Subject: [PATCH 0/9] spi: spi-sun6i: One fix and some improvements
Date: Mon,  6 Jul 2020 09:17:52 +0200	[thread overview]
Message-ID: <20200706071801.558394-1-mkl@pengutronix.de> (raw)

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
