d1fe276b51 drm/modes: parse_cmdline: Explicitly memset the passed in drm_cmdline_mode struct
Instead of only setting mode->specified on false on an early exit and
leaving e.g. mode->bpp_specified and mode->refresh_specified as is,
lets be consistent and just zero out the entire passed in struct at
the top of drm_mode_parse_command_line_for_connector()

Changes in v3:
-Drop "mode->specified = false;" line instead of the "return false;" (oops)

5b926617cd drm/modes: parse_cmdline: Remove some unnecessary code (v2)
fb_get_options() will return fb_mode_option if no video=<connector-name>
argument is present on the kernel commandline, so there is no need to also
do this in drm_mode_parse_command_line_for_connector() as our only caller
uses fb_get_options() to get the mode_option argument.

Changes in v2:
-Split out the changes dealing with the initialization of the mode struct
 into a separate patch

4e7a4a6fbd drm/modes: parse_cmdline: Add support for specifying panel_orientation (v2)
Sometimes we want to override a connector's panel_orientation from the
kernel commandline. Either for testing and for special cases, e.g. a kiosk
like setup which uses a TV mounted in portrait mode.

Users can already specify a "rotate" option through a video= kernel cmdline
option. But that only supports 0/180 degrees (see drm_client_modeset TODO)
and only works for in kernel modeset clients, not for userspace kms users.

The "panel-orientation" connector property OTOH does support 90/270 degrees
as it leaves dealing with the rotation up to userspace and this does work
for userspace kms clients (at least those which support this property).

Changes in v2:
-Add missing ':' after @panel_orientation (reported by kbuild test robot)

7b1cce760a drm/modes: parse_cmdline: Allow specifying stand-alone options
Some options which can be specified on the commandline, such as
margin_right=..., margin_left=..., etc. are applied not only to the
specified mode, but to all modes. As such it would be nice if the user
can simply say e.g.
video=HDMI-1:margin_right=14,margin_left=24,margin_bottom=36,margin_top=42

This commit refactors drm_mode_parse_command_line_for_connector() to
add support for this, and as a nice side effect also cleans up the
function a bit.

6a2d163756 drm/modes: parse_cmdline: Set bpp/refresh_specified after successful parsing
drm_connector_get_cmdline_mode() calls
drm_mode_parse_command_line_for_connector() with &connector->cmdline_mode
as mode argument, so anything which we store in the mode arguments gets
kept even if we return false.

Avoid storing a possibly false-postive bpp/refresh_specified setting
in connector->cmdline_mode by moving the setting of these to after
successful parsing of the bpp/refresh parts of the video= argument.

cfb0881b8f drm/modes: parse_cmdline: Accept extras directly after mode combined with options
Before this commit it was impossible to combine an extra mode argument
specified directly after the resolution with an option, e.g.
video=HDMI-1:720x480e,rotate=180 would not work, either the "e" to force
enable would need to be dropped or the ",rotate=180", otherwise the
mode_option would not be accepted.

This commit fixes this by setting parse_extras to true in this case, so
that drm_mode_parse_cmdline_res_mode() parses the extra arguments directly
after the resolution.

c2ed3e9419 drm/modes: parse_cmdline: Stop parsing extras after bpp / refresh at ', '
Before this commit it was impossible to add an extra mode argument after
a bpp or refresh specifier, combined with an option, e.g.

This commit fixes this by fixing the length calculation if extras_ptr
is set to stop the extra parsing at the start of the options (stop at the
',' options_ptr points to).

8582e244e5 drm/modes: parse_cmdline: Fix possible reference past end of string
Before this commit, if the last option of a video=... option is for
example "rotate" without a "=<value>" after it then delim will point to
the terminating 0 of the string, and value which is sets to <delim + 1>
will point one position past the end of the string.

This commit fixes this by enforcing that the contents of delim equals '='
as it should be for options which take a value, this check is done in a
new drm_mode_parse_cmdline_int helper function which factors out the
common integer parsing code for all the options which take an int.

94bedc45ac drm/rockchip: add ability to handle external dphys in mipi-dsi
While the common case is that the dsi controller uses an internal dphy,
accessed through the phy registers inside the dsi controller, there is
also the possibility to use a separate dphy from a different vendor.

