* mtd: rawnand: Deprecate the dummy_controller fieldBoris Brezillon2018-12-071-1/+1
| | | | | | | | | | We try to force NAND controller drivers to properly separate the NAND controller object from the NAND chip one, so let's deprecate the dummy controller object embedded in nand_chip to encourage them to create their own instance.

* 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: 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.

| | | | | | | | | Commit c120e75e0e7d ("mtd: nand: use read_oob() instead of cmdfunc() for bad block check") removed this only user of the ->read_word() method but kept the hook in place.

* mtd: rawnand: hisi504: convert driver to nand_scan()Miquel Raynal2018-07-311-34/+44
| | | | | | | | | | | Two helpers have been added to the core to do all kind of controller side configuration/initialization between the detection phase and the final NAND scan. Implement these hooks so that we can convert the driver to just use nand_scan() instead of the nand_scan_ident() + nand_scan_tail() pair.

* mtd: rawnand: hisi504: fix the probe function error pathMiquel Raynal2018-04-291-1/+1
| | | | | | | | | An error after nand_scan_tail() should trigger a nand_cleanup() and not a nand_release(). The latter doing an mtd_device_unregister() which is not needed if mtd_device_register() failed.

* mtd: rawnand: rename SET/GET FEATURES related functionsMiquel Raynal2018-03-201-2/+2
| | | | | | | | | | SET/GET FEATURES are flagged ONFI-compliant because of their name. This is not accurate as non-ONFI NAND chips support it and use it. Rename the hooks and helpers to remove the "onfi" prefix. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com>
* mtd: nand: move raw NAND related code to the raw/ subdirBoris Brezillon2018-02-161-0/+896
As part of the process of sharing more code between different NAND based devices, we need to move all raw NAND related code to the raw/ subdirectory. Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com>
