[PATCH 0/2] Add support for es8323 on the firefly-rk3288

[Romain Perier]

This set of patches enables support for the es8323 codecs on the
firefly-rk3288. It adds the required DT definitions to link rockchip-i2s
to the es8388 analog output.

[PATCH 1/2] SoC: es8328-i2c: Add compatible for ES8323

[Romain Perier]

This commit adds a compatible string for everest,es8323. This is an
audio codec that is compatible with es8328 and can be found for example
on the Firefly-RK3288 board.
