cover arm64: dts: freescale: imx8mm/imx8mp-verdin-dahlia: add Microphone Jack to sound card

This patch series adds a Microphone Jack to the simple-audio-card of the Verdin iMX8MM and iMX8MP Dahlia carrier board device trees to separate the microphone and headphone functions.

This resolves the following boot-time kernel log message, which indicated a conflict when the microphone and headphone functions were not separated:
debugfs: File 'Headphone Jack' in directory 'dapm' already present!

PATCH 1/2 arm64: dts: freescale: imx8mp-verdin-dahlia: add Microphone Jack to sound card

From: Stefan Eichenberger <[email protected]>

The simple-audio-card's microphone widget currently connects to the headphone jack. Routing the microphone input to the microphone jack allows for independent operation of the microphone and headphones.

This resolves the following boot-time kernel log message, which indicated a conflict when the microphone and headphone functions were not separated:
debugfs: File 'Headphone Jack' in directory 'dapm' already present!

Fixes 874958916844 ("arm64: dts: freescale: verdin-imx8mp: dahlia: add sound card")
