[PATCH v2 0/3] drm/xe/i2c: alerts and controller enabling modifications

[Heikki Krogerus]

Hi,

Changed since v1:
- Global header for the DesignWare I2C registers which meant a bit of
  patch refactoring.
- Selecting CONFIG_SMBUS in CONFIG_XE and handling smbus in xe_i2c.c instead of
  separate file.
- Storing the alert device to the client array and providing enum for the
  clients.
- Allowing other fields in the IC_ENABLE register to be updated except the
  Enable bit.
- Can't sleep in xe_i2c_disable() so using udelay().

v1: https://lore.kernel.org/lkml/20260622114759.3464047-1-heikki.krogerus@xxxxxxxxxxxxxxx/

This includes support for the SMBus alerts, and special handling for the
IC_ENABLE register.

Thanks,
