[ Upstream commit 0ff9f49646353ce31312411e7e7bd2281492a40e ]
Currently the driver overwrites the surface depth provided by the fb
helper to give an invalid bpp/surface depth combination.
This has been exposed by commit 70109354fed2 ("drm: Reject unknown legacy
bpp and depth for drm_mode_addfb ioctl"), which now causes the driver to
fail to probe.
Fix by not overwriting the surface depth.

[ Upstream commit 331d880b35a76b5de0eec8cbcecbf615d758a5f9 ]
In hibmc_drm_fb_create(), when the call to hibmc_framebuffer_init() fails
with error, do not store the error code in the HiBMC device frame-buffer
pointer, as this will be later checked for non-zero value in
hibmc_fbdev_destroy() when our intention is to check for a valid function
pointer.
This fixes the following crash:

The driver doesn't support scaling, but when an atomic test is done
it repeatedly spits out this warning which isn't particularly useful.
So just remove the error message.

The method struct drm_connector_helper_funcs::mode_valid is defined
as returning an 'enum drm_mode_status' but the driver implementation
for this method uses an 'int' for it.
Fix this by using 'enum drm_mode_status' in the driver too.

This patch fixes the following soft lockup:
BUG: soft lockup - CPU#0 stuck for 23s! [weston:307]
On weston idle-timeout the IP is powered down and reset
asserted. On weston resume we get a massive vblank
IRQ storm due to the LDI registers having lost some state.
This state loss is caused by ade_crtc_atomic_begin() not
calling ade_ldi_set_mode(). With this patch applied
resuming from Weston idle-timeout works well.

Currently the hikey dsi logic cannot generate accurate byte
clocks values for all pixel clock values. Thus if a mode clock
is selected that cannot match the calculated byte clock, the
device will boot with a blank screen.
This patch uses the new mode_valid callback (many thanks to
Jose Abreu for upstreaming it!) to ensure we don't select
modes we cannot generate.
Also, since the ade crtc code will adjust the mode in mode_set,
this patch also adds a mode_fixup callback which we use to make
sure we are validating the mode clock that will eventually be
used.

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.
drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

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)

- FBINFO_CAN_FORCE_OUTPUT has been a lie ever since we nerfed&removed

restore kms panic output, but not through the bazillion of legacy
code layers called fbdev/fbcon, there's just no way to make that

- With the module check change FBINFO_DEFAULT is always 0, so can be

While at it, rename the operation to .atomic_enable() to be consistent

So this seems to be the first driver that does it the right way round,
so fix it up by calling drm_atomic_helper_shutdown instead. We need to
do that before the last kms user is gone (fbdev emulation), but before
we start shutting down hw stuff like interrupts.

Similar to the previous commit, convert drivers open coding OF graph
parsing to use drm_of_find_panel_or_bridge instead.
This changes some error messages to debug messages (in the graph core).
Graph connections are often "no connects" depending on the particular

Convert drivers to use the new of_graph_get_remote_node() helper
instead of parsing the endpoint node and then getting the remote device
node. Now drivers can just specify the device node and which
port/endpoint and get back the connected remote device node. The details
of the graph binding are nicely abstracted into the core OF graph code.

Less code ftw.
This converts all drivers except the tinydrm helper module. That one
needs more work, since it gets the THIS_MODULE reference from
tinydrm.ko instead of the actual driver module like it should.
Probably needs a similar trick like I used here with generating the
entire struct with a macro.

Instead of receiving the num_crts as a parameter, we can read it
directly from the mode_config structure. I audited the drivers that
invoke this helper and I believe all of them initialize the mode_config
struct accordingly, prior to calling the fb_helper.
I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates. The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.
