But you have added "depend on MXS_DMA". So If you do not select the
mxs-dma, you can not see the
gpmi-nand.
that's why i think this patch is not needed.

So how CONFIG_MXS_DMA would be selected if not via defconfig?

Use the make menuconfig ARCH=arm:

"device drivers"-->"DMA engine support" -->"mxs dma support"

I prefer to have selected in the defconfig by default instead.

It is not obvious for the end user that they need to manually select
this option.

mxs_defconfig also selects CONFIG_MXS_DMA.

In mx23/mx28, the mxs-dma has many users, so it's proper to make it default.

Can't we do the same here and let imx_v6_v7_defconfig be built again?

Shawn, do you have any opinion about this?

First, I think Shawn is on holiday at the moment.

Second, recent kernel mainline from today building imx_v6_v7_defconfig 
is broken due to this.

So to make it build again, we have to enable CONFIG_MXS_DMA anyhow. As 
it seems that GPMI_NAND needs it to build, I would vote for the

depends on MXS_DMA

fix proposed by Richard

Anyhow, any chance to get the kernel mainline fixed asap?

Many thanks and best regards
