Subject: [PATCH v3 9/9] misc: atmel_tclib: do not probe already used TCBs
Date: Fri, 26 Apr 2019 23:47:18 +0200 [thread overview]
Message-ID: <20190426214718.13470-10-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20190426214718.13470-1-alexandre.belloni@bootlin.com>
The TCBs that have children are using the proper DT bindings and don't need
to be handled by tclib.
Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
