[PATCH] spi: spi-sun6i: enable autosuspend feature

2020-10-16 Thread Alexander Kochetkov
If SPI is used for periodic polling any sensor, significant delays sometimes appear. Switching on module clocks during resume lead to delays. Enabling autosuspend mode causes the controller to not suspend between SPI transfers and the delays disappear. Signed-off-by: Alexander Kochetkov ---
