PCIe reset signals are active low, and our GPIO for this is directly connected to the PCIe reset. However, as the PCIe driver was not using the flag, the specification of '0' flags (which means active high) had not been noticed. Correct this oversight, and switch to using the GPIO flag definitions instead. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
