Merge series "spi: spi-sun6i: One fix and some improvements" from Marc Kleine-Budde <mkl@pengutronix.de>:
Hello,
this series first fixes the calculation of the clock rate. The driver will
round up to the nearest clock rate instead of rounding down. Resulting in SPI
devices accessed with a too high SPI clock.
The remaining patches improve the performance of the driver. The changes range
from micro-optimizations like reducing MMIO writes to the controller to
reducing the number of needed interrupts in some use cases.
regards,
Marc

use FIELD_GET instead of open coding it
(tnx: Maxime Ripard)
- 05/10: "spi: spi-sun6i: sun6i_spi_get_tx_fifo_count: Convert manual shift+mask to FIELD_GET()"
