2025-10-21ASoC: spacemit: add i2s support to K1 SoCMark Brown1-0/+87
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 Dooley1-0/+47
"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.

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); /* ...

2025-10-20dt-bindings: dma: snps,dw-axi-dmac: Add iommu propertyKhairul Anuar Romli1-0/+3
Agilex5 integrates an ARM SMMU v3 (System Memory Management Unit) with dedicated Translation Buffer Units (TBUs) assigned to various peripherals, including the Synopsys DesignWare AXI DMA controller. Each TBU handles address translation for its associated device by mapping stream IDs to memory access permissions and virtual-to-physical address mappings via the SMMU core. The DesignWare AXI DMAC instances on Agilex5 are connected to their respective TBUs. These TBUs forward DMA transactions from the controller through the SMMU, enabling IOMMU-based features such as: - Address translation for DMA operations - Isolation and protection of memory regions accessed by the DMA controller - Support for secure and virtualized environments through enforced access control To support this configuration, the `iommus` property must be added to the binding schema for `snps,dw-axi-dmac`. This allows the device tree to associate each DMA controller with the correct SMMU stream ID, enabling the Linux IOMMU framework to configure translation contexts at runtime. This change documents the IOMMU support for the DMA controller on Agilex5 and allows proper integration with the SMMUv3 hardware.

Agilex5 integrates an ARM SMMU (System Memory Management Unit) with Translation Buffer Units (TBUs) assigned to various peripherals, including the NAND controller. The Cadence HP NAND controller ("cdns,hp-nfc") on Agilex5 is behind a TBU connected to the system's SMMUv3. To support this, the controller requires an `iommus` property in the device tree to properly configure address translation through the IOMMU framework. Adding the `iommus` property to the binding schema allows the OS to associate the NAND controller with its corresponding SMMU stream ID. This enables: - DMA address translation between the controller and system memory - Memory protection for NAND operations - Proper functioning of the IOMMU framework in secure or virtualized environments This change documents the IOMMU integration for the NAND controller on platforms like Agilex5 where such hardware is present.

2025-10-19dt-bindings: iio: health: max30100: Add LED pulse-width propertyShrikant Raskar1-0/+8
The LED pulse width on the MAX30100 sensor determines how long the IR/Red LEDs are driven during each sample, directly affecting the emitted optical energy and hence the received signal amplitude. This parameter is highly dependent on the mechanical and optical integration of the sensor, such as: - The type and thickness of the optical window or lens covering the sensor. - The distance between the LED and photodiode. - The reflectivity of the target surface. For example: - A smartwatch or wearable ring with a thin glass window can operate with shorter pulses (200-400 us) to save power. - A medical-grade pulse oximeter or sensor mounted behind a thicker protective layer may require longer pulses (800-1600 us) for reliable signal amplitude. Because this configuration is determined by hardware design rather than by runtime conditions, it is appropriate to describe it in the DT. If not specified, the driver defaults to 1600 us to maintain existing behavior. Tested on: Raspberry Pi 3B + MAX30100 breakout board.
