three i.MX SoCs in here and that mostly means a lot of driver code and data.
Beyond that platform, there are some new Mediatek, Amlogic, and Qualcomm clk
drivers added in here, and then we get to the long tail of driver updates and
non-critical fixes all around, including code for vendors such as Renesas,
Rockchip, Nvidia, and Allwinner. Overall, the driver updates look normal.
Beyond the usual driver updates we have an update to make registering OF based
clk providers a little simpler when they're devices created as a child of a
device backed by a node in DT. Drivers don't have to jump through hoops to
unregister the provider upon driver removal anymore because the API does the
right thing and uses the parent device DT node.
Core:
- Make devm_of_clk_add_hw_provider() use parent dt node if necessary
- Various SPDX taggings
- Mark clk_ops const when possible
New Drivers:
- NXP i.MX7ULP SoC clock support
- NXP i.MX8QXP SoC clock support
- NXP i.MX8MQ SoC clock support
- NXP QorIQ T1023 SoC support
- Qualcomm SDM845 audio subsystem clks

- Qualcomm QCS404 RPM clk support
- Mediatek MT7629 SoC clk controllers
- Allwinner F1c100s SoC clocks
- Allwinner H6 display engine clocks
- Amlogic GX video clocks
- Support for Amlogic meson8b CPU frequency scaling
- Amlogic Meson8b CPU post-divider clocks
Updates:
- Proper suspend/resume on VersaClock5
- Shrink code some with DEFINE_SHOW_ATTRIBUTE()
- Register fixes for Rockchip rk3188 and rk3328
- One new critical clock for Rockchip rk3188 and a fixed clock id (double used number)
- New clock id for Rockchip rk3328
- Amlogic Meson8/Meson8b video clock support
- Amlogic got a clk-input helper and used it for the axg-audio clock driver

- Support for CPEX (timer) clocks on various Renesas R-Car Gen3 and RZ/G2 SoCs
- Support for SDHI HS400 clocks on early revisions of Renesas R-Car H3 and M3-W

The main thing this release has been a lot of work on the integration
with SPI NOR flashes, there's been some specific support for a while for
controller features designed to make them perform better but it's not
worked out as well as hoped so the interface has been redesigned in a
way that will hopefully do better - it's already been adopted by a
number of additional controllers so things are looking good. Otherwise
most of the work has been driver specific:
- Support for better integration with NOR flashes from Boris Brezillon
and Yogesh Narayan Gaur plus usage of it in several drivers.
- A big cleanup of the Rockchip driver from Emil Renner Berthing.
- Lots of performance improvements for bcm2835 from Lukas Wunner.
- Slave mode support for pxa2xx from Lubomir Rintel.

There are no intensive changes in both ALSA and ASoC core parts while
rather most of changes are a bunch of driver fixes and updates.
A large diff pattern appears in ASoC TI part which now merges both
OMAP and DaVinci stuff, but the rest spreads allover the places.
Note that this pull request includes also some updates for LED trigger
and platform drivers for mute LEDs, appearing in the diffstat as well.
Some highlights:
ASoC:
- Preparatory work for merging the audio-graph and audio-graph-scu
cards
- A merge of TI OMAP and DaVinci directories, as both product lines
get merged together. Also including a few architecture changes as
well.
- Major cleanups of the Maxim MAX9867 driver
- Small fixes for tablets & co with Intel BYT/CHT chips
- Lots of rsnd updates as usual
- Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S
controllers
HD-audio:

dynamic binding
- Huawei WMI hotkey and mute LED support
- Refactoring of PM code and display power controls
- Headset button support in the generic jack code
- A few updates for Tegra
- Fixups for HP EliteBook and ASUS UX391UA
- Lots of updates for Intel ASoC HD-audio, including the improved DSP

"The biggest part is a series of reverts for the macro based GCC
inlining workarounds. It caused regressions in distro build and other
kernel tooling environments, and the GCC project was very receptive to
fixing the underlying inliner weaknesses - so as time ran out we
decided to do a reasonably straightforward revert of the patches. The
plan is to rely on the 'asm inline' GCC 9 feature, which might be
backported to GCC 8 and could thus become reasonably widely available
on modern distros.
Other than those reverts, there's misc fixes from all around the
place.

