This patch removes the old method of jack detection from palm27x-asoc driver and adds jack detection api. It also removes some other (now) useless stuff from the driver and corrects pin configuration for the codec.

The patch adds a few small enhancements to the ASoC jack handling, as suggested by Mark in his comments to my Amstrad Delta driver, and a few fixes for related bugs found while learning Mark's code and testing results. Enhancements: 1. Update status of an ASoC jack while associating it with new gpios. 2. Really update DAPM pins while associating them with an ASoC jack. 3. Export ASoC jack gpios over gpiolib sysfs for diagnostic purposes. Fixes: 1. Apply mask on jack status report before using it, just for case. 2. While updating jack associated DAPM pins, use full resulting jack status, not the status report passed as an argument. Created and tested on linux-2.6.31-rc3 Signed-off-by: Janusz Krzysztofik <jkrzyszt@tis.icnet.pl> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

The MAX9877 needs an address of start register when we write values to registers through i2c_master_send(), but the code for this was missed in max9877_write_regs(). If the value of control is 0 in the max9877_set_out_mode(), the value is not increased to 1, but actually the value to write to the register should be 1. And the register bits for out_mode and osc_mode should be cleared before writing.

This patch adds support for Conexant CX20442-11 voice modem codec, suitable for use by the ASoC board driver for Amstrad E3 (Delta) videophone. Related sound card driver will follow. This codec is an optional part of the Conexant SmartV three chip modem design. As such, documentation for its proprietary digital audio interface is not available. However, on Amstrad Delta board, thanks to Mark Underwood who created an initial, omap-alsa based sound driver a few years ago[1], the codec has been discovered to be accessible not only from the modem side, but also over the OMAP McBSP based CPU DAI. Thus, the driver can be used by any sound card that can access the codec DAI directly. The DAI configuration parameters (sample rate and format, number of channels) has been selected out empirically for best user experience. The codec analogue interface consists of two pairs of analogue I/O pins: speakerphone interface or telephone handset/headset interface. Furthermore, it seams to provide two operation modes for speakerphone I/O: standard and advanced, with automatic gain control and echo cancelation. Even if the codec control interface is unknown and not available, all those interfaces and modes can be selected over the modem chip using V.253 commands. The driver is able to issue necessary commands over a suitable hw_write function if provided by a sound card driver. Otherwise, the codec can be controlled over the modem from userspace while inactive. Even if nothig is known about the codec internal power management capabilities, DAPM widgets has been used to model the codec audio map. Automatically performed powering up/down of those virtual widgets results in corresponding V.253 commands being issued. Some driver features/oddities may be board specific, but I have no way to verify that with any board other than Amstrad Delta. [1] http://www.earth.li/pipermail/e3-hacking/2006-April/000481.html Created and tested against linux-2.6.31-rc3. Applies and works with linux-omap-2.6 commit 7c5cb7862d32cb344be7831d466535d5255e35ac as well.

PLL was not being enabled when it was not bypassed. This patch enables the PLL when it is used. Additionally, it disables the PLL when it is bypassed. Without this patch, the audio on TI DM646x EVM and DM355 EVM does not work properly. The bit clocks and the frame sync signals from the codec are not correct and hence the playback/record are faster than usual for most sample rates. The reason for this was that the PLL was not enabled when it was not bypassed. Tested on DM6467 EVM, playback tested on DM355 EVM.

The callback function to control register was used by whole controls in MAX9877 driver, but this causes using many if statement for double register control or invert. So, the callback function for double register control is separate differently, and the code for invert is added in the callback function.

Reset was failing with the original udelay(50) between the code in psc_ac97_cold_reset() and the call to psc_ac97_warm_reset(). Through testing it was found that a delay of 1ms was necessary for the cold_reset code to consistently complete successfully.

The MAX9877 combines a high-efficiency Class D audio power amplifier with a stereo Class AB capacitor-less DirectDrive headphone amplifier. The max9877_add_controls() is called to register the MAX9877 specific controls on machine specific init() of the machine driver. The datasheet for the MAX9877 can find at the following url: http://datasheets.maxim-ic.com/en/ds/MAX9877.pdf [Slight edit to sort the ALL_CODECS entries -- broonie.] Signed-off-by: Joonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

As shipped the board does not have inputs but it is relatively straightforward to modify the board to hook them up so support is provided in the driver. When these modifications have not been made enabling the microphone stage can cause problems. Add an ifdef to disable this by default. Don't put it into Kconfig since users will have to get their soldering irons out to change things. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

This simplifies the driver by removing the need to manually configure dividers within the CPU and improve audio performance by ensuring that the optimal phase relationships between the clocks in the system are maintained. Note that currently this means that for playback to work the Output Mixer HiFi switch must be enabled since otherwise CODEC will not generate the DAC clock.
