Subject: [PATCH 5.4 52/76] ASoC: meson: axg-tdmin: fix axg skew offset

From: Jerome Brunet <jbrunet@...libre.com>

commit a84dfb3d55934253de6aed38ad75990278a2d21e upstream.

The signal captured on from tdm decoder of the AXG SoC is incorrect. It
appears amplified. The skew offset of the decoder is wrong.

Setting the skew offset to 3, like the g12 and sm1 SoCs, solves and gives
correct data.
