[PATCH 11/21] clk: migrate to SPDX-License-Identifier use

Subject: [PATCH 11/21] clk: migrate to SPDX-License-Identifier use
Date: Mon, 13 Apr 2020 09:51:54 +0200	[thread overview]
Message-ID: <20200413075204.17544-12-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20200413075204.17544-1-a.fatoum@pengutronix.de>

Some of these are a product of source sync with Linux, the other were
done with macro assistance by searching for /later/, deleting license text,
adding appropriate SPDX-License-Identifier and manual post-review.

Devices without a license indicated where assumed GPL-2.0-only according
with the project's license.
