There are no platforms using the driver with platform data (no board
files with the driver), so the dead code can be dropped.

The driver was reporting POWER_SUPPLY_PROP_ONLINE via platform data
functions or '1' if no platform data was provided. Since there are no
platforms using the driver with platform data (no board files with the
driver), the online property can be simplified to always return '1'.

The driver was reporting POWER_SUPPLY_PROP_STATUS via platform data
functions. Without platform data, the max17040_get_status() functions
returns early with POWER_SUPPLY_STATUS_UNKNOWN. Since there are no
platforms using the driver with platform data (no board files with the
driver), the status property was always unknown.

When devm_ioremap_resource() fails, a clear enough error message will be
printed by its subfunction __devm_ioremap_resource(). The error
information contains the device name, failure cause, and possibly resource
information.
Therefore, remove the error printing here to simplify code and reduce the
binary size.

The fuel gauge in the RT5033 PMIC has its own I2C bus and interrupt
line. Therefore, it is not actually part of the RT5033 MFD and needs
its own of_match_table to probe properly.
Also, given that it's independent of the MFD, there is actually
no need to make the Kconfig depend on MFD_RT5033. Although the driver
uses the shared <linux/mfd/rt5033.h> header, there is no compile
or runtime dependency on the RT5033 MFD driver.

The RT5033 PMIC provides a simple fuel gauge via I2C.
Add a DT schema to describe how to set it up in the device tree.
Note that although RT5033 is a MFD with lots of functionality
(also charger, regulator, LEDs, ...) the fuel gauge has a separate
I2C bus and is not part of the MFD.

The only known BD70528 use-cases are such that the PMIC is controlled
from separate MCU which is not running Linux. I am not aware of
any Linux driver users. Furthermore, it seems there is no demand for
this IC. Let's ease the maintenance burden and drop the driver. We can
always add it back if there is sudden need for it.

Interrupt line can be configured on different hardware in different way,
even inverted. Therefore driver should not enforce specific trigger
type - edge falling - but instead rely on Devicetree to configure it.
The Maxim 14577/77836 datasheets describe the interrupt line as active
low with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.

The Maxim 17047/77693 datasheets describe the interrupt line as active

The interrupt line is shared between PMIC and RTC driver, so using level
sensitive interrupt is here especially important to avoid races. With
an edge configuration in case if first PMIC signals interrupt followed
shortly after by the RTC, the interrupt might not be yet cleared/acked
thus the second one would not be noticed.

Currently sbs-battery supports three string properties -
manufacturer, model_name, and chemistry. Buffers for those
properties are currently defined as global variables.
This patch moves those global variables into struct sbs_info
and cache/reuse them as they are all constant values.

The code was calling ab8500_bm_of_probe() in four different
spots effectively overwriting the same configuration three
times. This was done because probe order was uncertain.

The driver has problems with the different components of
the charging code racing with each other to probe().
This results in all four subdrivers populating battery
information to ascertain that it is populated for their
own needs for example.
Fix this by using component probing and thus expressing
to the kernel that these are dependent components.
The probes can happen in any order and will only acquire
resources such as state container, regulators and
interrupts and initialize the data structures, but no
execution happens until the .bind() callback is called.
The charging driver is the main component and binds
first, then bind in order the three subcomponents:
ab8500-fg, ab8500-btemp and ab8500-chargalg.
Do some housekeeping while we are moving the code around.
Like use devm_* for IRQs so as to cut down on some
boilerplate.

Convert the binding to DT schema format.
I slightly modified the binding by allowing regulator-[0-9] and cable-[0-9]
instead of regulator@[0-9] and cable@[0-9], so that DT compiler does not
complain about missing 'reg' property. The driver actually ignores the
nodename and can handle both styles.

Commit b9d79e4ca4ff ("fbmem: Mark proc_fb_seq_ops as __maybe_unused")
places the '__maybe_unused' in an entirely incorrect location between
the "struct" keyword and the structure name.
It's a wonder that gcc accepts that silently, but clang quite reasonably
warns about it:

Pull scheduler fixes from Thomas Gleixner:
"A set of scheduler updates:
- Prevent PSI state corruption when schedule() races with cgroup
move.
A recent commit combined two PSI callbacks to reduce the number of
cgroup tree updates, but missed that schedule() can drop rq::lock
for load balancing, which opens the race window for
cgroup_move_task() which then observes half updated state.
The fix is to solely use task::ps_flags instead of looking at the
potentially mismatching scheduler state
- Prevent an out-of-bounds access in uclamp caused bu a rounding
division which can lead to an off-by-one error exceeding the
buckets array size.
- Prevent unfairness caused by missing load decay when a task is
attached to a cfs runqueue.

