Zephyr deprecates passing the chip-select delay as the variadic delay argument to SPI_DT_SPEC_INST_GET. Remove that deprecated macro argument from the raw LLCC68 device initializer. Add spi-cs-setup-delay-ns and spi-cs-hold-delay-ns defaults to the custom LLCC68 devicetree binding. Both defaults are 100000 ns, preserving the previous 100 us delay behavior while using the current Zephyr SPI devicetree properties. Verified with cmake -S . -B build and cmake --build build from the parent application.

Semtech LLCC68 radio transceiver used with the Weihua application driver.
|
|
|
|
This compatible intentionally differs from Zephyr's upstream
|
|
semtech,llcc68 binding so the application-owned driver can coexist
|
|
with Zephyr releases that ship a native LLCC68 binding and driver.
