[PATCH 08/12] mtd: nand: lpc32xx: rely on generic DT parsing done in nand_scan_ident()

From: Boris Brezillon
Date: Fri Apr 01 2016 - 08:56:36 EST


The core now takes care of parsing generic DT properties in
nand_scan_ident() when nand_set_flash_node() has been called.
Rely on this initialization instead of calling of_get_nand_xxx()
manually.
