Subject: [PATCH 0/3] usb: meson: fix shared reset control use
Date: Fri, 13 Nov 2020 01:05:05 +0100 [thread overview]
Message-ID: <20201113000508.14702-1-aouledameur@baylibre.com> (raw)
This patchset fixes a usb suspend warning seen on the libretech-cc by
using reset_control_rearm() call of the reset framework API.
This call allows a reset consummer to release the reset line even when
just triggered so that it may be triggered again by other reset
consummers.
reset_control_(de)assert() calls are called, in some meson usb drivers,
on a shared reset line when reset_control_reset has been used. This is not
allowed by the reset framework.
Finally the meson usb drivers are updated to use this new call, which
solves the suspend issue addressed by the previous reverted
commit 7a410953d1fb ("usb: dwc3: meson-g12a: fix shared reset control
use").
Important:
Please DO NOT merge before this patch [0] is merged, it adds
reset_control_rearm() call to the reset framework API.
