Not all panels in panel-simple were marked what type of panel they
were. I searched through ARM/ARM64 Chromebooks or Chromebook-related
reference boards that I was aware of and found some panels that needed
to be moved. I also skimmed for panels that had no mode and were "big"
since it's quite rare to see a small eDP panel. Here's what I found:
* auo,b101ean01 - rk3288-veyron-minnie
* auo,b133htn01 - exynos5800-peach-pi
* auo,b133xtn01 - tegra124-nyan-big
* boe,nv101wxmn51 - rk3399-gru-bob
* innolux,p120zdg-bf1 - sdm845-cheza
* lg,lp079qx1-sp0v - rk3399-evb and similar
* lg,lp097qx1-spa1 - According to commit 0355dde26e52 ("drm/panel:
simple: Add support for LG LP097QX1-SPA1 panel") this is an eDP
panel.
* lg,lp129qe - tegra124-venice2
* samsung,lsn122dl01-c01 - According to commit 0330eaf39082
("drm/panel: simple: Add support for Samsung LSN122DL01-C01 panel")
this is an eDP panel.
* samsung,ltn140at29-301 - tegra124-nyan-blaze
* sharp,ld-d5116z01b - According to commit cd5e1cbe1f0a ("drm/panel:
simple: Add support for Sharp LD-D5116Z01B panel") this is an eDP
panel.
* sharp,lq123p1jx31 - rk3399-gru-kevin
* starry,kr122ea0sra - rk3399-gru-gru (reference board, not upstream)
I won't promise that I didn't miss a single panel, but that's fairly
complete I think.
I'm not sure the full impact of the fact that they didn't have the
connector type specified, but at least as of commit 9f069c6fbc72
("drm/panel: panel-simple: add default connector_type") we may have
been accidentally thinking of them as DPI panels. We also would
certainly have had a warning. In any case since we don't want to
support anything eDP in the old simple-panel driver, we should move
these.

The panel-simple driver handles way too much. Let's start trying to
get a handle on it by splitting out the eDP panels. This patch does
this:
1. Start by copying simple-panel verbatim over to a new driver,
simple-panel-edp.
2. Rename "panel_simple" to "panel_edp" in the new driver.
3. Keep only panels marked with `DRM_MODE_CONNECTOR_eDP` in the new
driver. Remove those panels from the old driver.
4. Remove all recent "DP AUX bus" stuff from the old driver. The DP
AUX bus is only possible on DP panels.
5. Remove all DSI / MIPI related functions from the new driver.
6. Remove bus_format / bus_flags from eDP driver. These things don't
seem to make any sense for eDP panels so let's stop filling in made
up stuff.
In the end we end up with a bunch of duplicated code for now. Future
patches will try to address _some_ of this duplicated code though some
of it will be unavoidable.
NOTE: This may not actually move all eDP panels over to the new driver
since not all panels were properly marked with
`DRM_MODE_CONNECTOR_eDP`. A future patch will attempt to move wayward
panels I could identify but even so there may be some missed.

In the patch ("drm/edid: Allow the querying/working with the panel ID
from the EDID") we introduced a different way of working with the
panel ID stored in the EDID. Let's use this new way for the quirks
code.
Advantages of the new style:
* Smaller data structure size. Saves 4 bytes per panel.
* Iterate through quirks structure with just "==" instead of strncmp()
* In-kernel storage is more similar to what's stored in the EDID
itself making it easier to grok that they are referring to the same
value.

EDIDs have 32-bits worth of data which is intended to be used to
uniquely identify the make/model of a panel. This has historically
been used only internally in the EDID processing code to identify
quirks with panels.
We'd like to use this panel ID in panel drivers to identify which
panel is hooked up and from that information figure out power sequence
timings. Let's expose this information from the EDID code and also
allow it to be accessed early, before a connector has been created.
To make matching in the panel drivers code easier, we'll return the
panel ID as a 32-bit value. We'll provide some functions for
converting this value back and forth to something more human readable.

