Since the dirtyfb ioctl doesn't give us any hints as to which plane is
scanning out the fb it's marking as damaged, we need to loop through
planes to find it.
Currently we just reach into plane state and check, but that can race
with another commit changing the fb out from under us. This patch locks
the plane before checking the fb and will release the lock if the plane
is not displaying the dirty fb.

The LCD timing definitions between Linux DRM vs Allwinner are different,
below diagram shows this clear differences.
Active Front Sync Back
Region Porch Porch
<-----------------------><----------------><--------------><-------------->
//////////////////////|
////////////////////// |
////////////////////// |.................. ................
________________
<----- [hv]display ----->
<------------- [hv]sync_start ------------>

<-------------------------------- [hv]total ------------------------------>
<----- lcd_[xy] --------> <- lcd_[hv]spw ->
<---------- lcd_[hv]bp --------->
<-------------------------------- lcd_[hv]t ------------------------------>
The DSI driver misinterpreted the vbp term from the BSP code to refer
only to the backporch, when in fact it was backporch + sync. Thus the
driver incorrectly used the vertical front porch plus sync in its
calculation of the DRQ set bit value, when it should not have included
the sync timing.
Including additional sync timings leads to flip_done timed out as:

The static structure tilcdc_plane_funcs, of type drm_plane_funcs, is
used only when passed the fourth argument to drm_plane_init(); however,
this fourth parameter is declared as const in the function definition.
Hence make tilcdc_plane_funcs constant as well.

The DDC/CI protocol involves sending a multi-byte request to the
display via I2C, which is typically followed by a multi-byte
response. The internal I2C controller only allows single byte
reads/writes or reads of 8 sequential bytes, hence DDC/CI is not
supported when the internal I2C controller is used. The I2C
transfers complete without errors, however the data in the response
is garbage. Abort transfers to/from slave address 0x37 (DDC) with
-EOPNOTSUPP, to make it evident that the communication is failing.

It is possible for one HDMI connector to have multiple CEC adapters. The
typical real-world scenario is that where one adapter is used when the
device is in standby, and one that's better/smarter when the device is
powered up.
The cec-notifier changes were made with that in mind, but I missed that in
order to support this you need to tell cec_notifier_cec_adap_unregister()
which adapter you are unregistering from the notifier.
Add this additional argument. It is currently unused, but once all drivers
use this, the CEC core will be adapted for these use-cases.

Pair the gmbus setup and teardown in the same layer. This also fixes the
double gmbus teardown on the i915_driver_modeset_probe() error path.
Move the gmbus setup a bit later in the sequence to make the follow-up
refactoring easier, and to pinpoint any unexpected consequences of this
change right here, instead of the later refactoring.

Split out code related to vga switcheroo register/unregister and state
handling from i915_drv.c into new i915_switcheroo.[ch] files.
It's a bit difficult to draw the line how much to move to the new file
from i915_drv.c, but it seemed to me keeping i915_suspend_switcheroo()
and i915_resume_switcheroo() in place was the cleanest.

Read the PHY-specific status register for the current operating mode
(speed and duplex) of the PHY. This register reflects the actual
mode that the PHY has resolved depending on either the advertisements
of autoneg is enabled, or the forced mode if autoneg is disabled.
This ensures that phylib's software state always tracks the hardware
state.
It seems both AR8033 (which uses the AR8031 ID) and AR8035 support
this status register. AR8030 is not known at the present time.
This patch depends on "net: phy: extract pause mode" and "net: phy:
extract link partner advertisement reading".

When userspace writes to the MII_ADVERTISE register, we update phylib's
advertising mask and trigger a renegotiation. However, writing to the
MII_CTRL1000 register, which contains the gigabit advertisement, does
neither. This can lead to phylib's copy of the advertisement becoming
de-synced with the values in the PHY register set, which can result in
incorrect negotiation resolution.

mdio_device_reset() makes use of the atomic-pretending API flavor for
handling the PHY reset GPIO line.
I found no hint that mdio_device_reset() is called from atomic context
and indeed it uses usleep_range() since long time, so I would assume that
it is OK to sleep there.
This patch switch to gpiod_set_value_cansleep() in mdio_device_reset().
This is relevant if e.g. the PHY reset line is tied to a I2C GPIO
controller.
This has been tested on a ZynqMP board running an upstream 4.19 kernel and
then hand-ported on current kernel tree.

r8152 may fail to establish network connection after resume from system
suspend.
If the USB port connects to r8152 lost its power during system suspend,
the MAC address was written before is lost. The reason is that The MAC
address doesn't get written again in its reset_resume callback.
So let's set MAC address again in reset_resume callback. Also remove
unnecessary lock as no other locking attempt will happen during

The current "disable C3+" workaround for the delayed vblank
irqs on i945gm no longer works. I'm not sure what changed, but
now I need to also disable C2. I also got my hands on a i915gm
machine that suffers from the same issue.
After some furious poking of registers I managed to find a
better workaround: The "Do not Turn off Core Render Clock in C
states" bit. With that I no longer have to disable any C-states,
and as a nice bonus the power cost is only ~1/4 of the
"disable C3+" method (which mind you doesn't even work anymore,
and so would have an even higher power cost if we made it work
by also disabling C2).
So let's throw out all the cpuidle/qos crap and just toggle
the magic bit as needed. And we extend the workaround to cover
i915gm as well.

With the introduction of ctx->engines[] we allow multiple logical
contexts to be used on the same engine (e.g. with virtual engines).
According to bspec, aach logical context requires a unique tag in order
for context-switching to occur correctly between them. [Simple
experiments show that it is not so easy to trick the HW into performing
a lite-restore with matching logical IDs, though my memory from early
Broadwell experiments do suggest that it should be generating
lite-restores.]
We only need to keep a unique tag for the active lifetime of the
context, and for as long as we need to identify that context. The HW
uses the tag to determine if it should use a lite-restore (why not the
LRCA?) and passes the tag back for various status identifies. The only
status we need to track is for OA, so when using perf, we assign the
specific context a unique tag.
v2: Calculate required number of tags to fill ELSP.

As our global unpark/park keep track of the number of active users, we
can simply move the accounting from the GEM layer to the base GT layer.
It was placed originally inside GEM to benefit from the 100ms extra
delay on idleness, but that has been eliminated and now there is no
substantive difference between the layers. In moving it, we move another
piece of the puzzle out from underneath struct_mutex.

Now that we can retire without taking struct_mutex, we can do so to
handle shrinking the mmap-offset space after an allocation failure.

wait_for_timelines is essentially the same loop as retiring requests
(with an extra timeout), so merge the two into one routine.
v2: i915_retire_requests_timeout and keep VT'd w/a as !interruptible

We don't need to hold struct_mutex now for retiring requests, so drop it
from i915_retire_requests() and i915_gem_wait_for_idle(), finally
removing I915_WAIT_LOCKED for good.
