Subject: [PATCH 3/4] regulator: core: add pre-enable event notify to regulator
Date: Mon, 16 Aug 2021 11:20:02 +0800	[thread overview]
Message-ID: <20210816032003.1162779-4-jay.xu@rock-chips.com> (raw)
In-Reply-To: <20210816032003.1162779-1-jay.xu@rock-chips.com>

Notify the event about regulator to be enabled to driver.

The IO-DOMAIN driver on Rockchip SoCs will take this event and then to
configure the io-domain mode before regualtor_enable.
