Subject: [ v3 0/3] mtd: rawnand: add STM32 FMC2 NAND flash controller driver
Date: Thu, 29 Nov 2018 17:41:00 +0100	[thread overview]
Message-ID: <1543509663-26128-1-git-send-email-christophe.kerello@st.com> (raw)

This patchset adds the support for the STMicroelectronics FMC2 NAND flash
controller found on STM32MP SOCs.

This patchset supports:
  - the command sequencer feature, a hardware accelerator for read/write
    within a page
  - the manual mode feature, useful for debug purpose
  - a maximum 8k page size
  - following ECC strength and step size
	- nand-ecc-strength = <8>, nand-ecc-step-size = <512> (BCH8)
	- nand-ecc-strength = <4>, nand-ecc-step-size = <512> (BCH4)
	- nand-ecc-strength = <1>, nand-ecc-step-size = <512> (Extended
	  ecc based on HAMMING)
    
This patchset has been tested on Micron MT29F8G08ABACAH4 (8-bit SLC NAND)
and MT29F8G16ABACAH4 (16-bit SLC NAND)

Changes v3:
 - modify clocks property description
 - add NAND reg property description
 - stm32_fmc2_nfc inherits from nand_controller structure
 - rewrite stm32_fmc2_read_data/stm32_fmc2_write_data functions
   to handle aligned and not aligned buffers
 - replace uint8_t by u8
 - use of NAND_ROW_ADDR_3 option

Changes v2:
 - separate the controller structure and the NAND chip structure
 - remove timings description from the device tree
 - fix typo issues
 - fix kbuildrobot issues