One such case is the Rockchip px30 that uses a Innosilicon Mipi dphy,
so add the support for handling such a constellation, including the pll
also getting generated inside that external phy.

89bddff6be drm/bridge/synopsys: dsi: move phy_ops callbacks around panel enablement
If implementation-specific phy_ops need to be defined they probably
should be enabled before trying to talk to the panel and disabled only
after the panel was disabled.

Right now they are enabled last and disabled first, so might make it
impossible to talk to some panels - example for this being the px30
with an external Innosilicon dphy that needs the phy to be enabled
to transfer commands to the panel.

So move the calls appropriately.

25ed8aeb9c drm/bridge/synopsys: dsi: driver-specific configuration of phy timings
The timing values for dw-dsi are often dependent on the used display and
according to Philippe Cornu will most likely also depend on the used phy
technology in the soc-specific implementation.

To solve this and allow specific implementations to define them as needed
add a new get_timing callback to phy_ops and call this from the dphy_timing
function to retrieve the necessary values for the specific mode.

Right now this handles the hs2lp + lp2hs where Rockchip SoCs need handling
according to the phy speed, while STM seems to be ok with static values.

changes in v5:
- rebase on 5.5-rc1
- merge into px30 dsi series to prevent ordering conflicts

changes in v4:
- rebase to make it directly fit on top of drm-misc-next after all

changes in v3:
- check existence of phy_ops->get_timing in __dw_mipi_dsi_probe()
- emit actual error when get_timing() call fails
- add tags from Philippe and Yannick

changes in v2:
- add driver-specific handling, don't force all bridge users to use
  the same timings, as suggested by Philippe

2e6d304515 Merge branch 'remove-ksys-mount-dup' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux
Pull ksys_mount() and ksys_dup() removal from Dominik Brodowski:
 "This small series replaces all in-kernel calls to the
  userspace-focused ksys_mount() and ksys_dup() with calls to
  kernel-centric functions:

  For each replacement of ksys_mount() with do_mount(), one needs to
  verify that the first and third parameter (char *dev_name, char *type)
  are strings allocated in kernelspace and that the fifth parameter
  (void *data) is either NULL or refers to a full page (only occurence
  in init/do_mounts.c::do_mount_root()). The second and fourth
  parameters (char *dir_name, unsigned long flags) are passed by
  ksys_mount() to do_mount() unchanged, and therefore do not require
  particular care.

  Moreover, instead of pretending to be userspace, the opening of
  /dev/console as stdin/stdout/stderr can be implemented using in-kernel
  functions as well. Thereby, ksys_dup() can be removed for good"

[ This doesn't get rid of the special "kernel init runs with KERNEL_DS"
  case, but it at least removes _some_ of the users of "treat kernel
  pointers as user pointers for our magical init sequence".

  One day we'll hopefully be rid of it all, and can initialize our
  init_thread addr_limit to USER_DS.    - Linus ]

* 'remove-ksys-mount-dup' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux:
  fs: remove ksys_dup()
  init: unify opening /dev/console as stdin/stdout/stderr

7a90f89904 drm/i915/gem: Serialise object before changing cache-level
Wait for the object to be idle before changing its cache-level and
unbinding. This was dropped as supposedly superfluous from commit
8b1c78e06e ("drm/i915: Avoid calling i915_gem_object_unbind holding
object lock"), but it turns out to prevent some cache dirt escaping.
Smells like papering over a race...

1698174271 binder: fix incorrect calculation for num_valid
For BINDER_TYPE_PTR and BINDER_TYPE_FDA transactions, the
num_valid local was calculated incorrectly causing the
range check in binder_validate_ptr() to miss out-of-bounds
offsets.

cd6a1ca386 drm/gma500: Pass GPIO for Intel MID using descriptors
The GMA500 driver is using the legacy GPIO API to fetch
three optional display control GPIO lines from the SFI
description used by the Medfield platform.

Switch this over to use GPIO descriptors and delete the
custom platform data.

We create three new static locals in the tc35876x bridge
code but it is hardly any worse than the I2C client static
local already there: I tried first to move it to the DRM
driver state container but there are workarounds for
probe order in the code so I just stayed off it, as the
result is unpredictable.

People wanting to do a more throrugh and proper cleanup
of the GMA500 driver can work on top of this, I can't
solve much more since I don't have access to the hardware,
I can only attempt to tidy up my GPIO corner.
