8fa72836be mtd: rawnand: sunxi: do not count BBM bytes twice
BBM is already part of USER_DATA section, so we should not remove it twice

This was working ok because we are on the safe size, advertising that
there was 2 bytes less available than in reality.

But we can't change old platforms, since it may lead to a different ECC
strength, so, introduce a legacy flag for old platforms, and switch the
new platforms to the correct count.

848c13996c mtd: rawnand: sunxi: fix sunxi_nfc_hw_ecc_read_extra_oob
When dumping the OOB, the bytes at the end where actually copied from
the beginning of the OOB instead of current_offset.

That leads to something like:
OOB: ff ff ff ff ff ff ff ff ea 19 00 3a 83 db aa 8d
OOB: 99 09 c8 9a 90 36 35 7d aa 15 13 07 3d 97 b2 a4
OOB: a8 bb 19 b3 07 e9 f6 25 52 d7 1a 23 e2 7e 0a e4
OOB: 52 8a 09 d2 1a 86 3d cf b4 99 43 13 d3 90 33 0b
OOB: ff ff ff ff ff ff ff ff ea 19 00 3a 83 db aa 8d
OOB: 99 09 c8 9a 90 36 35 7d aa 15 13 07 3d 97 b2 a4
OOB: a8 bb 19 b3 07 e9 f6 25 52 d7 1a 23 e2 7e 0a e4
OOB: 52 8a 09 d2 1a 86 3d cf b4 99 43 13 d3 90 33 0b
instead of:
OOB: ff ff ff ff ff ff ff ff ea 19 00 3a 83 db aa 8d
OOB: 99 09 c8 9a 90 36 35 7d aa 15 13 07 3d 97 b2 a4
OOB: a8 bb 19 b3 07 e9 f6 25 52 d7 1a 23 e2 7e 0a e4
OOB: 52 8a 09 d2 1a 86 3d cf b4 99 43 13 d3 90 33 0b
OOB: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
OOB: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
OOB: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
OOB: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
(example with BCH16, user data [8,0], no scrambling)

*cur_off (offset from the beginning of the page) was compared to offset
(offset from the beginning of the OOB), and then, the
nand_change_read_column_op() sets the current position to the beginning
of the OOB instead of OOB+offset

The available length is really USER_DATA_LEN - 2 instead of just 2 (the

USER_DATA_LEN being 4, that doesn't change anything now, but if

87a70013be MAINTAINERS: Update GPU driver maintainer information
I and Qianhai are GPU R&D engineers at Loongson, specializing
in kernel driver development. We understand that the current
Loongson GPU driver lacks dedicated maintenance resources
because of some reasons.

As Loongson GPU driver developers, we have both the capability
and the responsibility to continuously maintain the Loongson
GPU driver, ensuring minimal impact on its users. After internal
discussions, our team has decided to recommend me and Qianhai
to take over the maintenance responsibilities, and recommend
Huacai, Mingcong and Ruoyao to help to review.

And We'll continue to maintain it for current supported chips
and drive future updates according to chip support plan.

9886005f89 drm/simple-kms: Deprecate simple-kms helpers
Deprecate simple-encoder and simple-display-pipe helpers in favor of
regular atomic helpers. Remove the related documentation. Add TODO
item for converting the remaining drivers.

These helpers have been deprecated for years and many drivers have
been updated to not use them. Still there are a few left and we
occasionally receive new drivers build upon them. Marking them as
deprecated will hopefully resolve these problems. The TODO items
should be easy enough for getting new voluteers started on DRM driver
development.

514c8451fc drm/mipi-dbi: Only modify planes on enabled CRTCs
Use drm_atomic_helper_commit_tail_rpm() as commit tail to update the
plane after enabling the CRTC. Then remove the plane-update code from
mipi_dbi_enable_flush() and inline the remaining backlight code where
necessary.

Mipi-dbi's current commit tail drm_atomic_helper_commit_tail() first
updates the plane and then enables the CRTC. But the CRTC enablement
includes power management that prevents the initial plane update from
working. Hence, each mipi-dbi driver includes a plane update in their
CRTC enablement; in the form of mipi_dbi_enable_flush() or custom code.

Using drm_atomic_helper_commit_tail_rpm() enables the CRTC before any
plane updates. Hence the additional plane update can be removed from
mipi_dbi_enable_flush() and a number of drivers.

This leaves backlight_enable() in the helper, which can now be inlined
into affected drivers. Drivers now enable the CRTC plus an optional
backlight and then automatically update the plane.

In the case of disabling the display, drm_atomic_helper_commit_tail_rpm()
only disables the CRTC without touching the plane at all. Mipi-dbi's
mipi_dbi_pipe_disable() already contains the necessary logic.

Removing the plane update from the CRTC enablement will also help with
converting mipi-dbi from simple-pipe helpers to regular atomic helpers.

bf08749a6a hwmon: (adm1177) fix sysfs ABI violation and current unit conversion
The adm1177 driver exposes the current alert threshold through
hwmon_curr_max_alarm. This violates the hwmon sysfs ABI, where
*_alarm attributes are read-only status flags and writable thresholds
must use currN_max.

