Subject: [BISECTED REGRESSION] OMAP1 GPIO breakage

Hi,

It seems GPIOs on OMAP1 boards are somewhat broken after:

commit 92bf78b33b0b463b00c6b0203b49aea845daecc8

    gpio: omap: use dynamic allocation of base

E.g. on OSK1 the ethernet IRQ cannot (omap_gpio.0) no longer be requested:

[    0.277252] Error requesting gpio 0 for smc91x irq

Also the tps65010 (still using static allocation) will now conflict:

[    0.400726] gpio gpiochip5: Static allocation of GPIO base is deprecated, use dynamic allocation.
[    0.400848] gpio gpiochip5: (tps65010): GPIO integer space overlap, cannot add chip
[    0.400970] gpiochip_add_data_with_key: GPIOs 208..214 (tps65010) failed to register, -16
[    0.401092] tps65010 i2c-tps65010: can't add gpiochip, err -16

I think this change should be reverted until the board files and other
gpiochips are fixed accordingly.
