Subject: [PATCH v3 03/11] clk: tegra: dfll registration for multiple SoCs
Date: Tue, 6 Feb 2018 18:34:04 +0200 [thread overview]
Message-ID: <1517934852-23255-4-git-send-email-pdeschrijver@nvidia.com> (raw)
In-Reply-To: <1517934852-23255-1-git-send-email-pdeschrijver-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>
In a future patch, support for the DFLL in Tegra210 will be introduced.
This requires support for more than 1 set of CVB and CPU max frequency
tables.
