GIO_PA_OE found in arch/cris/arch-v32/mach-fs/Kconfig

The configuration item CONFIG_ETRAX_DEF_GIO_PA_OE:

• prompt: GIO_PA_OE
• type: hex
• depends on: CONFIG_ETRAX_ARCH_V32
• defined in arch/cris/arch-v32/mach-fs/Kconfig
• found in Linux kernels: 2.6.25–2.6.39, 3.0–3.19, 4.0–4.16

Configures the direction of general port A bits. 1 is out, 0 is in. This is often totally different depending on the product used. There are some guidelines though - if you know that only LED's are connected to port PA, then they are usually connected to bits 2-4 and you can therefore use 1c. On other boards which don't have the LED's at the general ports, these bits are used for all kinds of stuff. If you don't know what to use, it is always safe to put all as inputs, although floating inputs isn't good.
