To: linux-arm-kernel; +Cc: devicetree-discuss, patches
Since we have not reached the agreement on iomuxc binding, I'm dropping
that patch and reusing the iomuxc setup that is currently used by non-dt
board files. Hopefully, doing that could get the series merged for
v3.1, so that people can start playing device tree on i.mx51 babbage and
i.mx53 quick start board.
Will revisit the iomuxc device tree support, when we agree on the right
approach to do it.
Changes since v2:
* Drop iomuxc device tree support patch
Changes since v1:
* Address comments on v1 given by Grant and Sascha
* Add i.mx51 Babbage support

These two machine_descs will match on exactly the same boards because
they use the same dt_compat table. So the ard variant will probably
never get matched since it will be picked up by the IMX53_DT variant
first. Each machine_desc must have a different match table.
However, today when we were talking you asked if it would be better to
use a callback into board-specific code instead of the iomux table
that is implemented in this patch. I was fine either way, but my
opinion was that the table would probably result in less code. Well,
combined with the above problem, I think I was wrong. Since the only
difference in the ard variant is the call to
imx53_ard_weim_cs_config(), both the cs config and the iomux setup
will be simpler if both are handled in a callback. You're original
instinct was correct.

I believe I tested it working when I split them into two machine_descs.
Oh, here is the evidence :)
$ arm-linux-gnueabi-objdump -t -j .init.arch.info vmlinux
vmlinux: file format elf32-littlearm
SYMBOL TABLE:
c03d73d0 l d .init.arch.info 00000000 .init.arch.info
c03d73d0 l O .init.arch.info 0000003c __mach_desc_MX53_EVK
c03d740c l O .init.arch.info 0000003c __mach_desc_MX53_SMD
c03d7448 l O .init.arch.info 0000003c __mach_desc_MX53_LOCO
c03d7484 l O .init.arch.info 0000003c __mach_desc_MX53_ARD
c03d74c0 l O .init.arch.info 0000003c __mach_desc_IMX53_DT_ARD
c03d74fc l O .init.arch.info 0000003c __mach_desc_IMX53_DT
c03d73d0 g .init.arch.info 00000000 __arch_info_begin
c03d7538 g .init.arch.info 00000000 __arch_info_end
It seems that gcc compiles the machine_desc in bottom-up order, so ARD
still can match the correct entry. When I change the code to put
IMX53_DT_ARD before IMX53_DT, the __mach_desc_IMX53_DT_ARD goes behind
__mach_desc_IMX53_DT, in which case the ARD matching will be broken.
So yes, we need to fix it.

Ok, here you go.

I believe I tested it working when I split them into two machine_descs.
Oh, here is the evidence :)
$ arm-linux-gnueabi-objdump -t -j .init.arch.info vmlinux
vmlinux: file format elf32-littlearm
SYMBOL TABLE:
c03d73d0 l d .init.arch.info 00000000 .init.arch.info
c03d73d0 l O .init.arch.info 0000003c __mach_desc_MX53_EVK
c03d740c l O .init.arch.info 0000003c __mach_desc_MX53_SMD
c03d7448 l O .init.arch.info 0000003c __mach_desc_MX53_LOCO
c03d7484 l O .init.arch.info 0000003c __mach_desc_MX53_ARD
c03d74c0 l O .init.arch.info 0000003c __mach_desc_IMX53_DT_ARD
c03d74fc l O .init.arch.info 0000003c __mach_desc_IMX53_DT
c03d73d0 g .init.arch.info 00000000 __arch_info_begin
c03d7538 g .init.arch.info 00000000 __arch_info_end
It seems that gcc compiles the machine_desc in bottom-up order, so ARD
still can match the correct entry. When I change the code to put
IMX53_DT_ARD before IMX53_DT, the __mach_desc_IMX53_DT_ARD goes behind
__mach_desc_IMX53_DT, in which case the ARD matching will be broken.
So yes, we need to fix it.

Ok, here you go.

I noticed that the iomux setup is gone for now which makes me very
happy :) I didn't have a good feeling about this.

I know the decision is that all devices are enabled by default and must
be explicitely disabled like this. I really hope we can change this in
the future for the following reasons:
- The imx53 device tree is not complete, several devices like nand, ipu
and rtc are missing. Now when imx53.dtsi gets the nand device, all
board devicetrees have to be changed to keep the old behaviour.
- Most enabled device entries like the esdhc1 above have additional
nodes like cd-gpios anyway, so they must appear in the board tree
whereas the disabled devices just add additional churn.
