Add basic cpuidle support for AM33XX family of SoC.
Right now only two idle states (WFI and WFI+SR) are
supported. The latency/residency numbers chosen will
be fine-tuned based on power measurements on actual
hardware.Signed-off-by: Vaibhav Bedia

TI processors in TI81x and AM33x family work with PMICs like
TPS65910/1 which are not part of the TWL series. These processors
also do not have a voltage controller/processor module.In order to invoke the normal regulator calls from the voltage
layer the following changes are done to struct voltagedomain
- Add a flag use_regulator for the SoC voltagedomain
code to indicate its intention of using a PMIC which
is not controlled by VC/VP
- Add a regulator_init callback which the platform code
can utilise for any custom init sequence before making
use of the regulator. Platform code is also expected
to set the voltdm->scale function in the init callbackSigned-off-by: Ravikumar Kattekola

This patch is added to route CPSW interrupts through ICSS module.
CPSW CPSW_RX and CPSW_TX interrupts are not directly used from CPSW
and instead they are routed through Timer module. This is done as an
software workaround for enabling interrupt pacing feature. As interrupt
Pacing works on C0_RX_PULSE interrupt connection to A8 INTC, which is
not connected to Cortex A8 interrupt controller directly due to hw issue,
it prevents interrupt pacing to work in AM33xx EVM. Therefore, Timer
capture module is used to pickup these interrupts and routed to A8 INTC.Signed-off-by: Chandan Nath

- New IP has separate hw registers to detect card insertion/removal &

- Currently code support max segs of 1
- uses different registr bit to identify dma completion errors

We have two SoCs using SRAM, both with their own allocation systems,
and both with their own ways of copying functions into the SRAM.Let's unify this before we have additional SoCs re-implementing this
obviously common functionality themselves.For this use the generic allocator and the newly introduce
gen_pool_add_virt and gen_pool_virt_to_physUio_pruss should probably take the SRAM pool pointer via
platform data so that it doesn't have to include Davinci specific
includes.Signed-off-by: Russell King
