Fix odroid-c4 i2c overlays, meson64-6.15

[veduco]

This is a follow up of #8352. This PR is for the meson64-6.15 kernel, where #8352 was for meson64-6.12.

The contents of #8352 are copied below.

Description

The existing odroid-c4 specific i2c overlay files that are shipped with Armbian 25.5.2 bookworm do not enable i2c functionality.
Applying this small modification to the source files, adding to the system and rebooting, i2c functionality is observed and able to be used.

How Has This Been Tested?

• Apply the original dtbo overlays. After a reboot, observe that i2c functionality is not enabled.
• Apply the fixed dts, compile to dtbo. After a reboot, observe that i2c functionality is enabled.

• Using existing overlay files, both meson-sm1-odroid-c4-i2c0.dtbo and meson-sm1-odroid-c4-i2c1.dtbo from /boot/dtb-6.12.32-current-meson64/amlogic/overlay/ with a /boot/armbianEnv.txt like so:

verbosity=1
console=both
overlay_prefix=meson
rootdev=UUID=4d762a48-122d-482b-9803-7eabc89c2bd8
rootfstype=ext4
user_overlays=
overlays=meson-sm1-odroid-c4-i2c0 meson-sm1-odroid-c4-i2c1
usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u

After a reboot, observe:

~# ls -al /sys/class/i2c-dev/
total 0
drwxr-xr-x  2 root root 0 Dec 31  1969 .
drwxr-xr-x 72 root root 0 Dec 31  1969 ..
lrwxrwxrwx  1 root root 0 Dec 31  1969 i2c-0 -> ../../devices/platform/soc/ff600000.bus/ff600000.hdmi-tx/i2c-0/i2c-dev/i2c-0

• Using the included fixed overlay files, both meson-sm1-odroid-c4-i2c0.dtso and meson-sm1-odroid-c4-i2c1.dtso (files renamed to *.dts on my test system to allow armbian-add-overlay compatibility) with a /boot/armbianEnv.txt like so:

verbosity=1
console=both
overlay_prefix=meson
rootdev=UUID=4d762a48-122d-482b-9803-7eabc89c2bd8
rootfstype=ext4
user_overlays=meson-sm1-odroid-c4-i2c0 meson-sm1-odroid-c4-i2c1
overlays=
usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u

After a reboot, observe:

~# ls -al /sys/class/i2c-dev/
total 0
drwxr-xr-x  2 root root 0 Dec 31  1969 .
drwxr-xr-x 72 root root 0 Dec 31  1969 ..
lrwxrwxrwx  1 root root 0 Dec 31  1969 i2c-0 -> ../../devices/platform/soc/ffd00000.bus/ffd1d000.i2c/i2c-0/i2c-dev/i2c-0
lrwxrwxrwx  1 root root 0 Dec 31  1969 i2c-1 -> ../../devices/platform/soc/ffd00000.bus/ffd1c000.i2c/i2c-1/i2c-dev/i2c-1
lrwxrwxrwx  1 root root 0 Dec 31  1969 i2c-2 -> ../../devices/platform/soc/ff600000.bus/ff600000.hdmi-tx/i2c-2/i2c-dev/i2c-2

We can see that the i2c-0 and i2c-1 devices are now present, and they are aliased as expected to maintain HardKernel compatibility (i.e. i2c2 is aliased to i2c-0 and i2c3 is aliased to i2c-1).

Review skipped

Review was skipped due to path filters

⛔ Files ignored due to path filters (2)

• patch/kernel/archive/meson64-6.15/overlay/meson-sm1-odroid-c4-i2c0.dtso is excluded by !patch/**
• patch/kernel/archive/meson64-6.15/overlay/meson-sm1-odroid-c4-i2c1.dtso is excluded by !patch/**

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

You can disable this status message by setting the reviews.review_status to false in the CodeRabbit configuration file.

Support

Need help? Create a ticket on our support page for assistance with any issues or questions.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
