[ARM] 4373/1: i.MX/MX1 GPIO support implementation
Support for generic input output for MX1 family. The implementation prevents allocation of one pin by two users, but does not store pointer to the user description permanently, because this solution would have bigger memory overhead. The simple way to integrate code with per BSP pins setup and allocation is required else all GPIO registration checking is useless. The function imx_gpio_setup_multiple_pins() can be used for this purpose in future. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
