Connection between flash and controller is not necessary to be always
of same type. It may varies from platform to platform.
Adding endianness (optional) property to provide connection type
information. This endianness property is checked in physmap_of_core.c
to decide swap type.
This patch also set "big-endian" property for ls1021a, ls1043a
and ls1046a device tree. here connection between IFC controller
and NOR flash is big-endian.
Prabhakar Kushwaha (4):
dt-bindings: mtd-physmap: Add endianness supports
driver: mtd: update struct map_info's swap as per map requirement
ARM: dts: Add NOR connection type with IFC
ARM64: dts: Add NOR connection type with IFC
Resending as all patches of patchset never reaches to patchwork.

It is not necessary for all device's maps to be CFI_HOST_ENDIAN.
Maps device can be Big endian or little endian.
Currently it is being taken care using CONFIG_MTD_CFI_LE_BYTE_SWAP or
CONFIG_MTD_CFI_BE_BYTE_SWAP i.e. compile time.
Now update struct map_info's swap field based on device characteristics
defined in device tree.

Connection between IFC and NOR flash is of big-endian type.
So add big-endian property in flash node to reflect the same.

Again, that's not the case, I just marked them as "Not applicable" (see
my previous reply).
Also, according to the cover letter this patch should not be part of
"dt-bindings: mtd-physmap: Add endianness supports", so why are you
sending it here?

LS1021AQDS support NAND flash on IFC chip-select 2.
So add NAND node in device tree for IFC controller.

Due to patch series http://patchwork.ozlabs.org/project/linux-mtd/list/?series=28735
this patch is now independent of flash propoerty. So resending.
Resending as all patches of patchset never reaches to patchwork.

First of all, can you stop sending dts changes until we've agreed on
the dt-bindings/driver changes.

Hm, I think they reached patchwork, it's just that dts changes won't
be applied to the MTD tree, so I mark them as 'Not applicable'.
