Message-Id: <5300a7cd7ed2f88488ddba62947b9c6bb9663777.1396122227.git.mschiffer@universe-factory.net>

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.
