Hi,
This patchset does the following for the SoCFPGA platform:
- Adds a DM reset manager driver - Make the SoCFPGA platform use the DM I2C driver - Adds i2c aliases and enable i2c for de0_nano_soc platform - Adds a reset manager call to the i2c designware driver to look up any reset properties in the i2c dts node, and deassert the reset the IP if found. - Adds CONFIG_DM_RESET to all the SoCFPGA defconfigs
For this patchset, I'm only enabling the i2c in the DTS for the Terasic DE-0 Atlas board. I'll look to enable the other boards in the near future.