Some interrupt controllers whose interrupts are acked on read will set
the status bits for masked interrupts without changing the state of
the IRQ line.
Some chips have an additional "feature" where if those set bits are
not cleared before unmasking their respective interrupts, the IRQ
line will change the state and we'll interpret this as an interrupt
although it actually fired when it was masked.
Add a new field to the irq chip struct that tells the regmap irq chip
code to always clear the status registers before actually changing the
irq mask values.

Add level active IRQ support to regmap-irq irqchip. Change breaks
existing regmap-irq type setting. Convert the existing drivers which
use regmap-irq with trigger type setting (gpio-max77620) to work
with this new approach. So we do not magically support level-active
IRQs on gpio-max77620 - but add support to the regmap-irq for chips
which support them =)
We do not support distinguishing situation where HW supports rising
and falling edge detection but not both. Separating this would require
inventing yet another flags for IRQ types.

PM-runtime uses the timer infrastructure for autosuspend. This implies
that the minimum time before autosuspending a device is in the range
of 1 tick included to 2 ticks excluded
-On arm64 this means between 4ms and 8ms with default jiffies
configuration
-And on arm, it is between 10ms and 20ms
These values are quite high for embedded systems which sometimes want
the duration to be in the range of 1 ms.
It is possible to switch autosuspend over to using hrtimers to get
finer granularity for short durations and take advantage of slack to
retain some margins and get long timeouts with minimum wakeups.
On an arm64 platform that uses 1ms for autosuspending timeout of its
GPU, idle power is reduced by 10% with hrtimer.
The latency impact on arm64 hikey octo cores is:
- mark_last_busy: from 1.11 us to 1.25 us
- rpm_suspend: from 15.54 us to 15.38 us
[Only the code path of rpm_suspend() that starts hrtimer has been
measured.]
arm64 image (arm64 default defconfig) decreases by around 3KB
with following details:
$ size vmlinux-timer
text data bss dec hex filename
12034646 6869268 386840 19290754 1265a82 vmlinux
$ size vmlinux-hrtimer
text data bss dec hex filename
12030550 6870164 387032 19287746 1264ec2 vmlinux
The latency impact on arm 32bits snowball dual cores is :
- mark_last_busy: from 0.31 us usec to 0.77 us
- rpm_suspend: from 6.83 us to 6.67 usec
The increase of the image for snowball platform that I used for
testing performance impact, is neglictable (244B).

Not much work on the core this time around but we've seen quite a bit of
driver work, including on the generic DT drivers. There's also a large
part of the diff from a merge of the DaVinci and OMAP directories, along
with some active development there:
- Preparatory work from Morimoto-san for merging the audio-graph and
audio-graph-scu cards.
- A merge of the TI OMAP and DaVinci directories, the OMAP product line
has been merged into the DaVinci product line so there is now a lot
of IP sharing which meant that the split directories just got in the
way. This has pulled in a few architecture changes as well.
- A big cleanup of the Maxim MAX9867 driver from Ladislav Michl.
- Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S
controllers.

Presently the arches arm64, arm and sh have a function which loops
through each memblock and calls memory present. riscv will require a
similar function.
Introduce a common memblocks_present() function that can be used by all
the arches. Subsequent patches will cleanup the arches that make use of
this.

This define is used by arm64 to calculate the size of the vmemmap
region. It is defined as the log2 of the upper bound on the size of a
struct page.
We move it into mm_types.h so it can be defined properly instead of set
and checked with a build bug. This also allows us to use the same
define for riscv.

