Subject: [Patch v3 10/13] media: am437x-vpfe: TRY_FMT ioctl is not really trying anything
Date: Fri, 20 Sep 2019 12:05:51 -0500 [thread overview]
Message-ID: <20190920170554.29666-11-bparrot@ti.com> (raw)
In-Reply-To: <20190920170554.29666-1-bparrot@ti.com>
The try_fmt was not actually trying out the provided format
but merely returning the current format basically like get_fmt.
In addition set_fmt should first invoked try_fmt to validate the
given format before applying it to the hardware.
To fix all of these the whole get/try/set ioctl functions had to
be reworked.
When calculating the bytesperline/stride and sizeimage format
member we don't need to locally store the current value of
bytesperpixel as it can easily get derived dynamically.
