2018-11-13mtd: spi-nor: don't drop sfdp data if optional parsers failTudor.Ambarus@microchip.com
JESD216C states that just the Basic Flash Parameter Table is mandatory. Already defined (or future) additional parameter headers and tables are optional. Don't drop already collected sfdp data in case an optional table parser fails. In case of failing, each optional parser is responsible to roll back to the previously known spi_nor data.

2018-11-13qed: Fix rdma_info structure allocationMichal Kalderon
Certain flows need to access the rdma-info structure, for example dcbx update flows. In some cases there can be a race between the allocation or deallocation of the structure which was done in roce start / roce stop and an asynchrounous dcbx event that tries to access the structure. For this reason, we move the allocation of the rdma_info structure to be similar to the iscsi/fcoe info structures which are allocated during device setup. We add a new field of "active" to the struct to define whether roce has already been started or not, and this is checked instead of whether the pointer to the info structure.

First we have a patch by Oliver Hartkopp which changes the raw socket's raw_sendmsg() to return an error value if the user tries to send a CANFD frame to a CAN-2.0 device. The next two patches are by Jimmy Assarsson and fix potential problems in the kvaser_usb driver. YueHaibing's patches for the ucan driver fix a compile time warning and remove a duplicate include. Eugeniu Rosca patch adds more binding documentation to the rcar_can driver bindings. The next two patches are by Fabrizio Castro for the rcar_can driver and fixes a problem in the driver's probe function and document the r8a774a1 binding. Lukas Wunner's patch fixes a recpetion problem in hi311x driver by switching from edge to level triggered interruts. The next three patches all target the flexcan driver. Pankaj Bansal's patch unconditionally unlocks the last mailbox used for RX. Alexander Stein provides a better workaround for a hardware limitation when sending RTR frames, by using the last mailbox for TX, resulting in fewer lost frames. The patch by me simplyfies the driver, by making a runtime value a compile time constant. The following 4 patches are by me and provide the groundwork for the next patches by Oleksij Rempel. To avoid code duplication common code in the common CAN driver infrastructure is factured out and error handling is cleaned up. The next 4 patches are by Oleksij Rempel and fix the problem in the flexcan driver that other processes see TX frames arrive out of order with ragards to a RX'ed frame (which are send by a different system on the CAN bus as the result of our TX frame). ==================== Signed-off-by: David S.

2018-11-13drm/i915: Determine DSI panel orientation from VBTVille Syrjälä
VBT appears to have two (or possibly three) ways to indicate the panel rotation. The first is in the MIPI config block, but that apparenly usually (maybe always?) indicates 0 degrees despite the actual panel orientation. The second way to indicate this is in the general features block, which can just indicate whether 180 degress rotation is used. The third might be a separate rotation data block, but that is not at all documented so who knows what it may contain. Let's try the first two. We first try the DSI specicic VBT information, and it it doesn't look trustworthy (ie. indicates 0 degrees) we fall back to the 180 degree thing. Just to avoid too many changes in one go we shall also keep the hardware readout path for now. If this works for more than just my VLV FFRD the question becomes how many of the panel orientation quirks are now redundant? v2: Move the code into intel_dsi.c (Jani) Cc: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181022142015.4026-1-ville.syrjala@linux.intel.com Tested-by: Hans de Goede <hdegoede@redhat.com>

Let's make sure the DSI port is actually on before we go poking at the plane register to determine which way it's rotated. Otherwise we could be looking at a plane that is feeding a HDMI port for instance. And in order to read the plane register we need the power well to be on. Make sure that is indeed the case.

2018-11-13drm/i915: Always write both TILEOFF and LINOFF plane registersVille Syrjälä
Reduce the clutter in the sprite update functions by writing both TILEOFF and LINOFF registers unconditionally. We already did this for primary planes so might as well do it for the sprites too. There is no harm in writing both registers. Which one gets used depends on the tilimg mode selected in the plane control registers. It might even make sense to clear the register that won't get used. That could make register dumps a little easier to parse. But I'm not sure it's worth the extra hassle.

