This series adds a number of fixes and improvements to driver model as well as two new uclasses (video bridges and I2c muxes).
The series is aimed at adding support for spring (HP 11 Chromebook). Since it is very similar to other ARM Chromebooks, some effory is made to use common code rather than duplicating functionality. In fact spring uses the same code as several other boards, just with a different device tree and a few configuration changes. Audio works correctly on pit, pi, spring and snow with this series. A bug in the I2C driver broken this recently. The exynos implementation still has a few rough areas - e.g. some hard-coded GPIOs and the old-style SPL. Also it does not yet support CPU frequency scaling and power management. Spring has some oddities and they are hard to handle with U-Boot's old way of doing drivers. With driver model these can be implemented cleanly and this sort of problem was the original motivation for my interest in driver model. This series is available at u-boot-dm in branch spring-working. It is based on the previous set of driver model changes in branch clk-working.
