This adds the new USB PHY clock init in mach-davinci/usb-da8xx.c using
the new common clock framework drivers.
The #ifdefs are needed to prevent compile errors until the entire
ARCH_DAVINCI is converted.
Signed-off-by: David Lechner <david@xxxxxxxxxxxxxx>
---
v8 changes:
- rebased on "ARM: davinci: DA8XX: fix oops in USB PHY driver due to stack
allocated platform platform_data"
v7 changes:
- register platform device instead of registering clocks directly
- USB PHY clocks now treated as single device instead of registering them
separately
v6 changes:
- rename stuff to match changes in "clk: davinci: New driver for TI DA8XX USB
PHY clocks"
- take advantage of syscon lookup changes in "mfd: syscon: Add syscon_register()
function"
