Subject: [RESEND PATCH v4 20/21] staging: media: tegra-video: add H/V flip controls
Date: Thu, 9 Mar 2023 15:43:19 +0100 [thread overview]
Message-ID: <20230309144320.2937553-21-luca.ceresoli@bootlin.com> (raw)
In-Reply-To: <20230309144320.2937553-1-luca.ceresoli@bootlin.com>
Tegra20 can do horizontal and vertical image flip, but Tegra210 cannot
(either the hardware, or this driver).
In preparation to adding Tegra20 support, add a flag in struct tegra_vi_soc
so the generic vi.c code knows whether the flip controls should be added or
not.
Also provide a generic implementation that simply sets two flags in the
channel struct. The Tegra20 implementation will enable flipping at stream
start based on those flags.
