Subject: [PATCH v2 9/9] misc: atmel_tclib: do not probe already used TCBs
Date: Mon, 15 Apr 2019 17:08:56 +0200 [thread overview]
Message-ID: <20190415150856.9384-10-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20190415150856.9384-1-alexandre.belloni@bootlin.com>
The TCBs that have children are using the proper DT bindings and don't need
to be handled by tclib.
