2026-04-29Documentation: gpu: nova: document the IFR header layoutTimur Tabi
Init-from-ROM (IFR) is a special GPU feature used for power management on some Nvidia GPUs. It references data in the VBIOS for its operation, but for drivers the important piece is the header that precedes the VBIOS PCI Expansion ROM. Parsing VBIOS is necessary to boot GSP-RM on Turing, Ampere, and Ada GPUs. Most such GPUs do not need to parse the IFR header in order to find the VBIOS, but the Nvidia GA100 is the exception. GA100 lacks a display engine, so the PRAMIN method (which reads the VBIOS from VRAM via display hardware) is unavailable, forcing the driver to read the ROM directly via PROM. On other similar GPUs, either PRAMIN succeeds before PROM is tried, or the IFR hardware has already applied the ROM offset so that PROM reads transparently skip the IFR header. Note that GH100 also does not have a display engine, but it uses a completely different method to boot GSP-RM. This information is derived from NVIDIA's open-source GPU kernel module driver (aka OpenRM), specifically the NV_PBUS_IFR_FMT_FIXEDx definitions in dev_bus.h and the parsing logic in s_romImgFindPciHeader_TU102().

Several QUP lanes have MIRA/MIRB mirror routings that let the same lane be muxed out on alternative GPIOs. On Eliza these were all collapsed under the base function name (e.g. qup1_se6), which prevented boards from selecting the mirror variants.

2026-04-28dt-bindings: clock: amlogic: t7: Add missing mpll3 parent clockJian Hu
The mpll3 clock is one parent clock of the sd_emmc and mipi_isp clocks on the Amlogic T7 SoC, but was missing from t7-peripherals-clkc.yaml bindings. Add the mpll3 clock source to the T7 peripherals clock controller input clock list, so that sd_emmc and mipi_isp can use it. For logical consistency, place the required mpll3 entry before the optional entry. This change breaks the ABI, but while the amlogic,t7-peripherals-clkc bindings have been merged upstream, the corresponding DT has not been merged yet. Thus, no real users or systems are affected.

Qualcomm GX(graphics) is a clock controller which has PLLs, clocks and Power domains (GDSC), but the requirement from the SW driver is to use the GDSC power domain from the clock controller to recover the GPU firmware in case of any failure/hangs. The rest of the resources of the clock controller are being used by the firmware of GPU. This module exposes the GDSC power domains which helps the recovery of Graphics subsystem. Milos can reuse the qcom,kaanapali-gxclkctl.h header due to similarity of the hardware block, and also reuse of the Linux driver.

R-Mobile A1 Document the ZT trace bus and ZTR trace clocks on R-Mobile A1. These clocks supply the coresight tracing modules, PTM, TPIU, ETB and replicator. Without these clocks, coresight tracing can not be operated. While this does change the ABI, it does so by extending the existing clock-output-names, therefore if old software is used with new DT, the coresight tracing parts will likely fail to probe, otherwise if new software is used with an old DT, there is no impact.

2026-04-27misc: Remove old APDS990x driverSvyatoslav Ryhel
The APDS990x driver in misc lacks DeviceTree support, and no mainline pre-DT board files configured this device using apds990x_platform_data. This driver belongs to a legacy group of ambient light sensor drivers in drivers/misc/ that predates the migration to DT and the standard IIO ABI. Since the Avago APDS9900/9901 ALS/Proximity sensor is now supported by the tsl2772 IIO driver and there are no active users in the kernel tree, remove this old implementation.

The Data Ready/FIFO interrupt has a special behavior that inverts the IRQ polarity when devices with FIFO support enter FIFO mode, while using normal polarity for data ready. Document the interrupts property to clarify this special behavior for users.

In the data storage description of a scan element, the first character after the colon can have the values 's' and 'u' to specify signed and unsigned integers, respectively. Add 'f' as an allowed value to specify floating-point numbers formatted according to the IEEE 754 standard.

2026-04-27iio: Replace 'sign' field with union in struct iio_scan_typeFrancesco Lavra
This field is used to differentiate between signed and unsigned integers. A following commit will extend its use in order to add support for non- integer scan elements; therefore, replace it with a union that contains a more generic 'format' field. This union will be dropped when all drivers are changed to use the format field. Opportunistically replace character literals with symbolic constants that represent the set of allowed values for the format field.
