Subject: [PATCH v3 11/16] spi: dw: Remove DW DMA code dependency from DW_DMAC_PCI
Date: Thu, 21 May 2020 04:22:01 +0300 [thread overview]
Message-ID: <20200521012206.14472-12-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20200521012206.14472-1-Sergey.Semin@baikalelectronics.ru>
Since there is a generic method available to initialize the DW SPI DMA
interface on any DT and ACPI-based platforms, which in general can be
designed with not only DW DMAC but with any DMA engine on board, we can
freely remove the CONFIG_DW_DMAC_PCI config from dependency list of
CONFIG_SPI_DW_DMA. Especially seeing that we don't use anything DW DMAC
specific in the new driver.
