Subject: [PATCH v4 0/2] mtd: rawnand: meson: add Amlogic NAND driver support

Precedence: bulk

  These two patches try to add initial NAND driver support for Amlogic Meson
SoCs, current it has been tested on GXL(p212) and AXG(s400) platform.


Changes since v3 at [4]:
 - remove partition table and some used props from dt-bindings 

Changes since v2 at [3]:
 - remove some hardcode time value, like twb
 - use dev wait R/B instead of nand_soft_waitrdy
 - implement nfc ecc init by ecc helper
 - rework nfc buffer init to register the maximun buffer when several chips
 - free nfc buffer when error and cleanup
 - add variable to teack all the already assigned CS lines
 - fix mtd->name use the first cs line only
 - remove dt "nand-enable-scrambler" and use NAND_NEED_SCRAMBLING instead.
 - move setuping ECC fileds after the identification phase
 - use nand_scan() and attach_chip()
 - check one event to return IRQ_NONE
 - delete cast when of_device_get_match_data
 - use nand_controller_init() helper
 - remove nfc driver complains when calling devm_ioremap_resource
 - clear irqs before setting up irq handler

Changes since v1 at [1]:
  - adopt property amlogic,nand-enable-scrambler - thanks Martin
  - drop nand pins in DT
  - convert clk access to emmc clkc model 
  - fix regiser field definition alignment
  - drop nand-user-mode 
  - parse cs id from DT
  - rework n2m, m2n function
  - explain why insert two "IDLE" command
  - implement exec_op()
  - drop meson_nfc_get_nand_chip_dts()
  - release resource once error occur in meson_nfc_nand_chips_init(), 
  - call nand_cleanup(nand) once mtd_device_register fail

Items not addressed ( or confirmed ) in this version:
  - convert to ECC conf helper() 
  - convert to dma coherent API
  - how to construct mtd->name
