media: mediatek: vcodec: Drop platform_get_resource(IORESOURCE_IRQ)

2022-09-27T08:24:44Z

Commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT core") removed support for calling platform_get_resource(..., IORESOURCE_IRQ, ...) on DT-based drivers, but the probe() function of mtk-vcodec's encoder was still making use of it. This caused the encoder driver to fail probe. Since the platform_get_resource() call was only being used to check for the presence of the interrupt (its returned resource wasn't even used) and platform_get_irq() was already being used to get the IRQ, simply drop the use of platform_get_resource(IORESOURCE_IRQ) and handle the failure of platform_get_irq(), to get the driver probing again.

media: platform: mtk-mdp3: fix PM reference leak in mdp_comp_clock_on()

2022-09-24T06:53:43Z

mdp_comp_clock_on will increase runtime PM usage counter, and mdp_comp_clock_off will decrease the runtime PM usage counter. so, if mdp_comp_clock_on failed after increment runtime PM usage counter, it should decrease it before return a error code. pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in reference leak here. Fix it by replacing it with pm_runtime_resume_and_get to keep usage counter balanced. And if failed to enable clk, add pm_runtime_put() to decrease the runtime PM usage counter.

media: platform: mtk-mdp3: add MediaTek MDP3 driver

2022-08-30T14:25:51Z

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 Signed-off-by: daoyuan huang Signed-off-by: Moudy Ho Tested-by: AngeloGioacchino Del Regno Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
