Moudy Ho	b4e5219985	media: platform: mtk-mdp3: reconfigure shared memory ... For performance and multi-chip support, use dynamic layout instead of statically configured pools. Divide the shared memory into the 3 64-bit aligned layouts listed below: vpu->param_addr -> +-----------------------------------------+ | | | To SCP : Input frame parameters | | (struct img_ipi_frameparam) | | | +-----------------------------------------+ vpu->work_addr -> +-----------------------------------------+ | | | In SCP : Reserve for SCP calculation | | | +-----------------------------------------+ vpu->config_addr -> +-----------------------------------------+ | | | From SCP : Output component config | | (struct img_config) | | | +-----------------------------------------+ Signed-off-by: Moudy Ho <moudy.ho@mediatek.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>	2023-04-11 17:17:46 +02:00
Moudy Ho	61890ccaef	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>	2022-08-30 16:25:51 +02:00
