<The_Coolest> Hey guys, I have a few questions, hope you can help me out.
<The_Coolest> Do gpio_direction_output and gpio_direction_input functions have a big overhead? I have a feeling that it does, but I'm not sure.

<The_Coolest> And if it does, what would be a good way to get around it. Basically I have my own I2C and SPI bit-bang code in my driver, and I'd like to make that more efficient.
<The_Coolest> Is MMIO a good solution? I assume that it is, but I couldn't really figure out how to do it, if you can point me in the right direction, I'd appreciate it.
