Subject: [PATCH v2] media: staging: rkisp1: set more precise size errors in debugfs
Date: Fri, 29 May 2020 16:03:51 +0200 [thread overview]
Message-ID: <20200529140351.18632-1-dafna.hirschfeld@collabora.com> (raw)
When a size error is signaled, it is possible to read a register
to see where the error comes from. So, in debugfs the general
error 'pic_size_err' can be replaced with 3 more precise errors.
