This patch debounces hotplug interrupts generated by the HDMI hotplug
gpio. The reason this is needed is that we get multiple (5) interrupts
every time a monitor is inserted which causes us to needlessly enable
and disable the IP block.

This patch removes the hdmiphy reset in hdmi_poweroff. The hdmiphy reset
was added to take advantage of exynos clockgating, doing it would gate
the entire TV domain. Unfortunately, mixer is included in the TV domain
and its vsync interrupts are stopped when TV is gated.

The recent commit [3ea87855: drm/helper: lock all around force mode

Certain bridge chips use a GPIO to indicate the cable status instead
of the I_DP_HPD pin. This adds an optional device-tree property,
"samsung,hpd-gpio", to the exynos-dp controller which indicates that
the specified GPIO should be used for hotplug detection.
The GPIO is then set up as an edge-triggered interrupt where the
rising edge indicates hotplug-in and the falling edge indicates hotplug-out.

AFAICT, the fb_base of a drm_device's mode_config is never used. It isn't
accessed by core drm, it isn't used by fbmem, and it isn't exposed to user
space.
Furthermore, it is probably supposed to be a physical address, not the
dma address mapped to the display controller, so this is just wrong.

Kernel access to the eyxnos fbdev framebuffer is via its gem object's
kernel mapping (kvaddr, stored in info->screen_base).
User space access is provided by mmap(), read() and write() of /dev/fb/fb0.
These functions also only use screen_base/screen_size().
Therefore, it is not necessary to set fix->smem_{start,len} or
fix->mmio_{start,len} fields.
This avoids leaking kernel, physical and dma mapped addresses to user
space via the ioctls FBIOGET_VSCREENINFO and FBIOGET_FSCREENINFO.

In cyclic dma tx's handler sdma_handle_channel_loop(),
SDMA channel statue is set to either DMA_ERROR or DMA_IN_PROGRESS
based on each period's status. This has the following issues:
1) If one period's status is BD_RROR, then channel status
will be set to DMA_ERROR, but it will be overwritten to DMA_IN_PROGRESS
if the following periods are OK.
2) DMA client may call sdma_control(DMA_TERMINATE_ALL) to stop the cyclic dma
operation, sdma channel status will be set to DMA_ERROR,
but if after this handler is called, then again the channel status will be overwritten
to DMA_IN_PROGRESS. Then the following dmaengine_prep_dma_cyclic() will always fail,
as channel status is DMA_IN_PROGRESS.
As in cyclic dma tx, channel status will be initially set to DMA_IN_PROGRESS,
driver only needs to change it to DMA_ERROR, when something wrong happens
(one period status is wrong, or stoped by client explicitly).

The baudclock may be used and set by different streams.
Allow only the first stream to set the bitclock rate. Other streams have
to try to get to the correct rate without modifying the bitclock rate
using the SSI internal clock modifiers.
The variable baudclk_streams is introduced to keep track of the active
streams that are using the baudclock. This way we know if the baudclock
may be set and whether we may enable/disable the clock.
baudclock enable/disable is moved to hw_params()/hw_free(). This way we can
keep track of the baudclock in those two functions and avoid a running
clock while it is not used. As hw_params()/hw_free() may be called
multiple times for the same stream, we have to use baudclk_streams
variable to know whether we may enable/disable the clock.

Due to recent changes to the way that the MITM requirement is set for
outgoing pairing attempts we can no longer rely on the hcon->auth_type
variable (which is actually good since it was formed from BR/EDR
concepts that don't really exist for SMP).
To match the logic that BR/EDR now uses simply rely on the local IO
capability and/or needed security level to set the MITM requirement for
outgoing pairing requests.
