Subject: [PATCH 16/30] media: atmel: atmel-isc: add his_entry to register offsets
Date: Thu, 1 Apr 2021 14:27:09 +0300 [thread overview]
Message-ID: <20210401112723.189107-17-eugen.hristev@microchip.com> (raw)
In-Reply-To: <20210401112723.189107-1-eugen.hristev@microchip.com>
Add his_entry to the reg offsets struct.
This will allow different products to have a different reg offset for this
particular module.
