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.
Albert Aribaud (4): suen3: remove CONFIG_HARD_I2C and related defines i2c: rename kirkwood_i2c to mvtwsi i2c: rewrite mvtwsi, support orion5x and kirkwood edminiv2: add I2C support using mvtwsi driver
