[PATCH v2 06/16] ARM: dts: imx6qdl-sr-som: split out Broadcom Wi-Fi support

Tue Nov 28 07:02:25 PST 2017
There are two variants of the imx6qdl som: one with Broadcom Wi-Fi and
another with Texas Instruments Wi-Fi. The two Wi-Fi devices require
different DT bindings, so it's necessary to split out the Broadcom
specifics.
