Subject: [PATCH 1/2] dt-bindings: gpio: rockchip: add clock-names
Date: Thu, 1 Sep 2022 09:29:40 +0800 [thread overview]
Message-ID: <20220901012944.2634398-2-jay.xu@rock-chips.com> (raw)
In-Reply-To: <20220901012944.2634398-1-jay.xu@rock-chips.com>
Add 'clock-names' to the gpio dt node. so the driver could get clocks by
a const char id, this patch names the clock-names as
- 'bus': the apb clock for cpu to access the gpio controller
- 'db': the debounce clock for cpu to set debounce clock rate
Since the old dt nodes may have no clock-names, this patch not make them
as part of 'required properties'.
