由 Steven King 提交于
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.

由 Jassi Brar 提交于
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.

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.

Generalize the old at91rm9200 "bootstrap" bitbanging SPI master driver as "spi_gpio", so it works with arbitrary GPIOs and can be configured through platform_data. Such SPI masters support: - any number of bus instances (bus_num is the platform_device.id) - any number of chipselects (one GPIO per spi_device) - all four SPI_MODE values, and SPI_CS_HIGH - i/o word sizes from 1 to 32 bits; - devices configured as with any other spi_master controller When configured using platform_data, this provides relatively low clock rates. On platforms that support inlined GPIO calls, significantly improved transfer speeds are also possible with a semi-custom driver. (It's still painful when accessing flash memory, but less so.) Sanity checked by using this version to replace both native controllers on a board with six different SPI slaves, relying on three different SPI_MODE_* values and both SPI_CS_HIGH settings for correct operation.

The current driver may cause glitches on SPI CLK line since one must disable the SPI controller before changing any HW settings. Fix this by implementing a local spi_transfer function that won't change speed and/or word size while CS is active. While doing that heavy lifting a few other issues were addressed too: - Make word size 16 and 32 work too. - Honor bits_per_word and speed_hz in spi transaction. - Optimize the common path. This also stops using the "bitbang" framework (except for a few constants).
