Merge tag 'arm-boardfile-remove-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC boardfile updates from Arnd Bergmann
"Unused boardfile removal for 6.3
This is a follow-up to the deprecation of most of the old-style board
files that was merged in linux-6.0, removing them for good.
This branch is almost exclusively dead code removal based on those
annotations. Some device driver removals went through separate
subsystem trees, but the majority is in the same branch, in order to
better handle dependencies between the patches and avoid breaking
bisection.
Unfortunately that leads to merge conflicts against other changes in
the subsystem trees, but they should all be trivial to resolve by
removing the files.
See commit 7d0d3fa7339e ("Merge tag 'arm-boardfiles-6.0' of
git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the
description of which machines were marked unused and are now removed.
The only removals that got postponed are Terastation WXL (mv78xx0) and
Jornada720 (StrongARM1100), which turned out to still have potential
users"

SPDX-License-Identifier: GPL-2.0 - -The VPBE V4L2 driver design -=========================== - -Functional partitioning ------------------------ - -Consists of the following: - - 1. V4L2 display driver - - Implements creation of video2 and video3 device nodes and - provides v4l2 device interface to manage VID0 and VID1 layers. - - 2. Display controller - - Loads up VENC, OSD and external encoders such as ths8200. It provides - a set of API calls to V4L2 drivers to set the output/standards - in the VENC or external sub devices. It also provides - a device object to access the services from OSD subdevice - using sub device ops. The connection of external encoders to VENC LCD - controller port is done at init time based on default output and standard - selection or at run time when application change the output through - V4L2 IOCTLs. - - When connected to an external encoder, vpbe controller is also responsible - for setting up the interface between VENC and external encoders based on - board specific settings (specified in board-xxx-evm.c). This allows - interfacing external encoders such as ths8200. The setup_if_config() - is implemented for this as well as configure_venc() (part of the next patch) - API to set timings in VENC for a specific display resolution. As of this - patch series, the interconnection and enabling and setting of the external - encoders is not present, and would be a part of the next patch series. - - 3. VENC subdevice module - - Responsible for setting outputs provided through internal DACs and also - setting timings at LCD controller port when external encoders are connected - at the port or LCD panel timings required. When external encoder/LCD panel - is connected, the timings for a specific standard/preset is retrieved from - the board specific table and the values are used to set the timings in - venc using non-standard timing mode. - - Support LCD Panel displays using the VENC. For example to support a Logic - PD display, it requires setting up the LCD controller port with a set of - timings for the resolution supported and setting the dot clock. So we could - add the available outputs as a board specific entry (i.e add the "LogicPD" - output name to board-xxx-evm.c). A table of timings for various LCDs - supported can be maintained in the board specific setup file to support - various LCD displays.As of this patch a basic driver is present, and this - support for external encoders and displays forms a part of the next - patch series. - - 4. OSD module - - OSD module implements all OSD layer management and hardware specific - features. The VPBE module interacts with the OSD for enabling and - disabling appropriate features of the OSD. - -Current status --------------- - -A fully functional working version of the V4L2 driver is available. This -driver has been tested with NTSC and PAL standards and buffer streaming. diff --git a/Documentation/admin-guide/media/platform-cardlist.rst b/Documentation/admin-guide/media/platform-cardlist.rst index ac73c4166d1e..8ef57cd13dec 100644 --- a/Documentation/admin-guide/media/platform-cardlist.rst +++ b/Documentation/admin-guide/media/platform-cardlist.rst @@ -73,7 +73,6 @@ via-camera VIAFB camera controller video-mux Video Multiplexer vpif_display TI DaVinci VPIF V4L2-Display vpif_capture TI DaVinci VPIF video capture -vpss TI DaVinci VPBE V4L2-Display vsp1 Renesas VSP1 Video Processing Engine xilinx-tpg Xilinx Video Test Pattern Generator xilinx-video Xilinx Video IP (EXPERIMENTAL) diff --git a/Documentation/admin-guide/media/v4l-drivers.rst b/Documentation/admin-guide/media/v4l-drivers.rst index 90a026ee05c6..734e18c310bd 100644 --- a/Documentation/admin-guide/media/v4l-drivers.rst +++ b/Documentation/admin-guide/media/v4l-drivers.rst @@ -13,7 +13,6 @@ Video4Linux (V4L) driver-specific documentation cafe_ccic cpia2 cx88 - davinci-vpbe fimc imx imx7 |
