| | * | spi: xilinx_spi: Fix up I/O routine wrapping bogosity.Paul Mundt2010-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | xilinx_spi presently makes some fairly questionable assumptions about I/O routines, and attempts to assign ioread32/iowrite32 and friends directly to its own internal function pointers. On many platforms these I/O routines are macros or wrappers and not actual functions on their own, resulting in things like: ERROR: "ioread32be" [drivers/spi/xilinx_spi.ko] undefined! ERROR: "iowrite32be" [drivers/spi/xilinx_spi.ko] undefined! ERROR: "iowrite32" [drivers/spi/xilinx_spi.ko] undefined! ERROR: "ioread32" [drivers/spi/xilinx_spi.ko] undefined! If xilinx_spi wants to do this sort of casting, it needs to provide its own wrappers for these, or change how it does accesses completely. I've opted for the first approach, and the attached silly patch does that. If someone with the hardware available wants to give the second option a try that's ok too. In any event, the current code is broken for at least: arm, avr32, blackfin, microblaze, mn10300, and sh.

| | * | spi: Add Freescale/Motorola Coldfire QSPI driverSteven King2010-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the QSPI controller found some on Freescale/Motorola Coldfire MCUs. Full duplex, active high cs, spi modes 0-3 and word sizes 8-16 bits are supported. The hardware drives the MISO, MOSI and SCLK lines, but the chip selects are managed via GPIO and must be configured by the board code. The QSPI controller has an 80 byte buffer which allows us to transfer up to 16 words at a time. For transfers longer than 16 words, we split the buffer in half so we can update in one half while the controller is operating on the other half. Interrupt latencies then ultimately limits our sustained thru-put to something less than half the maximum speed supported by the part.

|/ | | | | | | | | | | | | | | | The spi_sh_msiof.c driver presently misconfigures REDG and TEDG. TEDG==0 outputs data at the **rising edge** of the clock and REDG==0 samples data at the **falling edge** of the clock. Therefore for SPI, TEDG must be equal to REDG, otherwise the last byte received is not sampled in SPI mode 3. This brings the driver in line with the SH7723 HW Reference Manual settings documented in Figures 20.20 and 20.21 ("SPI Clock and data timing").

| * spi: Add s3c64xx SPI Controller driverJassi Brar2009-12-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each SPI controller has exactly one CS line and as such doesn't provide for multi-cs. We implement a workaround to support multi-cs by _not_ configuring the mux'ed CS pin for each SPI controller. The CS mechanism is assumed to be fully machine specific - the driver doesn't even assume some GPIO pin is used to control the CS. The driver selects between DMA and POLLING mode depending upon the xfer size - DMA mode for xfers bigger than FIFO size, POLLING mode otherwise. The driver has been designed to be capable of running SoCs since s3c64xx and till date, for that reason some of the register fields have been passed via, SoC specific, platform data.

| * atmel_spi: fix dma addr calculation for len > BUFFER_SIZEBen Nizette2009-12-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If len > BUFFER_LEN and !xfer->rx_buf we end up calculating the tx buffer address as *tx_dma = xfer->tx_dma + xfer->len - BUFFER_SIZE; which is constant; i.e. we just send the last BUFFER_SIZE data over again until we've reached the right number of bytes. This patch gets around this by using the /requested/ length when calculating addresses. Note there's no way len != *plen when we calculate the rx buffer address but conceptually we should be using *plen and I don't want someone to come through later, see the calculations for rx and tx are different and "clean up" back to what we had.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add pseudo-DMA by FIQ to the S3C24XX SPI driver. This allows the driver to get DMA-like performance where there are either no free DMA channels or when doing transfers that required both TX and RX data paths. Since this patch requires the addition of an assembly file to hold the FIQ code, we rename the module (instead of adding a rename of the .c file to this patch). We expect most users are loading this via udev and thus there should be no change to the userland configuration.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is V2 of SPI Master support for the SuperH MSIOF. Full duplex, spi mode 0-3, active high cs, 3-wire and lsb first should all be supported, but the driver has so far only been tested with "mmc_spi". The MSIOF hardware comes with 32-bit FIFOs for receive and transmit, and this driver simply breaks the SPI messages into FIFO-sized chunks. The MSIOF hardware manages the pins for clock, receive and transmit (sck/miso/mosi), but the chip select pin is managed by software and must be configured as a regular GPIO pin by the board code. Performance wise there is still room for improvement, but on a Ecovec board with the built-in sh7724 MSIOF0 this driver gets Mini-sd read speeds of about half a megabyte per second. Future work include better clock setup and merging of 8-bit transfers into 32-bit words to reduce interrupt load and improve throughput.

| | | | | | | | | | | | | | | | The function plat_mpc8xxx_spi_remove is defined using __devexit, so don't use __exit_p but __devexit_p to wrap it. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
| * spi/i.MX: fix broken error handling for gpio_requestJohn Ogness2009-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | i.MX35-provided chipselects are represented using negative numbers. If gpio_request() fails and the previous chipselect was a negative number, the while loop is endless (i is never decremented). Also, the error loop would never call gpio_free on chipselect[0]. And finally, the error message was missing an endline. Signed-off-by: John Ogness <john.ogness@linutronix.de> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
| * spi/i.mx: drain MXC SPI transfer buffer when probing deviceDaniel Mack2009-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | On the MX31litekit, the bootloader seems to communicate with the MC13783 PMIC chip before booting Linux. However, it does not flush all the buffers properly after that, which makes the imx-spi driver read bogus data when probing the MC13783. Fix that by draining the SPI receive buffer on startup.
