spi: rspi: Relax DMA dependency and increase build coverage

2014-07-10T10:36:11Z

As of commit ab116a4df4942c78c189d9b0744dd940ab9e00b9 ("dmaengine: shdma: fix a build failure on platforms with no DMA support"), the DMA filter function shdma_chan_filter() is sufficiently abstracted to allow building without DMA support. Hence drop the SH_DMAE_BASE dependency on SUPERH. Also increase build coverage by allowing the driver to be enabled if COMPILE_TEST=y. Signed-off-by: Geert Uytterhoeven Signed-off-by: Mark Brown

spi/rockchip: Add dependencies on relaxed I/O accessors

2014-07-05T11:51:52Z

Without the dependencies for the accessors the driver can be enabled on architectures where it will fail to build. Signed-off-by: Mark Brown

spi/rockchip: add driver for Rockchip RK3xxx SoCs integrated SPI

2014-07-04T18:32:29Z

In order to facilitate understanding, rockchip SPI controller IP design looks similar in its registers to designware. But IC implementation is different from designware, So we need a dedicated driver for Rockchip RK3XXX SoCs integrated SPI. The main differences: - dma request line: rockchip SPI controller have two DMA request line for tx and rx. - Register offset: RK3288 dw SPI_CTRLR0 0x0000 0x0000 SPI_CTRLR1 0x0004 0x0004 SPI_SSIENR 0x0008 0x0008 SPI_MWCR NONE 0x000c SPI_SER 0x000c 0x0010 SPI_BAUDR 0x0010 0x0014 SPI_TXFTLR 0x0014 0x0018 SPI_RXFTLR 0x0018 0x001c SPI_TXFLR 0x001c 0x0020 SPI_RXFLR 0x0020 0x0024 SPI_SR 0x0024 0x0028 SPI_IPR 0x0028 NONE SPI_IMR 0x002c 0x002c SPI_ISR 0x0030 0x0030 SPI_RISR 0x0034 0x0034 SPI_TXOICR NONE 0x0038 SPI_RXOICR NONE 0x003c SPI_RXUICR NONE 0x0040 SPI_MSTICR NONE 0x0044 SPI_ICR 0x0038 0x0048 SPI_DMACR 0x003c 0x004c SPI_DMATDLR 0x0040 0x0050 SPI_DMARDLR 0x0044 0x0054 SPI_TXDR 0x0400 NONE SPI_RXDR 0x0800 NONE SPI_IDR NONE 0x0058 SPI_VERSION NONE 0x005c SPI_DR NONE 0x0060 - register configuration: such as SPI_CTRLRO in rockchip SPI controller: cr0 = (CR0_BHT_8BIT << CR0_BHT_OFFSET) | (CR0_SSD_ONE << CR0_SSD_OFFSET); cr0 |= (rs->n_bytes << CR0_DFS_OFFSET); cr0 |= ((rs->mode & 0x3) << CR0_SCPH_OFFSET); cr0 |= (rs->tmode << CR0_XFM_OFFSET); cr0 |= (rs->type << CR0_FRF_OFFSET); For more information, see RK3288 chip manual. - Wait for idle: Must ensure that the FIFO data has been sent out before the next transfer.

spi/topcliff-pch: Fix Kconfig dependencies

2014-05-16T19:07:53Z

The spi-topcliff-pch driver is for a companion chip to the Intel Atom E600 series processors. These are 32-bit x86 processors so the driver is only needed on X86_32. Add COMPILE_TEST as an alternative, so that the driver can still be build-tested elsewhere. Signed-off-by: Jean Delvare Signed-off-by: Mark Brown

spi: cadence: Add dependency on ARM

2014-04-15T11:17:07Z

Add dependency on ARM in Kconfig. This is to fix the build error related to _relaxed IO. Remove dependency on SPI_MASTER because this is already defined under if SPI_MASTER in Kconfig. Signed-off-by: Harini Katakam Signed-off-by: Mark Brown
