Subject: gpu: ipu-v3: Implement use counter for ipu_dc_enable(),
 ipu_dc_disable()

The functions ipu_dc_enable() and ipu_dc_disable() enable/disable the DC
globally in the IPU_CONF register, but the DC is used by multiple clients
on different DC channels. So make sure to only disable/enable the DC
globally based on a use counter.

drm driver may probe before the i2c bus, so the driver should
defer probing until it is available

Subject: drm: imx: imx-hdmi: convert imx-hdmi to drm_bridge mode

IMX6 and Rockchip RK3288 and JZ4780 (Ingenic Xburst/MIPS)
use the interface compatible Designware HDMI IP, but they
also have some lightly differences, such as phy pll configuration,
register width, 4K support, clk useage, and the crtc mux configuration
is also platform specific.

To reuse the imx hdmi driver, convert it to drm_bridge

handle encoder in imx-hdmi_pltfm.c, as most of the encoder
operation are platform specific such as crtc select and
panel format set

This patch depends on Russell King's patch:
 drm: imx: convert imx-drm to use the generic DRM OF helper

Subject: drm: imx: imx-hdmi: move imx-hdmi to bridge/dw_hdmi

the original imx hdmi driver is under drm/imx/,
which depends on imx-drm, so move the imx hdmi
driver out to drm/bridge and rename it to dw_hdmi

Subject: drm: bridge/dw_hdmi: add support for multi-byte register width access

On rockchip rk3288, only word(32-bit) accesses are
permitted for hdmi registers.  Byte width accesses (writeb,
readb) generate an imprecise external abort.

Subject: drm: bridge/dw_hdmi: clear i2cmphy_stat0 reg in
 hdmi_phy_wait_i2c_done

HDMI_IH_I2CMPHY_STAT0 is a clear on write register, which indicates i2cm
operation status(i2c transfer done or error), every hdmi phy register
configuration must check this register to make sure the configuration
has complete. But the indication bit should be cleared after check, otherwise
the corresponding bit will hold on forever, this may give a wrong signal for
next check.

Subject: gpu: ipu-di: Add ipu_di_adjust_videomode()

On some monitors, high resolution modes are not working, exhibiting
pixel column truncation problems (for example, 1280x1024 displays as
1280x1022).

The function ipu_di_adjust_videomode() aims to fix these issues by
adjusting a passed videomode to IPU restrictions. The function can
be called from the drm_crtc_helper_funcs->mode_fixup() methods.

Subject: imx-drm: ipuv3-crtc: Implement mode_fixup

Ask the IPU display interface, via ipu_di_adjust_videomode(), to
adjust a video mode to meet any DI restrictions. The function takes
a subsystem independent videomode, so the drm_display_mode must be
converted to videomode first, and then the adjusted mode converted
back to a drm_display_mode.

Subject: gpu: ipu-di: Switch to DIV_ROUND_CLOSEST for DI clock divider calc

We can use the DIV_ROUND_CLOSEST() macro when calculating the DI
clock divider, rounded to nearest int.

Subject: imx-drm: core: handling of DI clock flags to ipu_crtc_mode_set()

We do not need to track the state of the IPU DI's clock flags by having
each display bridge calling back into imx-drm-core, and then back out
into ipuv3-crtc.c.

ipuv3-crtc can instead just scan the list of encoders to retrieve their
type, and build up a picture of which types of encoders are attached.
We can then use this information to configure the IPU DI clocking mode
without any uncertainty - if we have multiple bridges connected to the
same DI, if one of them requires a synchronous DI clock, that's what we
must use.
