Merge tag 'for-v3.19/omap-b2' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.19/soc

Several more OMAP patches targeted for v3.19. They include:

- OMAP4/5: DSS hwmod cleanup patches from Tomi Valkeinen.
- DRA7xx: hwmod data support for UARTs 7 through 10.
- AM43xx: hwmod data support for the onboard ADC.

Basic build, boot, and PM test reports are here:

Note that I cannot test the DRA7xx or AM43xx patches, since I do not have
these boards.
