Currently we're doing the reset handling a bit late, and we're doing
it both in the driver load code and on resume. This makes it unusable
for e.g. resetting the panel power sequence state like Paulo wants to.
Instead of adding yet another single-use callback shuffle things
around:
- Output handling code is responsible to reset/init all state on its
own at driver load time.
- We call the reset functions much earlier, before we start using any
of the modeset code.
Compared to Paulo's new ->resume callback the only difference in
placement is that ->reset is still called without dev->struct_mutex
held. Which is imo a feature.

Because we already do the wait in software: see

For the "backlight on" delay, even BSpec says we need to program 0x1
to PP_ON_DELAYS 12:0.
For the "backlight off" delay, if we don't do the same thing, when we
call ironlake_wait_panel_off we'll end up waiting for the it again.
On my machine the off delay is 200ms, so we save this amount of time
whenever we disable the panel (e.g, suspend).

Function ironlake_wait_panel_off should just wait for the power off
delay, while function ironlake_wait_panel_power_cycle should wait for
the panel cycle (that's required after we turn the panel off, before
we enable it again).
The problem is that, currently, ironlake_wait_panel_off is waiting not
just for the panel to be off, but also for the power cycle delay and
the backlight off delay. This function relies on the PP_STATUS bits
3:0, which are not documented and not supposed to be used. A quick
analysis of the values we get while waiting quickly shows that power
off is reached while bits 3:0 are still 0x1, and the time it takes to
become 0x0 is the power cycle delay.
On my system with backlight off delay of 200ms, power down delay of
50ms and power cycle delay of 500ms, this is what I get:
- Start waiting with value 0x80000008, timestamp 6.429364.
- Jumps to 0xa0000003, timestamp 6.431360 (time waited: 0.001996)
- Jumps to 0xa0000002, timestamp 6.631277 (time waited: 0.201913)
- Jumps to 0x08000001, timestamp 6.681258 (time waited: 0.251894)
- Jumps to 0x00000000, timestamp 7.192012 (time waited: 0.762648)
As you can see, ironlake_wait_panel_off is sleeping 760ms instead of
the expected 50ms: the first 200ms matches the backlight off delay
(which we should already have waited for!), then the 50ms for the real
panel off delay, then the 500ms for the panel power cycle.
This patch makes is look just at bits 31 and 29:28, which will ignore
the panel power cycle.
And just to be clear: this saves 500ms on my system every time we
disable the panel. But we can still save 200ms more (the backlight off
delay) on the next patches.

intel_ddi.c, those get an intel_ prefix.
While at it make the vdd_on/off functions static.

The eDP spec defines some points where after you do action A, you have
to wait some time before action B. The thing is that in our driver
action B does not happen exactly after action A, but we still use
msleep() calls directly. What this patch does is that we record the
timestamp of when action A happened, then, just before action B, we
look at how much time has passed and only sleep the remaining amount
needed.
With this change, I am able to save about 5-20ms (out of the total
200ms) of the backlight_off delay and completely skip the 1ms
backlight_on delay. The 600ms vdd_off delay doesn't happen during
normal usage anymore due to a previous patch.
v2: - Rename ironlake_wait_jiffies_delay to intel_wait_until_after and
move it to intel_display.c
- Fix the msleep call: diff is in jiffies
v3: - Use "tmp_jiffies" so we don't need to worry about the value of
"jiffies" advancing while we're doing the math.
v4: - Rename function again.
- Move function to i915_drv.h.
- Store last_power_cycle at edp_panel_off too.
- Use msecs_to_jiffies_timeout, then replace the msleep with an
open-coded version that avoids the extra +1 jiffy.
- Try to add units to every variable name so we don't confuse
jiffies with milliseconds.

