2025-10-21dt-bindings: soc: microchip: document the simple-mfd syscon on PolarFire SoCConor Dooley
"mss-top-sysreg" contains clocks, pinctrl, resets, an interrupt controller and more. At this point, only the reset controller child is described as that's all that is described by the existing bindings. The clock controller already has a dedicated node, and will retain it as there are other clock regions, so like the mailbox, a compatible-based lookup of the syscon is sufficient to keep the clock driver working as before, so no child is needed. There's also an interrupt multiplexing service provided by this syscon, for which there is work in progress at [1].

Rework the current allOf: section such that all handling of clocks/clock-names properties happens first, and all handling of power-domains/power-domain-names happens second. This allows the allOf section to limit various GPU models to matching clocks count in the first half, and apply the same for power-domains count in the second half, without conflating the two limits together. This makes addition of GPU models with different clocks and power-domains count easier. No functional change intended.

2025-10-21dt-bindings: net: airoha: Add AN7583 supportLorenzo Bianconi
Introduce AN7583 ethernet controller support to Airoha EN7581 device-tree bindings. The main difference between EN7581 and AN7583 is the number of reset lines required by the controller (AN7583 does not require hsi-mac).

2025-10-21documentation: seqlock: fix the wrong documentation of ↵Oleg Nesterov
read_seqbegin_or_lock/need_seqretry The comments and pseudo code in Documentation/locking/seqlock.rst are wrong: int seq = 0; do { read_seqbegin_or_lock(&foo_seqlock, &seq); /* ... [[read-side critical section]] ... */ } while (need_seqretry(&foo_seqlock, seq)); read_seqbegin_or_lock() always returns with an even "seq" and need_seqretry() doesn't change this counter. This means that seq is always even and thus the locking pass is simply impossible. IOW, "_or_lock" has no effect and this code doesn't differ from do { seq = read_seqbegin(&foo_seqlock); /* ... [[read-side critical section]] ... */ } while (read_seqretry(&foo_seqlock, seq)); Signed-off-by: Oleg Nesterov <oleg@redhat.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org>
2025-10-21leds: lp55xx_common: Enable use without FW_LOADER_USER_HELPERSicelo A. Mhlongo
Many distributions disable FW_LOADER_USER_HELPER, and this configuration makes lp55xx LEDs completely unusable. Enable their use by only implying the user helper, since the basic LEDs and the hardware patterns can be used with only the sysfs interface. Tested on Nokia N900 with LP5523. Additionally do not refer to the sysfs interface as legacy anymore, since it might be the only one available to users. Signed-off-by: Sicelo A.

2025-10-21dt-bindings: leds: Add default-brightness property to common.yamlJean-François Lessard
Add default-brightness property to leds/common.yaml to establish a single canonical definition for LED brightness initialization. The property is currently defined locally in leds/leds-pwm.yaml and is needed by auxdisplay/titanmec,tm16xx.yaml. Properties should be defined in only one location to avoid type inconsistencies across bindings.

Convert the PCI mediatek Documentation to YAML schema to enable validation of the supported GEN1/2 Mediatek PCIe controller. While converting, lots of cleanup were done from the .txt with better specifying what is supported by the various PCIe controller variant and drop of redundant info that are part of the standard PCIe Host Bridge schema. To reduce schema complexity the .txt is split in 2 YAML, one for mt7623/mt2701 and the other for every other compatible.
