David Lechner 17d8bacf19 clk: davinci: da850-pll: change PLL0 to CLK_OF_DECLARE
PLL0 on davinci/da850-type device needs to be registered early in boot
because it is needed for clocksource/clockevent. Change the driver
to use CLK_OF_DECLARE for this special case.

David Lechner 76c9dd9dbd clk: davinci: pll: allow dev == NULL
This modifies the TI Davinci PLL clock driver to allow for the case
when dev == NULL. On some (most) SoCs that use this driver, the PLL
clock needs to be registered during early boot because it is used
for clocksource/clkevent and there will be no platform device available.

David Lechner 2d17269151 clk: davinci: New driver for davinci PLL clocks
This adds a new driver for mach-davinci PLL clocks. This is porting the
code from arch/arm/mach-davinci/clock.c to the common clock framework.
Additionally, it adds device tree support for these clocks.

The ifeq ($(CONFIG_COMMON_CLK), y) in the Makefile is needed to prevent
compile errors until the clock code in arch/arm/mach-davinci is removed.

Note: although there are similar clocks for TI Keystone we are not able
to share the code for a few reasons. The keystone clocks are device tree
only and use legacy one-node-per-clock bindings. Also the register
layouts are a bit different, which would add even more if/else mess
to the keystone clocks. And the keystone PLL driver doesn't support
setting clock rates.
