Subject: [PATCH RFT 2/7] media: hantro: Fix overfill bottom register field name
Date: Fri, 24 Dec 2021 16:42:43 +0800 [thread overview]
Message-ID: <20211224084248.3070568-3-wenst@chromium.org> (raw)
In-Reply-To: <20211224084248.3070568-1-wenst@chromium.org>
The Hantro H1 hardware can crop off pixels from the right and bottom of
the source frame. These are controlled with the H1_REG_IN_IMG_CTRL_OVRFLB
and H1_REG_IN_IMG_CTRL_OVRFLR in the H1_REG_IN_IMG_CTRL register.
The ChromeOS kernel driver that this was based on incorrectly added the
_D4 suffix H1_REG_IN_IMG_CTRL_OVRFLB. This field crops the bottom of the
input frame, and the number is _not_ divided by 4. [1]
Correct the name to avoid confusion when crop support with the selection
API is added.

Fixes: 775fec69008d ("media: add Rockchip VPU JPEG encoder driver")
Fixes: a29add8c9bb2 ("media: rockchip/vpu: rename from rockchip to hantro")
