[PATCH v1 9/9] spi: pxa2xx: Use predefined mask when programming FIFO thresholds

From: Andy Shevchenko
Date: Mon May 17 2021 - 10:04:09 EST


The predefined mask for threshold modification can be used
in case of Intel Merrifield SPI. Replace open-coded value
with predefined mask when programming FIFO thresholds.
