drivers: w1-gpio: add flag to force read-polling while delaying
On Pi 5, the link to RP1 will bounce in and out of L1 depending on
inactivity timers at both the RC and EP end. Unfortunately for
bitbashing 1-wire, this means that on an otherwise idle Pi 5 many of the
reads/writes to GPIO registers are delayed by up to 8us which causes
mis-sampling of read data and trashes write bits.
By issuing dummy reads at a rate greater than the link inactivity
timeout while spinning on a delay, PCIe stays in L0 which does not incur
additional latency.

ad83c7cb2f ("irqchip/irq-bcm2836: Add support for DT interrupt polarity")
changed the way that the BCM2836/7 local interrupts are mapped; instead
of being pre-mapped they are now mapped on-demand. A side effect of this
change is that the call to irq_of_parse_and_map from armctrl_of_init
creates a new mapping, forming a gap between the IRQs and the FIQs. This
gap breaks the FIQ<->IRQ mapping which up to now has been done by assuming:
1) that the value of FIQ_START is the same as the number of normal IRQs
that will be mapped (still true), and
2) that this value is also the offset between an IRQ and its equivalent
FIQ (which is no longer the case).
Remove both assumptions by measuring the interval between the last IRQ
and the last FIQ, passing it as the parameter to init_FIQ().

Device Tree - string properties where the name is the alias and the

drivers: irqchip: irq-bcm2835: Concurrency fix
The commit shown in Fixes: aims to improve interrupt throughput by
getting the handlers invoked on different CPU cores. It does so (*) by
using an irq_ack hook to change the interrupt routing.
Unfortunately, the IRQ status bits must be cleared at source, which only
happens once the interrupt handler has run - there is no easy way for
one core to claim one of the IRQs before sending the remainder to the
next core on the list, so waking another core immediately results in a
race with a chance of both cores handling the same IRQ. It is probably
for this reason that the routing change is deferred to irq_ack, but that
doesn't guarantee no clashes - after irq_ack is called, control returns
to bcm2836_chained_handler_irq which proceeds to check for other pending
IRQs at a time when the next core is probably doing the same thing.
Since the whole point of the original commit is to distribute the IRQ
handling, there is no reason to attempt to handle multiple IRQs in one
interrupt callback, so the problem can be solved (or at least made much
harder to reproduce) by changing a "while" into an "if", so that each
invocation only handles one IRQ.
(*) I'm not convinced it's as effective as claimed since irq_ack is
called _after_ the interrupt handler, but the author thought it made a
difference.

Pisound dynamic overlay (#1760)
Restructuring pisound-overlay.dts, so it can be loaded and unloaded dynamically using dtoverlay.
Print a logline when the kernel module is removed.
pisound improvements:
* Added a writable sysfs object to enable scripts / user space software
to blink MIDI activity LEDs for variable duration.
* Improved hw_param constraints setting.
* Added compatibility with S16_LE sample format.
* Exposed some simple placeholder volume controls, so the card appears
in volumealsa widget.
Add missing SND_PISOUND selects dependency to SND_RAWMIDI
Without it the Pisound module fails to compile.
See https://github.com/raspberrypi/linux/issues/2366
Updates for Pisound module code:
* Merged 'Fix a warning in DEBUG builds' (1c8b82b).
* Updating some strings and copyright information.
* Fix for handling high load of MIDI input and output.
* Use dual rate oversampling ratio for 96kHz instead of single

This patch adds a reset GPIO for the AudioInjector.net octo sound card.
Audioinjector octo : Make the playback and capture symmetric
This patch ensures that the sample rate and channel count of the audioinjector

audioinjector-octo: Add continuous clock feature

2. Fix the diagnostics in an error path of the soundcard driver to
correctly identify the reason for the failure to load.
3. Move the declaration of the clock node in the overlay outside
the I2C node to avoid warnings.
4. Sort the overlay nodes so that dependencies are only to earlier
fragments, in an attempt to get runtime dtoverlay application to
work (it still doesn't...)

