[PATCH v2 0/2] i2c: Add new driver for Renesas RZ/V2M controller

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

The Renesas RZ/V2M SoC (r9a09g011) has a new i2c controller. This series
add the driver. One annoying problem is that the SoC uses a single reset
line for two i2c controllers, and unfortunately one of the controllers
is managed by some firmware, not by Linux. Therefore, the driver just
deasserts the reset.

v2:
  dt-binding:
  - Use an enum and set the default for clock-frequency
  - Add resets property
  driver:
  - Use the new NOIRQ_SYSTEM_SLEEP_PM_OPS() as suggested by Arnd
  - Lots of small fixes based on Geert's review
