Subject: [PATCH v5 03/44] clk: davinci: Add platform information for TI DA830 PLL
Date: Sun, 7 Jan 2018 20:17:02 -0600 [thread overview]
Message-ID: <1515377863-20358-4-git-send-email-david@lechnology.com> (raw)
In-Reply-To: <1515377863-20358-1-git-send-email-david@lechnology.com>
This adds platform-specific declarations for the PLL clocks on TI DA830/
OMAP-L137/AM17XX SoCs.
