4a4555a7f1 drm/nouveau/volt: Parse the max voltage map entries
There are at least three "max" entries, which specify the max voltage.
Because they are actually normal voltage map entries, they can also be
affected by the temperature.

Nvidia respects those entries and if they get changed, nvidia uses the
lower voltage from all three.

We shouldn't exceed those voltages at any given time.

v2: State what those entries do in the source.
v3: Add the third max entry.
v5: Better describe the entries.

17d063dbdc drm/nouveau/clk: Don't create cstates with voltages higher than what the gpu can do
nvkm_volt_map_min is a copy of nvkm_volt_map, which always returns the
lowest possible voltage for a cstate.

nvkm_volt_map will get a temperature parameter there later and also fix
the voltage calculation, so that this functions will be completly
different later.

32dd7f2329 drm/nouveau/bios/volt: Handle voltage table version 0x50 with zeroed header
Some Fermi+ GPUs specify VID information via voltage table entries, rather
than describing them as a range in the header.

The mask may be bigger than 0x1fffff, but this value is already >2V, so it
will be fine for now.

This patch fixes volting issues on those cards enabling them to switch
cstates.

a8c119a4d0 drm/nouveau/iccsense: Parse the resistors and config the right way
Previously we parsed that table a bit wrong:
1. The entry layout depends on the sensor type used.
2. We have all resitors in one entry for the INA3221.
3. The config is already included in the vbios.

This commit addresses that issue and with that we should be able to read
out the right power consumption for every GPU with a INA209, INA219 and
INA3221.

00085f1efa dma-mapping: use unsigned long for dma_attrs
The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer.  Thus the pointer can point to const data.
However the attributes do not have to be a bitfield.  Instead unsigned
long will do fine:

1. This is just simpler.  Both in terms of reading the code and setting
   attributes.  Instead of initializing local attributes on the stack
   and passing pointer to it to dma_set_attr(), just set the bits.

2. It brings safeness and checking for const correctness because the
   attributes are passed by value.

We default to 128KiB pages (With per-instance for GM200, but the current

20560a9a3c drm/nouveau/secboot: lazy-load firmware and be more resilient
Defer the loading of firmware files to the chip-specific part of secure
boot. This allows implementations to retry loading firmware if the first
attempt failed ; for the GM200 implementation, this happens when trying
to reset a falcon, typically in reaction to GR init.

Firmware loading may fail for a variety of reasons, such as the
filesystem where they reside not being ready at init time. This new
behavior allows GR to be initialized the next time we try to use it if
the firmware has become available.

22b6c9e8fe drm/nouveau/clk/gm20b: add glitchless and DFS support
This patch adds support for advanced features supported by the
Noise-Aware PLL of Maxwell. Glitchless switch allows the PL field to be
updated without disabling the PLL first if the SYNC_MODE bit of the CFG
register is set.

More significantly, DFS allows the PLL to monitor the actual input
voltage and to dynamically lower the output frequency accordingly. This
allows the clock to be more tolerant of lower voltages.

These improvements are only supported for Tegra speedos >= 1.

Also add the voltage table that is suitable for GM20B's NAPLL. This
change needs to be done atomically for the right voltages to be used by
the clock driver.

v2. Fix build on non-Tegra platforms

As it turns out, a value of 0xff means "any protocol" and not "VGA".

c6007dc4e5 drm/nouveau/devinit/gf100: make devinit on resume safer
In case of successful suspend, devinit will have to be run and this is
the behavior currently hardcoded. However, as FD bug 94725 suggests,
there might be cases where runtime suspend leaves the GPU powered, and
in such cases devinit should not be run on resume.

On GF100+ we have a reliable way to know whether we need to run devinit.
Use it instead of blindly trusting the flag set by nvkm_devinit_fini().

The code around the NvForcePost also needs to be slightly reworked in
order to keep working.
