Some data might be stuck in the DMA pipeline because the application does not tell us how many frames it wants to capture. So there will always be some time delay between the application requesting the last frame it needs and stopping the stream which will stop DMA. Drain that data so it does not corrupt the next frame captured when the stream is re-started later. Marking this as a hack for now because it is not clear yet whether this is a hardware problem or a software problem. If it does turn out to be a hardware problem, it can be presented as a workaround instead. Signed-off-by:
-
The subdevice power needs to be turned on before the stream is started. Otherwise it might not be in the proper state to stream the data. For some reason, it is observer with OV5640 that turning the power off when stopping the stream causes the next stream to freeze infinitely. So leave it on for now until this issue is root caused. Signed-off-by:
-
Add nodes for Cadence CSI2RX, DPHY, and TI's CSI2RX wrapper. Also add nodes for OV5640 which is the camera the drivers have been tested with. Signed-off-by:

The CSI2RX subsystem uses PSI-L DMA to transfer frames to memory. It can have up to 32 threads but the current driver only supports using one. So add an entry for that one thread. Signed-off-by:
-
TI's J721E uses the Cadence CSI2RX and DPHY peripherals to facilitate capture over a CSI-2 bus. The Cadence CSI2RX IP acts as a bridge between the TI specific parts and the CSI-2 protocol parts. TI then has a wrapper on top of this bridge called the SHIM layer. It takes in data from stream 0, repacks it, and sends it to memory over PSI-L DMA. This driver acts as the "front end" to V4L2 client applications. It implements the required ioctls and buffer operations, passes the necessary calls on to the bridge, programs the SHIM layer, and performs DMA via the dmaengine API to finally return the data to a buffer supplied by the application.

TI's J721E uses the Cadence CSI2RX and DPHY peripherals to facilitate capture over a CSI-2 bus. The TI CSI2RX platform driver glues all the parts together. Signed-off-by:
-
When this bridge driver is being user by another platform driver, it might want to call subdev operations like getting format, setting format, enumerating format codes, etc. Add wrapper functions that pass that call through to the sensor. Currently wrappers are added only for the ops used by TI's platform driver. More can be added later as needed. Signed-off-by:
-
Firstly, there is no VC_EN bit present in the STREAM_DATA_CFG register. Bit 31 is part of the VL_SELECT field. Remove it completely. Secondly, it makes little sense to enable ith virtual channel for ith stream. Sure, there might be a use-case that demands it. But there might also be a use case that demands all streams to use the 0th virtual channel. Prefer this case over the former because it is less arbitrary and also makes it very clear what the limitations of the current driver is instead of giving a false impression that multiple virtual channels are supported. Signed-off-by:
-
The stream stop procedure says that the STOP bit should be set when the stream is to be stopped, and then the ready bit in stream status register polled to make sure the STOP operation is finished. Signed-off-by:
-
This resets the stream state machines and FIFOs, giving them a clean slate. On J721E if the streams are not reset before starting the capture, the captured frame gets wrapped around vertically on every run after the first. Signed-off-by:
-
Some platforms like TI's J721E can have the CSI2RX paired with an external DPHY. Add support to enable and configure the DPHY using the generic PHY framework. Get the pixel rate and bpp from the subdev and pass them on to the DPHY along with the number of lanes. All other settings are left to their default values. Signed-off-by:
-
The Cadence DPHY can be used to receive image data over the CSI-2 protocol. Add support for Rx mode. The programming sequence differs from the Tx mode so it is added as a separate set of hooks to isolate the two paths. The PHY is in Tx mode by default and it needs to be set in Rx mode by setting the submode to PHY_MIPI_DPHY_SUBMODE_RX in the set_mode() callback. Signed-off-by:
-
Allow callers to set the PHY mode. The main mode should always be PHY_MODE_MIPI_DPHY but the submode can either be PHY_MIPI_DPHY_SUBMODE_RX or PHY_MIPI_DPHY_SUBMODE_TX. Update the ops based on the requested submode. Signed-off-by:
-
The Rx programming sequence differs from the Tx programming sequence. Currently only Tx mode is supported. Move all the Tx related parts into a set of Tx-specific hooks that are then called by the main PHY framework hooks. This way when Rx support is added all that is needed to be done is to plug in the Rx hooks. The clocks "psm" and "pll_ref" are not used by the Rx path so make them optional in the probe and then check if they exist in the power_on() hook. Signed-off-by:
-
Convert Cadence DPHY binding to YAML. While here, make the clocks optional and add an optional "power-domains" property. Signed-off-by:
-
As some D-PHY controllers support both Rx and Tx mode, we need a way for users to explicitly request one or the other. For instance, Rx mode can be used along with MIPI CSI-2 while Tx mode can be used with MIPI DSI. Introduce new MIPI D-PHY PHY submodes to use with PHY_MODE_MIPI_DPHY. The default (zero value) is kept to Tx so only the rkisp1 driver, which uses D-PHY in Rx mode, needs to be adapted. Signed-off-by:

This patch add MQPRIO Qdisk offload in full 'channel' mode which allows not only setup pro:tc mapping, but also configure TX shapers on external port fifos. The K3 CPSW MQPRIO Qdisk offload is expected to work with VALN/priority tagged packets and not-tagged packets have to be mapped only to TC0. - TX traffic classes must be rated starting from TC that has highest priority and with no gaps - Traffic classes are used starting from 0, that has highest priority - min_rate defines Committed Information Rate (guaranteed) - max_rate defines Excess Information Rate (non guaranteed) and offloaded as (max_rate[i] - tcX_min_rate[i]) - VALN/priority tagged packets mapped to TC0 will exit switch with VALN tag priority 0 The configuration example: ethtool -L eth1 tx 5 ethtool --set-priv-flags eth1 p0-rx-ptype-rrobin off tc qdisc add dev eth1 parent root handle 100: mqprio num_tc 3 \ map 0 0 1 2 0 0 0 0 0 0 0 0 0 0 0 0 \ queues 1@0 1@1 1@2 h...

This patch allows to rate limit TX queues (DMA) for cpsw interface by configuring the rate in absolute Mb/s units per TX queue. Example: ethtool -L eth0 tx 4 echo 100 > /sys/class/net/eth0/queues/tx-0/tx_maxrate echo 200 > /sys/class/net/eth0/queues/tx-1/tx_maxrate echo 50 > /sys/class/net/eth0/queues/tx-2/tx_maxrate echo 30 > /sys/class/net/eth0/queues/tx-3/tx_maxrate Signed-off-by: -
By default the tagged ingress packets to the switch from P0 got internal switch priority assigned equal to the DMA CPPI channel number they came from unless CPSW_P0_CONTROL_REG.RX_REMAP_VLAN. it causes issues with applying QoS policies and mapping packets on external port fifos, because the default configuration is vlan_aware and DMA CPPI channels are shared between all external ports. Hence enable CPSW_P0_CONTROL_REG.RX_REMAP_VLAN so packet will preserve internal switch priority assigned following the VLAN(priority) tag no matter through which DMA CPPI Channels packets enter the switch.

bcdma_get_*() and udma_get_*() checks if bchan/rchan/tchan/rflow is already allocated by checking if it has a NON NULL value. For the error cases, bchan/rchan/tchan/rflow will have error value and bcdma_get_*() and udma_get_*() considers this as already allocated (PASS) since the error values are NON NULL. This results in NULL pointer dereference error while de-referencing bchan/rchan/tchan/rflow. Reset the value of bchan/rchan/tchan/rflow to NULL if the allocation actually fails.
