X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=411b0f305b4ba05a7bae6b0fe924d02a3086eed6;p=linux.git Merge series "spi: spi-sun6i: One fix and some improvements" from Marc Kleine-Budde : 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 changes since v1: - added Maxime Ripard's to the existing patches - 06/10: (was 05/10 in v1) "spi: spi-sun6i: sun6i_spi_drain_fifo(): introduce sun6i_spi_get_rx_fifo_count() and make use of it" 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()" new patch _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel --- 411b0f305b4ba05a7bae6b0fe924d02a3086eed6
