Subject: [PATCH 15/15] misc: atmel_tclib: Do not probe already used TCBs
Date: Thu, 9 May 2019 13:10:48 +0200 [thread overview]
Message-ID: <20190509111048.11151-15-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <20190509111048.11151-1-daniel.lezcano@linaro.org>
From: Alexandre Belloni <alexandre.belloni@bootlin.com>
The TCBs that have children are using the proper DT bindings and don't need
to be handled by tclib.
