The following patches are required to fix the existing driver to support i2c on pistachio. Tested on Pistachio bub using an Adafruit I2C Non-Volatile FRAM Breakout (256Kbit / 32KByte) eeprom. Used i2c buildroot tools to test the eeprom and the other i2c blocks. Also used dd commands to copy data to and then to dump data from the eeprom. i2ctransfer was used to test repeated starts and verified using a scope. Changes from v1: removed v1 5/8: i2c-img-scb-reset-interrupts-in-img_i2c_soft_reset removed v1 7/8: i2c-img-scb-improve-transaction-complete-handle 4/7: extra space removed 5/7: line_status used instead of i2c->line_status 6/7: reworked v1 7/8 and added as new patch 7/7: reworked, limit bitrate to maximum supported 12 digit hash id used.
