Pinning fbdev's FB at the start of VRAM prevents X from pinning
its FB. Since for ldu, the fb would be pinned anyway during a
mode set, just skip pinning it in fbdev.
This is not the best solution, but since ldu is not used much
anymore, it seems like a reasonable workaround.

We can no longer make the assumption that vmw_stdu_update_st() will

instead of using display_srf for width and height, make a record of

Switch over to using internal atomic API for mode set.
This removes the legacy set_config API, replacing it with
drm_atomic_helper_set_config(). The DRM helper will use various
vmwgfx-specific atomic functions to set a mode.
DRIVER_ATOMIC capability flag is not yet set, so the user mode
will still use the legacy mode set IOCTL.
v2:
* Avoid a clash between page-flip pinning and setcrtc pinning, modify
the page-flip code to use the page-flip helper and the atomic callbacks.
To enable this, we will need to add a wrapper around atomic_commit.

The reference manual for the i.MX28 recommends to calculate the divisor
as
divisor = (UARTCLK * 32) / baud rate, rounded to the nearest integer
, so let's do this. For a typical setup of UARTCLK = 24 MHz and baud
rate = 115200 this changes the divisor from 6666 to 6667 and so the
actual baud rate improves from 115211.521 Bd (error ≅ 0.01 %) to

Commit 4cfffcfa51 ("irqchip/mips-gic: Fix local interrupts") added
mapping of several local interrupts during initialisation of the gic
driver. This associates virq numbers with these interrupts.
Unfortunately, as not all of the interrupts are mapped in hardware
order, when drivers subsequently request these interrupts they conflict
with the mappings that have already been set up. For example, this
manifests itself in the gic clocksource driver, which fails to probe
with the message:
clocksource: GIC: mask: 0xffffffffffffffff max_cycles: 0x7350c9738,
max_idle_ns: 440795203769 ns
GIC timer IRQ 25 setup failed: -22
This is because virq 25 (the correct IRQ number specified via device
tree) was allocated to the PERFCTR interrupt (and 24 to the timer, 26 to
the FDC). To fix this, map all of these local interrupts in the hardware
order so as to associate their virq numbers with the correct hw
interrupts.

After consulting with Dell, they told us this machine doesn't support
microphone via headset jack, so we add a new fixup which only defines
the pin 0x18 as the headset-mic.
[rearranged the fixup insertion position by tiwai in order to make the
merge with other branches easier -- tiwai]

MCA bank 3 is reserved on systems pre-Fam17h, so it didn't have a name.
However, MCA bank 3 is defined on Fam17h systems and can be accessed
using legacy MSRs. Without a name we get a stack trace on Fam17h systems
when trying to register sysfs files for bank 3 on kernels that don't
recognize Scalable MCA.
Call MCA bank 3 "decode_unit" since this is what it represents on
Fam17h. This will allow kernels without SMCA support to see this bank on
Fam17h+ and prevent the stack trace. This will not affect older systems
since this bank is reserved on them, i.e. it'll be ignored.
Tested on AMD Fam15h and Fam17h systems.

As reported in STAR 9001165532, an SLC control reg read (for checking
busy state) right after SLC invalidate command may incorrectly return
NOT busy causing software to NOT spin-wait while operation is underway.
(and for some reason this only happens if L1 cache is also disabled - as
required by IOC programming model)
Suggested workaround is to do an additional Control Reg read, which
ensures the 2nd read gets the right status.

On MacBook Pros introduced 2011 and onward, external DP ports are
combined DP/Thunderbolt ports that are no longer fully switchable
between GPUs, they can only be driven by the discrete GPU.
More specifically, the Main Link pins (which transport the actual video
and audio streams) are soldered to the discrete GPU, whereas the AUX
Channel pins are switchable. Because the integrated GPU is missing the
Main Link, external displays appear to it as phantoms which fail to
link-train.
Force the AUX channel to the discrete GPU on these models to avoid any
confusion. Document the switching policy implemented by this commit.

An external Thunderbolt GPU can neither drive the laptop's panel nor be
powered off by the platform, so there's no point in registering it with
vga_switcheroo. In fact, when the external GPU is runtime suspended,
vga_switcheroo will cut power to the internal discrete GPU, resulting in
a lockup.
