Subject: [PATCH v2 2/6] media: adv748x: Rename reset procedures
Date: Sun,  6 Jan 2019 16:54:09 +0100	[thread overview]
Message-ID: <20190106155413.30666-3-jacopo+renesas@jmondi.org> (raw)
In-Reply-To: <20190106155413.30666-1-jacopo+renesas@jmondi.org>

Rename the chip reset procedure as they configure the CP (HDMI) and SD
(AFE) cores.
