2020-12-07media: doc: pixfmt-yuv: Move all luma-only YUV formats to common fileLaurent Pinchart
Luma-only pixel formats are documented in separate files. This duplicates information, as those formats share comon traits. Consolidate them in a single file and describe them in a single table.

2020-12-07media: doc: pixfmt-packed-yuv: Express 4:4:4 formats in a more compact wayLaurent Pinchart
The 4:4:4 packed YUV formats are documented with a bit-level representation, which creates a wide table. Switch to a byte-oriented representation to make it more compact. This prepares for the addition of formats with more than 8 bits per component, that would make the table way too wide.

2020-12-07media: doc: pixfmt-yuv: Move all packed YUV formats to common fileLaurent Pinchart
The pixfmt-packed-yuv.rst file documents packed YUV 4:4:4 formats, but is titled generically as "Packed YUV formats". 4:2:2 and 4:1:1 packed YUV formats are documented in separate files, which can be confusing.

2020-12-07media: doc: pixfmt-rgb: Clarify naming scheme for RGB formatsLaurent Pinchart
The naming scheme for the RGB pixel formats has been developed organically, and isn't consistent between formats using less than 8 bits per pixels (mostly stored in 1 or 2 bytes per pixel, except for RGB666 that uses 4 bytes per pixel) and formats with 8 bits per pixel (stored in 3 or 4 bytes). For the latter category, the names use a components order convention that is the opposite of the first category, and the opposite of DRM pixel formats. This has led to lots of confusion in the past, and would really benefit from being explained more precisely. Do so, which also prepares for the addition of additional RGB pixels formats.

2020-12-07macintosh/adb-iop: Send correct poll commandFinn Thain
The behaviour of the IOP firmware is not well documented but we do know that IOP message reply data can be used to issue new ADB commands. Use the message reply to better control autopoll behaviour by sending a Talk Register 0 command after every ADB response, not unlike the algorithm in the via-macii driver. This poll command is addressed to that device which last received a Talk command (explicit or otherwise).

2020-12-07macintosh/adb-iop: Always wait for reply message from IOPFinn Thain
A recent patch incorrectly altered the adb-iop state machine behaviour and introduced a regression that can appear intermittently as a malfunctioning ADB input device. This seems to be caused when reply packets from different ADB commands become mixed up, especially during the adb bus scan. Fix this by unconditionally entering the awaiting_reply state after sending an explicit command, even when the ADB command won't generate a reply from the ADB device. It turns out that the IOP always generates reply messages, even when the ADB command does not produce a reply packet (e.g. ADB Listen command). So it's not really the ADB reply packets that are being mixed up, it's the IOP messages that enclose them. The bug goes like this: 1. CPU sends a message to the IOP, expecting no response because this message contains an ADB Listen command. The ADB command is now considered complete. 2. CPU sends a second message to the IOP, this time expecting a response because this message contains an ADB Talk command. This ADB command needs a reply before it can be completed. 3. adb-iop driver receives an IOP message and assumes that it relates to the Talk command. It's actually an empty one (with flags == ADB_IOP_EXPLICIT|ADB_IOP_TIMEOUT) for the previous command. The Talk command is now considered complete but it gets the wrong reply data. 4. adb-iop driver gets another IOP response message, which contains the actual reply data for the Talk command, but this is dropped (the driver is no longer in awaiting_reply state).

hclge_dbg_reg_info[] is defined as an array of packed structure accidentally. However, this array contains pointers, which are no longer aligned naturally, and cannot be relocated on PPC64. Hence, when compile-testing this driver on PPC64 with CONFIG_RELOCATABLE=y (e.g. PowerPC allyesconfig), there will be some warnings. Since each field in structure hclge_qos_pri_map_cmd and hclge_dbg_bitmap_cmd is type u8, the pragma packed is unnecessary for these two structures as well, so remove the pragma packed in hclge_debugfs.h to fix this issue, and this increases hclge_dbg_reg_info[] by 4 bytes per entry.

Raydium device does not like splitting of tx transactions into multiple messages - one for the register address and one for the actual data. This results in incorrect behavior on the device side. This change updates raydium_i2c_read and raydium_i2c_write to create i2c_msg arrays separately and passes those arrays into raydium_i2c_xfer which decides based on the address whether the bank switch command should be sent. The bank switch header is still added by raydium_i2c_read and raydium_i2c_write to ensure that all these operations are performed as part of a single I2C transfer. It guarantees that no other transactions are initiated to any other device on the same bus after the bank switch command is sent.

2020-12-06mlxsw: spectrum_router: Reduce mlxsw_sp_ipip_fib_entry_op_gre4()Jiri Pirko
Turned out that mlxsw_sp_ipip_fib_entry_op_gre4() does not need to figure out the IP address and virtual router id. Those are exactly the same as in the fib_entry it is called for. So just use that and reduce mlxsw_sp_ipip_fib_entry_op_gre4() function to only call mlxsw_sp_ipip_fib_entry_op_gre4_rtdp() make the ipip decap op code similar to nve.

2020-12-06mlxsw: spectrum: Bump minimum FW version to xx.2008.2018Petr Machata
The indicated version fixes an issue whereby the MOMTE register would by default enable mirroring of ECN-marked traffic from all traffic classes, once the ECN mirroring was configured. This fix is necessary for offload of RED "ecn_mark" qevent. Signed-off-by: Petr Machata <petrm@nvidia.com> Signed-off-by: Ido Schimmel <idosch@nvidia.com> Signed-off-by: David S.

2020-12-06mlxsw: core: Trace EMAD eventsIdo Schimmel
Currently, mlxsw triggers the 'devlink:devlink_hwmsg' tracepoint whenever a request is sent to the device and whenever a response is received from it. However, the tracepoint is not triggered when an event (e.g., port up / down) is received from the device. Also trace EMAD events in order to log a more complete picture of all the exchanged hardware messages. Signed-off-by: Ido Schimmel <idosch@nvidia.com> Signed-off-by: David S.

2020-12-06selftests: mlxsw: Test RIF's reference count when joining a LAGIdo Schimmel
Test that the reference count of a router interface (RIF) configured for a LAG is incremented / decremented when ports join / leave the LAG. Use the offload indication on routes configured on the RIF to understand if it was created / destroyed. The test fails without the previous patch.
