From 020ed9c666748b103e0740622ca4128a2bd40f29 Mon Sep 17 00:00:00 2001 From: Ioana Ciornei Date: Mon, 18 May 2020 14:48:36 +0300 Subject: [PATCH] arm: dts: ls2080aqds: add CONFIG_MULTI_DTB_FIT support Add support for selecting the appropriate DTS file depending on the SERDES protocol used. The fsl-ls2080a-qds DTS will be used by default if there isn't a DTS file specifically made for the current SERDES protocol. This patch adds the necessary DPMAC nodes (DPMAC 1-8) for protocol 42 (0x2A) on SD#1. Also, in case CONFIG_DM_ETH and CONFIG_MULTI_DTB_FIT are enabled implement the board_fit_config_name_match() function in order to choose the appropriate DTS.
