[v5,00/12] mtd: rawnand: brcmnand: driver and doc updates

Message

William Zhang Feb. 7, 2024, 8:22 p.m. UTC

This patch series is an update from the previous version [1] after
exex_op support and fixes (patch 1 to 4 from the previous version.)

It updates all the BCMBCA SoC to support the nand controller and add
functions to handle BCMBCA specific needs on ECC and Write Protection
usage. The device tree document is also updated accordingly with the new
properties needed by the driver.

In addition there is a bug fix for exec_op helper functions and log
level adjustment on uncorrectable ECC error.

Changes in v5:
- Add reviewed-by tag for the first patch of the yaml change
- Update the description for the WP connection and strap ecc properties
  based on the feedbacks
- Add check in dts binding to ensure the strap ecc property and core 
  nand ecc property can not be used at the same time
- Update the commit message for the log level change patch

Changes in v4:
- Split the yaml changes into three patches.
- Move the WP pin property to a new patch and change it to boolean type.
- Move ecc strap property to a new patch and remove some non-binding 
  related text from the description
- Add a new patch for bcm4908 based router board dts update
- Move the board related dts setting from SoC dtsi to board dts
- Update the comments for ecc setting selection
- Use the new brcm,wp-not-connected property based on the dts binding
  change
- Fix the commit id in the fixes tag
- Revert the log level change for correctable ecc error

Changes in v3:
- Update brcm,nand-use-wp description
- Revert the description change to BCM63168 SoC-specific NAND controller
- Updated bcmbca_read_data_bus comment

Changes in v2:
- Revert the new compatible string nand-bcmbca
- Drop the BCM63168 compatible fix to avoid any potential ABI
  incompatibility issue
- Simplify the explanation for brcm,nand-use-wp
- Keep the interrupt name requirement when interrupt number is specified
- Add nand controller node label for 4908 so it is consistent with other
  SoC's and can be referenced by board dts file
- Drop the is_param argument to the read data bus function now that we
  have the exec_op API to read the parameter page and ONFI data
- Minor cosmetic fixes
- Added patches 8, 9, 10 to patch series
