Proprietary chargers pull D+/- to specific voltages between 2.0-3.3V
(VLGC) for identification. The DM voltage may not exceed VLGC due
to pull-down resistor. Hence a proprietary charger is detected as
a Standard downstream port (SDP). Read line state to distinguish
between SDP and proprietary charger. The DP voltage would exceed
VLGC for proprietary chargers.
D- can be greater than VLGC when a low speed device is attached via
Accessory charger adapter (ACA-A). Hence mark the charger as ACA-A
if ID resistance is RID_A and D- > VLGC

BUG_ON() may be appropriate for critical clock initialization that will
prevent proper booting, but it is not appropriate for functions called
in hotplug notifiers while bringing additional CPUs on line. There, it
is better to just fail the hotplug rather than crashing on purpose.
Fix this by cleaning up the initialization error paths so that functions
called in the hotplug path return errors and cleanly rollback state.

This patch adds support for CMA to dma-mapping subsystem for ARM
architecture. By default a global CMA area is used, but specific devices
are allowed to have their private memory areas if required (they can be
created with dma_declare_contiguous() function during board
initialisation).
Contiguous memory areas reserved for DMA are remapped with 2-level page
tables on boot. Once a buffer is requested, a low memory kernel mapping
is updated to to match requested memory access type.
GFP_ATOMIC allocations are performed from special pool which is created
early during boot. This way remapping page attributes is not needed on
allocation time.
CMA has been enabled unconditionally for ARMv6+ systems.

receive the sleep request at which point they can immediately transition
