---
ALC286 is a dual mode codec, which can run as HD-A or I2S mode.
It is controlled by HD-A verb commands via I2C protocol.
The following is the I/O difference between ALC286 and general I2S codecs.
1. A HD-A verb command contains three parts, NID, VID, and PID.
And an I2S command contains only two parts: address and data.
2. Not only the register address is written, but the read command also
includes the entire write command.
3. rt286 uses different registers for read and write the same bits.
As a result, standard regmap is difficult to be used on ALC286.
We don't request a standard I/O by snd_soc_codec_set_cache_io anymore.
Now we have ,reg_write and .reg_read functions for ALC286's I/O.
And we don't use cache due to item 3 above.
Some dummy registers (address <= 0xff) are defined for dapm routing.
Thhe dummy registers are cache only.
Due to item 2 above, HD-A verb commands are put into the address part of regmap.
When we issue HD-A verb write commands, the data part of regmap is zero.
The jack detection function is done by Lewandowski Gustaw.
So I add Gustaw's Signed-off-by line in this patch
The difference between this version and previous version is listed below.
* Use regmap_read/write instead of rt286_read/write to read write codec.
* Use the standard jack detection APIs for jack detection.
* Power off on bias level STANDBY.
* Add .symmetric_rates = 1.
* Add gpio2_en and remove irq_en in platform data.
* Other minor changes.
