Re: [PATCH v3 0/2] Changes in the internal raw NAND API

> 
> 1/ Rename struct nand_hw_control -> struct nand_controller which is
>    much more meaningful.
> 2/ Rename the function initializing the above structure
>    nand_hw_control_init() -> nand_controller_init().
> 3/ Rename the dummy controller implementation in the nand_chip structure
>    hwcontrol -> dummy_controller.
> 3/ Create a nand_controller_ops structure which will be embedded in the
>    nand_controller structure. These operations are:
>    int (*attach_chip)(struct nand_chip *) and
>    void (*detach_chip)(struct nand_chip *).

> If we agree on this, I could merge them first and then send the bunch of

> * Reworded the nand_controller structure documentation as suggested.

> * Removed the initialization of controller->ops() in

> * Also mentioned that ->detach_chip() will be called from

> Changes since v1 (RFC):
> =======================
> * Added Acked-by tags from Boris.
> * Updated the commit logs as commented.
> * Squashed the 2 patches about nand_hw_control and
>   nand_init_hw_control().
> * Also added the rename of hwcontrol in patch 1.
> * Added helpers to 1/ check the controller operations are present and
>   2/ ->attach_chip() or ->detach_chip() is available, as suggested by
>   Boris.
