[ARM] 3325/2: GPIO function to control multi-drive (open collector) capability
Patch from Andrew Victor This patch adds the at91_set_multi_drive() function to enable/disable the multi-drive (open collector) pin capability on the AT91RM9200 processor. This is necessary to fix the UDC (USB Gadget) driver for the AT91RM9200 board as it will not allow the board reset line to be pulled low if the pullup is not driven as an open collector output as the boards are wired to the USB connector on both the DK/EK. This version of the patch updates it to 2.6.16-rc4. Orignal patch by Jeff Warren. Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
