From f4324583cd4d4979ff2e885a44b8335eb4c4bfa3 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Mon, 4 Apr 2022 18:47:40 +0200 Subject: [PATCH 1/3] arm64: dts: exynos: move aliases to board in Exynos850 The aliases for typical blocks which are disabled by default in DTSI (like I2C, UART and MMC) should be defined in the board DTS. The board should add aliases only for enabled blocks according to its specific order. On Exynos850, move aliases of enabled blocks to E850-96 board and remove unused ones.
