According to the datasheet of the panel, both data, DEN and sync signals
are expected to be driven on the falling edge of the DOTCLK.

omap_video_timings can be replaced with the generic videomode in omapdrm
and the omap_video_timings can be removed.
This patch will replace the omap_video_timings with videomode.
With the change we no longer need the functions to convert to/from
videomode and drm_display_mode to omap_video_timings, these can be removed
as well.

omap_video_timings struct have the same members as struct videomode, but
their types are different. As first step change the types of the
omap_video_timings struct members to match their counterpart in
struct videomode to catch any type cast related issues.

There are display panels which demands that the sync signal is driven on
different edge than the pixel data.
With the syncclk-active property we can specify the clk edge to be used to
drive the sync signal. When the property is missing it indicates that the
sync is driven on the same edge as the pixel data.

omap_plane_atomic_update() does WARN_ON() if dispc rejects the given
plane config. Change that to dev_err() to lessen the possible spam.
To fix this correctly, the plane setup needs much more work by creating
a check function for dispc setup, so that we could reliably check the
config in atomic_check, instead of only noticing the problem when
programming dispc.

I sometimes see:
[drm:drm_framebuffer_remove [drm]] *ERROR* failed to reset crtc ed2a6c00
when fb was deleted: -22
which comes from drm_framebuffer_remove() when it's disabling the crtc
with zeroed drm_mode_set.
The problem in omap_plane_atomic_check() is that it will use those
zeroed fields to verify if the setup is correct.
This patch makes omap_plane_atomic_check() return 0 if the crtc is
disabled.

This fixes the irq allocation in this driver to not print:
irq: Cannot allocate irq_descs @ IRQ34, assuming pre-allocated
irq: Cannot allocate irq_descs @ IRQ66, assuming pre-allocated
Which happens because the driver already called irq_alloc_descs()
and so the change to use irq_domain_add_simple resulted in calling
irq_alloc_descs() twice.
Modernize the irq allocation in this driver to use the
irq_domain_add_linear flow directly and eliminate the use of

Check whether the kernel really supports power resources for a device,
otherwise the power might not be removed when the device is runtime
suspended (DSM should still work in these cases where PR does not).
This is a workaround for a problem where ACPICA and Windows 10 differ in
behavior. ACPICA does not correctly enumerate power resources within a
conditional block (due to delayed execution of such blocks) and as a
result power_resources is set to false even if _PR3 exists.

Sylvain Lemieux reports the LPC32xx GPIO driver is broken since
commit 762c2e46c059 ("gpio: of: remove of_gpiochip_and_xlate() and
struct gg_data"). Probably, gpio-etraxfs.c and gpio-davinci.c are
broken too.
Those drivers register multiple gpio_chip that are associated to a
single OF node, and their own .of_xlate() checks if the passed
gpio_chip is valid.
Now, the problem is of_find_gpiochip_by_node() returns the first
gpio_chip found to match the given node. So, .of_xlate() fails,
except for the first GPIO bank.
Reverting the commit could be a solution, but I do not want to go
back to the mess of struct gg_data. Another solution here is to
take the match by a node pointer and the success of .of_xlate().
It is a bit clumsy to call .of_xlate twice; for gpio_chip matching
and for really getting the gpio_desc index. Perhaps, our long-term
goal might be to convert the drivers to single chip registration,
but this commit will solve the problem until then.

When allocating a new line handle or event a file is allocated that it is
associated to. The file is attached to a file descriptor of the current
process and the file descriptor is returned to userspace using
copy_to_user(). If this copy operation fails the line handle or event
allocation is aborted, all acquired resources are freed and an error is
returned.
But the file struct is not freed and left attached to the userspace
application and even though the file descriptor number was not copied it is
trivial to guess. If a userspace application performs a IOCTL on such a
left over file descriptor it will trigger a use-after-free and if the file
descriptor is closed (latest when the application exits) a double-free is
triggered.
anon_inode_getfd() performs 3 tasks, allocate a file struct, allocate a
file descriptor for the current process and install the file struct in the
file descriptor. As soon as the file struct is installed in the file
descriptor it is accessible by userspace (even if the IOCTL itself hasn't
completed yet), this means uninstalling the fd on the error path is not an
option, since userspace might already got a reference to the file.
Instead anon_inode_getfd() needs to be broken into its individual steps.
The allocation of the file struct and file descriptor is done first, then
the copy_to_user() is executed and only if it succeeds the file is
installed.
Since the file struct is reference counted it can not be just freed, but
its reference needs to be dropped, which will also call the release()
callback, which will free the state attached to the file. So in this case
the normal error cleanup path should not be taken.

Pull spi fixes from Mark Brown: "A few small fixes for SPI, one core fix
that only applies in cases where we're handling DT overlays and a
couple of driver specific fixes:
- Fix handling of error cases when instantiating DT overlays so we
don't end up just ignoring devices that encountered an error during
instantiation.
- Avoid reading uninitialized data when handing spurious interrupts
in the espi driver.
- A driver specific fix for the dspi driver to fix a bad interaction
with u-boot"

spi: mark device nodes only in case of successful instantiation

The stack frame size could grow too large when the plugin used long long
on 32-bit architectures when the given function had too many basic blocks.
The gcc warning was:
drivers/pci/hotplug/ibmphp_ebda.c: In function 'ibmphp_access_ebda':
drivers/pci/hotplug/ibmphp_ebda.c:409:1: warning: the frame size of 1108 bytes is larger than 1024 bytes [-Wframe-larger-than=]
This switches latent_entropy from u64 to unsigned long.
Thanks to PaX Team and Emese Revfy for the patch.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator fix from Mark Brown:
"Fix ramp_delay warnings for v4.9
A new warning was introduced for missing information about the time
that regulators take to power on in v4.9. This is in theory a real
issue but for most practical regulators the communication overhead of
talking to the device is greater than the ramp time so a lot of
drivers don't set it and the warning is far too noisy without
identifying practical issues.
Just remove the warning for now"

Pull regmap fixes from Mark Brown:
"A couple of small build fixes here, nothing major.
The missing include is triggered in some configurations and the
renaming of ret is defensive for the benefit of some drivers people
are in the process of mainlining"
