Subject: [PATCH 4/4] spi: atmel-quadspi: Move common code outside of if else
Date: Mon, 7 Dec 2020 15:59:59 +0200 [thread overview]
Message-ID: <20201207135959.154124-5-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20201207135959.154124-1-tudor.ambarus@microchip.com>
QSPI_IFR is set as the last QSPI Instruction Frame register
regardless of the sama5d2 or sam9x60 version of the IP. Move
the writing of QSPI_IFR outside of the IP specific code.
