From 5300a7cd7ed2f88488ddba62947b9c6bb9663777 Mon Sep 17 00:00:00 2001 Message-Id: <5300a7cd7ed2f88488ddba62947b9c6bb9663777.1396122227.git.mschiffer@universe-factory.net> From: Matthias Schiffer Date: Sat, 29 Mar 2014 20:26:08 +0100 Subject: [PATCH 1/2] MIPS: ath79: add support for QCA953x SoC Note that the clock calculation looks very similar to the QCA955x, but the meaning of the bits CPUCLK_FROM_CPUPLL and DDRCLK_FROM_DDRPLL is reversed. --- arch/mips/ath79/Kconfig | 6 +- arch/mips/ath79/clock.c | 78 ++++++++++++++++++++++++++ arch/mips/ath79/common.c | 4 ++
