Sending this out again, to get it based on drm-misc-next.

This patchset contains one fix (in the front, so its easier to
eventually backport), and a series of changes from YiPing to
refactor the kirin drm driver so that it can be used on both
kirin620 based devices (like the original HiKey board) as well
as kirin960 based devices (like the HiKey960 board).

The full kirin960 drm support is still being refactored, but as
this base kirin rework was getting to be substantial, I wanted
to send out the first chunk, so that the review burden wasn't
overwhelming.

The full HiKey960 patch stack can be found here:
  https://git.linaro.org/people/john.stultz/android-dev.git/log/?h=dev/hikey960-mainline-WIP

thanks
-john


New in v4:
* Rebased to drm-misc-next, minor tweaks to merge changes
* Dropped "drm: kirin: Get rid of drmP.h includes" as similar change
  was already in drm-misc next
* Added acked-by tag from Xinliang

From: Da Lv <lvda3@hisilicon.com>

The original HiKey (620) board has had a long running issue
where when using a 1080p montior, the display would occasionally
blink and come come back with a horizontal offset (usually also
shifting the colors, depending on the value of the offset%4).

After lots of analysis by HiSi developers, they found the issue
was due to when running at 1080p, it was possible to hit the
device memory bandwidth limits, which could cause the DSI signal
to get out of sync.

Unfortunately the DSI logic doesn't have the ability to
automatically recover from this situation, but we can get a an
LDI underflow interrupt when it happens.

To then correct the issue, when we get an LDI underflow irq, we
we can simply suspend and resume the display, which resets the
hardware.

Thus, this patch enables the ldi underflow interrupt, and
initializes a workqueue that is used to suspend/resume the
display to recover. Then when the irq occurs we clear it and
schedule the workqueue to reset display engine.

The CONFIG_HISI_KIRIN_DW_DSI option is only used w/ kirin
driver, so cut out the middleman and condense the config
logic down.

From: Xu YiPing <xuyiping@hisilicon.com>

In a few functions, we pass in a struct ade_crtc, which we only
use to get to the underlying struct ade_hw_ctx.

Thus this patch refactors the functions to just take the
struct ade_hw_ctx directly.

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch removes the out_format
field in the struct ade_crtc, which was only ever set to
LDI_OUT_RGB_888.

Thus this patch removes the field and instead directly uses
LDI_OUT_RGB_888.

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch modifies the
initialization function to dynamically allocate the ade_hw_ctx
structure previously kept as part of struct ade_data.

This is done so that later we can have the hw_ctx point to
hardware revision specific ctx structures.

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch modifies the
initialization routines so the devm_request_irq() function
is called as part of the allocation function.

This will be needed in the future when we will have different
allocation functions to allocate hardware specific hw_ctx
structures, which will setup the vblank irq differently.

The workqueue used to reset the display when we hit an LDI
underflow error is ADE specific, so since this patch series
works to make the kirin_crtc structure more generic, move the
workqueue to the ade_hw_ctx structure instead.

As part of refactoring the kirin driver to better support
different hardware revisions, this patch moves some shared
structures and helpers to the common kirin_drm_drv.h

These structures will later used by both kirin620 and
future kirin960 driver

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch moves some shared
structures and helpers to the common kirin_drm_drv.h

These structures will later used by both kirin620 and
future kirin960 driver

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch moves the mode config
initialization values into the kirin_drm_data structure.

This will make it easier to add support for new devices
via a new kirin_drm_data structure.

As part of refactoring the kirin driver to better support
different hardware revisions, this patch moves the max_width
and max_height values used in kirin_drm_mode_config_inita to
hardware specific driver data.

This will make it easier to add support for new devices
via a new kirin_drm_data structure.

As part of refactoring the kirin driver to better support
different hardware revisions, this patch moves the drm_driver
structure to be under device specific driver data.

This will allow us to more easily add support for kirin960
hardware with later patches.

As part of refactoring the kirin driver to better support
different hardware revisions, this patch adds a flag to the
device specific driver data so that we can conditionally
register the connectors at init.

As part of refactoring the kirin driver to better support
different hardware revisions, this patch renames
ade_crtc/plane_init kirin_plane/crtc_init, as they will later be
moved to kirin drm drv and shared with the kirin960 hardware
support.

As part of refactoring the kirin driver to better support
different hardware revisions, this patch changes the
dev->driver_data to point to a drm_device, not ade_data.

Thus we set the driver data to drm device after alloc.

As part of refactoring the kirin driver to better support
different hardware revisions, this patch changes the driver_data
value to not be a global variable. Instead the driver_data value
is accessed via the of_device_get_match_data() when needed.

This will allow the ade_drm_init to later be made generic and

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch changes the code
via a passed in driver_data pointer, rather than hardcoding
them via ade_driver_data variable.

This will allow those funcitons to be later moved to the
generic kirin_drm_drv.c using alternative driver_data structures
that support other hardware.

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch renames ade_data to
kirin_drm_private, and moves crtc_init and plane_init to
kirin drm drv too. Now that they are generic the functions
can be shared between the kirin620 and (to be added later)
kirin960 specific support code.

There was some checkpatch noises in some of the patches - please verify
with "--strict".
Mostly alignment of parameters with open parantesis
Sample - but there was similar issues in other patches:

It was a simple allmodconfig build where I did:

Please fix and resend. I did not look further.

It was a simple allmodconfig build where I did:

make drivers/gpu/drm/hisilicon/

Please fix and resend. I did not look further.

Yes, I've not used modules much with the board. I'll fix this up.

Apologies again, thanks so much for finding these issues! I'll get a
new series to you shortly once the issues are resolved and I've
