From mboxrd@z Thu Jan 1 00:00:00 1970 From: sergei.shtylyov@cogentembedded.com (Sergei Shtylyov) Date: Tue, 09 Feb 2016 01:57:22 +0300 Subject: [PATCH 1/5] ARM: dts: r8a7794: add audio clocks In-Reply-To: <4253511.vvGjIdOnb6@wasted.cogentembedded.com> References: <4253511.vvGjIdOnb6@wasted.cogentembedded.com> Message-ID: <1840385.PK7TPc1Pyy@wasted.cogentembedded.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Describe the external audio clocks (signals AUDIO_CLK[ABC]) required by the sound driver. Boards that provide audio clocks need to override the clock frequencies. This patch is based on the commit 0d3dbde84a45 ("ARM: shmobile: r8a7791: add audio clock on DTSI").
