Hi Linus,
here is the first part of the I2C pull request for v7.4.
The main changes are the new Novatek NT72676 driver, the qcom-cci
clock and timing updates and a collection of smaller driver, core
and DT binding improvements.
Between family commitments and conferences, a few patches didn't
make it into this round. If the merge window gets an extra third
week, I'll use it to catch up with some of them.
A second part will definitely follow, probably on Sunday. I
already have some patches queued up, a few waiting for
dependencies to be fixed and others simple enough to be safely
included.
Meanwhile, I wish you great holidays, both under and above the
water.
Andi

i2c: imx-lpi2c: remove dmaengine_desc_free() (2026-10-13 15:55:40 +0200)
----------------------------------------------------------------
i2c for v7.4, part 1
A mix of new hardware support, driver improvements and smaller
core, DT binding and documentation cleanups.
Core and helpers:
- acpi: run ASUS and Dell touchpads at 100 kHz to avoid lag
- core: return bool from check_functionality() and update users
- smbus: limit block reads to the caller's buffer size
- acpi: mark I2C transfer buffers as DMA-safe
Drivers:
- qcom-geni: several firmware node and runtime PM improvements
- qcom-cci: several patches rework clock selection and timings
- qcom-cci: enable SCL clock stretching
- imx-lpi2c: fix DMA mapping device selection and cleanup
- designware: tune RX FIFO thresholds to reduce interrupts
- i801: respect SPD write protection when probing DDR5 modules
- bcm2835: fully initialize clock configuration data
Generic cleanups:
- mux: simplify channel lookup and firmware node handling
- core, busses: tidy up ACPI device ID tables
- docs: clarify adapter lookup and fix a client driver example
- xlnx: update maintainer for Xilinx IIC bindings
- ljca: remove redundant adapter deletion
New support and DT bindings:
- add DW compatibles for Synaptics SL2610 and UltraRISC DP1000
- allow six DMA channels for R-Car Gen5
- add Allwinner A733 compatible to mv64xxx bindings
- add support for Novatek NT72676 (new driver)
