This driver supports Rockchip NFC (NAND Flash Controller) found on RK3308,
RK2928, RKPX30, RV1108 and other SOCs. The driver has been tested using
8-bit NAND interface on the ARM based RK3308 platform.

Support Rockchip SoCs and NFC versions:
- PX30 and RK3326(NFCv900).
	ECC: 16/40/60/70 bits/1KB.
	CLOCK: ahb and nfc.
- RK3308 and RV1108(NFCv800).
	ECC: 16 bits/1KB.
	CLOCK: ahb and nfc.
- RK3036 and RK3128(NFCv622).
	ECC: 16/24/40/60 bits/1KB.
	CLOCK: ahb and nfc.
- RK3066, RK3188 and RK2928(NFCv600).
	ECC: 16/24/40/60 bits/1KB.
	CLOCK: ahb.

Supported features:
- Read full page data by DMA.
- Support HW ECC(one step is 1KB).
- Support 2 - 32K page size.
- Support 8 CS(depend on SoCs)

Limitations:
- No support for the ecc step size is 512.
- Untested on some SoCs.
- No support for subpages.
- No support for the builtin randomizer.
- The original bad block mask is not supported. It is recommended to use
  the BBT(bad block table).

Changes in v9:
- The nfc->buffer will realloc while the page size of the second mtd
  is large than the first one
- Fix coding style.
- Remove struct rk_nfc_clk.
- Prepend some function with rk_nfc_.
- Replace function readl_poll_timeout_atomic with readl_relaxed_poll_timeout.
- Remove function rk_nfc_read_byte and rk_nfc_write_byte.
- Don't select the die if 'check_only == true' in function rk_nfc_exec_op.
- Modify function rk_nfc_write_page and rk_nfc_write_page_raw.

You should probably rebase your patches on a more recent kernel, there
are several inconsistencies with the current core (see the kernel test
robot reports). Please consider having a look at the history to follow
the naming. If you need help, please ask!

Cheers,
Miquèl
