[PATCH v3 00/14] mps2: Add few more peripherals

[Philippe Mathieu-Daudé]

Few patches while playing with Zephyr on the MPS2:

- clean 'versatile_i2c' a bit,
- describe it as 'ARM SBCon two-wire serial bus interface'
  which is common on the ARM documentation,
- add watchdog
- added fpgaio with correct prescale clk
- added i2c and spi
- added gpio/i2s as unimp
- dropped the fpgaio push-button patch

Since v2:
- added missing Kconfig select
Since v1:
- addressed Peter review comments
