Move 'compatible' line out of the common am335x.dtsi and into the beaglebone-specific .dts file. Add a new .dts for the BeagleBone Black with more memory, slightly different pinmux initialization, and with mmchs1 configured (though the latter doesn't quite work yet).

Switch TI platform support code from using FreeBSD's custom-baked DTS files to vendor-provided ones. It should make easier to adopt platform code to new revisions of hardware and to use DTS overlays for various Beaglebone extensions (shields/capes). Original dts filenames were not changed, they're now wrappers over dts files provided by TI. So make sure you update .dtb files on your devices as part of kernel update GPIO addressing was changed: instead of one global /dev/gpioc0 there are per-bank instances of /dev/gpiocX. Each bank has 32 pins so for instance pin 121 on /dev/gpioc0 in old addressing scheme is now pin 25 on /dev/gpioc3 On Pandaboard serial console devices was changed from /dev/ttyu0 to /dev/ttyu2 so you'll have to update /etc/ttys to get login prompt on serial port in multiuser mode. Single user mode serial console should work as-is Differential Revision: https://reviews.freebsd.org/D2146 Reviewed by: rpaulo, ian, Michal Meloun, Svatopluk Kraus

Add HDMI support to Beaglebone Black: - Add driver for TDA19988 HDMI framer - Add simple interface to communicate with HDMI sink: read EDID and set videomode - Add event-based API to notify LCD controller when HDMI sink is available - Add HDMI framer node and add refernce to it to lcdc node. This part of DTS tree is custom and does not match Linux DTS because Linux uses combination of pseudo-node in DTS and hardcoded driver information that does not map to our model.

Enable both i2c1 and i2c2. These devices are disabled in TI's DTS so they were disabled during DTS transition. Though there are no standard devices/drivers on them people might use iic(4) userland interface to access these buses.

Use the AM33XX_IOPAD() MACRO which is easier to read (uses the same offset of TRM). While here remove i2c2_pins, it is already defined in am335x-bone-common.dtsi. Sponsored by: Rubicon Communications (Netgate)
