SUMMARY:

This patchset improves the driver for the Marvell TWSI interface found
on orion5x and kirkwood SoCs and adds I2C support to the orion5x-based
ED Mini V2 board. The mvtwsi driver is a complete rewrite, 50% shorter
in source code lines, 25% smaller in object size, much simpler and way
faster than the kirkwood_i2c driver it replaces.

PATCH SET:

Patch 1 removes dependencies on kirwkood_i2c from suen3, the only
board that mentioned it. Patch 2 renames the driver from kirkwood_i2c
to mvtwsi. Patch 3 replaces the old code with the new one. Patch 4
adds support for I2C in orion5x-based ED Mini V2.

TESTS:

This driver has been tested on an ED Mini V2 with basic u-boot i2c
commands, on an 5C372a RTC and an HT24LC08 1 KB eeprom (read+write).

HISTORY:

V1: Initial submission as an addition rather than a replacement.

V2: Fixed copyright line.
Made mvtwsi a replacement for kirkwood_i2c.
Made patches checkpatch-clean: 0 errors, 0 warnings.
Various cosmetic changes.
Removed useless i2c_end() function.

V3: Reduced line lengths below 78 characters.
Removed blank line after function description block comment.

i2c: rename kirkwood_i2c to mvtwsi
