Subject: [PATCH v4 05/10] firmware: import fpga-mgr.h from linux
Date: Wed, 16 Jun 2021 08:32:41 +0200
Message-ID: <20210616063246.14900-5-s.trumtrar@pengutronix.de> (raw)
In-Reply-To: <20210616063246.14900-1-s.trumtrar@pengutronix.de>

Instead of defining the fpga-mgr structure in the socfpga driver, import
the fpga-mgr.h file from linux v4.13.
