Geert Uytterhoeven b330f3972f fbdev: c2p: Fix link failure on non-inlining
When the compiler decides not to inline the Chunky-to-Planar core
functions, the build fails with:

    c2p_planar.c:(.text+0xd6): undefined reference to `c2p_unsupported'
    c2p_planar.c:(.text+0x1dc): undefined reference to `c2p_unsupported'
    c2p_iplan2.c:(.text+0xc4): undefined reference to `c2p_unsupported'
    c2p_iplan2.c:(.text+0x150): undefined reference to `c2p_unsupported'

Fix this by marking the functions __always_inline.

While this could be triggered before by manually enabling both
CONFIG_OPTIMIZE_INLINING and CONFIG_CC_OPTIMIZE_FOR_SIZE, it was exposed
in the m68k defconfig by commit ac7c3e4ff4 ("compiler: enable
CONFIG_OPTIMIZE_INLINING forcibly").

Fixes: 9012d01166 ("compiler: allow all arches to enable CONFIG_OPTIMIZE_INLINING")

Masahiro Yamada 01bb25156d video/logo: do not generate unneeded logo C files
Currently, all the logo C files are generated irrespective of the
CONFIG options. Adding them to extra-y is wrong. What we need to do
here is to add them to 'targets' so that if_changed works properly.

Files listed in 'targets' are cleaned, so clean-files is unneeded.

Linus Torvalds 5c6bd5de3c Main MIPS changes for v5.4:
- boot_mem_map is removed, providing a nice cleanup made possible by the
   recent removal of bootmem.
 
 - Some fixes to atomics, in general providing compiler barriers for
   smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs or
   MIPS32 systems using cmpxchg64().
 
 - Conversion to the new generic VDSO infrastructure courtesy of Vincenzo
   Frascino.
 
 - Removal of undefined behavior in set_io_port_base(), fixing the
   behavior of some MIPS kernel configurations when built with recent
   clang versions.
 
 - Initial MIPS32 huge page support, functional on at least Ingenic SoCs.
 
 - pte_special() is now supported for some configurations, allowing among
   other things generic fast GUP to be used.
 
 - Miscellaneous fixes & cleanups.
 
 And platform specific changes:
 
 - Major improvements to Ingenic SoC support from Paul Cercueil, mostly
   enabled by the inclusion of the new TCU (timer-counter unit) drivers
   he's spent a very patient year or so working on. Plus some fixes for
   X1000 SoCs from Zhou Yanjie.
 
 - Netgear R6200 v1 systems are now supported by the bcm47xx platform.
 
 - DT updates for BMIPS, Lantiq & Microsemi Ocelot systems.

Linus Torvalds 1f7d290a72 Driver core patches for 5.4-rc1
Here is the big driver core update for 5.4-rc1.
 
 There was a bit of a churn in here, with a number of core and OF
 platform patches being added to the tree, and then after much discussion
 and review and a day-long in-person meeting, they were decided to be
 reverted and a new set of patches is currently being reviewed on the
 mailing list.
 
 Other than that churn, there are two "persistent" branches in here that
 other trees will be pulling in as well during the merge window.  One
 branch to add support for drivers to have the driver core automatically
 add sysfs attribute files when a driver is bound to a device so that the
 driver doesn't have to manually do it (and then clean it up, as it
 always gets it wrong).
 
 There's another branch in here for generic lookup helpers for the driver
 core that lots of busses are starting to use.  That's the majority of
 the non-driver-core changes in this patch series.
 
 There's also some on-going debugfs file creation cleanup that has been
 slowly happening over the past few releases, with the goal to hopefully
 get that done sometime next year.
 
 All of these have been in linux-next for a while now with no reported
 issues.

Linus Torvalds 77dcfe2b9e Power management updates for 5.4-rc1
- Rework the main suspend-to-idle control flow to avoid repeating
    "noirq" device resume and suspend operations in case of spurious
    wakeups from the ACPI EC and decouple the ACPI EC wakeups support
    from the LPS0 _DSM support (Rafael Wysocki).
 
  - Extend the wakeup sources framework to expose wakeup sources as
    device objects in sysfs (Tri Vo, Stephen Boyd).
 
  - Expose system suspend statistics in sysfs (Kalesh Singh).
 
  - Introduce a new haltpoll cpuidle driver and a new matching
    governor for virtualized guests wanting to do guest-side polling
    in the idle loop (Marcelo Tosatti, Joao Martins, Wanpeng Li,
    Stephen Rothwell).
 
  - Fix the menu and teo cpuidle governors to allow the scheduler tick
    to be stopped if PM QoS is used to limit the CPU idle state exit
    latency in some cases (Rafael Wysocki).
 
  - Increase the resolution of the play_idle() argument to microseconds
    for more fine-grained injection of CPU idle cycles (Daniel Lezcano).
 
  - Switch over some users of cpuidle notifiers to the new QoS-based
    frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
    policy notifier events (Viresh Kumar).
 
  - Add new cpufreq driver based on nvmem for sun50i (Yangtao Li).

Pull power management updates from Rafael Wysocki:
 "These include a rework of the main suspend-to-idle code flow (related
  to the handling of spurious wakeups), a switch over of several users
  of cpufreq notifiers to QoS-based limits, a new devfreq driver for
  Tegra20, a new cpuidle driver and governor for virtualized guests, an
  extension of the wakeup sources framework to expose wakeup sources as
  device objects in sysfs, and more.

