Sonic Zhang 28a377c79a i2c:i2c-bfin-twi: TWI fails to restart next transfer in high system load. ... Current driver was developed based on BF537 0.2 HRM. In high system load, BUFRDERR error interrupt may be raised if XMTSERV interrupt of last TX byte is not served in time (set RSTART bit), which breaks restart tranfer as expected. "Buffer Read Error (BUFRDERR)" description in Blackfin HRM only applys to BF537 rev. < 0.3. In later rev. and later announced Blackfin chips, such as BF527 and BF548, a new TWI master feature "Clock Stretching" is added into the TWI controller, BUFRDERR interrupt is not triggered after TX FIFO is empty. This patch sets RSTART bit at the beginning of the first transfer. The SCL and SDA is hold till XMTSERV interrupt of last TX byte is served. Restart transfer is not broken in high system load.
