Bring the WM8350 IRQ API more in line with the generic IRQ API by masking and unmasking interrupts as they are requested and freed. This is mostly just a case of deleting the mask and unmask calls from the individual drivers. The RTC driver is changed to mask the periodic IRQ after requesting it rather than only unmasking the alarm IRQ. If the periodic IRQ fires in the period where it is reqested then there will be a spurious notification but there should be no serious consequences from this. The CODEC drive is changed to explicitly disable headphone jack detection prior to requesting the IRQs. This will avoid the IRQ firing with no jack set up.

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: NMark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: NSamuel Ortiz <sameo@linux.intel.com>

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.

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.

Due to the way that the WM8350 audio driver handles CODEC_ENA many of the WM8350 audio registers are marked as volatile when they aren't actually so. Allow the audio driver to see a cache of these values for inspection during interrupt context. To do this we need to stop satisfying any bits from volatile registers from cache - there's no real benefit from doing so anyway, we did the read already.

Some I2C controllers have high overheads for setting up I2C operations which makes the register cache setup on startup excessively slow since it does a lot of small transactions. Reduce this overhead by doing a bulk read of the entire register bank and filtering out what we don't need later.

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.

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.

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.

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.
