linux-armv7 6.16-1 seem broken unable to boot. on Odroid XU4

[moonlinux]

Hi All,

I just tried to upgrade the linux-armv7 package for Odroid XU4 Armv7 boards.
It fails to boot because regulators are not getting initialized.

I just checked the commit

To restore functionality, could you please enable the following package configurations in the config ?

Hi,

Have you been able to test linux-armv7-6.16.1-1? And, if yes, is the issue solved?

[moonlinux]

Not yet—with my local config, it works.
The booting is currently broken due to the following commit,
But additional config changes are necessary to get it working.

commit 680ef57915db0f715e99a683c15f0f9f7c700e64
Author: André Draszik <andre.draszik@linaro.org>
Date: Wed Apr 9 21:37:29 2025 +0100

mfd: sec: Split into core and transport (i2c) drivers

Need to check the diff between exynos_defconfig and linux-armv7/config to make it work.

[graysky]

Please try 6.16.1-2 which should hit the repos when done building, see:make_clickable_callback(MAGIC_URL_FULL, ' ', 'https://github.com/archlinuxarm/PKGBUILDs/commit/e78a265710296345d69c235e7b9d2ce3b87f7476', '', ' class="postlink"')

Hi graysky,

I just checked commit e78a265710296345d69c235e7b9d2ce3b87f7476 and noticed
that the following configuration options were disabled:

scripts/config --disable CONFIG_RTC_DRV_S5M
scripts/config --disable CONFIG_COMMON_CLK_S2MPS11

These appear to be necessary for proper PMIC clock and RTC functionality on Samsung boards.
and disabling them may lead to issues.

Additionally, several configuration parameters seem to be missing—likely because they
were previously enabled by default.

You might want to compare your current linux-armv7/config against linux-stable
(specifically multi_v7_defconfig or exynos_defconfig) to identify discrepancies.

If you'd like, I can share an updated config with the necessary adjustments.

I just use Arch Linux for development on this platform.
