The dw_edma_core_ops structure contains a set of the operations: device IRQ numbers getter, CPU/PCI address translation. Based on the functions semantics the structure name "dw_edma_plat_ops" looks more descriptive since indeed the operations are platform-specific. The "dw_edma_core_ops" name shall be used for a structure with the IP-core specific set of callbacks in order to abstract out DW eDMA and DW HDMA setups. Such structure will be added in one of the next commit in the framework of the set of changes adding the DW HDMA device support. Anyway the renaming was necessary to distinguish two types of the implementation callbacks: 1. DW eDMA/hDMA IP-core specific operations: device-specific CSR setups in one or another aspect of the DMA-engine initialization. 2. DW eDMA/hDMA platform specific operations: the DMA device environment configs like IRQs, address translation, etc. Signed-off-by: Cai Huoqing <cai.huoqing@linux.dev> Reviewed-by: Serge Semin <fancer.lancer@gmail.com> Reviewed-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Tested-by: Serge Semin <fancer.lancer@gmail.com> Link: https://lore.kernel.org/r/20230520050854.73160-2-cai.huoqing@linux.dev Signed-off-by: Vinod Koul <vkoul@kernel.org>
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.
