Hi,
we need to wait more time for getting USB hub out of reset to be
able to do
initialiation over i2c that's why use gpio-delay driver instead of
changing
waiting time in usb hub driver. Waiting time depends on gpio wiring
on the
board which is in some of our case going via SLG programmable device.
Can you not use some regulator or make the reset assert/deassert
time configurable via DT property ?
Sorry not following. delay is configurable via DT now - the patch 3/3
for example.
3/3 never arrived in my mailbox, I think I was CCed only on 0 and 2 .
This avoid a need to change usb5744 driver to wait longer time which
is what we discussed in past.
If the delay is configurable via DT, why would the driver have to be
changed ?
Delay is configurable via DT for the GPIO delay device. The delay is NOT
configurable via DT for the USB onboard hub device. Because of the
latter, the former is added as GPIO controller for adding delay to the
latter driver's reset line.
Oh, I see, thank you for the clarification.
