Subject: [PATCH 578/697] dts: bcm2712-ds: Restore gpio-direct to gio_aon
|
|
|
|
gpio-direct mode is a modification of the brcmstb GPIO driver that
|
|
makes it play nicely with the userspace pinctrl utility. The mode
|
|
forces the drive to read its state from the hardware each time, rather
|
|
than relying on cached state. Doing so slightly reduces performance,
|
|
but this is not a heavily used code path.
