From 49a1bc3ee7d75136004911b687a2508cda06d793 Mon Sep 17 00:00:00 2001 From: blogic Date: Mon, 17 Aug 2015 06:15:49 +0000 Subject: [PATCH] ramips: Fix MT7621 pinmux bits for uart3, uart2, mdio The MT7621 uses a 2 bit wide configuration of the sdhci, spi, mdio, pcie, wdt, uart2 and uart3 in the GPIO_MODE register. It was correctly done for sdhci, spi, pcie and wdt, The same has to be done for uart3, uart2 and mdio.
