| mtd: nand: denali_dt: enable HW_ECC_FIXUP for Altera SOCFPGA variant
|
| There are various customizable parameters, so several variants for
| this IP.  A generic compatible like "denali,denali-nand-dt" is
| useless.  Moreover, there are multiple things wrong with this string.
|  (Refer to Rob's comment [1])
|
| The "denali,denali-nand-dt" was added by Altera for the SOCFPGA port.
| Replace it with a more specific string "altr,socfpga-denali-nand".
| There are no users (in upstream) of the old compatible string.
|
| The Denali IP on SOCFPGA incorporates the hardware ECC fixup engine.
| So, this capability should be associated with the compatible.
