6f62bda1ea drm/i915: Fix 400 MHz FSB readout on elk
Looks like elk redefines some of the CLKCFG FSB values to
make room for 400 MHz FSB. The setting overlaps with one of
the 266MHz settings (which is even documented in the ctg docs,
and cofirmed to be correct on my ctg). So we limit the special
case to elk only.

Though it might also be that we have some kind of desktop vs.
mobile difference going on here as eg. both g35 and elk
use 0x0 for the 266 MHz setting, vs. 0x6 used by ctg). The
g35 doesn't let me select 400MHz for the FSB strap so can't
confirm which way it would go here. But anyways as it seems
only elk has the 400MHz option we shouldn't lose anything
by limiting the special case to it alone.

My earlier experiments on this appear to have been nonsense as
the comment I added claims that FSB strap of 400MHz results in
a value of 0x4, but I've now retested it and I definitely get a
value of 0x6 instead. So let's remove that bogus comment.

v2: s/_ELK/_ALT/ in the define in anticipation of a full
    mobile vs. desktop CLKCFG split

6c4bcd8a46 efi/printf: Refactor code to consolidate padding and output
Consolidate the actual output of the formatted text into one place.

Fix a couple of edge cases:
1. If 0 is printed with a precision of 0, the printf specification says
   that nothing should be output, with one exception (2b).
2. The specification for octal alternate format (%#o) adds the leading
   zero not as a prefix as the 0x for hexadecimal is, but by increasing
   the precision if necessary to add the zero. This means that
   a. %#.2o turns 8 into "010", but 1 into "01" rather than "001".
   b. %#.o prints 0 as "0" rather than "", unlike the situation for
      decimal, hexadecimal and regular octal format, which all output an
      empty string.

Reduce the space allocated for printing a number to the maximum actually
required (22 bytes for a 64-bit number in octal), instead of the 66
bytes previously allocated.

913ec479bb drm/mgag200: Replace VRAM helpers with SHMEM helpers
The VRAM helpers managed the framebuffer memory for mgag200. This came
with several problems, as some MGA device require the scanout address
to be located at VRAM offset 0. It's incompatible with the page-flip
semantics of DRM's atomic modesettting. With atomic modesetting, old and
new framebuffers have to be located in VRAM at the same time. So at least
one of them has to reside at a non-0 offset.

This patch replaces VRAM helpers with SHMEM helpers. GEM SHMEM buffers
reside in system memory, and are shadow-copied into VRAM during page
flips. The shadow copy always starts at VRAM offset 0.

uses device-specific macros.

The original implementation busy-waited for the VSYNC flag to go
up, to synchronize the page flip with the display's vblank. This
code has been moved to mga_crtc_mode_set_base(). It's still present
in the non-atomic code paths, but won't be used in atomic commits.
With atomic, we should use interrupts to synchronize with vblanks.

v3:
	* clarify commit message wrt. vblank busy-waiting
v2:
	* use to_mga_device()
	* use MiB instead of MB
	* replace empty while loop with do-while, fixes checkpatch warning
	* replace uint{8,32}_t with u{8,32}

5a77e2bfdd drm/mgag200: Remove HW cursor
The HW cursor of Matrox G200 cards only supports a 16-color palette
format. Univeral planes require at least ARGB or a similar component-
based format, so remove the HW cursor.

Alternatively, the driver could dither a cursor image from ARGB to
16 colors. But this does not produce pleasent-looking results in
general, so it's useless for modern compositors.

Without HW support, compositors will use software rendering.

fd0528a249 efi/libstub: Buffer output of efi_puts
Use a buffer to convert the string to UTF-16. This will reduce the
number of firmware calls required to print the string from one per
character to one per string in most cases.

Cast the input char to unsigned char before converting to efi_char16_t
to avoid sign-extension in case there are any non-ASCII characters in
the input.

7ceaa40b93 soundwire: bus_type: add sdw_master_device support
In the existing SoundWire code, Master Devices are not explicitly
represented - only SoundWire Slave Devices are exposed (the use of
capital letters follows the SoundWire specification conventions).

With the existing code, the bus is handled without using a proper device,
and bus->dev typically points to a platform device. The right thing to
do as discussed in multiple reviews is use a device for each bus.

The sdw_master_device addition is done with minimal internal plumbing
and not exposed externally. The existing API based on
sdw_bus_master_add() and sdw_bus_master_delete() will deal with the
sdw_master_device life cycle, which minimizes changes to existing
drivers.

Note that the Intel code will be modified in follow-up patches (no
impact on any platform since the connection with ASoC is not supported
upstream so far).

If 'thermal_cooling_device_register()' fails, we must undo what has been
allocated so far. So we must go to 'err_thermal_destroy' instead of
returning directly

In case of error in 'ath11k_thermal_register()', the previous
'thermal_cooling_device_register()' call must also be undone. Move the
'ar->thermal.cdev = cdev' a few lines above in order for this to be done
in 'ath11k_thermal_unregister()' which is called in the error handling
path.

df00731cff usb: xhci: fix USB_XHCI_PCI depends
The xhci-pci-renesas module exports symbols for xhci-pci to load the
RAM/ROM on renesas xhci controllers. We had dependency which works
when both the modules are builtin or modules.

But if xhci-pci is inbuilt and xhci-pci-renesas in module, we get below
linker error:
drivers/usb/host/xhci-pci.o: In function `xhci_pci_remove':
drivers/usb/host/xhci-pci.c:411: undefined reference to `renesas_xhci_pci_exit'
drivers/usb/host/xhci-pci.o: In function `xhci_pci_probe':
drivers/usb/host/xhci-pci.c:345: undefined reference to `renesas_xhci_check_request_fw'

Fix this by adding USB_XHCI_PCI having depends on USB_XHCI_PCI_RENESAS
|| !USB_XHCI_PCI_RENESAS so that both can be either inbuilt or modules.
