mainlining shenanigans
411b0f305b
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 |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
