Subject: [RFC PATCH 7/7] [DO NOT MERGE] clk: sunxi-ng: Add support for T5
Date: Wed, 1 Sep 2021 00:39:51 -0500 [thread overview]
Message-ID: <20210901053951.60952-8-samuel@sholland.org> (raw)
In-Reply-To: <20210901053951.60952-1-samuel@sholland.org>
The T5 RTC is similar to the H616 RTC (no rtc-32k mux, pll-32k as the
second fanout input), except that it adds the ext-osc32k input.
It also isn't a "sun50i" SoC, so it creates a bit of a naming problem...
