Date: Sat, 25 Jan 2014 18:14:36 +0100 From: Jean-Francois Moine <moinejf@...e.fr> To: dri-devel@...ts.freedesktop.org Cc: Dave Airlie <airlied@...il.com>, Rob Clark <robdclark@...il.com>, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, Russell King - ARM Linux <linux@....linux.org.uk> Subject: [PATCH v4 18/24] drm/i2c: tda998x: set the PLL division factor in range 0..3 The predivider division factor of the register PLL_SERIAL_2 is in the range 0..3, the value 0 being used for a division by 1.
