Subject: cm-t35: fix Ethernet reset timing
X-Git-Tag: v2012.04-rc2~1^2~28

cm-t35: fix Ethernet reset timing

The reset_net_chip() function has wrong timings for the reset pulse.

This appeared to work until:
0607e2b (ARMV7: OMAP: Write more than 1 byte at a time in i2c_write)

Fix the Ethernet support by introducing right timings.