  Specifics:

   - Rework the main suspend-to-idle control flow to avoid repeating
     "noirq" device resume and suspend operations in case of spurious
     wakeups from the ACPI EC and decouple the ACPI EC wakeups support
     from the LPS0 _DSM support (Rafael Wysocki).

   - Extend the wakeup sources framework to expose wakeup sources as
     device objects in sysfs (Tri Vo, Stephen Boyd).

   - Expose system suspend statistics in sysfs (Kalesh Singh).

   - Introduce a new haltpoll cpuidle driver and a new matching governor
     for virtualized guests wanting to do guest-side polling in the idle
     loop (Marcelo Tosatti, Joao Martins, Wanpeng Li, Stephen Rothwell).

   - Fix the menu and teo cpuidle governors to allow the scheduler tick
     to be stopped if PM QoS is used to limit the CPU idle state exit
     latency in some cases (Rafael Wysocki).

   - Increase the resolution of the play_idle() argument to microseconds
     for more fine-grained injection of CPU idle cycles (Daniel
     Lezcano).

   - Switch over some users of cpuidle notifiers to the new QoS-based
     frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
     policy notifier events (Viresh Kumar).

   - Add new cpufreq driver based on nvmem for sun50i (Yangtao Li).

   - Add support for MT8183 and MT8516 to the mediatek cpufreq driver
     (Andrew-sh.Cheng, Fabien Parent).

   - Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson

Matthias Kaehlcke c0b64faf0f backlight: pwm_bl: Set scale type for brightness curves specified in the DT
Check if a brightness curve specified in the device tree is linear or
not and set the corresponding property accordingly. This makes the
scale type available to userspace via the 'scale' sysfs attribute.

To determine if a curve is linear it is compared to a interpolated linear
curve between min and max brightness. The curve is considered linear if
no value deviates more than +/-5% of ${brightness_range} from their
interpolated value.

Matthias Kaehlcke d55c028f8b backlight: Expose brightness curve type through sysfs
Backlight brightness curves can have different shapes. The two main
types are linear and non-linear curves. The human eye doesn't
perceive linearly increasing/decreasing brightness as linear (see
also 88ba95bedb "backlight: pwm_bl: Compute brightness of LED
linearly to human eye"), hence many backlights use non-linear (often
logarithmic) brightness curves. The type of curve currently is opaque
to userspace, so userspace often uses more or less reliable heuristics
(like the number of brightness levels) to decide whether to treat a
backlight device as linear or non-linear.

Export the type of the brightness curve via the new sysfs attribute
'scale'. The value of the attribute can be 'linear', 'non-linear' or
'unknown'. For devices that don't provide information about the scale
of their brightness curve the value of the 'scale' attribute is 'unknown'.

Peter Ujfalusi ec665b756e backlight: gpio-backlight: Correct initial power state handling
The default-on property - or the def_value via legacy pdata) should be
handled as:
if it is 1, the backlight must be enabled (kept enabled)
if it is 0, the backlight must be disabled (kept disabled)

This only works for the case when default-on is set. If it is not set then
the brightness of the backlight is set to 0. Now if the backlight is
enabled by external driver (graphics) the backlight will stay disabled since
the brightness is configured as 0. The backlight will not turn on.

In order to minimize screen flickering during device boot:

The initial brightness should be set to 1.

If booted in non DT mode or no phandle link to the backlight node:
follow the def_value/default-on to select UNBLANK or POWERDOWN

If in DT boot we have phandle link then leave the GPIO in a state which the
bootloader left it and let the user of the backlight to configure it
further.

Viresh Kumar 8c7d7b4bb1 video: pxafb: Remove cpufreq policy notifier
The cpufreq policy notifier's CPUFREQ_ADJUST notification is going to
get removed soon.

The notifier callback pxafb_freq_policy() isn't doing anything apart
from printing a debug message on CPUFREQ_ADJUST notification. There is
no point in keeping an otherwise empty callback and registering the
notifier.

Remove it.

Gustavo A. R. Silva 06b1f4b9f2 video: fbdev/mmp/core: Use struct_size() in kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct mmp_path {
	...
        struct mmp_overlay overlays[0];
};

size = sizeof(struct mmp_path) + count * sizeof(struct mmp_overlay);
instance = kzalloc(size, GFP_KERNEL)

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, overlays, count), GFP_KERNEL)

Notice that, in this case, variable size is not necessary, hence it
is removed.

This code was detected with the help of Coccinelle.

Hans de Goede 51677dfcc1 efifb: BGRT: Improve efifb_bgrt_sanity_check
For various reasons, at least with x86 EFI firmwares, the xoffset and
yoffset in the BGRT info are not always reliable.

Extensive testing has shown that when the info is correct, the
BGRT image is always exactly centered horizontally (the yoffset variable
is more variable and not always predictable).

This commit simplifies / improves the bgrt_sanity_check to simply
check that the BGRT image is exactly centered horizontally and skips
(re)drawing it when it is not.

This fixes the BGRT image sometimes being drawn in the wrong place.

Laurent Pinchart 1e938755fa video: omapfb2: Make standard and custom panel drivers mutually exclusive
Standard DRM panel drivers for several panels used by omapfb2 are now
available. Their module name clashes with the modules from
drivers/video/fbdev/omap2/omapfb/displays, part of the deprecated omapfb2
fbdev driver. As omapfb2 can only be compiled when the omapdrm driver is
disabled, and the DRM panel drivers are useless in that case, make the
omapfb2 panels depend on the standard DRM panels being disabled to fix
the name clash.

That EARLY_EVENT_BLANK is not used can be verified that no driver set any of:
