* arm:am33xx: Add a scale_vcores() hookTom Rini2014-06-06-0/+1
| | | | | | | Similar to OMAP4/5 we need to scale the voltage up prior to changing the clock frequencies up higher. Add a similar hook to start with. Signed-off-by: Tom Rini <trini@ti.com>

* ARM: AM43xx: clocks: Update DPLL detailsLokesh Vutla2013-12-18-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Updating the Multiplier and Dividers value for all DPLLs. Safest OPP is read from DEV ATTRIBUTE register. Accoring to the value returned the MPU DPLL is locked. At different OPPs follwoing are the MPU locked frequencies. OPP50 300MHz OPP100 600MHz OPP120 720MHz OPPTB 800MHz OPPNT 1000MHz According to the latest DM following is the OPP table dependencies: VDD_CORE VDD_MPU OPP50 OPP50 OPP50 OPP100 OPP100 OPP50 OPP100 OPP100 OPP100 OPP120 So at different OPPs of MPU it is safest to lock CORE at OPP_NOM. Following are the DPLL locking frequencies at OPP NOM: Core locks at 1000MHz Per locks at 960MHz LPDDR2 locks at 266MHz DDR3 locks at 400MHz Touching AM33xx files also to get DPLL values specific to board but no functionality difference.

* ARM: AM33xx: Cleanup clocks layerLokesh Vutla2013-08-15-2/+26
| | | | | | | | | | | 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 Vutla2013-08-15-0/+70
| | | | | | | | | | | | | 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.
