dwc_otg: Support switch host and device directly via sysfs.

BZ: 31708

Currently, the sysfs interface can't support switch HOST to DEVICE or
DEVICE to HOST directly. We have to restart whole HVP platform to do
this switch. There are two patches to fix this issue, this patch is for
host side fixing.

hsi_ffl_tty: increase modem boot timeout to 60 seconds as per IMC request

BZ: 28292

The modem post boot handshake timeout is currently set to 10 seconds, which
seems to be sufficient a time for the modem to setup its HSI IPC. But, this
assertion is not true and the modem can take up to one minute to boot up.

This patch is simply increasing the modem boot timeout to 60 seconds instead
of 10 seconds to allow correct modem reboot handshake in all contexts.

Still, this timeout value shall be fine tuned when the modem firmware will be
allowing shorter boot sequences - one minute seems huge for setting up the IPC.

SMP: blocked at csd_lock when bringing up the non-boot CPUs during waking up from suspend state

BZ: 26556

When system wake up from suspend state, sometimes the Jack interrrupt is comming
quickly and the corresponding irq thread snd_mfld_codec_intr_detection will call
ipc_command, which will call smp_call_function at last.

The call trace is like below:
snd_mfld_codec_intr_detection -->
sn95031_jack_detection -->
snd_soc_update_bits -->
snd_soc_read -->
sn95031_read -->
... -->
ipc_command -->
pm_qos_update_request -->
... -->
smp_call_function

At the same time, the suspend worker thread is bringing up the non-boot CPUs
(just only one on our platform).
The call trace is like below:
pm_suspend -->
suspend_devices_and_enter -->
enable_nonboot_cpus -->
_cpu_up -->
native_cpu_up

At this step, the second CPU is running start_secondary, and have set the
cpu online flag. In smp_call_function_single, it will send an IPI and waiting
for csd_unlock, but in some race conditions, the IPI message do not handled by
second CPU maybe due to the irq is still in disabled state.

THe solution is waiting for the second CPU gone into active status, then send the IPI
command to the second CPU.

Board files for different platforms have lot of common code, hence
to avoid code duplication we have re-factored the current board

For each device we have created a separate platform_*device_name*.c,h
files.

platform_*device_name*.c - Contains device init and helper
   functions.
platform_*device_name*.h - Contains extern declaration of init
   function.

Compilation of these platform files is controlled using corresponding
driver CONFIG options.

To use these devices, In board files we will have to just include the
header file and add reference to the device init function in the
device_id structure.

Mt9e013: Set sensor pixel rate clk to 96MHz

BZ: 27683

ISP work frequency is only 200MHz on Lexington board.
High sensor pixel rate doesn't give enough OTF processing time
for ISP. This patch will decrease sensor pixel rate to 96MHz
and make ISP can work OTF.

Revert "[PORT FROM R2]audio: sn95031: modify PCM2"

BZ: 30843

This reverts commit ce35adf759aab6fcc13754eb8db020a41d531c6b.

The patch reverted here causing some crackling noise issues.
The reverted patch was wrongly enabling PCM2 during voice
call.  The simultaneous enabling of both PCM2 and PCM1 during
voice call might cause crackling noise.

Fix the error by reverting patch #38989. This patch was added
to address the PCM2 enabling sequence as per the spec.  Reverting
the patch would not cause any functionality difference.

Audio: use LLI dma transfer for audio firmware download.

BZ: 25658

Currently firmware is downloaded through single block dma mode.
This causes sst driver to submit block by block.

Add support for LLI (Linked list item also known as multi block) DMA transfer
in which driver can submit multiple DMA descriptor and then initiated
DMA just in one trigger. This will use DMA engine's capability effectively
thus reducing the time consumed in downloading the audio firmware.

This patch implements memory to memory LLI transfer mechanism in DMA driver
and modifies the SST driver to use the LLI capability.

hdmi-audio:mark the alsa ring buffer memory as uncached

BZ: 29792

When mmap method of driver is called, driver remaps
the buffers to user space using remap_pfn_range().
However this doesn't guaranteed to mark the pages
as non-cacheble.

As per Documentation/x86/pat.txt, if RAM region is
mmap'ed then in addition remap_pfn_range() we need to use
set_memory_uc() for marking pages as uncacheble.

lm3554: fix the usage of the gpio API

[PORT FROM R2] atomisp: acc: use vmalloc() when loading/allocating acceleration firmware

BZ: 23757

Currently acceleration API tries to allocate memory for loaded firmware
with kmalloc(). As such firmwares used to be bigger than PAGE_SIZE,
kmalloc() may get in trouble if memory is too fragmented. vmalloc() is a
safer option.

atomisp: hmm: allow sleep when alloc_private_pages() is trying order == 0

BZ: 27472

For performance purpose, alloc_private_pages() tries to allocate pages
without allowing to sleep. But such approach may fail when system isn't
yet running out of memory.
This patch allows alloc_pages() to sleep when page order == 0, which
happens after a bigger order failed in atomic mode or even in case it was
the original requested order.
