Date: Sun, 24 Apr 2022 13:59:59 +0800 From: Icenowy Zheng <uwu@...nowy.me> To: Chen-Yu Tsai <wens@...e.org>, Jernej Skrabec <jernej.skrabec@...il.com>, Samuel Holland <samuel@...lland.org> Cc: linux-clk@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-sunxi@...ts.linux.dev, linux-kernel@...r.kernel.org, Icenowy Zheng <uwu@...nowy.me> Subject: [PATCH] clk: sunxi-ng: ccu-sun6i-rtc: set rtc-32k to critical RTC itself is the one and only consumer of rtc-32k clock. As the rtc should be always running, set rtc-32k clock to critical, to prevent it from being gated by the kernel.
