Hi Maxime,

This series adds some more alternate pin configurations which were missing
upstream, the DT config for SSC12, and also a DT node for the 24c256 eeprom.

regards,

Peter.

Peter Griffin (4):
  ARM: DT: STiH407: Add UART RTS/CTS pin configuration
  ARM: DT: STiH407: Add i2c12 pin definition
  ARM: DT: STiH407: Add node for i2c12 controller
  ARM: STi: DT: STiH407: Add DT node for eeprom

More information is required in the commit message.

What do we use the EEPROM for?  What information is contained within?
What stops working if we don't support it?  What starts working if we
