fc1b6ef7bf drm/panel: simple: Fix Innolux G070Y2-L01 BPP settings
The Innolux G070Y2-L01 supports two modes of operation:
1) FRC=Low/NC ... MEDIA_BUS_FMT_RGB666_1X7X3_SPWG ... BPP=6
2) FRC=High ..... MEDIA_BUS_FMT_RGB888_1X7X4_SPWG ... BPP=8

Currently the panel description mixes both, BPP from 1) and bus
format from 2), which triggers a warning at panel-simple.c:615.

Pick the later, set bpp=8, fix the warning.

6061806a86 drm/imx: parallel-display: Remove bus flags check in imx_pd_bridge_atomic_check()
If display timings were read from the devicetree using
of_get_display_timing() and pixelclk-active is defined
there, the flag DISPLAY_FLAGS_SYNC_POSEDGE/NEGEDGE is
automatically generated. Through the function
drm_bus_flags_from_videomode() e.g. called in the
panel-simple driver this flag got into the bus flags,
but then in imx_pd_bridge_atomic_check() the bus flag
check failed and will not initialize the display. The
original commit fe141cedc4 does not explain why this
check was introduced. So remove the bus flags check,
because it stops the initialization of the display with
valid bus flags.

Fixes: fe141cedc4 ("drm/imx: pd: Use bus format/flags provided by the bridge when available")

5df2dc0087 MAINTAINERS: fix ath11k DT bindings location
Commit dae0978d41 ("dt: bindings: net: add qcom,ath11k.yaml") obviously
adds qcom,ath11k.yaml, but the file entry in MAINTAINERS, added with
commit fcda1cb816 ("MAINTAINERS: add DT bindings files for ath10k and

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

Repair this file reference in QUALCOMM ATHEROS ATH11K WIRELESS DRIVER, and
put it in alphabetic order while at it.

3225717f6d RDMA/rxe: Replace red-black trees by xarrays
Currently the rxe driver uses red-black trees to add indices to the rxe
object pools. Linux xarrays provide a better way to implement the same
functionality for indices. This patch replaces red-black trees by xarrays
for pool objects. Since xarrays already have a spinlock use that in place
of the pool rwlock. Make sure that all changes in the xarray(index) and
kref(ref counnt) occur atomically.

====================
MediaTek Ethernet Patches on MT8195

Changes in v13:
1. add reviewed-by in "net: dt-bindings: dwmac: add support for mt8195"
   as Rob's comments.
2. drop num_clks defined in mediatek_dwmac_plat_data struct in "stmmac:
   dwmac-mediatek: Reuse more common features" as Angelo's comments.

Changes in v12:
1. add a new patch "stmmac: dwmac-mediatek: re-arrange clock setting" to
   this series, to simplify clock handling in driver, which benefits to
   binding file mediatek-dwmac.yaml.
2. modify dt-binding description in patch "net: dt-bindings: dwmac: add
   support for mt8195" as Rob's comments in v10 series, put mac_cg to the
   end of clock list.
3. there are small changes in patch "stmmac: dwmac-mediatek: add support
   for mt8195", @AngeloGioacchino, please review it kindly.

Changes in v11:
1. add reivewed-by in "net: dt-bindings: dwmac: Convert mediatek-dwmac to
   DT schema" as Rob's comments.
2. fall back "net: dt-bindings: dwmac: add support for mt8195" to v8 version
   as mentioned in previous reply(https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20211216055328.15953-7-biao.huang@mediatek.com/):
   2.1 there is already a special clock named "rmii_internal", which need to
       be put to the end of the clock list(driver special handling),
       so we can't simply put new "mac_cg" for mt8195 to the end of the clock
       list.
   2.2 we prefer the if-then schema, which will make mt8195 clock list clearer
       with some duplicated information.
   2.3 we expect the future IC will follow mt2712 or mt8195, so we only need
       add new IC name to compatible list for future IC, and will not make the
       clock list binding files worse.

Changes in v10:
1. add detailed description in "arm64: dts: mt2712: update ethernet
   device node" to make the modifications clearer as Matthias's comments.
2. modify dt-binding description as Rob's comments, and "make dtbs_check" runs
   pass locally with "arm64: dts: mt2712: update ethernet device node"
   in this series.

Changes in v9:
1. remove oneOf for 1 entry as Rob's comments.
2. add new clocks to the end of existing clocks to simplify
   the binding as Rob's comments.

Changes in v8:
1. add acked-by in "stmmac: dwmac-mediatek: add platform level clocks
   management" patch

Changes in v7:
1. fix uninitialized warning as Jakub's comments.

Changes in v6:
1. update commit message as Jakub's comments.
2. split mt8195 eth dts patch("arm64: dts: mt8195: add ethernet device
   node") from this series, since mt8195 dtsi/dts basic patches is still
   under reviewing.
   https://patchwork.kernel.org/project/linux-mediatek/list/?series=579071
   we'll resend mt8195 eth dts patch once all the dependent patches are
   accepted.

Changes in v5:
1. remove useless inclusion in dwmac-mediatek.c as Angelo's comments.
2. add acked-by in "net-next: stmmac: dwmac-mediatek: add support for
   mt8195" patch

Changes in v4:
1. add changes in commit message in "net-next: dt-bindings: dwmac:
   Convert mediatek-dwmac to DT schema" patch.
2. remove ethernet-controller.yaml since snps,dwmac.yaml already include it.

