a7f7f6248d treewide: replace '---help---' in Kconfig files with 'help'
Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

2630e1bb09 media: rkvdec: Fix H264 scaling list order
The Rockchip Video Decoder driver is expecting that the values in a
scaling list are in zig-zag order and applies the inverse scanning process
to get the values in matrix order.

Commit 0b0393d59e ("media: uapi: h264: clarify expected
scaling_list_4x4/8x8 order") clarified that the values in the scaling list
should already be in matrix order.

Fix this by removing the reordering and change to use two memcpy.

a8876c22ea media: cedrus: Program output format during each run
Previously, the output format was programmed as part of the ioctl()
handler. However, this has two problems:

  1) If there are multiple active streams with different output
     formats, the hardware will use whichever format was set last
     for both streams. Similarly, an ioctl() done in an inactive
     context will wrongly affect other active contexts.
  2) The registers are written while the device is not actively
     streaming. To enable runtime PM tied to the streaming state,
     all hardware access needs to be moved inside cedrus_device_run().

The call to cedrus_dst_format_set() is now placed just before the
codec-specific callback that programs the hardware.

387041cda4 media: atomisp: improve sensor detection code to use _DSM table
Instead of keep hardcoding device-specific tables, read them
directly from the ACPI BIOS, if available.

This method is know to work with Asus T101HA device. the
same table is also visible on EzPad devices. So, it seems
that at least some BIOSes use this method to pass data about
ISP2401-connected sensors.

69a03e36c7 media: atomisp: get rid of an iomem abstraction layer
The hive_isp_css_custom_host_hrt.h code, together
with atomisp_helper.h, provides an abstraction layer for
some functions inside atomisp_compat_css20.c and atomisp_cmd.c.

There's no good reason for that. In a matter of fact, after
removing the abstraction, the code looked a lot cleaner
and easier to understand.

So, get rid of them.

While here, get rid also of the udelay(1) abstraction code.

17c3827b4c media: atomisp: don't set hpll_freq twice with different values
The logic which sets the hpll_freq for BYT sets hpll_freq

of 2000MHz).

Remove the first set, as this will be overriden anyway.

c371af6869 media: atomisp: get rid of a detection hack for a BYT Andorid-based tablet
There's a hack at the driver that selects a different table
for a BYT tablet, which sets the maximum frequency to 320 MHz,
instead of 400 MHz.

After looking at the Intel Aero Yocto's version from:

	https://download.01.org/aero/deb/pool/main/l/linux-4.4.76-aero-1.3/

It was noticed that this depends on an Android-specific modprobe parameter,
which uses a macro (INTEL_MID_BOARD) from this file:

	arch/x86/include/asm/spid.h

>From the comments there, it looks like this macro parses a
variable passed at boot time:

	cmdline : androidboot.spid=vend:cust:manu:plat:prod:hard

The devices in question are identified there as:

	INTEL_BYT_TABLET_BLK_PRO = 0x0000
	INTEL_BYT_TABLET_BLK_ENG = 0x8000

Well, this is something that we don't have upstream. So,
without further details about that, we can't really parse it.

If we ever end supporting those devices with the upstream driver,
this patch can be reverted and the device can be detected
via DMI (or maybe via PCI ID?).

        { MEDIA_BUS_FMT_JPEG_1X8, 8, 8, CSS_FRAME_FORMAT_BINARY_8, 0, ATOMISP_INPUT_FORMAT_BINARY_8 },

Checking the git history, I found a commit that disabled one such case
because it did not work. It seems likely that the incorrect enum was
part of the original problem and that the others do not work either,
or have never been tested.

Disable all the ones that cause a warning.

INPUT_SYSTEM0_ID is zero, so use the corresponding zero-value
of the expected types instead.

09013efe1c media: staging: atomisp: Fix atomisp_overlay32 compat handling
The struct atomisp_overlay contains overlay_start_x and overlay_start_y
fields. Instead of copying the value of the overlay_start_x field between
the two structs, the value of the overlay_start_y field of the compat
struct was copied to the overlay_start_x field of the 64-bit kernel struct
in get operation and back in put. The overlay_start_x field value was not
copied from or to the user space struct.

Fix this so that the value of overlay_start_x is copied to overlay_start_x
and the value of overlay_start_y is copied to overlay_start_y.

Also do copy blend_overlay_perc_u field only once.