The driver also stores the threshold internally in microamps, while
currN_max is defined in milliamps. Convert the threshold accordingly
on both the read and write paths.

Widen the cached threshold and related calculations to 64 bits so
that small shunt resistor values do not cause truncation or overflow.
Also use 64-bit arithmetic for the mA/uA conversions, clamp writes
to the range the hardware can represent, and propagate failures from
adm1177_write_alert_thr() instead of silently ignoring them.

Update the hwmon documentation to reflect the attribute rename and
the correct units returned by the driver.

16fb8d8a0e cpufreq: acpi-cpufreq: use DMI max speed when CPPC is unavailable
On AMD Ryzen Embedded V1780B (Family 17h, Zen 1), the BIOS does not
provide ACPI _CPC objects and the CPU does not support MSR-based CPPC
(X86_FEATURE_CPPC).  The _PSS table only lists nominal P-states
(P0 = 3350 MHz), so when get_max_boost_ratio() fails at
cppc_get_perf_caps(), cpuinfo_max_freq reports only the base frequency
instead of the rated boost frequency (3600 MHz).

  dmesg:
    ACPI CPPC: No CPC descriptor for CPU:0
    acpi_cpufreq: CPU0: Unable to get performance capabilities (-19)

cppc-cpufreq already has a DMI fallback (cppc_get_dmi_max_khz()) that
reads the processor max speed from SMBIOS Type 4.  Export it and reuse
it in acpi-cpufreq as a last-resort source for the boost frequency.

A sanity check ensures the DMI value is above the _PSS P0 frequency
and within 2x of it; values outside that range are ignored and the
existing arch_set_max_freq_ratio() path is taken instead.  The 2x
upper bound is based on a survey of the AMD Ryzen Embedded V1000
series, where the highest boost-to-base ratio is 1.8x (V1404I:
2.0 GHz base / 3.6 GHz boost).

The DMI lookup and sanity check are wrapped in a helper,
acpi_cpufreq_resolve_max_freq(), which falls through to
arch_set_max_freq_ratio() if the DMI value is absent or
out of range.

Tested on AMD Ryzen Embedded V1780B with v7.0-rc4:

  Before: cpuinfo_max_freq = 3350000 (base only)
  After:  cpuinfo_max_freq = 3600000 (includes boost)

9b776ddcf3 ACPI: PPTT: Remove duplicate structure, acpi_pptt_cache_v1_full
acpi_pptt_cache_v1_full was initially added as a stop gap until the
equivalent structure imported from ACPICA, acpi_pptt_v1 in actbl2.h,
contained all the fields of the Cache Type Structure.

Since commit 091c4af356 ("ACPICA: ACPI 6.4: PPTT: include all
fields in subtable type1"), acpi_pptt_v1 contains all these fields
making acpi_pptt_cache_v1_full redundant.

Remove acpi_pptt_cache_v1_full.

No functional change intended.

630bbba45c drbd: use genl pre_doit/post_doit
Every doit handler followed the same pattern: stack-allocate an
adm_ctx, call drbd_adm_prepare() at the top, call drbd_adm_finish()
at the bottom. This duplicated boilerplate across 25 handlers and
made error paths inconsistent, since some handlers could miss sending
the reply skb on early-exit paths.

The generic netlink framework already provides pre_doit/post_doit
hooks for exactly this purpose. An old comment even noted "this
would be a good candidate for a pre_doit hook".

Use them:

- pre_doit heap-allocates adm_ctx, looks up per-command flags from a
  new drbd_genl_cmd_flags[] table, runs drbd_adm_prepare(), and
  stores the context in info->user_ptr[0].
- post_doit sends the reply, drops kref references for
  device/connection/resource, and frees the adm_ctx.
- Handlers just receive adm_ctx from info->user_ptr[0], set
  reply_dh->ret_code, and return. All teardown is in post_doit.
- drbd_adm_finish() is removed, superseded by post_doit.

30eedf2446 mfd: ezx-pcap: Avoid rescheduling after destroying workqueue
Driver allocates workqueue and then registers additional interrupt
handler with devm interface.  This means that device removal will not
use a reversed order, but first destroy workqueue and then, via devm
release handlers, free the interrupt.

The interrupt handler registered with devm does not directly
use/schedule work items on the workqueue and the remove() function
correctly removes other IRQs handlers, however the code mixing devm and
non-devm interfaces is difficult to analyze and read.

Make the code flow much more obvious by using devm interface for
allocating the workqueue, so it will be freed with the rest of devm
resources.

Change is not equivalent in the workqueue itself: use non-legacy API
which does not set (__WQ_LEGACY | WQ_MEM_RECLAIM).  The workqueue is
used to update device registers, thus there is no point to run it for
memory reclaim.
