Subject: spi: dt-bindings: snps,dw-abp-ssi: Allow up to 16 chip-selects
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1d24636a9c87c32ec626a56593c98544e6c49fef;p=thirdparty%2Fkernel%2Flinux.git

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

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.
