media: platform: mtk-mdp3: add support for parallel pipe to improve FPS In some chips, MDP3 has the ability to utilize two pipelines to parallelly process a single frame. To enable this feature, multiple CMDQ clients and packets need to be configured at the same time.

media: platform: mtk-mdp3: Add missing check and free for ida_alloc Add the check for the return value of the ida_alloc in order to avoid NULL pointer dereference. Moreover, free allocated "ctx->id" if mdp_m2m_open fails later in order to avoid memory leak.

media: platform: mtk-mdp3: add MediaTek MDP3 driver This patch adds driver for MediaTek's Media Data Path ver.3 (MDP3). It provides the following functions: color transform, format conversion, resize, crop, rotate, flip and additional image quality enhancement. The MDP3 driver is mainly used for Google Chromebook products to import the new architecture to set the HW settings as shown below: User -> V4L2 framework -> MDP3 driver -> SCP (setting calculations) -> MDP3 driver -> CMDQ (GCE driver) -> HW Each modules' related operation control is sited in mtk-mdp3-comp.c Each modules' register table is defined in file with "mdp_reg_" prefix GCE related API, operation control sited in mtk-mdp3-cmdq.c V4L2 m2m device functions are implemented in mtk-mdp3-m2m.c Probe, power, suspend/resume, system level functions are defined in mtk-mdp3-core.c [hverkuil: add 'depends on REMOTEPROC'] Signed-off-by: Ping-Hsun Wu <ping-hsun.wu@mediatek.com> Signed-off-by: daoyuan huang <daoyuan.huang@mediatek.com> Signed-off-by: Moudy Ho <moudy.ho@mediatek.com> Tested-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
