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.

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.

drm_mode_parse_cmdline_options()
Add a freestanding function argument to drm_mode_parse_cmdline_options()
similar to how drm_mode_parse_cmdline_extra() already has this.
This is a preparation patch for allowing parsing of stand-alone options
without a mode before them, e.g.: video=HDMI-1:margin_right=14,...

Refactor drm_mode_parse_cmdline_options() so that it takes a pointer
to the first option, rather then a pointer to the ',' before the first
option.

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.

Before this commit it was impossible to add an extra mode argument after
a bpp or refresh specifier, combined with an option, e.g.
video=HDMI-1:720x480-24e,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 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).

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.

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.

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.

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.

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.

Udl has a single display pipeline with a primary plane; perfect for
simple-pipe helpers. Convert it over. The old encoder and CRTC code
becomes unused and obsolete.
Exported formats for the primary plane are RGB565 and XRGB8888, with
the latter being emulated. The 16-bit format is the default and what
is used when communicating with the device.
This patch enables atomic modesetting for udl devices.
v3:
* remove unused field crtc from struct udl_device
* set crtc_state->no_vblank at beginning of enable()
v2:
* move suspend/resume changes into separate patch
* remove non-atomic code

NOTE: This patch only adds the default CMA heap. We will enable
selectively adding other CMA memory regions to the dmabuf heaps
interface with a later patch (which requires a dt binding)

This framework allows a unified userspace interface for dma-buf
exporters, allowing userland to allocate specific types of memory
for use in dma-buf sharing.
Each heap is given its own device node, which a user can allocate
a dma-buf fd from using the DMA_HEAP_IOC_ALLOC.
This code is an evoluiton of the Android ION implementation,
and a big thanks is due to its authors/maintainers over time
for their effort:
Rebecca Schultz Zavin, Colin Cross, Benjamin Gaignard,
Laura Abbott, and many other contributors!
