Subject: [PATCH 56/91] mtd: add get/set of_node/flash_node helpers
|
|
|
|
We are going to begin using the mtd->dev.of_node field for MTD device
|
|
nodes, so let's add helpers for it. Also, we'll be making some
|
|
conversions on spi_nor (and nand_chip eventually) too, so get that ready
|
|
with their own helpers.