Changes in v3:
1. Add prefix "net-next" to support new IC as Denis's suggestion.
2. Split dt-bindings to two patches, one for conversion, and the other for
   new IC.
3. add a new patch to update device node in mt2712-evb.dts to accommodate to
   changes in driver.
4. remove unnecessary wrapper as Angelo's suggestion.
5. Add acked-by in "net-next: stmmac: dwmac-mediatek: Reuse more common
   features" patch.

Changes in v2:
1. fix errors/warnings in mediatek-dwmac.yaml with upgraded dtschema tools

Changes in v1:
This series include 5 patches:
1. add platform level clocks management for dwmac-mediatek
2. resue more common features defined in stmmac_platform.c
3. add ethernet entry for mt8195

79e1177809 arm64: dts: mt2712: update ethernet device node

update ethernet device node in dts to accommodate to it.

1. stmmac_probe_config_dt() in stmmac_platform.c will initialize specified
   parameters according to compatible string "snps,dwmac-4.20a", then,
   dwmac-mediatek.c can skip the initialization if add compatible string
   "snps,dwmac-4.20a" in eth device node.
2. commit 882007ed78 ("net-next: dt-binding: dwmac-mediatek: add more

DRRS operates on transcoder level, so we should only poke at it from
the master crtc rather than letting every joined pipe give it
potentially conflicting input.

1b333c679a drm/i915: Do DRRS disable/enable during pre/post_plane_update()
Let's just do a full DRRS disable/enable across all pipe updates.
This guarantees that the DRRS work doesn't interfere with anything
while the atomic commit is busy reprogramming the pipe.

Needed so that we can start reprogramming M/N seamlessly during
fastsets whenever possible. Also avoids the pre-bdw DRRS PIPECONF
rmw racing with the potential PIPECONF write from the atomic
commit (eg. due to GAMMA_MODE changes).

Make the tracing formatting for user_data and flags consistent.

Having consistent formatting allows one for example to grep for a specific
user_data/flags and be able to trace a single sqe through easily.

Change user_data to 0x%llx and flags to 0x%x everywhere. The '0x' is
useful to disambiguate for example "user_data 100".

Additionally remove the '=' for flags in io_uring_req_failed, again for consistency.

2260e4d8f5 drm/i915: Put the downclock_mode check back into can_enable_drrs()
With static DRRS the user might ask for the lowest possible refresh

downclock mode for it and we should not try to enable seamless DRRS.
This will in fact oops.

We used to check for the presence of the downclock mode here, but
that got removed in commit f0a57798fb ("drm/i915: Introduce
intel_panel_drrs_type()") as redundant (which it was at the time).
But we do need the check again now that static DRRS is a thing.

intel_panel_drrs_type() :/

1c7cea1579 drm/i915: Use drm_mode_copy()
struct drm_display_mode embeds a list head, so overwriting
the full struct with another one will corrupt the list
(if the destination mode is on a list). Use drm_mode_copy()
instead which explicitly preserves the list head of
the destination mode.

Even if we know the destination mode is not on any list
using drm_mode_copy() seems decent as it sets a good
example. Bad examples of not using it might eventually
get copied into code where preserving the list head
actually matters.

Obviously one case not covered here is when the mode
itself is embedded in a larger structure and the whole
structure is copied. But if we are careful when copying
into modes embedded in structures I think we can be a
little more reassured that bogus list heads haven't been
propagated in.

====================
100GbE Intel Wired LAN Driver Updates 2022-03-15

Jacob Keller says:

The ice_sriov.c file now houses almost all of the virtualization code in the
ice driver. This includes both Single Root specific implementation as well
as generic functionality such as the virtchnl interface.

We are planning to implement support for Scalable IOV in the ice driver in
the future. This implementation will want to use the generic functionality
in ice_sriov.c

Rather than dump the Scalable IOV code into ice_sriov.c, we will want to
implement it in a separate file, ice_siov.c

To help with this, refactor the code in ice_sriov.c and split the generic
functionality out into separate files.

Reorganize code to make the non-implementation specific bits into new files
with the following general guidelines:

* ice_vf_lib.[ch]

Basic VF structures and accessors. This is where scheme-independent
code will reside.

* ice_virtchnl.[ch]

Virtchnl message handling. This is where the bulk of the logic for
processing messages from VFs using the virtchnl messaging scheme will
reside. This is separated from ice_vf_lib.c because it is somewhat
distinct and stand alone.

* ice_sriov.[ch]

Single Root IOV implementation, including initialization and the
routines for interacting with SR-IOV based netdev operations.

* (future) ice_siov.[ch]

Scalable IOV implementation.

The end goal is to make it easier to re-use the generic parts of the
virtualization logic while keeping separate the concerns of the Single Root
implementation.

In addition to the pure code moves, this series has a reset refactor which
clean up the functionality to make it easier to reuse the reset code. A new
ops table is introduced to make the VF reset logic more generic. The Single
Root specific details are implemented in ice_sriov.c. A future series
implementing Scalable IOV support will use this ops table to allow re-use of
the reset logic which is now in ice_vf_lib.c

e1bca853dd EDAC/altera: Add SDRAM ECC check for U-Boot
A bug in legacy U-Boot causes a crash during SDRAM boot if ECC is not
enabled in the bitstream but enabled in the Linux config.

Memory mapped read of the ECC Enabled bit was only enabled if U-Boot
determined ECC was enabled in the bitstream.

The Linux driver checks the ECC enable bit using a memory map read.
In the ECC disabled bitstream case, U-Boot didn't enable ECC register
memory map reads and since they are not allowed this results in a crash.

Always read the ECC Enable register through a SMC call which is always
allowed and it works with legacy and current U-Boot.
