Subject: [PATCH 2/4] regulator: core: notify regulator enable with the voltage value
Date: Mon, 16 Aug 2021 11:20:01 +0800	[thread overview]
Message-ID: <20210816032003.1162779-3-jay.xu@rock-chips.com> (raw)
In-Reply-To: <20210816032003.1162779-1-jay.xu@rock-chips.com>

Get the voltage of regulator and then pass it as the parameter of
notify, the driver could take it.

The origin parameter for notify is NULL, so this patch do nothing effect
to other driver who not care about the voltage value.