IMO the Synopsys datasheet could be clearer in this area, but it seems
that the DMA data ports (DMATX and DMARX) expect left and right samples
in alternate writes; if a stereo pair is pushed in a single 32-bit
write, the upper half is ignored, leading to double speed audio with a
confused stereo image. Make sure the necessary changes happen by
updating the DMA configuration data in the hw_params method.
The set_bclk_ratio change was made at a time when it looked like it
could be causing an error, but I think the division of responsibilities
is clearer this way (and the kernel log clearer without the info-level

ASoC: dwc: Correct channel count reporting
The DWC I2S driver treats the channel count register values as if they
encode a power of two (2, 4, 8, 16), but they actually encode a
multiple of 2 (2, 4, 6, 8).
Also improve the error message when asked for an unsupported number
of channels.

performing the changes and then unmute it when an error occurs or the

ASoC: bcm: Use power-of-2 bclk_ratios
The soundcard drivers originally used snd_pcm_format_physical_width,
but a later commit changed that to snd_pcm_format_width because the
in-memory sample storage width should not be a factor in determining
the bclk_ratio. However, the physical width rounds the sample bits up
to the nearest power of 2, which makes it easier to find integer clock
divisors.
Restore the old behaviour, but with an implementation that makes it
clear what is going on.

Following [1], it becomes harder for the CPU DAI to know the correct

driver, or implement and use set_bclk_ratio on the codec. This commit
does the latter.

sound/soc: dwc-i2s: choose FIFO thresholds based on DMA burst constraints
Valid ranges for the I2S peripheral's FIFO configuration include a depth
of 16 - unconditionally setting the burst length to 16 with a fifo
threshold of size/2 will cause under/overflows.
For DMA engines with restricted capabilities the requested burst length
and FIFO thresholds need to be adjusted downward accordingly.
Both the RX and TX FIFOs operate on "less-than" thresholds. Setting the
TX threshold to fifo_size minus burst means the FIFO is kept nearly-full.

Fix copy_from_user if BCM2835_FAST_MEMCPY=n
The change which introduced CONFIG_BCM2835_FAST_MEMCPY unconditionally
changed the behaviour of arm_copy_from_user. The page pinning code
is not safe on ARMv7 if LPAE & high memory is enabled and causes
crashes which look like PTE corruption.
Make __copy_from_user_memcpy conditional on CONFIG_2835_FAST_MEMCPY=y
which is really an ARMv6 / Pi1 optimization and not necessary on newer
ARM processors.
arm: fix mmap unlocks in uaccess_with_memcpy.c
This is a regression that was added with the commit 192a4e923e as of rpi-5.8.y, since that is when the move to the mmap locking API was introduced - d8ed45c5dc
The issue is that when the patch to improve performance for the __copy_to_user and __copy_from_user functions were added for the Raspberry Pi, some of the mmaps were incorrectly mapped to write instead of read. This would cause a verity of issues, and in my case, prevent the booting of a squashfs filesystem on rpi-5.8-y and above.

The "input" trigger makes the associated GPIO an input. This is to support
the Raspberry Pi PWR LED, which is driven by external hardware in normal use.
N.B. pwr_led is not available on Model A or B boards.
leds-gpio: Implement the brightness_get method
The power LED uses some clever logic that means it is driven
by a voltage measuring circuit when configured as input, otherwise
it is driven by the GPIO output value. This patch wires up the
brightness_get method for leds-gpio so that user-space can monitor
the LED value via /sys/class/gpio/led1/brightness. Using the input
trigger this returns an indication of the system power health,
otherwise it is just whatever value the trigger has written most
recently.

firmware: bcm2835: Support ARCH_BCM270x
Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
Based on bcm2835-gpiomem.
We allow export of the "GPIO registers" to userspace via a chardev as
this allows for finer access control (e.g. users must be group gpio, root
not required).
This driver allows access to either rp1-gpiomem or gpiomem, depending on
which nodes are populated in devicetree.
RP1 has a different look-and-feel to BCM283x SoCs as it has split ranges
for IO controls and the parallel registered OE/IN/OUT access. To handle
this, the driver concatenates the ranges for an IO bank and the
corresponding RIO instance into a contiguous buffer.

N.B. Using miscdevice changes the udev SUBSYSTEM string, so a change
to the companion udev rule is required in order to continue to set
the correct device permissions, e.g.:
