[PATCH] ARM: dts: imx6ull-dhcor: Handle both 1DX and 1YN WiFi on i.MX6ULL DHCOR

From: Marek Vasut

Date: Mon Feb 09 2026 - 12:12:44 EST


The muRata 1DX WiFi/BT chip is mounted on the DHCOM i.MX6ULL. This chip
has been discontinued and replaced by the muRata 1YN chip. The new chip
is a drop-in replacement of the old chip. To support both chips for the
i.MX6ULL DHCOR, drop the more specific compatible string and let the
driver auto-detect the chip type. Currently, there are no known quirks
that would apply only to one or the other chip.
