Subject: [PATCH 1/2] ARM: dts: imx6qdl-wandboard: Fix audio channel swap
Date: Sun, 14 May 2017 11:50:50 -0300	[thread overview]
Message-ID: <1494773451-11111-1-git-send-email-festevam@gmail.com> (raw)

From: Fabio Estevam <fabio.estevam@nxp.com>

When running a stress playback/stop loop test on a mx6wandboard channel
swaps can be noticed randomly.

Increasing the SGTL5000 LRCLK pad strength to its maximum value fixes
the issue, so add the 'lrclk-strength' property to avoid the audio
channel swaps.