2018-11-13drm/meson: Add primary plane scalingNeil Armstrong
This patch adds support for the Primary Plane scaling. On the Amlogic GX SoCs, the primary plane is used as On-Screen-Display layer on top of video, and it's needed to keep the OSD layer to a lower size as the physical display size to : - lower the memory bandwidth - lower the OSD rendering - lower the memory usage This use-case is used when setting the display mode to 3840x2160 and the OSD layer is rendered using the GPU. In this case, the GXBB & GXL cannot work on more than 2000x2000 buffer, thus needing the OSD layer to be kept at 1920x1080 and upscaled to 3840x2160 in hardware. The primary plane atomic check still allow 1:1 scaling, allowing native 3840x2160 if needed by user-space applications.

2018-11-13drm/meson: Support Overlay plane for video renderingNeil Armstrong
The Amlogic Meson GX SoCs support an Overlay plane behind the primary plane for video rendering. This Overlay plane support various YUV layouts : - YUYV - NV12 / NV21 - YUV444 / 422 / 420 / 411 / 410 The scaler supports a wide range of scaling ratios, but for simplicity, plane atomic check limits the scaling from x5 to /5 in vertical and horizontal scaling. The z-order is fixed and always behind the primary plane and cannot be changed. The scaling parameter algorithm was taken from the Amlogic vendor kernel code and rewritten to match the atomic universal plane requirements. The video rendering using this overlay plane support has been tested using the new Kodi DRM-KMS Prime rendering path along the in-review V4L2 Mem2Mem Hardware Video Decoder up to 3840x2160 NV12 frames on various display modes.

2018-11-12bnx2x: Assign unique DMAE channel number for FW DMAE transactions.Sudarsana Reddy Kalluru
Driver assigns DMAE channel 0 for FW as part of START_RAMROD command. FW uses this channel for DMAE operations (e.g., TIME_SYNC implementation). Driver also uses the same channel 0 for DMAE operations for some of the PFs (e.g., PF0 on Port0). This could lead to concurrent access to the DMAE channel by FW and driver which is not legal. Hence need to assign unique DMAE id for FW. Currently following DMAE channels are used by the clients, MFW - OCBB/OCSD functionality uses DMAE channel 14/15 Driver 0-3 and 8-11 (for PF dmae operations) 4 and 12 (for stats requests) Assigning unique dmae_id '13' to the FW.

2018-11-12drm/i915: Fix hpd handling for pins with two encodersVille Syrjälä
In my haste to remove irq_port[] I accidentally changed the way we deal with hpd pins that are shared by multiple encoders (DP and HDMI for pre-DDI platforms). Previously we would only handle such pins via ->hpd_pulse(), but now we queue up the hotplug work for the HDMI encoder directly. Worse yet, we now count each hpd twice and this increment the hpd storm count twice as fast. This can lead to spurious storms being detected. Go back to the old way of doing things, ie. delegate to ->hpd_pulse() for any pin which has an encoder with that hook implemented. I don't really like the idea of adding irq_port[] back so let's loop through the encoders first to check if we have an encoder with ->hpd_pulse() for the pin, and then go through all the pins and decided on the correct course of action based on the earlier findings. I have occasionally toyed with the idea of unifying the pre-DDI HDMI and DP encoders into a single encoder as well. Besides the hotplug processing it would have the other benefit of preventing userspace from trying to enable both encoders at the same time. That is simply illegal as they share the same clock/data pins. We have some testcases that will attempt that and thus fail on many older machines. But for now let's stick to fixing just the hotplug code.

2018-11-12drm/i915/execlists: Force write serialisation into context image vs executionChris Wilson
Ensure that the writes into the context image are completed prior to the register mmio to trigger execution. Although previously we were assured by the SDM that all writes are flushed before an uncached memory transaction (our mmio write to submit the context to HW for execution), we have empirical evidence to believe that this is not actually the case.
