If the bus is blocked because of a previously interrupted
transfer, up to eleven clocks are generated on the I2CSCL
line to complete the transfer and to free the bus.
With this fix pin I2CSCL (PG6) is really configured as GPIO
so the clock pulses are really generated.
Patch by Martin Krause, 04 Apr 2006
A new, Windows compatible init sequence was also backported from Linux 2.6,
but disabled with #undef NEW_INIT_SEQ as it wouldn't change the behaviour
of the memopry sticks we tested. Maybe it's not relevant for mass storage
devices. For recerence, see file common/usb.c, function usb_new_device(),
section #ifdef NEW_INIT_SEQ.
- Use i.MX watchdog timer for reset_cpu()
- Move reset_cpu() out of cpu/arm920t/start.S into the SoC specific
subdirectories cpu/arm920t/imx/ and cpu/arm920t/s3c24x0/
(now in interupts.c)
- Introducing the concept of SoCs "./cpu/$(CPU)/$(SOC)"
- creating subdirs for SoCs ./cpu/arm920t/imx and ./cpu/arm920t/s3c24x0
- moving SoC specific code out of cpu/arm920t/ into cpu/arm920t/$(SOC)/
- moving drivers/s3c24x0_i2c.c and drivers/serial_imx.c out of drivers/
into cpu/arm920t/$(SOC)/
