Exynos5250 has a CLKOUT logic which can select one of the clocks (within its clock domains) and output that through XCLKOUT pin." Not sure if XCLKOUT on Arndale schematics means the same. -- Tushar Behera From mboxrd@z Thu Jan 1 00:00:00 1970 From: tushar.behera@linaro.org (Tushar Behera) Date: Fri, 26 Jul 2013 15:26:06 +0530 Subject: XCLKOUT in exynos5250 clock driver In-Reply-To: <20130725145158.GI9858@sirena.org.uk> References: <20130725145158.GI9858@sirena.org.uk> Message-ID: <51F247B6.9010902@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org On 07/25/2013 08:21 PM, Mark Brown wrote: > I appear to be missing something in the clock driver for the exynos5250. > I'm looking at the Arndale schematic and I see that the audio master > clock is connected to XCLKOUT on the SoC.
