From: Rex Fu <[email protected]> Add PCA9554 GPIO expanders for PDB fuse monitor signals on the Anacapa DVT board. The patch adds GPIO expander definitions for both the left and right PDBs under the i2c8 multiplexer and updates the associated gpio-line-names to reflect the final signal assignments.
