Dear all,

This is a request to backport b7dc7205b2ae6b6c9d9cfc3e47d6f08da8647b10
(Arm: dts: imx6qdl-sr-som-ti: indicate powering off wifi is safe),
already in Linus tree
(https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch/arm/boot/dts/imx6qdl-sr-som-ti.dtsi?h=v5.7-rc3&id=b7dc7205b2ae6b6c9d9cfc3e47d6f08da8647b10)
to LTS kernel 5.4 and to stable 5.6.8.

Reasoning:

Changes to the wlcore driver during Kernel 5.x development, made the
Cubox-i with the IMX SOM v1.5 (which includes.a TI Wilink 8 wifi
chipset) not power the wireless interface on boot leaving it
completely unusable. This happens since at least kernel 5.3 (older one
I tested) and affects the current stable and LTS latest kernels. The
linked commit, already in linux mainline, restores the wifi
functionality.

Thanks in advance,

Miguel B Freitas
