Make resume/on codepath not to wait for panel_power_cycle_delay(t11_t12)
if this time is already spent in suspend/poweron time.
v2: Use CLOCK_BOOTTIME and remove jiffies for panel power cycle
delay calculation(Ville).
v3: Addressed below comments
1. Tracking time from where last powercycle is initiated.
2. Used ktime_get_bootime() wrapper for boottime clock.
3. Used ktime_ms_delta() to get time difference.
v4: Updated v3 change log in detail.
v5: Removed static from panel_power_on_time(Stéphane).

The userspace might need some sort of cache coherency management e.g. when CPU
and GPU domains are being accessed through dma-buf at the same time. To
circumvent this problem there are begin/end coherency markers, that forward
directly to existing dma-buf device drivers vfunc hooks. Userspace can make use
of those markers through the DMA_BUF_IOCTL_SYNC ioctl. The sequence would be
used like following:
- mmap dma-buf fd
- for each drawing/upload cycle in CPU 1. SYNC_START ioctl, 2. read/write
to mmap area 3. SYNC_END ioctl. This can be repeated as often as you
want (with the new data being consumed by the GPU or say scanout device)
- munmap once you don't need the buffer any more
v2 (Tiago): Fix header file type names (u64 -> __u64)
v3 (Tiago): Add documentation. Use enum dma_buf_sync_flags to the begin/end
dma-buf functions. Check for overflows in start/length.
v4 (Tiago): use 2d regions for sync.
v5 (Tiago): forget about 2d regions (v4); use _IOW in DMA_BUF_IOCTL_SYNC and
remove range information from struct dma_buf_sync.
v6 (Tiago): use __u64 structured padded flags instead enum. Adjust
documentation about the recommendation on using sync ioctls.
v7 (Tiago): Alex' nit on flags definition and being even more wording in the
doc about sync usage.
v9 (Tiago): remove useless is_dma_buf_file check. Fix sync.flags conditionals
and its mask order check. Add <linux/types.h> include in dma-buf.h.

Backmerge to get at the new encoder_mask support in atomic helpers.
Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>

This module is heavily based on i2c-dev. Once loaded, it provides one
dev node per DP AUX channel, named drm_dp_auxN, where N is an integer.
It's possible to know which connector owns this aux channel by looking
at the respective sysfs /sys/class/drm_aux_dev/drm_dp_auxN/connector, if
the connector device pointer was correctly set in the aux helper struct.
Two main operations are provided on the registers read and write. The
address of the register to be read or written is given using lseek. The
seek position is updated upon read or write.
v2:
- lseek is used to select the register to read/write
- read/write are used instead of ioctl
- no blocking_notifier is used, just a direct callback
v3:
- use drm_dp_aux_dev prefix for public functions
- chardev is named drm_dp_auxN
- read/write don't allocate a buffer anymore, and transfer up to 16 bytes a
time
- remove notifier list from the implementation
- option on menuconfig is now a boolean
- add inline stub functions to avoid breakage when this option is disabled
v4:
- fix build system changes - actually disable this module when not selected.
v5:
- Use kref to avoid device closing while still in use
- Don't use list, use an idr for storing aux_dev
- Remove "connector" attribute
- set aux.dev to the connector drm_connector device, instead of
drm_device
v6:
- Use atomic_t for usage count
- Use a mutex instead of spinlock for idr lock
- Destroy chardev immediately on unregister
- other minor suggestions from Ville
v7:
- style fixes
- error handling fixes
v8:
- more error handling fixes
v9:
- remove module_init and module_exit, and add drm_dp_aux_dev_init/exit
to drm_kms_helper_init/exit.

The tvp5150 decoder has different input connectors. The actual list of
HW inputs depends on the device version but all have at least these 3:
1) Composite0
2) Composite1
3) S-Video
and some variants have a 4th possible input connector:
4) Signal generator
The driver currently uses the .s_routing callback to switch the input
connector but since these are separate HW blocks, it's better to use
media entities to represent the input connectors and their source pads
linked with the decoder's sink pad.
This allows user-space to use the MEDIA_IOC_SETUP_LINK ioctl to choose
the input connector. For example using the media-ctl user-space tool:
$ media-ctl -r -l '"Composite0":0->"tvp5150 1-005c":0[1]'

The fake agp driver for the intel graphics gart is only needed for ums
support. And we ditched that a long time ago:
commit 03dae59c72ffffd8ef6e005f48ba356c863e0587
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date: Wed Jul 23 16:27:25 2014 +0200
drm/i915: Ditch UMS config option
With this there's no longer the problem that 2 drivers (fake agp
driver and the drm/i915 driver) fight over the same piece, which fixes
apparent dma leaks detected by CONFIG_DMA_API_DEBUG.
Note that the leak isn't real since intel-gtt refcounts and will tear
down eventually. But the debug code assumes that when the i915 driver
unbinds from the pci device everything should be gone. Which isn't the
case if we have intel-agp enabled - userspace might need it. But by
ditching this intel-gtt setup and teardown is completely tied to the
livetime of the "real" driver.
While at it untangle the init ordering a bit - the fake agp wouldn't
be initialized correctly if i915.ko loads first. Which isn't a problem
since when i915 loads in kms mode you won't need the fake agp support
needed by the ums driver ...

While running some tests on the scheduler patches with rpm enabled I
came across a corruption in the ringbuffer, which was root-caused to
the GPU being suspended while commands were being emitted to the
ringbuffer. The access to memory was failing because the GPU needs to
be awake when accessing stolen memory (where my ringbuffer was located).
Since we have this constraint it looks like a sensible idea to check
that we hold a refcount when we access the rungbuffer.
v2: move the check from ring_begin to ringbuffer iomap time (Chris)
v3: update comment (Chris)
