drm/sun4i: sun6i_mipi_dsi: Support DSI GENERIC_SHORT_WRITE_2 transfer
Some DSI panels do use GENERIC_SHORT_WRITE_2 transfer protocol to host
DSI driver and which is similar to GENERIC_SHORT_WRITE.

Add support for the same transfer, so-that so-that the panels which are
requesting similar transfer type will process properly.

drm/sun4i: sun6i_mipi_dsi: Fix hsync_porch overflow
Loop N1 instruction delay for burst mode devices are computed
based on horizontal sync and porch timing values.

The current driver is using u16 type for computing this hsync_porch
value, which would failed to fit within the u16 type for large sync
and porch timings devices. This would result in hsync_porch overflow
and eventually computed wrong instruction delay value.

Example, timings, where it produces the overflow
{
	.hdisplay       = 1080,
	.hsync_start    = 1080 + 408,
        .hsync_end      = 1080 + 408 + 4,
        .htotal         = 1080 + 408 + 4 + 38,
}

It reproduces the desired delay value 65487 but the correct working
value should be 7.

So, Fix it by computing hsync_porch value separately with u32 type.

drm/sun4i: Fix sun8i HDMI PHY clock initialization
Current code initializes HDMI PHY clock driver before reset line is
deasserted and clocks enabled. Because of that, initial readout of
clock divider is incorrect (0 instead of 2). This causes any clock
rate with divider 1 (register value 0) to be set incorrectly.

Fix this by moving initialization of HDMI PHY clock driver after reset

Pull drm updates from Dave Airlie:
 "This has two exciting community drivers for ARM Mali accelerators.
  Since ARM has never been open source friendly on the GPU side of the
  house, the community has had to create open source drivers for the
  Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
  series. Well done to all involved and hopefully this will help ARM
  head in the right direction.

  There is also now the ability if you don't have any of the legacy
  drivers enabled (pre-KMS) to remove all the pre-KMS support code from
  the core drm, this saves 10% or so in codesize on my machine.

  i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
  moves out of staging.

  There are also some rcar-du patches which crossover with media tree
  but all should be acked by Mauro.

Paul Kocialkowski e02bc29b2c drm/sun4i: Unbind components before releasing DRM and memory
Our components may still be using the DRM device driver (if only to
access our driver's private data), so make sure to unbind them before
the final drm_dev_put.

Also release our reserved memory after component unbind instead of
before to match reverse creation order.

drm/sun4i: Use DRM_GEM_CMA_VMAP_DRIVER_OPS for GEM operations
Our driver makes a typical use of CMA, with GEM object allocated as
GEM CMA objects. Use DRM_GEM_CMA_VMAP_DRIVER_OPS to describe the ops
instead of duplicating them.

Because DRM_GEM_CMA_VMAP_DRIVER_OPS implements a gem_create_object op
which sets per-object funcs (drm_cma_gem_default_funcs), we can also
get rid of free_object_unlocked and gem_vm_ops, which are superseded
by the object funcs.

drm/sun4i: Rely on dma interconnect for our RAM offset
Now that we can express our DMA topology, rely on those property instead of
hardcoding an offset from the dma_addr_t which wasn't really great.

We still need to add some code to deal with the old DT that would lack that
property, but we move the offset to the DRM device dma_pfn_offset to be
able to rely on just the dma_addr_t associated to the GEM object.

drm/sun4i: tcon top: Fix NULL/invalid pointer dereference in sun8i_tcon_top_un/bind
There are two problems here:

1. Not all clk_data->hws[] need to be initialized, depending on various
   configured quirks. This leads to NULL ptr deref in
   clk_hw_unregister_gate() in sun8i_tcon_top_unbind()
2. If there is error when registering the clk_data->hws[],
   err_unregister_gates error path will try to unregister
   IS_ERR()=true (invalid) pointer.

