From: Michael Srba <redacted> This patch adds the clock-frequency property to all device trees that use the imx219 binding, with the value of exactly 24Mhz which was previously implicitly assumed. Signed-off-by: Michael Srba <redacted>Thanks for your patch!quoted

My bad, I must have been really tired. will rectify this
