From 492dd7309aed4d2313a6f9d9a26f88707f51161b Mon Sep 17 00:00:00 2001 From: Ivan Uvarov Date: Wed, 7 Apr 2021 14:14:25 +0300 Subject: ARM: dts: sun8i: r40: add pinmux settings for MMC3 and UARTs 2, 4, 5&7 The Forlinx OKA40i-C devboard makes use of UARTs 0,2,3,4,5 and 7 of the R40 SoC, of which UART 0 is connected to an RS232 converter, UART 5 routed to an RS485 converter, and the rest broken out directly via labeled headers. The board also contains a micro-SD slot connected to SDC3. This patch adds settings to R40's pinmux node for MMC3 and those UARTs that were not already mapped, which would allow us to make use of all available UARTs and the micro-SD slot on this board in a further patch.
