This is my forth version of the patch series adding generic support
for multi-chip NAND devices to the FSL-UPM driver and support for
the Micron MT29F8G08FAB NAND flash memory on the TQM8548 modules.
It addresses the issues reported on the mailing list, e.g. the new
bindings are now documented as well:
NAND: FSL-UPM: add multi chip support
NAND: FSL-UPM: Add wait flags to support board/chip specific delays
powerpc: NAND: FSL UPM: document new bindings
powerpc/85xx: TQM8548: Update DTS file for multi-chip support
Changes since v3:
- As Grant suggested, the property "fsl,upm-addr-line-cs-offsets"
is now used to define multi-chip support using dedicated address
lines for chip selection. This make the properties "num-chips"
and "chip-offset" obsolte.
- As Grant suggested, I added the string "tqc,tqm8548-upm-nand" to
the list of compatible devices for the TQM8548 modules in case it
turns out in the future that the "fsl,upm-addr-line-cs-offsets"
method is not generic enough.
- For multi-chip chip devices, the name "mchip" is now used in the
code to avoid confusion with the normal NAND "chip".
- Coding style fixes as pointed out by Anton.
Patch 3 and 4 should go through the powerpc maintainer(s).
Hope this patch series is fine now for inclusion into 2.6.30.
Thanks,
Wolfgang.
