[PATCH v8 0/4] gpiolib: speed up GPIO array processing

2018-09-05 Thread Janusz Krzysztofik
The goal is to boost performance of get/set array functions while processing GPIO arrays which represent pins of a signle chip in hardware order. If resulting performance is close to PIO, GPIO API can be used for data I/O without much loss of speed. Created and tested on a low end Amstrad Delta
