Subject: [GIT PULL] i2c for v7.3, part 1
Date: Sat, 15 Aug 2026 12:38:09 +0200 [thread overview]
Message-ID: <aoBAaw7d1A6-a5PJ@zenone.zhora.eu> (raw)
Hi Linus,
here is the first part of the I2C pull request for v7.3. I expect
to send a second part next Saturday, as a few patches still have
dependencies and a few others are left over.
The main changes are support for shared SCL lines in i2c-gpio,
a larger qcom-geni update covering tracing and transfer recovery
and support for R-Car Gen5.
The rest is mostly smaller driver, core and DT binding updates.
Thanks,
Andi

i2c: core: support recovery for single-ended GPIOs (2026-07-29 23:38:13 +0200)
----------------------------------------------------------------
i2c for v7.3
Core and helpers:
- support bus recovery with single-ended GPIOs
- acpi: clean up resource handling
- acpi: force ELAN1300 to 100 kHz
- algo-bit: allow consumers to skip the optional bus test
Drivers:
- use generic bus frequency definitions in nomadik,
octeon-core, microchip-corei2c, k1, davinci and pnx
- i2c-gpio: support multiple buses sharing the same SCL line
- qup: propagate clock enable failures
- spacemit: configure SCL timing and clean up clock handling
- amd-asf: guard against oversized firmware length
qcom-geni:
- add tracepoints for bus setup, interrupts and errors
- use dedicated completion events for abort and reset
- distinguish address and data NACK handling
- cancel transfers before falling back to abort
- simplify runtime PM and resource management
- refactor resource and serial engine initialization
DT bindings:
- convert Altera bindings to DT schema
- convert Axxia bindings to DT schema
New support:
- R-Car Gen5 and R-Car X5H
- Axiado AX3005
- Qualcomm Nord SA8797P
- Qualcomm SA8255p
