Subject: [PATCH v2 12/15] clk: sunxi-ng: a64: Add min and max rate for PLL_MIPI
Date: Tue, 23 Oct 2018 21:20:32 +0530	[thread overview]
Message-ID: <20181023155035.9101-13-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20181023155035.9101-1-jagan@amarulasolutions.com>

A64 manual say PLL_MIPI rates are 500MHz to 1.4GHz, but
using minimum 500MHz can't release the clock and which
is not working.

So use working minimum rate as 300MHz which is tested on
Bananapi DSI panel.
