pci1xxxx_spi_transfer_with_dma adds DMA support to copy the data between host cpu buffer and SPI IO Buffer. On DMA Completion interrupt, the next SPI transaction is initiated in isr. Helper functions pci1xxxx_spi_setup, pci1xxxx_spi_setup_dma_from_io, pci1xxxx_spi_setup_dma_to_io and pci1xxxx_start_spi_xfer are added for setting up spi, setting up dma operations, and to start spi transfer respectively. In the existing implementation, codes are replaced with helper functions wherever applicable. Signed-off-by:

In PCI1xxxx C0, support for DMA in PCIe endpoint is added to enhance the SPI performance. With this support, the performance is improved from 6Mbps to 17Mbps with 20Mhz clock. - DMA Supports two Channels, 0 and 1 - SPI Instance 0 uses chan 0 and SPI Instance 1 uses chan 1 - DMA can be used only if SPI is mapped to PF0 in the multi function endpoint and the MSI interrupt is supported - MSI interrupt of one of the SPI instance is assigned to the DMA and both channels 0 and 1 share the same irq, the MSI address and MSI Data of the irq is obtained and stored in DMA registers to generate interrupt Signed-off-by:

Add support for GS101 SPI. GS101 integrates 16 SPI nodes, all with 64 bytes FIFOs. GS101 allows just 32 bit register accesses, otherwise a Serror Interrupt is raised. Do the write reg accesses in 32 bits. Reviewed-by:

Allow SoCs that require 32 bits register accesses to write data in chunks of 8 or 16 bits. One SoC that requires 32 bit register accesses is the google gs101. The operation is rare, thus open code it in the driver rather than making it generic (through asm-generic/io.h). Signed-off-by:

There are SoCs (gs101) that allow only 32 bit register accesses. As the requirement is rare enough, for those SoCs we'll open code in the driver some s3c64xx_iowrite{8,16}_32_rep() accessors. Prepare for such addition. Suggested-by: -
