The first patch fixes a device tree bug that's been around for a while. Unfortunately any systems shipped with the buggy device will stop booting once they switch to the new clocksource driver. Patch 2 adds a new clocksource driver for davinci. Patch 3 enables the new driver for device-tree based systems. Patches 4-9 add a WARN() to the machine code of all davinci boards which is triggered if clk_get() for the timer clock fails. This is needed as the new driver expects the clock to be functional and doesn't check it. Patches 10-11 and 13-16 switch the board files to using the new clocksource driver while patch 12 moves some necessary defines to a different place since we'll be removing the file that contains them. Patch 17 removes legacy timer code.
