Subject: [PATCH v3 0/2] Add support for read retry

From: Cheng Ming Lin <chengminglin@...c.com.tw>

When the host ECC fails to correct the data error of NAND device,
there's a special read for data recovery method which can be setup
by the host for the next read. There are several retry levels that
can be attempted until the lost data is recovered or definitely
assumed lost.

For more detailed information, please refer to the link below:

v3:
* If set_read_retry fails, it should return an error

v2:
* Remove fixups
* Remove the function of init_read_retry
