k3-beagle: fix malformed csi0-imx219 overlay patch (bad hunk count)

[igorpecovnik]

Problem

The BeagleY-AI CSI0 IMX219 overlay patch fails to apply on edge / linux-6.18.y kernel builds (board beagley-ai, family k3-beagle), breaking the kernel artifact:

patch: **** malformed patch at line 152: --
Failed to parse unidiff ... 'Hunk is longer than expected'
Summary: 5 total patches; 4 applied; 1 invalid_diff; 1 failed_apply
Exception: Failed to apply 1 patches.

Root cause

In 0003-arm64-dts-ti-add-beagley-ai-csi0-imx219-overlay.patch, the new-file hunk header declared @@ -0,0 +1,130 @@ but the body contains only 128 added lines. patch(1) therefore ran past the hunk and consumed the -- / 2.43.0 git signature footer as diff body. The footer's trailing space had also been stripped (-- instead of -- ).

Fix

• Hunk count +1,130 → +1,128
• Diffstat aligned (128 / 129 insertions(+))
• Restored the -- signature separator

The overlay content is unchanged and complete (brace/bracket balanced — 21/21 {}, 36/36 <>).

Verification

Both tools that failed in the build now pass against a matching Makefile context:

• git apply --check → exit 0
• patch -p1 --dry-run → exit 0

Note: this fixes the patch envelope only. Ideally the same correction lands at the source (original patch author) so it doesn't regress on the next import.

Summary by CodeRabbit

• New Features
  • Added support for the Raspberry Pi Camera V2.1 (Sony IMX219) on BeagleY-AI CSI0.
  • Expanded the BeagleY-AI overlay list so the new camera overlay is available in builds.
  • Enabled camera-related hardware configuration, including I2C, CSI-2, clock, and power setup, for improved plug-and-play camera use.
