Subject: ARM: dts: imx6qdl-colibri: Fix audio channel swap
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7d098b9108215ce8c5de545a46737f330f83ba2a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: dts: imx6qdl-colibri: Fix audio channel swap

When running a stress playback/stop loop test on a mx6colibri 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.
