Subject: [PATCH v2 0/2] RZ/G2L SSI full duplex fixes

From: Biju Das <biju.das.jz@...renesas.com>

The first patch in this series fixes audio channel swap issue because of
half duplex to full duplex switching during the streaming that involves
FIFO reset which drops the word leading to audio channel swap issue. The
second patch fixes sample width value in the hw_params_cache::sample_width

v1->v2:
 * Split the fixes patches separate.
 * Improved code logic in rz_ssi_start() by using else if
 * Collected tags from Morimoto-san

Biju Das (2):
  ASoC: renesas: rz-ssi: Fix channel swap issue in full duplex mode
  ASoC: renesas: rz-ssi: Fix rz_ssi_priv::hw_params_cache::sample_width
