[PATCH v3 0/3] ARM: dts: aspeed: anacapa: SGPIO updates and interrupt wiring

[Colin Huang]

This series updates the SGPIO-related device tree definitions for the
Facebook Anacapa BMC platform.

The original change was submitted as a single patch. Based on reviewer
feedback, the update has been split into three logical patches to
separate concerns and improve reviewability:

1. Fix SGPIOM0 GPIO line naming for the RMC leak detect signal.
   This patch corrects the placement of LEAK_DETECT_RMC_N without
   changing functionality.

2. Update SGPIO GPIO line names and mappings.
   This patch reworks SGPIOM0 GPIO line names and signal assignments to
   match the current hardware wiring, improving correctness and clarity.

3. Add SGPIO interrupt wiring for PCA9555 GPIO expanders.
   This patch connects the PCA9555 gpio at 24 nodes to the SGPIO interrupt
   controller to enable proper interrupt handling.

Changes in v3:
- Split the original patch into three smaller patches based on reviewer feedback.
- Remove references to external documents from commit messages. 
- Link to v2: https://lore.kernel.org/r/20260226-anacapa-dts-sgpio-v2-1-fd76828616b8@gmail.com

Changes in v2:
- Add interrupt-parent and interrupts properties to PCA9555 nodes to
  enable proper interrupt handling required by phosphor-gpio-monitor.
- Clarify DFT motivation in the commit message and mention the source
  mapping (Helios_SGPIO_BIT_MAP.xlsx rev: 2026-02-16).
- Minor wording cleanups in the commit message (line names vs. mappings).
- Rebase onto the latest tree to account for intervening commits.
- Link to v1: https://lore.kernel.org/r/20260202-anacapa-dts-sgpio-v1-1-a3a7b0b087f0@gmail.com
