[PATCH] spi: dt-bindings: snps,dw-abp-ssi: Allow up to 16 chip-selects

From: Rob Herring (Arm)

Date: Mon Dec 15 2025 - 18:03:28 EST


At least the Microchip Sparx5 supports up to 16 chip-selects, so
increase the maximum. The pattern for the child unit-address was
unconstrained, so update it to match the maximum number of
chip-selects.
