If two SSR drivers register with the same ramdump device pointing
at shared memory sysfs will complain about duplicate sysfs nodes:
WARNING: at fs/sysfs/dir.c:455 sysfs_add_one+0x78/0x98()
sysfs: cannot create duplicate filename

Avoid this case by making the names of the ramdump devices
unique via smem-$subsystem (smem-modem, smem-dsps, etc.).

PIL core code already calls shutdown on all processor during late
init, but we would like to remove that code. Therefore force GSS
into low power mode by explicitly calling the shutdown op during
driver probe. This achieves the same goal without requiring the
PIL core to call shutdown on all processors.

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.

as it give 8-bit data interface but timing closure for this slot is not
done for >100MHz clock on any of the existing chipsets (MSM8960, MSM8930
& APQ8064).
Since the timing closure is done till 100 MHz, we can enable HS200 mode
that runs at max. 100MHz. Recent performance measurements also indicate
that HS200 @96MHz (Clock plan supports max. 96MHz) gives better
performance than DDR@48MHz. So enable HS200 @96 MHz. On future targets
which get timing closed at ~200MHz, HS200 at that frequency will be
