Subject: [PATCH 2/2] media: i2c: adv748x: Remove PAGE_WAIT
Date: Fri, 11 Jan 2019 17:41:41 +0000 [thread overview]
Message-ID: <20190111174141.12594-3-kieran.bingham+renesas@ideasonboard.com> (raw)
In-Reply-To: <20190111174141.12594-1-kieran.bingham+renesas@ideasonboard.com>
The ADV748X_PAGE_WAIT is a fake page to insert arbitrary delays in the
register tables.
Its only usage was removed, so we can remove the handling and simplify
the code.
