

2009-12-13mfd: Convert wm8350 IRQ handlers to irq_handler_tMark Brown1-4/+4
This is done as simple code transformation, the semantics of the IRQ API provided by the core are are still very different to those of genirq (mainly with regard to masking). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-12-13mfd: Allow platforms to specify an IRQ base for WM8350Mark Brown1-0/+2
This is currently unused by the wm8350 drivers but getting it merged now will reduce merge issues in the future when implementing wm8350 genirq support. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-12-13mfd: Convert WM835x IRQ handling to use a data tableMark Brown1-0/+18
Rather than open coding individual IRQs in each function which manipulates them store data for IRQs in a table which is then referenced in the users. This is a substantial code shrink and should be a performance win in cases where only a single IRQ goes off at once since instead of reading four of the second level IRQ registers for each interrupt we read only the sub-registers which have had an interrupt flagged.

2009-12-13mfd: Split wm8350 IRQ code into a separate fileMark Brown1-1/+3
In preparation for refactoring - it's over 700 lines of well-isolated code and having it in a file by itself makes things more managable. While we're at it make sure that we clean up the IRQ if we fail after acquiring it on init.

2009-01-08leds: Add WM8350 LED driverMark Brown1-0/+36
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.

2009-01-04mfd: Refactor WM8350 chip identificationMark Brown1-0/+6
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().

2009-01-04power_supply: Add support for WM8350 PMUMark Brown2-1/+48
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.

2008-12-18ASoC: Add WM8350 AudioPlus codec driverMark Brown1-4/+34
The WM8350 is an integrated audio and power management subsystem which provides a single-chip solution for portable audio and multimedia systems. The integrated audio CODEC provides all the necessary functions for high-quality stereo recording and playback. Programmable on-chip amplifiers allow for the direct connection of headphones and microphones with a minimum of external components. A programmable low-noise bias voltage is available to feed one or more electret microphones. Additional audio features include programmable high-pass filter in the ADC input path.

2008-10-13mfd: Add WM8350 interrupt supportMark Brown1-1/+20
The WM8350 has an interrupt line to the CPU which is shared by the devices on the CPU. This patch adds support for the interrupt controller within the WM8350 which identifies which identifies the interrupt cause. In common with other similar chips this is done outside the standard interrupt framework due to the need to access the interrupt controller over an interrupt-driven bus.

2008-10-13mfd: Add GPIO pin configuration support for WM8350Mark Brown1-0/+10
The WM8350 provides a number of user-configurable pins providing access to various signals generated by the functions on the chip. These are referred to as GPIO pins in the device documentation but in Linux terms they are more general than that, providing configuration of alternate functions. This patch implements support for selecting the alternate functions for these pins. They can also be used as GPIOs in the normal Linux sense - a subsequent patch will add support for doing so. This code was all written by Liam Girdwood and has had minor updates and rearrangements by Mark Brown.

The WM8350 is an integrated audio and power management subsystem intended for use as the primary PMIC in mobile multimedia applications. The WM8350 can be controlled via either I2C or SPI - the control interface is provided by a separate module in order to allow greatest flexibility in configuring the kernel. This driver was originally written by Liam Girdwood and has since been updated to current kernel APIs and split up for submission by me. All the heavy lifting here was done by Liam.
