* mtd: rawnand: Deprecate the ->select_chip() hookBoris Brezillon2018-12-071-1/+1
| | | | | | | | | | | Now that the CS line to be selected is passed to ->exec_op() and stored in chip->cur_cs and after patching all drivers implementing ->exec_op() to stop implementing this method, we can deprecate it by moving it to the nand_legacy structure.

* mtd: rawnand: Move platform_nand_xxx definitions out of rawnand.hBoris Brezillon2018-10-031-2/+1
| | | | | | | | | platform_nand_xxx definitions are just used by the plat_nand driver. Let's move those definitions out of the core/driver-agnostic rawnand.h header. Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
* mtd: rawnand: Deprecate ->chip_delayBoris Brezillon2018-10-031-1/+1
| | | | | | | | | The wait timeouts and delays are directly extracted from the NAND timings and ->chip_delay is only used in legacy path, so let's move it to the nand_legacy struct to make it clear.

* mtd: rawnand: Create a legacy struct and move ->IO_ADDR_{R, W} thereBoris Brezillon2018-10-031-2/+2
| | | | | | | | | | | | | | We regularly have new NAND controller drivers that are making use of fields/hooks that we want to get rid of but can't because of all the legacy drivers that we might break if we do. So, instead of removing those fields/hooks, let's move them to a sub-struct which is clearly documented as deprecated. We start with the ->IO_ADDR_{R,W] fields.

* mtd: rawnand: plat_nand: Pass a nand_chip object to all platform_nand_ctrl hooksBoris Brezillon2018-10-031-5/+52
| | | | | | | | | | | | | | | | | | | | | Let's make the raw NAND API consistent by patching all helpers and hooks to take a nand_chip object instead of an mtd_info one or remove the mtd_info object when both are passed. In order to do that, we first need to update the platform_nand_ctrl hooks to take a nand_chip object instead of an mtd_info. We add temporary plat_nand_xxx() wrappers to the do the mtd -> chip conversion, but those will be dropped when patching nand_chip hooks to take a nand_chip object.
