From 8474681c3eb37f65c08eb9080cef817c38ee60c4 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 13 May 2017 15:57:45 +0200 Subject: [PATCH] ARM: rmobile: salvator-x: Adjust UART clock The UART uses internal SCIF clock except on R8A7795 H3 WS1.0 . Use the internal clock and ignore the early version of the chip.