eDP panels generally contain almost everything needed to control them
in their EDID. This comes from their DP heritage were a computer needs
to be able to properly control pretty much any DP display that's
plugged into it.
The one big issue with eDP panels and the reason that we need a panel
driver for them is that the power sequencing can be different per
panel.
While it is true that eDP panel sequencing can be arbitrarily complex,
in practice it turns out that many eDP panels are compatible with just
some slightly different delays. See the contents of the bindings file
introduced in this patch for some details.
The fact that eDP panels are 99% probable and that the power
sequencing (especially power up) can be compatible between many panels
means that there's a constant desire to plug multiple different panels
into the same board. This could be for second sourcing purposes or to
support multiple SKUs (maybe a 11" and a 13", for instance).
As discussed [1], it should be OK to support this by adding two
properties to the device tree to specify the delays needed for
powering up the panel the first time. We'll create a new "edp-panel"
bindings file and define the two delays that might need to be
specified. NOTE: in the vast majority of the cases (HPD is hooked up
and isn't glitchy or is debounced) even these delays aren't needed.

Currently it66121_probe returns -EPROBE_DEFER if the there is no remote
endpoint found in the device tree which doesn't seem helpful, since this
is not going to change later and it is never checked if the next bridge
has been initialized yet. It will fail in that case later while doing
drm_bridge_attach for the next bridge in it66121_bridge_attach.
Since the bindings documentation for it66121 bridge driver states
there has to be a remote endpoint defined, its safe to return -EINVAL
in that case.
This additonally adds a check, if the remote endpoint is enabled and
returns -EPROBE_DEFER, if the remote bridge hasn't been initialized
(yet).

In a cl submission, when bin job initialization fails, sched job resources
were already allocated for the render job. At this point,
drm_sched_job_init(render) was done in v3d_job_init but the render job is
aborted before drm_sched_job_arm (in v3d_job_push) happens; therefore, not
only v3d_job_put but also drm_sched_job_cleanup should be called (by
v3d_job_cleanup). A similar issue is addressed for csd and tfu submissions.
The issue was noticed from a review by Iago Toral in a patch that touches
the same part of the code.

It turns out that when locking a region, the region must be a naturally
aligned power of 2. The upshot of this is that if the desired region
crosses a 'large boundary' the region size must be increased
significantly to ensure that the locked region completely covers the
desired region. Previous calculations (including in kbase for the
proprietary driver) failed to take this into account.
Since it's known that the lock region must be naturally aligned we can
compute the required size by looking at the highest bit position which
changes between the start/end of the lock region (subtracting 1 from the
end because the end address is exclusive). The start address is then
aligned based on the size (this is technically unnecessary as the
hardware will ignore these bits, but the spec advises to do this "to
avoid confusion").

not the least because to update the device ID the BIOS has to be

Display drivers so far need to have a lot of boilerplate to first
retrieve either the panel or bridge that they are connected to using
drm_of_find_panel_or_bridge(), and then either deal with each with ad-hoc
functions or create a drm panel bridge through drm_panel_bridge_add.
In order to reduce the boilerplate and hopefully create a path of least
resistance towards using the DRM panel bridge layer, let's create the
function devm_drm_of_get_bridge() to reduce that boilerplate.

"Updates for the SMP and CPU hotplug:
- Remove DEFINE_SMP_CALL_CACHE_FUNCTION() which is a left over of the

It's not longer required as the hotplug callbacks are guaranteed to
be invoked on the upcoming CPU.

Pull misc driver fix from Greg KH:
"Here is a single patch for 5.15-rc1, for the lkdtm misc driver.
It resolves a build issue that many people were hitting with your
current tree, and Kees and others felt would be good to get merged
before -rc1 comes out, to prevent them from having to constantly hit
it as many development trees restart on -rc1, not older -rc releases.
It has NOT been in linux-next, but has passed 0-day testing and looks
'obviously correct' when reviewing it locally :)"

Pull smbfs updates from Steve French:

- DFS reconnect fix
- begin creating common headers for server and client

more accurate, as the very old cifs dialect has long been
superseded by smb3 dialects).
In the future we can rename the fs/cifs directory to fs/smbfs.
