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").
changes since v1: [1]
* Moved reset_control_rearm after clk_disable_unprepare to clean things up
in reverse order of initialization for phy: amlogic: meson drivers
IMPORTANT:
This patchset depends on this patch [2], it adds reset_control_rearm() call
to the reset framework API, it has been approved by the maintainer, and
will be applied to reset/next
There is currently an immutable branch with it [3]
