Subject: [PATCH 6/6] clk: ingenic: Add support for the JZ4760
Date: Sun, 7 Mar 2021 14:17:59 +0000 [thread overview]
Message-ID: <20210307141759.30426-7-paul@crapouillou.net> (raw)
In-Reply-To: <20210307141759.30426-1-paul@crapouillou.net>
Add the CGU code and the compatible string to the TCU driver to support
the JZ4760 SoC.
