[PATCH 0/4] STi DT updates

[Peter Griffin]

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.

  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

Re: [PATCH 4/4] ARM: STi: DT: STiH407: Add DT node for eeprom

[Lee Jones]

More information is required in the commit message.

What stops working if we don't support it?  What starts working if we
