Thomas Cort 228e84ad2a i2c: general clean-up ... Implement changes based on Kees comments on the code review: http://gerrit-minix.few.vu.nl/#/c/676/ Changes: - use spin API instead of micro_delay() for busy-wait loops. - use read16/write16/set16 from mmio.h to access I2C registers. - reduce the timeout for soft reset. - in read/write, don't mix variable declaration and initialization. - after transfer, wait for access ready instead of blindly delaying. - rename constants am335x, dm37xx to AM335X_I2C_BUS, DM37XX_I2C_BUS. - rename ADDRESS_MASK to MAX_I2C_SA_MASK for clairity. - rename omap_i2c_claim_bus() to omap_i2c_bus_is_free().