Macros 'inline' and '__gnu_inline' used to be defined in compiler-gcc.h,
which was (and is) included entirely in (__KERNEL__ && !__ASSEMBLY__).
Commit 815f0ddb34 ("include/linux/compiler*.h: make compiler-*.h mutually
exclusive") had those macros exposed to userspace, unintentionally.
Then commit a3f8a30f3f ("Compiler Attributes: use feature checks
instead of version checks") moved '__gnu_inline' back into
(__KERNEL__ && !__ASSEMBLY__) and 'inline' was left behind. Since 'inline'
depends on '__gnu_inline', compiling error showing "unknown type name
‘__gnu_inline’" will pop up, if userspace somehow includes
<linux/compiler.h>.
Other macros like __must_check, notrace, etc. are in a similar situation.
So just move all these macros back into (__KERNEL__ && !__ASSEMBLY__).
Note:
1. This patch only affects what userspace sees.
2. __must_check (when !CONFIG_ENABLE_MUST_CHECK) and noinline_for_stack
were once defined in __KERNEL__ only, but we believe that they can
be put into !__ASSEMBLY__ too.

Pull more operating performance points (OPP) framework changes for v4.21
from Viresh Kumar:
"- Fix missing OPP debugfs directory (Viresh Kumar).
- Make genpd performance states orthogonal to idlestates (Ulf
Hansson).
- Propagate performance state changes from genpd to its master (Viresh
Kumar).
- Minor improvement of some OPP helpers (Viresh Kumar)."
* 'opp/linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm:
PM / Domains: Propagate performance state updates
PM / Domains: Factorize dev_pm_genpd_set_performance_state()
PM / Domains: Save OPP table pointer in genpd
OPP: Don't return 0 on error from of_get_required_opp_performance_state()
OPP: Add dev_pm_opp_xlate_performance_state() helper
OPP: Improve _find_table_of_opp_np()
PM / Domains: Make genpd performance states orthogonal to the idlestates
OPP: Fix missing debugfs supply directory for OPPs
OPP: Use opp_table->regulators to verify no regulator case
Currently a genpd only handles the performance state requirements from
the devices under its control. This commit extends that to also handle
the performance state requirement(s) put on the master genpd by its
sub-domains. There is a separate value required for each master that
the genpd has and so a new field is added to the struct gpd_link
(link->performance_state), which represents the link between a genpd and
its master. The struct gpd_link also got another field
prev_performance_state, which is used by genpd core as a temporary
variable during transitions.
On a call to dev_pm_genpd_set_performance_state(), the genpd core first
updates the performance state of the masters of the device's genpd and
then updates the performance state of the genpd. The masters do the same
and propagate performance state updates to their masters before updating
their own. The performance state transition from genpd to its master is
done with the help of dev_pm_opp_xlate_performance_state(), which looks
at the OPP tables of both the domains to translate the state.

dev_pm_genpd_set_performance_state() will be required to call
dev_pm_opp_xlate_performance_state() going forward to translate from
performance state of a sub-domain to performance state of its master.
And dev_pm_opp_xlate_performance_state() needs pointers to the OPP
tables of both genpd and its master.
Lets fetch and save them while the OPP tables are added. Fetching the
OPP tables should never fail as we just added the OPP tables and so add
a WARN_ON() for such a bug instead of full error paths.

of_get_required_opp_performance_state() returns 0 on errors currently
and a positive performance state otherwise. Since 0 is a valid
performance state (representing off), it would be better if this routine
returns negative values on error.
That will also make it behave similar to
dev_pm_opp_xlate_performance_state(), which also returns performance
states and returns negative values on error. Change the return type of
the function to "int" in order to return negative values.
This doesn't have any users for now and so no other part of the kernel
will be impacted with this change.

dev_pm_genpd_set_performance_state() needs to handle performance state
propagation going forward. Currently this routine only gets the required
performance state of the device's genpd as an argument, but it doesn't
know how to translate that to master genpd(s) of the device's genpd.
Introduce a new helper dev_pm_opp_xlate_performance_state() which will
be used to translate from performance state of a device (or genpd
sub-domain) to another device (or master genpd).
Normally the src_table (of genpd sub-domain) will have the
"required_opps" property set to point to one of the OPPs in the
dst_table (of master genpd), but in some cases the genpd and its master
have one to one mapping of performance states and so none of them have
the "required-opps" property set. Return the performance state of the
src_table as it is in such cases.
