3a936bc286 drm/meson: Fix an Alpha Primary Plane bug on Meson GXL/GXM SoCs
On the Amlogic GXL & GXM SoCs, a bug occurs on the primary plane when
alpha is used where the alpha is not aligned with the pixel content.

The workaround Amlogic implemented is to reset the OSD1 plane hardware
block each time the plane is (re)enabled, solving the issue.

In the reset, we still need to save the content of 2 registers which
depends on the status of the plane, in addition to reload the scaler
conversion matrix at the same time.

ff217bc710 drm/meson: Add support for VIC alternate timings
This change is an attempt to handle the alternate clock for the CEA mode.
60Hz vs. 59.94Hz, 30Hz vs 29.97Hz or 24Hz vs 23.97Hz on the Amlogic Meson SoC
DRM Driver pixel clock generation.

The actual clock generation will be moved to the Common Clock framework once
all the video clock are handled by the Amlogic Meson SoC clock driver,
then these alternate timings will be handled in the same time in a cleaner
fashion.

[  118.292699] Disabling lock debugging due to kernel taint

It seems that when looping through the OSD EOTF LUT maps, we use the
same max iterator for OETF: 20. This is wrong though, since 20*2 is 40,
which means that we'll stop out of bounds on the EOTF maps.

But, this whole thing is already confusing enough to read through as-is,
so let's just replace all of the hardcoded sizes with
OSD_(OETF/EOTF)_LUT_SIZE / 2.

2bcd3ecab7 drm/meson: Fixes for drm_crtc_vblank_on/off support
Since Linux 4.17, calls to drm_crtc_vblank_on/off are mandatory, and we get
a warning when ctrc is disabled :
" driver forgot to call drm_crtc_vblank_off()"

But, the vsync IRQ was not totally disabled due the transient hardware
state and specific interrupt line, thus adding proper IRQ masking from
the HHI system control registers.

The last change fixes a race condition introduced by calling the added
drm_crtc_vblank_on/off when an HPD event occurs from the HDMI connector,
triggering a WARN_ON() in the _atomic_begin() callback when the CRTC
is disabled, thus also triggering a WARN_ON() in drm_vblank_put() :

WARNING: CPU: 0 PID: 1185 at drivers/gpu/drm/meson/meson_crtc.c:157 meson_crtc_atomic_begin+0x78/0x80

  drm_atomic_helper_wait_for_vblanks.part.9+0x130/0x2b8
  drm_atomic_helper_commit_tail+0x68/0x80
[...]

The issue is that vblank need to be enabled in any occurrence of :
- atomic_enable()
- atomic_begin() and state->enable == true, which was not the case

Moving the CRTC enable code to a common function and calling in one of
these occurrence solves this race condition and makes sure vblank is
enabled in each call to _atomic_begin() from the HPD event leading to
drm_atomic_helper_commit_planes().

To Summarize :
- Make sure that the CRTC code will call the drm_crtc_vblank_on()/off()
- *Really* mask the Vsync IRQ
- Initialize and enable vblank at the first
  atomic_begin()/_atomic_enable()

7db647aa8b drm/meson: Add primary plane scaling
This patch adds support for the Primary Plane scaling.

On the Amlogic GX SoCs, the primary plane is used as On-Screen-Display
layer on top of video, and it's needed to keep the OSD layer to a lower
size as the physical display size to :
- lower the memory bandwidth
- lower the OSD rendering
- lower the memory usage

This use-case is used when setting the display mode to 3840x2160 and the
OSD layer is rendered using the GPU. In this case, the GXBB & GXL cannot
work on more than 2000x2000 buffer, thus needing the OSD layer to be kept
at 1920x1080 and upscaled to 3840x2160 in hardware.

The primary plane atomic check still allow 1:1 scaling, allowing native
3840x2160 if needed by user-space applications.

f9a2348196 drm/meson: Support Overlay plane for video rendering
The Amlogic Meson GX SoCs support an Overlay plane behind the primary
plane for video rendering.

This Overlay plane support various YUV layouts :
- YUYV
- NV12 / NV21
- YUV444 / 422 / 420 / 411 / 410

The scaler supports a wide range of scaling ratios, but for simplicity,
plane atomic check limits the scaling from x5 to /5 in vertical and
horizontal scaling.

The z-order is fixed and always behind the primary plane and cannot be changed.

The scaling parameter algorithm was taken from the Amlogic vendor kernel
code and rewritten to match the atomic universal plane requirements.

The video rendering using this overlay plane support has been tested using
the new Kodi DRM-KMS Prime rendering path along the in-review V4L2 Mem2Mem
Hardware Video Decoder up to 3840x2160 NV12 frames on various display modes.

efbb9df91e drm/meson: Use drm_fbdev_generic_setup()
The CMA helper is already using the drm_fb_helper_generic_probe part of
the generic fbdev emulation. This patch makes full use of the generic
fbdev emulation by using its drm_client callbacks. This means that
drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are
now handled by the emulation code. Additionally fbdev unregister happens
automatically on drm_dev_unregister().

