2025-10-22PM: EM: Add em.yaml and autogen filesChangwoo Min
Add a generic netlink spec in YAML format and autogenerate boilerplate code using ynl-regen.sh to introduce a generic netlink for the energy model. It allows a userspace program to read the performance domain and its energy model. It notifies the userspace program when a performance domain is created or deleted or its energy model is updated through a multicast interface. Specifically, it supports two commands: - EM_CMD_GET_PDS: Get the list of information for all performance domains. - EM_CMD_GET_PD_TABLE: Get the energy model table of a performance domain. Also, it supports three notification events: - EM_CMD_PD_CREATED: When a performance domain is created. - EM_CMD_PD_DELETED: When a performance domain is deleted. - EM_CMD_PD_UPDATED: When the energy model table of a performance domain is updated. Finally, update MAINTAINERS to include new files.

Merge series from Troy Mitchell <troy.mitchell@linux.spacemit.com>: On the K1 SoC, there is a full-duplex I2S controller. The I2S is programmable, with the sample width configurable to 8, 16, 18, or 32 bits. A dedicated FIFO is provided for transmit (TXFIFO) and another for receive (RXFIFO). In non-packed mode, both FIFOs are 32 entries deep and 32 bits wide, giving a total of 32 samples each.

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].

2025-10-21dt-bindings: gpu: img,powervr-rogue: Rework the allOf sectionMarek Vasut
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.

2025-10-21documentation: 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>

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.
