[PATCH 05/15] fsi/fsi-master-gpio: Add "no-gpio-delays" option

2018-05-28 Thread Benjamin Herrenschmidt
This adds support for an optional device-tree property that makes the driver skip all the delays around clocking the GPIOs and set it in the device-tree of common POWER9 based OpenPower platforms. This useful on chips like the AST2500 where the GPIO block is running at a fairly low clock