The drm_fbdev_generic_setup() call is put after drm_dev_register() in the
driver. This is done to highlight the fact that fbdev emulation is an
internal client that makes use of the driver, it is not part of the
driver as such. If fbdev setup fails, an error is printed, but the driver
succeeds probing.

3273fc63e1 drm/meson: Make DMT timings parameters and pixel clock generic
Remove the modes timings tables for DMT modes and calculate the HW
paremeters from the modes timings.

Switch the DMT modes pixel clock calculation out of the static frequency
list to a generic calculation from a range of possible PLL dividers.

This patch is an intermediate step towards usage of the Common Clock
Framwework for PLL setup, by reworking the code to have common
sel_pll() function called by the CEA (HDMI) freq setup and the generic
DMT frequencies setup, we should be able to simply call clk_set_rate()
on the PLL clock handle in a near future.

The CEA (HDMI) and CVBS modes needs very specific clock paths that CCF will
never be able to determine by itself, so there is still some work to do for
a full handoff to CCF handling the clocks.

This setup permits setting non-CEA modes like :
- 1600x900-60Hz
- 1280x1024-75Hz
- 1280x1024-60Hz
- 1440x900-60Hz
- 1366x768-60Hz
- 1280x800-60Hz
- 1152x864-75Hz
- 1024x768-75Hz
- 1024x768-70Hz
- 1024x768-60Hz
- 832x624-75Hz
- 800x600-75Hz
- 800x600-72Hz

e88230a374 drm/meson: fix vsync buffer update
The plane buffer address/stride/height was incorrectly updated in the
plane_atomic_update operation instead of the vsync irq.
This patch delays this operation in the vsync irq along with the
other plane delayed setup.

This issue was masked using legacy framebuffer and X11 modesetting, but
is clearly visible using gbm rendering when buffer is submitted late after
vblank, like using software decoding and OpenGL rendering in Kodi.
With this patch, tearing and other artifacts disappears completely.

dw_hdmi shouldn't set drvdata since some drivers might need to store
it's own data there. Rework dw_hdmi in a way to return struct dw_hdmi
instead to store it in drvdata. This way drivers are responsible to
store and pass structure when needed.

Idea was taken from the following commit:
8242ecbd59 ("drm/bridge/synopsys: stop clobbering drvdata")

drm/bridge/synopsys: dw-hdmi: Export some PHY related functions
Parts of PHY code could be useful also for custom PHYs. For example,
Allwinner A83T has custom PHY which is probably Synopsys gen2 PHY
with few additional memory mapped registers, so most of the Synopsys PHY
related code could be reused.

Functions exported here are actually not specific to Synopsys PHYs but
to DWC HDMI controller PHY interface. This means that even if the PHY is
completely custom, i.e. not designed by Synopsys, exported functions can
be useful.

13eff9ae52 drm/meson: Use drm_mode_get_hv_timing() to populate plane clip rectangle
Use drm_mode_get_hv_timing() to fill out the plane clip rectangle.

No functional changes as the code already uses crtc_state->mode
to populate the clip, which is also what drm_mode_get_hv_timing()
uses.

Once everyone agrees on this we can move the clip handling into
drm_atomic_helper_check_plane_state().

10b47ee02d drm: Check crtc_state->enable rather than crtc->enabled in drm_plane_helper_check_state()
drm_plane_helper_check_state() is supposed to do things the atomic way,
so it should not be inspecting crtc->enabled. Rather we should be
looking at crtc_state->enable.

We have a slight complication due to drm_plane_helper_check_update()
reusing drm_plane_helper_check_state() for non-atomic drivers. Thus
we'll have to pass the crtc_state in manally and construct a fake
crtc_state in drm_plane_helper_check_update().

e6fc3b6855 drm: Plumb modifiers through plane init
This is the plumbing for supporting fb modifiers on planes. Modifiers
have already been introduced to some extent, but this series will extend
this to allow querying modifiers per plane. Based on this, the client to
enable optimal modifications for framebuffers.

This patch simply allows the DRM drivers to initialize their list of
supported modifiers upon initializing the plane.

v2: A minor addition from Daniel

v3:
* Updated commit message
* s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu)
* Remove some excess newlines (Liviu)
* Update comment for > 64 modifiers (Liviu)

v4: Minor comment adjustments (Liviu)

v5: Some new platforms added due to rebase

v6: Add some missed plane inits (or maybe they're new - who knows at
this point) (Daniel)

8604889f83 drm/meson: Fix driver bind when only CVBS is available
While introducing HDMI support, component matching on connectors node
were bypassed since no driver would actually bind on the DT node.
But when only a CVBS connector is present, only a single node is found
in the graph, but ignored and a NULL match table is given to the
component code.

This code permits bypassing the components framework by binding directly
the DRM driver when no components needs to be loaded.
