* making SPI CS optional * CS pin should be declared as optional or required in CONFIG_SCHEMA * changed SPI_DEVICE_SCHEMA to a function, like i2c * added spi_device_schema() to pcd8544, lint fixes * updated max31856 with new spi_device_schema() * cleanup imports Co-authored-by: Ilya Goldberg <iggie@mac.com>
