The Mellanox BlueField is a System-on-Chip (SoC) that combines Arm cores and ConnectX network adapter technology intended to accelerate storage network solutions. The Mellanox BlueField incorporates various I2C devices that are accessed using SMBus protocol, a variant of the I2C protocol. On storage controllers, the BlueField SoC is connected to a management controller board, e.g., BMC via an I2C bus. An I2C driver running on the Arm side is needed to manage the hardware I2C controllers. The driver enables a master function to transfer data back and forth from/to I2C devices, such as EEPROM parts and implements a slave function to handle the BMC controller requests. v6->v7: - Fixing kernel coding style issues as suggested by Mellanox internal code reviewers. - Updating the dependency expression in Kconfig. - Fixing various device driver bugs. - Adding an entry to MAINTAINERS file. v5->v6: - Fixing kernel coding style issues detected using '--strict' flag. - Updating the device binding documentation to add support for BlueField-2 SoCs. v4->v5: - Fixing device driver bug. v3->v4: - Review of the device binding documentation to fix format issue and miscellaneous cleanup. v2->v3: - Various device driver changes and bug fixes. - Updating the device property in the device binding documentation and file format review. v1->v2: - Various device driver changes and bug fixes. - Cleanup of the device binding documentation.
