media: sun4i-csi: Add a Kconfig dependency on RESET_CONTROLLER

2022-09-24T09:21:44Z

The driver relies on the reset controller API to work, so add RESET_CONTROLLER as one of its Kconfig dependencies. Fixes: 577bbf23b758 ("media: sunxi: Add A10 CSI driver") Signed-off-by: Paul Kocialkowski Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l: ioctl: Set bus_info in v4l_querycap()

2022-04-24T07:07:08Z

The bus_info field is set by most drivers based on the type of the device bus as well as the name of the device. Do this in v4l_querycap() so drivers don't need to. This keeps compatibility with non-default and silly bus_info. Signed-off-by: Sakari Ailus Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

Set bus_info field based on struct device in media_device_init() and remove corresponding code from drivers. Also update media_device_init() documentation: the dev field must be now initialised before calling it. Signed-off-by: Sakari Ailus Reviewed-by: Laurent Pinchart 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: move platform menu dependencies to drivers

2022-03-14T08:42:59Z

Right now, platform dependencies are organized by the type of the platform driver. Yet, things tend to become very messy with time. The better seems to organize the drivers per manufacturer, as other Kernel subsystems are doing. As a preparation for such purpose, get rid of menuconfigs, moving the per-menu dependencies to be at the driver-specifig config entires. This shoud give flexibility to reorganize the platform drivers per manufacturer and re-sort them. This patch removes all "if..endif" options from the platform Kconfig, converting them into depends on. Acked-by: Jernej Skrabec Signed-off-by: Mauro Carvalho Chehab