Our driver has two different ways of waiting for panel power
sequencing delays. One of these ways is through
ironlake_wait_panel_status, which implicitly uses the values written
to our registers. The other way is through the functions that call
intel_wait_until_after, and on this case we do direct msleep() calls
on the intel_dp->xxx_delay variables.
Function intel_dp_init_panel_power_sequencer is responsible for
initializing the _delay variables and deciding which values we need to
write to the registers, but it does not write these values to the
registers. Only at intel_dp_init_panel_power_sequencer_registers we
actually do this write.
Then problem is that when we call intel_dp_i2c_init, we will get some
I2C calls, which will trigger a VDD enable, which will make use of the
panel power sequencing registers and the _delay variables, so we need
to have both ready by this time. Today, when this happens, the _delay
variables are zero (because they were not computed) and the panel
power sequence registers contain whatever values were written by the
BIOS (which are usually correct).
What this patch does is to make sure that function
intel_dp_init_panel_power_sequencer is called earlier, so by the time
we call intel_dp_i2c_init, the _delay variables will already be
initialized. The actual registers won't contain their final values,
but at least they will contain the values set by the BIOS.
The good side is that we were reading the values, but were not using
them for anything (because we were just skipping the msleep(0) calls),
so this "fix" shouldn't fix any real existing bugs. I was only able to
identify the problem because I added some debug code to check how much
time time we were saving with my previous patch.

This reverts commit 446f254566.
I've left the masking in the pageflip code since that seems to be some
useful piece of preemptive robustness.
Iirc I've merged this patch under the assumption that the BIOS leaves
some random gunk in the lower bits and gets unhappy if we trample on
them. We have quite a few case like this, so this made sense.
Now I've just learned that there's actual hardware features bits in
the low 12 bits, and the kernel needs to preserve them to allow a
userspace blob to do its job. Given Dave Airlie's clear stance on
userspace blob drivers I've quickly chatted with him and he doesn't
seem too happy. So let's revert this.
If there are indeed bits that we must preserve in this range then we
can ressurrect this patch, but with proper documentation for those
bits supplied. And we probably also need to think a bit about
interactions with our driver.

CPUs on cold boot, so that, even if the register used to store the percpu

Merge tag 'clk-for-linus-3.14-part1' of git://git.linaro.org/people/mike.turquette/linux
Pull clk framework changes from Mike Turquette:
"The first half of the clk framework pull request is made up almost
entirely of new platform/driver support. There are some conversions
of existing drivers to the common-clock Device Tree binding, and a few
non-critical fixes to the framework.
Due to an entirely unnecessary cyclical dependency with the arm-soc
tree this pull request is broken into two pieces. The second piece
will be sent out after arm-soc sends you the pull request that merged
in core support for the HiSilicon 3620 platform. That same pull
request from arm-soc depends on this pull request to merge in those
HiSilicon bits without causing build failures"
[ Just did the ARM SoC merges, so getting ready for the second clk tree

Updates of SoC-near drivers and other driver updates that makes more sense to
take through our tree.
The largest part of this is a conversion of device registration for some
renesas shmobile/sh devices over to use resources. This has required
coordination with the corresponding arch/sh changes, and we've agreed
to merge the arch/sh changes through our tree.
Added in this branch is support for Trusted Foundations secure firmware,
which is what is used on many of the commercial Nvidia Tegra products
that are in the market, including the Nvidia Shield. The code is local
to arch/arm at this time since it's uncertain whether it will be shared
with arm64 longer-term, if needed we will refactor later.
A couple of new RTC drivers used on ARM boards, merged through our tree
on request by the RTC maintainer.
... plus a bunch of smaller updates across the board, gpio conversions
for davinci, etc.

DT and DT-conversion-related changes for various ARM platforms. Most
of these are to enable various devices on various boards, etc, and not
necessarily worth enumerating.
New boards and systems continue to come in as new devicetree files that
don't require corresponding C changes any more, which is indicating that
the system is starting to work fairly well.
A few things worth pointing out:
* ST Ericsson ux500 platforms have made the major push to move over to fully
support the platform with DT.
* Renesas platforms continue their conversion over from legacy platform devices
to DT-based for hardware description.
