Subject: [PATCH AUTOSEL 5.2 100/249] ASoC: meson: axg-tdm: fix sample clock inversion
Date: Mon, 15 Jul 2019 09:44:25 -0400 [thread overview]
Message-ID: <20190715134655.4076-100-sashal@kernel.org> (raw)
In-Reply-To: <20190715134655.4076-1-sashal@kernel.org>
From: Jerome Brunet <jbrunet@baylibre.com>
[ Upstream commit cb36ff785e868992e96e8b9e5a0c2822b680a9e2 ]
The content of SND_SOC_DAIFMT_FORMAT_MASK is a number, not a bitfield,
so the test to check if the format is i2s is wrong. Because of this the
clock setting may be wrong. For example, the sample clock gets inverted
in DSP B mode, when it should not.
Fix the lrclk invert helper function
