Subject: [PATCH 10/22] mtd: rawnand: Add an indirection on onfi_fill_interface_config()
Date: Wed,  5 May 2021 23:37:38 +0200	[thread overview]
Message-ID: <20210505213750.257417-11-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20210505213750.257417-1-miquel.raynal@bootlin.com>

This helper actually fills the interface configuration with SDR data.
As part of the work to bring NV-DDR support, let's rename this helper
onfi_fill_sdr_interface_config() and add a generic indirection to it.

There are no functional changes here, but this will simplify a next
change which adds onfi_fill_nvddr_interface_config() support.
