drm/tegra: Changes for v4.7-rc1

Two small changes, one getting rid of the bogus gamma table size and
another removing Terje from the MAINTAINERS file since he no longer does
any work on host1x or display.

* tag 'drm/tegra/for-4.7-rc1' of git://anongit.freedesktop.org/tegra/linux:
  MAINTAINERS: Remove Terje Bergström as Tegra DRM maintainer
  drm/tegra: Don't set a gamma table size

misc hisilicon cleanups.

* 'drm-hisilicon-next' of github.com:xin3liang/linux:
  drm/hisilicon: Fix DRM_INFO printed issue
  drm/hisilicon: Make kirin_drm_unbind sufficient
  drm/hisilicon: Use drm_connector_register_all

Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

 Summary:
   - expose HDMI-PHY clock to other drivers.
     . this patch was included in below patch series but I missed.
             http://www.spinics.net/lists/dri-devel/msg103097.html
   - some fixups about DECON5433 driver
     . this patch corrects vblank handling and fixes up trigger
       configuration.
   - use generic functions - gem_prime_mmap and dma_buf_mmap.
   - use DMA-Mapping API instead of specific one.
   - some code cleanups and fixeups.

* 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos:
  drm/exynos/decon5433: fix trigger configuration
  drm/exynos/dsi: use of_graph_get_endpoint_by_regs helper
  drm/exynos/dpi: use of_graph_get_endpoint_by_regs helper
  drm/exynos: Nuke dummy fb->dirty callback
  drm/exynos: use directly DMA mapping APIs on g2d
  drm/exynos/hdmi: Don't print error on deferral due to regulators
  drm/exynos: fix imported dma-buf to be mapped
  drm/exynos: support gem_prime_mmap
  drm/exynos: fimd: harden fimd_calc_clkdiv()
  drm/exynos: fix cancel page flip code
  drm/exynos/decon5433: do not use unnecessary software trigger
  drm/exynos/decon5433: handle vblank in vblank interrupt
  drm/exynos/hdmi: expose HDMI-PHY clock as pipeline clock

This patch fixed the bellow no DRM_INFO is printed issue:

if (!delay_count)
	DRM_INFO("phylock and phystopstateclklane is not ready.\n");

There will some printed issues with above info, under certain
circumstances:

If ((BIT(0) | BIT(2)) & val) is never true, break will not happen and
delay_count will be max u32 value (?), and no DRM_INFO is printed.

Also if ((BIT(0) | BIT(2)) & val) is true at the last possible
loop round, break happens, but now delay_count is already zero
( because of earlier delay_count-- ) and DRM_INFO is erroneously
printed.

Thanks to Juha Leppänen, he reports to me this issue.

It seems trigger cannot be configured too early, otherwise it does not work in
case of panel. The patch fixes also trigger flag logic, previously HW-TRIGGER
flag was cleared in case of panel - as a result panel used always software
trigger.

The regulators may not be available just because their driver's probe
function was just not executed and so the regulators not registered.

So, in this case the Exynos HDMI driver should not print logs since
a -EPROBE_DEFER is not really an error and that will just pollute
the kernel log and confuse users.

This patch prevents the following misleading messages to be printed:

[    1.443638] [drm:hdmi_probe] *ERROR* failed to get regulators
[    1.449326] [drm:hdmi_probe] *ERROR* hdmi_resources_init failed

Don't use the vrefresh field of the DRM mode since this
one is supposed to only be used for debug purpose.
Instead use the clock field which should also provide
much more precise information.

Also sanitize the case in which the clock value
should be zero. We then just default to the maximum
clock divisor.

Driver code did not remove event from the list of pending events before destroy.
As a result drm core later tried to inspect invalid memory location.
The patch replaces removal code with call to core helper.

not much new stuff this time. A (micro-)optimization to allow the
hangcheck timer to be coalesced with other wakeups in the system and a
fix to handle mmaping of prime imported and userptr buffers correctly. I
don't think we have seen any actual issues going back to this yet, so I
figured it's safer to get this in via drm-next rather than smashing it
into fixes.
