The FSL kernel detects the HDMI vendor id, and uses this to set
hdmi->edid_cfg.hdmi_cap, which is then used to set mdvi appropriately,
rather than detecting whether we are outputting a CEA mode. Update
the dw_hdmi code to use this logic, but lets eliminate the mdvi
variable, prefering the more verbose "hdmi->sink_is_hdmi" instead.
Use the generic drm_detect_hdmi_monitor() to detect a HDMI sink.

As mentioned in the previous commit, the dw-hdmi driver does not support
pixel doubled modes at present; it does not configure the PLL correctly
for these modes. Therefore, filter out the double-clocked modes as we
presently are unable to support them.

dw_hdmi sets a pixel repetition factor of 1 for VICs 10-15, 25-30 and
35-38. However, DRM uses their native resolutions in its timing
information. For example, VIC 14 can be 1440x480 with no repetition,
or 720x480 with one pixel repetition. As DRM uses 1440 pixels per line
for this video mode, we need no pixel repetition.
In any case, pixel repetition appears broken in dw_hdmi.

iMX6 devices suffer from an errata (ERR005174) where the audio FIFO can
be emptied while it is partially full, resulting in misalignment of the
audio samples.
To prevent this, the errata workaround recommends writing N as zero
until the audio FIFO has been loaded by DMA. Writing N=0 prevents the
HDMI bridge from reading from the audio FIFO, effectively disabling
audio.
This means we need to provide the audio driver with a pair of functions
to enable/disable audio. These are dw_hdmi_audio_enable() and
dw_hdmi_audio_disable().
A spinlock is introduced to ensure that setting the CTS/N values can't
race, ensuring that the audio driver calling the enable/disable
functions (which are called in an atomic context) can't race with a
modeset.

Clean up hdmi_set_clk_regenerator() by allowing it to take the audio

The phy configuration is dependent on the SoC, and we look up values for
some of the registers in SoC specific data. However, we had partially
programmed the phy before we had successfully looked up the clock rate.
Also, we were only checking that we had a valid configuration for the
currctrl register.
Move all these lookups to the start of this function instead, so we can
check that all lookups were successful before beginning to program the
phy.

Matthew Fortune <Matthew.Fortune@imgtec.com> reports:
The genex.S file appears to mix the case of a macro between its definition and
use. A cut down example of this is below. The macro __build_clear_none has
lower case 'build' but ends up being instantiated with upper case BUILD. Can
this be fixed on master. It has been picked up by the LLVM integrated assembler
which is currently case sensitive. We are likely to fix the assembler as well
but the code is currently inconsistent in the kernel.

This reverts commit:
2c7577a75837 ("sched/x86_64: Don't save flags on context switch")
It was a nice speedup. It's also not quite correct: SYSENTER
enables interrupts too early.
We can re-add this optimization once the SYSENTER code is beaten
into shape, which should happen in 4.3 or 4.4.

Allow the topology code to be compiled out so that users who don't need
topology don't need to havve the code compiled in, saving them some
memory.
Some more configuration could be added to remove some of the hooks into
the core data structures but that is probably best done with some
refactoring to use functions to do the updates of the data structures
rather than ifdefing in the code as we'd need to do at the minute.

VxLAN offloading is not functional if the NIC is running in multichannel
mode (UMC, FLEX-10, VNIC...). Enabling this additionally kills whole
connectivity through the NIC and the device needs to be down and up to
restore it. The firmware should take care about it and does not allow
the conversion of interface to tunnel type (be_cmd_manage_iface) or should
support VxLAN offloading if multichannel config is enabled.
I have tested this on the latest available firmware (10.6.144.21).

Martin KaFai Lau says:
====================
ipv6: Fix a potential deadlock when creating pcpu rt
v1 -> v2:
A minor change in the commit message of patch 2.
This patch series fixes a potential deadlock when creating a pcpu rt.
It happens when dst_alloc() decided to run gc. Something like this:
read_lock(&table->tb6_lock);
ip6_rt_pcpu_alloc()
=> dst_alloc()
=> ip6_dst_gc()
=> write_lock(&table->tb6_lock); /* oops */
Patch 1 and 2 are some prep works.
Patch 3 is the fix.

rt6_make_pcpu_route() is called under read_lock(&table->tb6_lock).
rt6_make_pcpu_route() calls ip6_rt_pcpu_alloc(rt) which then
calls dst_alloc(). dst_alloc() _may_ call ip6_dst_gc() which takes
the write_lock(&tabl->tb6_lock). A visualized version:
read_lock(&table->tb6_lock);
rt6_make_pcpu_route();
=> ip6_rt_pcpu_alloc();
=> dst_alloc();
=> ip6_dst_gc();
=> write_lock(&table->tb6_lock); /* oops */
The fix is to do a read_unlock first before calling ip6_rt_pcpu_alloc().

* Due to HW bug, LAN8700 sometimes does not detect presence of energy in the
Ethernet cable in Energy Detect Power-Down mode (e.g while EDPWRDOWN bit is
set, the ENERGYON bit does not asserted sometimes). This is a common bug of
LAN87xx family of PHY chips.
* The lan87xx_read_status() was improved to acquire ENERGYON bit. Its previous
algorythm still not reliable on 100 % and sometimes skip cable plugging.

Pagetables can be moved and therefore the page directory update can be necessary
for the current cs even if none of the the bo's are moved. In that scenario
there is no fence between the sdma0 and gfx ring, so we add one.
