Subject: [PATCH v2 09/12] spi: s3c64xx: get rid of the OF alias ID dependency
Date: Mon, 12 Feb 2024 14:03:28 +0000

Compatibles that set ``port_conf->{rx, tx}_fifomask`` are now safe to
get rid of the OF alias ID dependency. Let the driver probe even without
the alias for these.

With this we also protect the FIFO_LVL_MASK calls from
s3c64xx_spi_set_fifomask().
