From 9958d30f38b96fb763a10d44d18ddad39127d5f4 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 13 Mar 2022 07:25:46 +0100 Subject: media: Kconfig: cleanup VIDEO_DEV dependencies MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
