Shouldn't the rtc module have a dependency on I2C and do a
request_module on it? Building it into the kernel works, but only
because the i2c-tegra module is doing a subsys_initcall instead of
just plain module_init. Seems somewhat tenuous.
Looking at the i2c-tegra driver, I think it should be OK to built in
as it seems to have the proper device tree matches in place. I'm
curious if you tested this on any of the other boards that are built
in the multiboard armv7 kernels though.

Shouldn't the rtc module have a dependency on I2C and do a
request_module on it? Building it into the kernel works, but only
because the i2c-tegra module is doing a subsys_initcall instead of
just plain module_init. Seems somewhat tenuous.
My understanding is that lsmod output doesn't show any dependency of the
rtc driver upon ic2_tegra or tps6586_regulator, but all theses modules are
appropriately loaded and hwclock -rf /dev/rtc0 shows the right time after a
cold boot with the current kernel.
Adding theses modules within the initramfs only allows the rtc driver to be
loaded bellow 1sec too late, and as soon as there is no option for the
kernel to delay the rtc clock read, the rtc driver cannot win the race when
built as a module.
There are probably others rtc modules in that situation. But I don't know
the how they are wired...
Looking at the i2c-tegra driver, I think it should be OK to built in
as it seems to have the proper device tree matches in place. I'm
curious if you tested this on any of the other boards that are built
in the multiboard armv7 kernels though.
Testing with this scratch build:
http://kojipkgs.fedoraproject.org//work/tasks/3307/6523307/kernel-3.14.0-...
on a wandboard quad but I have issue with fedora kernel package 3.14.rc2 or
3.14-rc3, I need to find a serial to inverstigate this boot time issue.

New subject: [PATCH] [ARM] [Wandboard] Add CONFIG_RTC_DRV_SNVS as builtin
This prevent error like this
déc. 31 19:00:02 localhost kernel: drivers/rtc/hctosys.c: unable to open rtc device
(rtc0)
...
déc. 31 19:00:09 localhost kernel: snvs_rtc 20cc034.snvs-rtc-lp: rtc core: registered
20cc034.snvs-rtc-lp as rtc0
On the wandboard, this rtc isn't wired, so it can only help to save time accross
reboot

This is the file in the kernel-next tree
http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/log/arch/...
and the commit scheduled for next:
http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/ar...
But I've also squashed with this commit, that I've reported and that only
silent a potential issue with screen ordering:
https://gitorious.org/ac100/marvin24s-kernel/commit/33e721d7cfe7f558b3379...
With the kernel-next patch I can control the backlight, but I don't see any
console rising from the dark grey light. I still need to investigate, but
using tegra_defconfig worked.

I have no problem with adding patches for .dts patches generally as
they are self contained and don't affect anything outside of the
specific device so I'm happy for this in general, although it appears
from other bits of the thread it's still not quite ready yet anyway.

We should really be using KMS and modesetting here, is there a reason for this?

New subject: [PATCH 3/3] [ARM] [Wandboard] Add CONFIG_RTC_DRV_SNVS as builtin
This prevent error like this
déc. 31 19:00:02 localhost kernel: drivers/rtc/hctosys.c: unable to open rtc device
(rtc0)
...
déc. 31 19:00:09 localhost kernel: snvs_rtc 20cc034.snvs-rtc-lp: rtc core: registered
20cc034.snvs-rtc-lp as rtc0
On the wandboard, this rtc isn't wired, so it can only help to save time accross
reboot