For problem (1) I have this stack trace:

Maxime Ripard e2771deb5d
drm/sun4i: rgb: Change the pixel clock validation check
The current code, since commit bb43d40d7c ("drm/sun4i: rgb: Validate the
clock rate"), perform some validation on the pixel clock to filter out the
EDID modes provided by monitors (through bridges) that we wouldn't be able
to reach. For the usual modes, we're able to generate a perfect clock rate,
so a strict check was enough.

However, this had the side effect of preventing displays that would work
otherwise to operate properly, since we would pretty much never be able to
generate an exact rate for those displays, even though we would fall within
that panel tolerance.

This was also shown to happen for unusual modes exposed through EDIDs, for
example on eDP panels.

We can work around this by simplifying a bit the problem: no panels we've
encountered so far actually needed that check. All of them are tied to a
particular board when it is produced, and made to work with the Allwinner
BSP. That pretty much guarantees that we never have a pixel clock out of
reach.

On the other hand, the EDIDs modes that needed to be validated have always
been exposed through bridges.

Let's just use that metric to instead of validating all modes, only
validate modes when we have a bridge attached. It should be good enough for
now, while we still have room for improvements or refinements using the
display_timings structure for example for panels.

We also add a tolerance for EDID-based modes instead of doing a strict
check. This tolerance is of 0.5% which is the one advertised in the VESA
DVT and CVT specs. If that needed to be extended in the future, we can add
a custom module parameter to relax it a bit.

drm/sun4i: Improve VI scaling for DE2/DE3
VI planes support coarse scaling which helps to overcome VI scaler
limitations. While exact working of coarse scaling isn't known, it seems
that it just skips programmed amount of rows and columns. This is
especially useful for downscaling very big planes (4K down to 1080p).

Horizontal coarse scaling is currently used to fit one line to VI scaler
buffer.

Vertical coarse scaling is used to assure that VI scaler is actually
capable of processing framebuffer in one frame time.

drm/sun4i: dsi: Change the start delay calculation
The current calculation for the video start delay in the current DSI driver
is that it is the total vertical size, minus the front porch and sync length,
plus 1. This equals to the active vertical size plus the back porch plus 1.

That 1 is coming in the Allwinner BSP from an variable that is set to 1.
However, if we look at the Allwinner BSP more closely, and especially in
the "legacy" code for the display (in drivers/video/sunxi/legacy/), we can
see that this variable is actually computed from the porches and the sync
minus 10, clamped between 8 and 100.

This fixes the start delay symptom we've seen on some panels (vblank
timeouts with vertical white stripes at the bottom of the panel).

drm/sun4i: dsi: Restrict DSI tcon clock divider
The current code allows the TCON clock divider to have a range between 4
and 127 when feeding the DSI controller.

The only display supported so far had a display clock rate that ended up
using a divider of 4, but testing with other displays show that only 4
seems to be functional.

This also aligns with what Allwinner is doing in their BSP, so let's just
hardcode that we want a divider of 4 when using the DSI output.

drm/sun4i: dsi: Fix unitialized variable warning
Since the DPHY rework, one error path doesn't set the return error code
before jumping to its error label, which in turns make gcc (rightfully)
complain about the variable holding the error code being uninitialized.

Fix this.

generic way with MIPI D-PHY phys, let's convert our PHY driver and its
associated DSI driver to that new API.

drm/sun4i: tcon: Prepare and enable TCON channel 0 clock at init
When initializing clocks, a reference to the TCON channel 0 clock is
obtained. However, the clock is never prepared and enabled later.
Switching from simplefb to DRM actually disables the clock (that was
usually configured by U-Boot) because of that.

On the V3s, this results in a hang when writing to some mixer registers
when switching over to DRM from simplefb.

Fix this by preparing and enabling the clock when initializing other
clocks. Waiting for sun4i_tcon_channel_enable to enable the clock is
apparently too late and results in the same mixer register access hang.
