Subject: mtd: mchp23k256: add partitioning support
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2f071ff175ea221710d583222b55f915d90901f0;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mtd: mchp23k256: add partitioning support

Setting the of_node for the mtd device allows the generic mtd code to
setup the partitions.

[Editorial note (Brian): patch still pending on fixing up the "aligned
to eraseblock" partition sanity check, given that this SRAM has no
eraseblocks.]
