The default hpd_wait_us in panel_edp.c is 2 seconds. This makes the
sleep time in the polling of _ps8640_wait_hpd_asserted become 200ms.
Change it to a constant 20ms to speed up the function.

Do not generate the HS front and back porch gaps, the HSA gap and
EOT packet, as per "SN65DSI83 datasheet SLLSEC1I - SEPTEMBER 2012
- REVISED OCTOBER 2020", page 22, these packets are not required.
This makes the TI SN65DSI83 bridge work with Samsung DSIM on i.MX8MN.

The LDB driver currently checks whether dual mode is used, otherwise it
assumes only channel 0 is in use. Add support for using only channel 1. In
device tree terms, this means linking port 2 only.
Doing this cleanly requires changing the logic of the probe functions from
this:
1. use of_graph_get_remote_node() on port 1 to find the panel
2. use drm_of_lvds_get_dual_link_pixel_order() to detect dual mode
to this:
1. use of_graph_get_remote_node() twice to find remote ports
2. reuse the result of the above to know whether each channel is enabled
and to find the panel
3. if (both channels as enabled)
use drm_of_lvds_get_dual_link_pixel_order() to detect dual mode
Also add a dev_dbg() to log the detected mode and log an error in case no
panel was found (no channel enabled).

VPU on MTL has hardware optimizations and does not require 10ms
D0 - D3hot transition delay imposed by PCI specification (PCIe
r6.0, sec 5.9.) .
The delay removal is traditionally done by adding PCI ID to
quirk_remove_d3hot_delay() in drivers/pci/quirks.c . But since
we do not need that optimization before driver probe and we
can better specify in the ivpu driver on what (future) hardware
use the optimization, we do not use quirk_remove_d3hot_delay()
for that.

The TC358767/TC358867/TC9595 are capable of DSI burst mode, which
is more energy efficient than the non-burst modes. Make use of it.
The TC358767/TC358867/TC9595 are capable of DSI non-continuous clock,
since it sources the internal PLL clock from external clock source.
The DSI non-continuous clock further reduces power utilization.
The TC358767/TC358867/TC9595 may use DSI LPM for command transmissions,
make sure this is configured correctly in the DSI mode flags.

Some SoCs implementing ARM Mali GPUs are subject to speed binning:
this means that some versions of the same SoC model may need to be
limited to a slower frequency compared to the other:
this is being addressed by reading nvmem (usually, an eFuse array)
containing a number that identifies the speed binning of the chip,
which is usually related to silicon quality.
To address such situation, add basic support for reading the
speed-bin through nvmem, as to make it possible to specify the
supported hardware in the OPP table for GPUs.
This commit also keeps compatibility with any platform that does
not specify (and does not even support) speed-binning.

It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties.
Convert reading boolean properties to of_property_read_bool().

The nt36672a bindings were added with a mistake on VDDIO supply calling
it in one place vddio and in other vddi0. Typical name is rather vddio
which is also now used by DTS (sdm845-xiaomi-beryllium-common.dtsi) and
Linux driver.

As the finished fence is the one that is exposed to userspace, and
therefore the one that other operations, like atomic update, would
block on, we need to propagate the deadline from from the finished
fence to the actual hw fence.
v2: Split into drm_sched_fence_set_parent() (ckoenig)
v3: Ensure a thread calling drm_sched_fence_set_deadline_finished() sees
fence->parent set before drm_sched_fence_set_parent() does this
test_bit(DMA_FENCE_FLAG_HAS_DEADLINE_BIT).

It is preferred to use typed property access functions (i.e.

of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

Add extras to support i.MX8M Plus. The main change is the removal of
HS/VS/DE signal inversion in the LCDIFv3-DSIM glue logic, otherwise

with the i.MX8M Mini/Nano one.

Samsung MIPI DSIM controller is common DSI IP that can be used in various
SoCs like Exynos, i.MX8M Mini/Nano.
In order to access this DSI controller between various platform SoCs,
the ideal way to incorporate this in the drm stack is via the drm bridge
driver.
We already have a consolidated code for supporting component and bridge
based DRM drivers, so keep the exynos component based code in existing
exynos_drm_dsi.c and move generic bridge code as part of samsung-dsim.c
