From 2439d70c52c51f991b00b0ae5644e96033bd8165 Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Mon, 22 Nov 2021 12:37:39 +0100 Subject: [PATCH] ARM: dts: imx6qdl-tqma6: add ERR006687 hardware workaround for "a" variant The TQMa6x "a" has a workaround for ERR006687 implemented in hardware. Add the required pinmuxing and related setup to make use of this. As board DTS files based on the TQMa6x SoMs will define their own pinmuxing for the FEC ethernet controller as well, we can't apply this pin group unconditionally; instead, it is the responsibility of the board DTs derived from imx6qdl-tqma6a.dtsi to include this group.
