Subject: [PATCH 00/11] add support for sam9x60 nand controller

From: Tudor Ambarus <tudor.ambarus@...rochip.com>

The sam9x60 board defines the CCFG_EBICSA register under SFR,
and not as a MATRIX register, as previous boards do.
NAND Flash I/Os are connected to D16–D23, thus
SFR_CCFG_EBICSA.NFD0_ON_D16 is set to 1.

Tested using mtd-utils.

- patches [1, 7] add support for the sam9x60 nand controller. I would
  suggest to get them through linux-mtd tree, if all agree.
- patch 8 can be taken by Alexandre
- patch 9 - SPDX change, can be taken by Lee
- patch 10 - SPDX change, can be taken by Alexandre
- patch 11 - SPDX change, should go through linux-mtd

dt compatible string for "microchip,sam9x60-sfr" has already been
submited at https://patchwork.kernel.org/patch/10799831/

Tudor Ambarus (11):
  ARM: at91: add sam9x60 SFR definitions
