Hi,

No, don't pull this, it doesn't work.

Paul, the hwmod patch cannot be picked from the DRA7 DSS series. We have
the problem with the DES HDCP clock, without that clock we will see
WARNINGs when booting if the "set DSS submodule parent hwmods" is applied.

We do see some errors when booting even with the current mainline,
caused by not having that clock enabled:

[    0.194524] omap_hwmod: dss_core: _wait_target_disable failed
[    0.194540] omap_hwmod: dss_core: _wait_target_ready failed: -16
[    0.194554] omap_hwmod: dss_core: cannot be enabled for reset (3)
[    0.197143] omap_hwmod: dss_dispc: _wait_target_ready failed: -16
[    0.197156] omap_hwmod: dss_dispc: cannot be enabled for reset (3)
[    0.199745] omap_hwmod: dss_hdmi: _wait_target_ready failed: -16
[    0.199759] omap_hwmod: dss_hdmi: cannot be enabled for reset (3)

But that's still much less spam than the above plus ~4 WARNs.

I'd rather merge the DRA7 DSS patches in one go, to avoid issues related
to the HDPC clock.
