The method struct drm_connector_helper_funcs::mode_valid is defined
as returning an 'enum drm_mode_status' but the driver implementation
for this method uses an 'int' for it.
Fix this by using 'enum drm_mode_status' in the driver too.

If the initial fbdev configuration (intel_fbdev_initial_config()) runs
and there still no sink connected it will cause
drm_fb_helper_initial_config() to return 0 as no error happened (but
internally the return is -EAGAIN). Because no framebuffer was
allocated, when a sink is connected intel_fbdev_output_poll_changed()
will not execute drm_fb_helper_hotplug_event() that would trigger
another try to do the initial fbdev configuration.
So here allowing drm_fb_helper_hotplug_event() to be executed when there
is no framebuffer allocated and fbdev was not set up yet.
This issue also happens when a MST DP sink is connected since boot, as
the MST topology is discovered in parallel if
intel_fbdev_initial_config() is executed before the first sink MST is
discovered it will cause this same issue.
This is a follow-up patch of
https://patchwork.freedesktop.org/patch/196089/
Changes from v1:
- not creating a dump framebuffer anymore, instead just allowing
drm_fb_helper_hotplug_event() to execute when fbdev is not setup yet.

We use jiffies to determine when wait expires. However
Imre did find out that jiffies can and will do a >1
increments on certain situations [1]. When this happens
in a wait_for loop, we return timeout errorneously
much earlier than what the real wallclock would say.
We can't afford our waits to timeout prematurely.
Discard jiffies and change to ktime to detect timeouts.

The OPAL RTC driver does not sleep in case it gets OPAL_BUSY or
OPAL_BUSY_EVENT from firmware, which causes large scheduling
latencies, up to 50 seconds have been observed here when RTC stops

Fix this by converting it to the standard form OPAL_BUSY loop that

Otherwise, the SQ may skip some of the register writes, or shader waves may
be allocated where we don't expect them, so that as a result we don't actually

Commit 5928c281524f (ACPI / video: Default lcd_only to true on Win8-ready
and newer machines) made only_lcd default to true on all machines where
acpi_osi_is_win8() returns true, including laptops.
The purpose of this is to avoid the bogus / non-working acpi backlight
interface which many newer BIOS-es define on desktop machines.
But this is causing a regression on some laptops, specifically on the
Dell XPS 13 2013 model, which does not have the LCD flag set for its
fully functional ACPI backlight interface.
Rather then DMI quirking our way out of this, this commits changes the
logic for setting only_lcd to true, to only do this on machines with
a desktop (or server) dmi chassis-type.
Note that we cannot simply only check the chassis-type and not register
the backlight interface based on that as there are some laptops and
tablets which have their chassis-type set to "3" aka desktop. Hopefully
the combination of checking the LCD flag, but only on devices with
a desktop(ish) chassis-type will avoid the needs for DMI quirks for this,
or at least limit the amount of DMI quirks which we need to a minimum.

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates 2018-04-24
This series contains fixes to ixgbevf, igb and ice drivers.
Colin Ian King fixes the return value on error for the new XDP support
that went into ixgbevf for 4.17.
Vinicius provides a fix for queue 0 for igb, which was not receiving all
the credits it needed when QAV mode was enabled.
Anirudh provides several fixes for the new ice driver, starting with
properly initializing num_nodes_added to zero. Fixed up a code comment
to better reflect what is really going on in the code. Fixed how to
detect if an OICR interrupt has occurred to a more reliable method.
Md Fahad fixes the ice driver to allocate the right amount of memory
when reading and storing the devices MAC addresses. The device can have
up to 2 MAC addresses (LAN and WoL), while WoL is currently not
supported, we need to ensure it can be properly handled when support is
added.

For the MAC read operation, the device can return up to two (LAN and WoL)
MAC addresses. Without access to adequate memory, the device will return
an error. Fixed this by allocating the right amount of memory. Also, logic
to detect and copy the LAN MAC address into the port_info structure has
been added. Note that the WoL MAC address is ignored currently as the WoL
feature isn't supported yet.

According to the hardware spec, checking the INTEVENT bit isn't a
reliable way to detect if an OICR interrupt has occurred. This is
because this bit can be cleared by the hardware/firmware before the
interrupt service routine has run. So instead, just check for OICR
events every time.

When Qav mode is enabled, queue 0 should be kept on Stream Reservation
mode. From the i210 datasheet, section 8.12.19:
"Note: Queue0 QueueMode must be set to 1b when TransmitMode is set to
Qav." ("QueueMode 1b" represents the Stream Reservation mode)
The solution is to give queue 0 the all the credits it might need, so
it has priority over queue 1.
A situation where this can happen is when cbs is "installed" only on
queue 1, leaving queue 0 alone. For example:
$ tc qdisc replace dev enp2s0 handle 100: parent root mqprio num_tc 3 \
map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 queues 1@0 1@1 2@2 hw 0

Note that a pile of drivers don't seem to take implicit fencing into
account, or at least don't call drm_atoimc_set_fence_for_plane().
Cc'ing relevant people, or at least some. Some drivers also look like
they don't disable implicit fencing (e.g. amdgpu) because the explicit
fences and implicit fences are handled by entirely independent code
paths.
I also wonder whether we shouldn't just make the recommended helpers
the default ones, since a lot of drivers don't bother to handle the
implicit fences at all it seems. The helpers won't blow up even for
non-GEM drivers or GEM drivers which don't fill out the gem bo
pointers in struct drm_framebuffer.

There's nothing tinydrm specific to this, and there's a few more
copies of the same in various other drivers.

The Lenovo Ideapad Mixx 320 laptop uses a portrait LCD panel, add a
quirk for this.
While at it instead of duplicating the same drm_dmi_panel_orientation_data
for 3 laptops add a generic lcd800x1280_rightside_up orientation_data and
use that for all 3 (including the new Mixx 320 entry).

Modules such as nouveau.ko and i915.ko have a link time dependency on
acpi_lid_open(), and due to its use of acpi_bus_register_driver(),
the button.ko module that provides it is only loadable when booted in
ACPI mode. However, the ACPI button driver can be built into the core
kernel as well, in which case the dependency can always be satisfied,
and the dependent modules can be loaded regardless of whether the
system was booted in ACPI mode or not.
So let's fix this asymmetry by making the ACPI button driver loadable
as a module even if not booted in ACPI mode, so it can provide the
acpi_lid_open() symbol in the same way as when built into the kernel.

Currently if a user requests clock counters for a node without a GPU
resource we will always return EINVAL.
Instead if no GPU resource is attached, fill the gpu_clock_counter
argument with zeroes so that we may proceed and return valid CPU
counters.

Passing NULL pointer to PTR_ERR will result in return value of 0
indicating success which is clearly not what it is intended here.
This patch returns -EINVAL instead.

WDAT table on Lenovo Z50-70 is using RTC SRAM (ports 0x70 and 0x71) to
store state of the timer. This conflicts with Linux RTC driver
(rtc-cmos.c) who fails to reserve those ports for itself preventing RTC
from functioning. In addition the WDAT table seems not to be fully
functional because it does not reset the system when the watchdog times
out.
On this system iTCO_wdt works just fine so we simply prefer to use it
instead of WDAT. This makes RTC working again and also results working
watchdog via iTCO_wdt.
