tegra: usb: Fix device enumeration problem of USB1

2012-07-09T20:44:34+00:00

A known hardware issue of USB1 port where bit 1 (connect status
change) of PORTSC register will be set after issuing Port Reset
(like "usb reset" in u-boot command line).
This will be treated as an error and stops later device enumeration.

Therefore we clear that bit after Port Reset in order to proceed
later device enumeration.

i2c: designware_i2c.c: Add support for the "i2c probe" command

2012-07-07T12:07:43+00:00

i2c_probe() is changed to reinit the i2c bus upon read failure.
This is naturally the case upon i2c bus probing.

Also, some printf messages upon read failure are removed. As they
would interfere with the "i2c probe" command.

Additionally, i2c_set_bus_speed() now returns 0, so that the
"i2c speed" command can be used.

rtc/m41t62: Add support for M41T82 with HT (Halt Update)

2012-07-07T12:07:43+00:00

Add support for the M41T82 RTC to the m41t62 driver. The only
difference that needs to be handled by this driver, is to
clear the HT (Halt Update) bit upon reset. This bit is not
used on the M41T62, so its save to clear this bit always.

The M41T82 support will be used by the X600 (SPEAr600)
board support.
