From c4dfa25ab307a277eafa7067cd927fbe4d9be4ba Mon Sep 17 00:00:00 2001 From: Alban Bedel Date: Tue, 13 Nov 2018 15:01:10 +0100 Subject: mtd: add support for reading MTD devices via the nvmem API Allow drivers that use the nvmem API to read data stored on MTD devices. For this the mtd devices are registered as read-only NVMEM providers. We don't support device tree systems for now. Signed-off-by: Alban Bedel [Bartosz: - include linux/nvmem-provider.h - set the name of the nvmem provider - set no_of_node to true in nvmem_config - don't check the return value of nvmem_unregister() - it cannot fail - tweaked the commit message] Signed-off-by: Bartosz Golaszewski Acked-by: Boris Brezillon Signed-off-by: Greg Kroah-Hartman --- include/linux/mtd/mtd.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/linux/mtd') diff --git a/include/linux/mtd/mtd.h b/include/linux/mtd/mtd.h index cd0be91bdefa..545070c2ee64 100644 --- a/include/linux/mtd/mtd.h +++ b/include/linux/mtd/mtd.h @@ -25,6 +25,7 @@ #include #include #include +#include #include @@ -341,6 +342,7 @@ struct mtd_info { struct device dev; int usecount; struct mtd_debug_info dbg; + struct nvmem_device *nvmem; }; int mtd_ooblayout_ecc(struct mtd_info *mtd, int section, -- cgit
