The dsi_pll_ops structure and dsi_init_pll_data() function incorrectly
use a dsi_ prefix, likely due to copy & paste. Fix it by using the
correct hdmi_ prefix.

The HDMI wrapper code only needs to differentiate between major OMAP
revisions, which can be obtained from the HDMI transmitter compatible
string. Replace the OMAP SoC model checks to prepare for removal of the
OMAP SoC version platform data.

The HDMI audio driver only needs to know which generation of HDMI
transmitter it deals with, not the detailed SoC model. Pass the version
number as an integer to prepare for removal of the OMAP SoC version from
the omapdrm driver.

The OMAP4 and OMAP5 PLLs have different properties that require specific
handling in the HDMI PLL driver. This needs knowledge of the PLL
version, which is currently inferred from the DSS version. AS part of
the effort to remove usage of the DSS version, use the HDMI controller
version instead.

There's no need to allocate memory dynamically to duplicate the contents
of a const structure, only to store the memory pointer in a const
pointer field. Just use the original structures directly.

The omapdrm platform device is a virtual device created for the sole
purpose of handling the omapdss/omapdrm driver split. It should
eventually be removed. As a first step to ease refactoring move its
registration from platform code to driver code.
The omapdrm driver name must be changed internally to avoid probing both
the device registered in platform code and the device registered in the
omapdss driver, as that would otherwise break bisection.

Changes since v1:
- Drop the CONFIG_DRM_OMAP conditional compilation
- Unregister the platform device at exit time

I trust that you have tested the patch with module unloading given that was
how you found the original issue :-)

Was there a reason to create the omapdrm device in omap_dss_init (i.e.
module_init), instead of omapdss's probe? Now the omapdrm device is
always created even if there's no DSS device on the SoC.

Not really, no.
Do you think this requires a quick -stable fix ? I'm working on a patch series
that will remove the omapdrm device completely.

With -stable, you mean 4.14? Afaics, the only downside is a small amount
of memory that's not used. It does behave differently than before, as
the now-removed platform code did only add the omapdrm device if there's
a dss device in the DT data. I don't think that really matters, though.
But still, maybe it's nice to fix for 4.14, as we're still only at -rc2.
We encountered this with TI kernel, which has DSS6 driver. The omapdrm
side is shared, but the dss side is different than with the current dss.
So, the dss6 driver needs to create omapdrm device, but old dss driver
already creates it...
We'll hack around it, as it's only an issue in a development kernel.
Tomi

The omapdss driver (not to be confused with the omapdss_dss driver) is
now a dummy driver with empty probe and remove functions. Remove it.

The omapdrm platform device is unused, as a replacement is now
registered in the omapdss driver. Remove it.

The omapdrm driver doesn't need the omapdss device anymore. Although it
can't be removed completely as the fbdev driver still requires it, we
can condition its registration to the usage of the omapfb driver.
