2023-09-14media: via: Use correct dependency for camera sensor driversSakari Ailus
The via camera controller driver selected ov7670 driver, however now that driver has dependencies and may no longer be selected unconditionally.

2023-06-19fbdev/media: Use GPIO descriptors for VIA GPIOLinus Walleij
The VIA fbdev exposes a custom GPIO chip for its GPIOs, these are in turn looked up the camera driver using a custom API. Drop the custom API, provide a look-up table and convert to GPIO descriptors. Note proper polarity on the RESET line. Cc: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Helge Deller <deller@gmx.de>
2023-04-12media: Fix indentation issues introduced by subdev-wide state structLaurent Pinchart
Commit 0d346d2a6f54 ("media: v4l2-subdev: add subdev-wide state struct") applied a large media tree-wide change produced by coccinelle. It was so large that a set of identical indentation issues went unnoticed during review. Fix them. While at it, and because it's easy to review both changes together, add a trailing comma for the last (and only) struct member initialization of the related structures, to avoid future changes should new fields need to be initialized.

2023-04-11media: via-camera: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2022-03-18media: Kconfig: cleanup VIDEO_DEV dependenciesMauro Carvalho Chehab
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.
