previously burst length (BURST_LENGTH) is always set to equal
to bits_per_word, causes a 10us gap between each word in

This patch uses 32 bits transfer to simulate lower bits transfer,
and adjusts burst length runtimely to use biggeest burst length
as possible to reduce the gaps in transfer for PIO mode.

A function snd_soc_update_bits() is an application of
regmap_update_bits_base(). This function takes some arguments for bitmask
and new value, thus the arguments should be a type which has width.
However bool is used to variable for the argument. This brings truncation
and results in invalid operation.
This commit fixes this bug by using unsigned int type, instead of bool.

Thinkpad Helix 2 is a tablet PC, the audio is powered by Core M
broadwell-audio and rt286 codec. For all versions of Linux kernel,
the stereo output doesn't work properly when earphones are plugged
in, the sound was coming out from both channels even if the audio
contains only the left or right channel. Furthermore, if a music
recorded in stereo is played, the two channels cancle out each other
out, as a result, no voice but only distorted background music can be
heard, like a sound card with builtin a Karaoke sount effect.
Apparently this tablet uses a combo jack with polarity incorrectly
set by rt286 driver. This patch adds DMI information of Thinkpad Helix 2
to force_combo_jack_table[] and the issue is resolved. The microphone
input doesn't work regardless to the presence of this patch and still
needs help from other developers to investigate.

signals and vblank interrupts. This 1 to 1 relationship is represented
in the device tree. On some systems there is an intermediate DRC

Pointers to both matching components must be provided when initializing
