media: sun8i-di: Add a Kconfig dependency on RESET_CONTROLLER

2022-09-24T09:21:45Z

The driver relies on the reset controller API to work, so add RESET_CONTROLLER as one of its Kconfig dependencies. Fixes: a4260ea49547 ("media: sun4i: Add H3 deinterlace driver") Signed-off-by: Paul Kocialkowski Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: Kconfig: cleanup VIDEO_DEV dependencies

2022-03-18T04:58:35Z

media Kconfig has two entries associated to V4L API: VIDEO_DEV and VIDEO_V4L2. On Kernel 2.6.x, there were two V4L APIs, each one with its own flag. VIDEO_DEV were meant to: 1) enable Video4Linux and make its Kconfig options to appear; 2) it makes the Kernel build the V4L core. while VIDEO_V4L2 where used to distinguish between drivers that implement the newer API and drivers that implemented the former one. With time, such meaning changed, specially after the removal of all V4L version 1 drivers. At the current implementation, VIDEO_DEV only does (1): it enables the media options related to V4L, that now has: menu "Video4Linux options" visible if VIDEO_DEV source "drivers/media/v4l2-core/Kconfig" endmenu but it doesn't affect anymore the V4L core drivers. The rationale is that the V4L2 core has a "soft" dependency at the I2C bus, and now requires to select a number of other Kconfig options: config VIDEO_V4L2 tristate depends on (I2C || I2C=n) && VIDEO_DEV select RATIONAL select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE default (I2C || I2C=n) && VIDEO_DEV In the past, merging them would be tricky, but it seems that it is now possible to merge those symbols, in order to simplify V4L dependencies. Let's keep VIDEO_DEV, as this one is used on some make *defconfig configurations.

media: platform: sun8i-di: move config to its own file

2022-03-18T04:56:31Z

In order to better organize the platform/Kconfig, place sun8i-di-specific config stuff on a separate Kconfig file. Acked-by: Jernej Skrabec Signed-off-by: Mauro Carvalho Chehab

media: sunxi: Make use of the helper function devm_platform_ioremap_resource()

Use the devm_platform_ioremap_resource() helper instead of calling platform_get_resource() and devm_ioremap_resource() separately Signed-off-by: Cai Huoqing Acked-by: Maxime Ripard Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: sun8i-di: Fix runtime PM imbalance in deinterlace_start_streaming

2021-04-09T10:58:34Z

pm_runtime_get_sync() will increase the runtime PM counter even it returns an error. Thus a pairing decrement is needed to prevent refcount leak. Fix this by replacing this API with pm_runtime_resume_and_get(), which will not change the runtime PM counter on error.

media: sun8i-di: Remove the call to of_dma_configure

of_dma_configure is called by the core before probe gets called so this is redundant. Signed-off-by: Maxime Ripard Reviewed-by: Chen-Yu Tsai Reviewed-by: Christoph Hellwig Acked-by: Hans Verkuil Acked-by: Daniel Vetter

It is spurious to call 'clk_disable_unprepare()' when 'clk_prepare_enable()' has not been called yet. Re-order the error handling path to avoid it.