Mounting with "multichannel" is obviously implied if user requested
more than one channel on mount (ie mount parm max_channels>1).
Currently both have to be specified. Fix that so that if max_channels
is greater than 1 on mount, enable multichannel rather than silently
falling back to non-multichannel.

We were ignoring CAP_MULTI_CHANNEL in the server response - if the
server doesn't support multichannel we should not be attempting it.

Pull powerpc updates and fixes from Michael Ellerman:
"A bit of a mixture of things, tying up some loose ends.
There's the removal of the nvlink code, which dependend on a commit in
the vfio tree. Then the enablement of huge vmalloc which was in next
for a few weeks but got dropped due to conflicts. And there's also a
few fixes.
Summary:
- Remove the nvlink support now that it's only user has been removed.
- Enable huge vmalloc mappings for Radix MMU (P9).
- Fix KVM conversion to gfn-based MMU notifier callbacks.
- Fix a kexec/kdump crash with hot plugged CPUs.
- Fix boot failure on 32-bit with CONFIG_STACKPROTECTOR.
- Restore alphabetic order of the selects under CONFIG_PPC.
Thanks to: Christophe Leroy, Christoph Hellwig, Nicholas Piggin,
Sandipan Das, and Sourabh Jain"

In the SMB3/SMB3.1.1 negotiate protocol request, we are supposed to
advertise CAP_MULTICHANNEL capability when establishing multiple
channels has been requested by the user doing the mount. See MS-SMB2
sections 2.2.3 and 3.2.5.2
Without setting it there is some risk that multichannel could fail
if the server interpreted the field strictly.

Pull networking fixes from Jakub Kicinski:
"Networking fixes for 5.13-rc1, including fixes from bpf, can and
netfilter trees. Self-contained fixes, nothing risky.
Current release - new code bugs:
- dsa: ksz: fix a few bugs found by static-checker in the new driver
- stmmac: fix frame preemption handshake not triggering after
interface restart
Previous releases - regressions:
- make nla_strcmp handle more then one trailing null character
- fix stack OOB reads while fragmenting IPv4 packets in openvswitch
and net/sched
- sctp: do asoc update earlier in sctp_sf_do_dupcook_a
- sctp: delay auto_asconf init until binding the first addr
- stmmac: clear receive all(RA) bit when promiscuous mode is off
- can: mcp251x: fix resume from sleep before interface was brought up
Previous releases - always broken:
- bpf: fix leakage of uninitialized bpf stack under speculation
- bpf: fix masking negation logic upon negative dst register
- netfilter: don't assume that skb_header_pointer() will never fail
- only allow init netns to set default tcp cong to a restricted algo
- xsk: fix xp_aligned_validate_desc() when len == chunk_size to avoid
false positive errors
- ethtool: fix missing NLM_F_MULTI flag when dumping
- can: m_can: m_can_tx_work_queue(): fix tx_skb race condition
- sctp: fix a SCTP_MIB_CURRESTAB leak in sctp_sf_do_dupcook_b

<linux/kconfig.h> is included from all the kernel-space source files,
including C, assembly, linker scripts. It is intended to contain a
minimal set of macros to evaluate CONFIG options.
IF_ENABLED() is an intruder here because (x ? y : z) is C code, which
should not be included from assembly files or linker scripts.
Also, <linux/kconfig.h> is no longer self-contained because NULL is
defined in <linux/stddef.h>.
Move IF_ENABLED() out to <linux/kernel.h> as PTR_IF(). PTF_IF()
takes the general boolean expression instead of a CONFIG option
so that it fits better in <linux/kernel.h>.

Merge master back into next, this allows us to resolve some conflicts in
arch/powerpc/Kconfig, and also re-sort the symbols under config PPC so
that they are in alphabetical order again.
