mtd: rawnand: Add NV-DDR timings

2022-08-21T13:16:16Z

[ Upstream commit 1666b815ad1a5b6373e950da5002ac46521a9b28 ] Create the relevant ONFI NV-DDR timings structure and fill it with default values from the ONFI specification. Add the relevant structure entries and helpers. Signed-off-by: Miquel Raynal Link: https://lore.kernel.org/linux-mtd/20210505213750.257417-9-miquel.raynal@bootlin.com Signed-off-by: Sasha Levin

mtd: rawnand: Add a helper to clarify the interface configuration

2022-08-21T13:16:16Z

[ Upstream commit 961965c45c706175b24227868b1c12d72775e446 ] Name it nand_interface_is_sdr() which will make even more sense when nand_interface_is_nvddr() will be introduced. Use it when relevant.

mtd: rawnand: protect access to rawnand devices while in suspend

2022-04-08T12:39:51Z

commit 8cba323437a49a45756d661f500b324fc2d486fe upstream. Prevent rawnand access while in a suspended state. Commit 013e6292aaf5 ("mtd: rawnand: Simplify the locking") allows the rawnand layer to return errors rather than waiting in a blocking wait. Tested on a iMX6ULL.

mtd: rawnand: Use the NAND framework user_conf object for ECC flags

2020-09-30T14:44:15Z

Instead of storing the ECC flags in chip->ecc.options, use nanddev->ecc.user_conf.flags. There is currently only one to save: NAND_ECC_MAXIMIZE. Signed-off-by: Miquel Raynal Link: https://lore.kernel.org/linux-mtd/20200827085208.16276-21-miquel.raynal@bootlin.com

mtd: rawnand: Use the ECC framework user input parsing bits

2020-09-30T14:44:15Z

Many helpers are generic to all NAND chips, they should not be raw-NAND specific, so use the generic ones. To avoid moving all the raw NAND core "history" into the generic NAND layer, we keep a part of this parsing in the raw NAND core to ensure backward compatibility.

mtd: rawnand: Use the new ECC engine type enumeration

2020-09-28T13:59:42Z

Mechanical switch from the legacy "mode" enumeration to the new "engine type" enumeration in drivers and board files. The device tree parsing is also updated to return the new enumeration from the old strings.

mtd: rawnand: Separate the ECC engine type and the ECC byte placement

2020-09-28T13:56:34Z

The use of "syndrome" placement should not be encoded in the ECC engine mode/type. Create a "placement" field in NAND chip and change all occurrences of the NAND_ECC_HW_SYNDROME enumeration to be just NAND_ECC_HW and possibly a placement entry like NAND_ECC_PLACEMENT_INTERLEAVED.
