Subject: [PATCH 4.9 079/148] ASoC: rcar: avoid SSI_MODEx settings for SSI8
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuninori Morimoto <kuninori.morimoto.gx@...esas.com>
[ Upstream commit 4b30eebfc35c67771b5f58d9274d3e321b72d7a8 ]
SSI8 is is sharing pin with SSI7, and nothing to do for SSI_MODEx.
It is special pin and it needs special settings whole system,
but we can't confirm it, because we never have SSI8 available board.
This patch fixup SSI_MODEx settings error for SSI8 on connection test,
but should be confirmed behavior on real board in the future.
