Subject: [PATCH RFC 0/3] ASoC: qcom: x1e80100: Add sound card support for
 Dell XPS13 9345

The current X Elite driver for sound card is mapping the channels from
left to right on all X Elite based laptops. The Dell XPS13 9345 seems to
be the one-off when the speakers/tweeters are mapped starting from right
to left.

So rework the driver to bring in a swapped mapping for 4 channels setups
and use it with the dedicated XPS13 compatible.

The devicetree node is included for proof-of-concept purposes.

Sending this as an RFC since it probably will need more discussion
before settling on the approach on how to handle this properly on future
devices.
