* am335x:Handle worst case scenario for Errata 1.0.24Steve Kipisz2013-09-20-2/+6
| | | | | | | | | | | | | In Errata 1.0.24, if the board is running at OPP50 and has a warm reset, the boot ROM sets the frequencies for OPP100. This patch attempts to drop the frequencies back to OPP50 as soon as possible in the SPL. Then later the voltages and frequencies up set higher.

* ARM: AM33xx: Cleanup clocks layerLokesh Vutla2013-08-15-197/+78
| | | | | | | | | | | Cleaning up the clocks layer. This helps in addition of new Soc with minimal changes. This is derived from OMAP4 boards. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Tested-by: Heiko Schocher <hs@denx.de> Acked-by: Heiko Schocher <hs@denx.de>
* ARM: AM33xx: Cleanup dplls dataLokesh Vutla2013-08-15-182/+38
| | | | | | | | | | | | | Locking sequence for all the dplls is same. In the current code same sequence is done repeatedly for each dpll. Instead have a generic function for locking dplls and pass dpll data to that function. This is derived from OMAP4 boards.
