This patch optimizes the gpio data register handling for gpio_set_value(). Instead of using the good old spinlock-plus-read-modify-write strategy we now use a shadow register and atomic operations. This improves the bitbanging mmc performance on Migo-R from 26 Kbytes/s to 40 Kbytes/s. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org> |
