From: Gaëtan Carlier Date: Wed, 5 Sep 2012 11:06:15 +0000 (+0200) Subject: ARM : i.MX27 : split code for allocation of ressources of camera and eMMA X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3ab3a350200c14350220fffde893f3afb640fd25;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git ARM : i.MX27 : split code for allocation of ressources of camera and eMMA This is to prepare addition of m2m-emmapp driver otherwise IMX_HAVE_PLATFORM_MX2_CAMERA must be declared even if only Post-Processor is needed. IMX_HAVE_PLATFORM_MX2_EMMA define has been added. Changes since v1: - Add "select IMX_HAVE_PLATFORM_MX2_EMMA" for MACH_IMX27_VISSTRIM_M10 platform due to pending patch in linux-media tree that will call imx27_add_mx2_emmaprp().
