Subject: [RESEND PATCH] memory: atmel-ebi: move NUM_CS definition inside EBI driver
Date: Fri, 6 Sep 2019 15:06:41 +0000 [thread overview]
Message-ID: <20190906150632.19039-1-tudor.ambarus@microchip.com> (raw)
From: Tudor Ambarus <tudor.ambarus@microchip.com>
The total number of EBI CS lines is described by the EBI controller
and not by the Matrix. Move the definition for the number of CS
inside EBI driver.
Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com>
