The locking of release_lock was stupid; t should have been be called with
fence_lock_irq if it was legitimately used. Unfortunately it never protected
anything except the fence implementation correctly.

The PHY configuration is stored in an opaque "config" field, but when
allocating the structure, its proper size needs to be known. In the case
of UTMI, the proper structure is tegra_utmip_config of which a local
variable already exists, so we can use that to obtain the size from.
Fixes the following warning from the sparse checker:
drivers/usb/phy/phy-tegra-usb.c:882:17: warning: expression using sizeof(void)
Fixes: 81d5dfe6d8b3 (usb: phy: tegra: Read UTMIP parameters from device tree)

Up to now, when endpoint addresses in descriptors were non-consecutive,
there were created redundant files, which could cause problems in kernel,
when user tried to read/write to them. It was result of fact that maximum
endpoint address was taken as total number of endpoints in function.
This patch adds endpoint descriptors counting and storing their addresses
in eps_addrmap to verify their cohesion in each speed.
Endpoint address map would be also useful for further features, just like
vitual endpoint address mapping.

This patch fixes the usb_pkt_pop(). If a gadget driver calls
usb_ep_dequeue(), this driver will call the usb_pkt_pop().

This patch fixes the condition of is_done in usbhsf_dma_push_done().
This function will be called after a transmission finished by DMAC.
So, the function should check if the transmission packet is short packet
or not. Also the function should call try_run to send the zero packet
by the pio handler if the "*is_done" is not set. Otherwize, the
transaction will not finish if a gadget driver sets the "zero" flag
in a transmission.

This patch protects the mod->irq_bempsts and mod->irq_brdysts by
spin lock in the usbhs_status_get_each_irq() because other functions
will write them during spin lock. Otherwise, the driver will clears
the BRDYSTS and/or BEMPSTS wrongly, and then, the transaction will not
finish.
Also since the driver should use the INTSTS0 and BRDYSTS and BEMPSTS
as the same timing, the patch protects them.

Some gadget drivers will call usb_ep_queue() more than once before
the first queue doesn't finish. However, this driver didn't handle
it correctly. So, this patch fixes the behavior of some
usbhs_pkt_handle using the "running" flag. Otherwise, the oops below
happens if we use g_ncm driver and when the "iperf -u -c host -b 200M"

- transfer size is multiple of EP packet size,
- and URB_ZERO_PACKET is set in urb->transfer_flags.

IS_GEN8() is a bad check in the forcewake code due to bdw vs. chv
differences. Use IS_BROADWELL() instead.
The only actual bug here is that we currently call
__gen7_gt_force_wake_mt_reset() on chv. On the other places we
have checked for chv before using IS_GEN8(), but change them
to use IS_BROADWELL() anyway to reduce the chance of accidents in the

Also, add a ',' at the end of the last entry. This is to ease the

No point in calling intel_plane_restore() in .set_property() if the
value didn't change.
More importantly this papers over a bug where the current primary plane
code forgets to update the user coordinates we store under intel_plane
unless the primary plane .update_plane() hook is actually called. This
means we have 0 in the coordinates straight after boot and any call
to intel_restore_plane() (such as from restore_fbdev_mode()) will
actually turn off the primary plane. This mess needs to be fixed properly
but that's a bigger task and the first step there is killing off
intel_pipe_set_base() and just calling the primary plane
.update_plane() hook. For the immediate problem of black screen after
boot this small patch is enough to hide it.
The problem originates from these two commits:

830M has problems when some of the pipes are disabled. Namely if a
plane, DVO port etc. is currently assigned to a disabled pipe, it
can't moved to the other pipe until the current pipe is also enabled.
To keep things simple just leave both pipes running all the time.
Ideally I think should turn the pipes off if neither is active, and
when either becomes active we enable both. But that would reuquire
proper atomic modeset support, and probably a bit of extra care in
the order things get enabled.

830 really does want the pipe A quirk. The planes and ports don't
react to any register writes unless the pipe currently attached
to them is running, so it's impossible to move them to the other
pipe unless both pipes are running.
Also it's documented that the DPLL must be enabled on both pipes
whenever it's needed.

The vbt on my Fujitsu-Siemens Lifebook S6010 provides two 800x600 modes,
60Hz and 56Hz. The magic register values we have correspond to the 60Hz
mode, and as I don't know how one would trick the VGA BIOS to set up
the 56Hz mode we can't get the magic values for the orther mode. So
when checking whether a mode is valid also check the pixel clock so that
we filter out the 56Hz variant.

In my earlier rewrite I missed a few important registers. Thomas Richter
noticed that they're needed to make his machine resume correctly.
Looks like IEGD does a one time init of these three registers. We don't
have a good one time init place in the ns2501 driver, so let's just
stick them into the .mode_set() hook and see if that helps things along.

Try to use the same programming sequence as used by the IEGD driver.
Also shovel the magic register values into a big static const array.
The register values are actually the based on what the BIOS programs
on the Fujitsu-Siemens Lifebook S6010. IEGD seemed to have hardcoded
register values (which also enabled the scaler for 1024x768 mode).
However those didn't actually work so well on the S6010. Possibly the
pipe timings that got used didn't match the ns2501 configuration.
