Subject: [PATCH] ARM: dts: imx6qdl-sr-som-ti: indicate powering off wifi is safe
Date: Thu, 27 Feb 2020 12:18:51 +0000	[thread overview]
Message-ID: <E1j7I7v-0004dS-5u@rmk-PC.armlinux.org.uk> (raw)

We need to indicate that powering off the TI WiFi is safe, to avoid:

wl18xx_driver wl18xx.2.auto: Unbalanced pm_runtime_enable!
wl1271_sdio mmc0:0001:2: wl12xx_sdio_power_on: failed to get_sync(-13)

which prevents the WiFi being functional.
