Hi, This series adds support for CSI2 capture on J721E. It includes some fixes to the Cadence CSI2RX driver, adds runtime PM support to OV5640 driver, and finally adds the TI CSI2RX wrapper driver. This series used to include the DPHY and DMA engine patches as well, but they have been split off to facilitate easier merging. Patch 3 is build-dependent on the DPHY series [0]. The DMA engine patch [1] can go in any order since that is only a run time dependency. Things probably won't work without it but it will still build fine. Tested on TI's J721E with OV5640 sensor.

It might go idle because of a lack of buffers. This state can be used to restart it if needed. - Do not include the current buffer in the pending queue. It is slightly better modelling than leaving it at the head of the pending queue. - Use the buffer as the callback argument, and add a reference to csi in it. - If queueing a buffer to DMA fails, the buffer gets leaked and DMA gets stalled with. Instead, report the error to vb2 and queue the next buffer in the pending queue. - DMA gets stalled if we run out of buffers since the callback is the only one that fires subsequent transfers and it is no longer being called. Check for that when queueing buffers and restart DMA if needed. - Do not put of node until we are done using the fwnode. - Set inital format to UYVY 640x480. - Add compatible: contains: const: cdns,csi2rx to allow SoC specific compatible. - Add more constraints for data-lanes property. Changes in v2: - Use phy_pm_runtime_get_sync() and phy_pm_runtime_put() before making calls to set PHY mode, etc. to make sure it is ready. - Use dmaengine_get_dma_device() instead of directly accessing dma->device->dev. - Do not set dst_addr_width when configuring slave DMA. - Move to a separate subdir and rename to j721e-csi2rx.c - Convert compatible to ti,j721e-csi2rx. - Move to use Media Controller centric APIs. - Improve cleanup in probe when one of the steps fails. - Add colorspace to formats database. - Set hw_revision on media_device. - Move video device initialization to probe time instead of register time. - Rename to ti,j721e-csi2rx.yaml - Add an entry in MAINTAINERS. - Add a description for the binding. - Change compatible to ti,j721e-csi2rx to make it SoC specific. - Remove description from dmas, reg, power-domains. - Remove a limit of 2 from #address-cells and #size-cells. - Fix add ^ to csi-bridge subnode regex. - Make ranges mandatory. - Add unit address in example. - Add a reference to cdns,csi2rx in csi-bridge subnode. - Expand the example to include the csi-bridge subnode as well. - Re-order subject prefixes. - Convert OV5640 to use runtime PM and drop Cadence CSI2RX s_power patch. - Drop subdev call wrappers from cdns-csi2rx. - Move VPE and CAL to a separate subdir. - Rename ti-csi2rx.c to j721e-csi2rx.c Pratyush Yadav (11): media: ov5640: Use runtime PM to control sensor power media: cadence: csi2rx: Unregister v4l2 async notifier media: cadence: csi2rx: Add external DPHY support media: cadence: csi2rx: Soft reset the streams before starting capture media: cadence: csi2rx: Set the STOP bit when stopping a stream media: cadence: csi2rx: Fix stream data configuration media: cadence: csi2rx: Populate subdev devnode media: Re-structure TI platform drivers media: ti: Add CSI2RX support for J721E media: dt-bindings: Add DT bindings for TI J721E CSI2RX driver media: dt-bindings: Convert Cadence CSI2RX binding to YAML .../devicetree/bindings/media/cdns,csi2rx.txt | 100 -- .../bindings/media/cdns,csi2rx.yaml | 169 +++ .../bindings/media/ti,j721e-csi2rx.yaml | 101 ++ MAINTAINERS | 10 +- drivers/media/i2c/Kconfig | 2 +- drivers/media/i2c/ov5640.c | 127 ++- drivers/media/platform/Kconfig | 12 + drivers/media/platform/Makefile | 2 +- drivers/media/platform/cadence/cdns-csi2rx.c | 189 +++- drivers/media/platform/ti/Makefile | 4 + drivers/media/platform/ti/cal/Makefile | 3 + .../{ti-vpe => ti/cal}/cal-camerarx.c | 0 .../platform/{ti-vpe => ti/cal}/cal-video.c | 0 .../media/platform/{ti-vpe => ti/cal}/cal.c | 0 .../media/platform/{ti-vpe => ti/cal}/cal.h | 0 .../platform/{ti-vpe => ti/cal}/cal_regs.h | 0 .../media/platform/ti/j721e-csi2rx/Makefile | 2 + .../platform/ti/j721e-csi2rx/j721e-csi2rx.c | 978 ++++++++++++++++++ .../platform/{ti-vpe => ti/vpe}/Makefile | 4 - .../media/platform/{ti-vpe => ti/vpe}/csc.c | 0 .../media/platform/{ti-vpe => ti/vpe}/csc.h | 0 .../media/platform/{ti-vpe => ti/vpe}/sc.c | 0 .../media/platform/{ti-vpe => ti/vpe}/sc.h | 0 .../platform/{ti-vpe => ti/vpe}/sc_coeff.h | 0 .../media/platform/{ti-vpe => ti/vpe}/vpdma.c | 0 .../media/platform/{ti-vpe => ti/vpe}/vpdma.h | 0 .../platform/{ti-vpe => ti/vpe}/vpdma_priv.h | 0 .../media/platform/{ti-vpe => ti/vpe}/vpe.c | 0 .../platform/{ti-vpe => ti/vpe}/vpe_regs.h | 0 29 files changed, 1533 insertions(+), 170 deletions(-) delete mode 100644 Documentation/devicetree/bindings/media/cdns,csi2rx.txt create mode 100644 Documentation/devicetree/bindings/media/cdns,csi2rx.yaml create mode 100644 Documentation/devicetree/bindings/media/ti,j721e-csi2rx.yaml create mode 100644 drivers/media/platform/ti/Makefile create mode 100644 drivers/media/platform/ti/cal/Makefile rename drivers/media/platform/{ti-vpe => ti/cal}/cal-camerarx.c (100%) rename drivers/media/platform/{ti-vpe => ti/cal}/cal-video.c (100%) rename drivers/media/platform/{ti-vpe => ti/cal}/cal.c (100%) rename drivers/media/platform/{ti-vpe => ti/cal}/cal.h (100%) rename drivers/media/platform/{ti-vpe => ti/cal}/cal_regs.h (100%) create mode 100644 drivers/media/platform/ti/j721e-csi2rx/Makefile create mode 100644 drivers/media/platform/ti/j721e-csi2rx/j721e-csi2rx.c rename drivers/media/platform/{ti-vpe => ti/vpe}/Makefile (78%) rename drivers/media/platform/{ti-vpe => ti/vpe}/csc.c (100%) rename drivers/media/platform/{ti-vpe => ti/vpe}/csc.h (100%) rename drivers/media/platform/{ti-vpe => ti/vpe}/sc.c (100%) rename drivers/media/platform/{ti-vpe => ti/vpe}/sc.h (100%) rename drivers/media/platform/{ti-vpe => ti/vpe}/sc_coeff.h (100%) rename drivers/media/platform/{ti-vpe => ti/vpe}/vpdma.c (100%) rename drivers/media/platform/{ti-vpe => ti/vpe}/vpdma.h (100%) rename drivers/media/platform/{ti-vpe => ti/vpe}/vpdma_priv.h (100%) rename drivers/media/platform/{ti-vpe => ti/vpe}/vpe.c (100%) rename drivers/media/platform/{ti-vpe => ti/vpe}/vpe_regs.h (100%) -- 2.30.0
