Add a driver for the EMIF SDRAM controller used in TI SoCs
EMIF is an SDRAM controller that supports, based on its revision,
one or more of LPDDR2/DDR2/DDR3 protocols.This driver adds support
for LPDDR2.
The driver supports the following features:
- Calculates the DDR AC timing parameters to be set in EMIF
registers using data from the device data-sheets and based
on the DDR frequency. If data from data-sheets is not available
default timing values from the JEDEC spec are used. These
will be safe, but not necessarily optimal
- API for changing timings during DVFS or at boot-up
Is this a kernel/user API, or just an in-kernel API?
That's just an in-kernel API or more precisely callbacks to be
registered for DDR frequency change events.
thanks,
Aneesh
