Subject: [PATCH 10/17] clk: sunxi=ng: add support for R329 R-CCU
Date: Mon,  2 Aug 2021 14:22:05 +0800	[thread overview]
Message-ID: <20210802062212.73220-11-icenowy@sipeed.com> (raw)
In-Reply-To: <20210802062212.73220-1-icenowy@sipeed.com>

Allwinner R329 has clock controls in PRCM, like other new Allwinner
SoCs.

Add support for them.

This driver is added before the main CCU because PLLs are controlled by
R-CCU on R329.
