Those streams are basically the interfaces\nto the video grabbers that will perform the capture.\n\nIt is able to map streams to both CSI datatypes and virtual channels,\ndynamically. This is unclear at this point what the right way to\nsupport it would be, so the driver only uses a static mapping between\nthe virtual channels and streams, and ignores the data types.\n\nThis serie depends on the version 14 of the serie \"Unified fwnode\nendpoint parser, async sub-device notifier support, N9 flash DTS\" by\nSakari Ailus\n\nLet me know what you think!\nMaxime\n\nChanges from v3:\n - Removed stale printk\n - Propagate start/stop functions error code to s_stream\n - Renamed the DT bindings files\n - Clarified the output ports wording in the DT binding doc\n - Added a define for the maximum number of lanes\n - Rebased on top of Sakari's serie\n - Gathered tags based on the reviews\n\nChanges from v2:\n - Added reference counting for the controller initialisation\n - Fixed checkpatch warnings\n - Moved the sensor initialisation after the DPHY configuration\n - Renamed the sensor fields to source for consistency\n - Defined some variables\n - Renamed a few structures variables\n - Added internal and external phy errors messages\n - Reworked the binding slighty by making the external D-PHY optional\n - Moved the notifier registration in the probe function\n - Removed some clocks that are not system clocks\n - Added clocks enabling where needed\n - Added the code to remap the data lanes\n - Changed the memory allocator for the non-devm function, and a\n comment explaining why\n - Reworked the binding wording\n\nChanges from v1:\n - Amended the DT bindings as suggested by Rob\n - Rebase on top of 4.13-rc1 and latest Niklas' serie iteration\n\nMaxime Ripard (2):\n dt-bindings: media: Add Cadence MIPI-CSI2 RX Device Tree bindings\n v4l: cadence: Add Cadence MIPI-CSI2 RX driver\n\n .../devicetree/bindings/media/cdns,csi2rx.txt | 97 ++++\n drivers/media/platform/Kconfig | 1 +\n drivers/media/platform/Makefile | 2 +\n drivers/media/platform/cadence/Kconfig | 12 +\n drivers/media/platform/cadence/Makefile | 1 +\n drivers/media/platform/cadence/cdns-csi2rx.c | 486 +++++++++++++++++++++\n 6 files changed, 599 insertions(+)\n create mode 100644 Documentation/devicetree/bindings/media/cdns,csi2rx.txt\n create mode 100644 drivers/media/platform/cadence/Kconfig\n create mode 100644 drivers/media/platform/cadence/Makefile\n create mode 100644 drivers/media/platform/cadence/cdns-csi2rx.c" }
