* kw_spi: add weak functions board_spi_claim/release_busValentin Longchamp2012-07-07-1/+12
| | | | | | | | | | This allows a final, board specific, step in the claim/relase_bus function for the SPI controller, which may be needed for some hardware designs.

* kw_spi: support spi_claim/release_bus functionsValentin Longchamp2012-07-07-0/+36
| | | | | | | | | | | | | These two function nows ensure that the MPP is configured correctly for the SPI controller before any SPI access, and restore the initial configuration when the access is over. Since the used pins for the SPI controller can differ (2 possibilities for each signal), the used pins are configured with CONFIG_SYS_KW_SPI_MPP.

* kw_spi: backup and reset the MPP of the chosen CS pinValentin Longchamp2012-07-07-9/+6
| | | | | | | | | This was not done before, and in the case of a shared pin (for MPP0 between NF_IO[2] and CSn) this could lead to problems. Signed-off-by: Valentin Longchamp <valentin.longchamp@keymile.com> cc: Holger Brunck <holger.brunck@keymile.com> cc: Prafulla Wadaskar <prafulla@marvell.com>
* spi: tegra2: rename tegra2_spi.* to tegra_spi.*Tom Warren2012-07-07-3/+3

* spi: Tegra2: Seaboard: fix UART corruption during SPI transactionsTom Warren2012-07-07-1/+12
| | | | | | | | | | | Simon Glass's proposal to fix this on Seaboard was NAK'd, so I removed his NS16550 references and added a small delay before SPI/UART muxing. Tested on my Seaboard with large SPI reads/writes and saw no corruption (crc's matched) and no spurious comm chars.

* spi: mxs: Allow other chip selects to workFabio Estevam2012-05-15-0/+10
| | | | | | | | | | | | MXS SSP controller may have up to three chip selects per port: SS0, SS1 and SS2. Currently only SS0 is supported in the mxs_spi driver. Allow all the three chip select to work by selecting the desired one in bits 20 and 21 of the HW_SSP_CTRL0 register.

* mx28: fix i.MX28 spi driverMatthias Fuchs2012-02-12-3/+9
| | | | | | | | | | | | | | | The generic spi flash driver (drivers/mtd/spi/spi_flash.c) uses the spi low level driver's spi_xfer() function with len=0 to deassert the SPI flash' chip select. But the i.MX28 spi driver rejects this call due to len=0. This patch implements an exception for len=0 with the SPI_XFER_END flag set. This results in an extra read with the chip select being deasserted afterwards. There seems to be no way to deassert the signal by hand.

| | | | | | | | | Added this for mmc_spi driver. Though altera spi core does not support programmable speed. It is fixed when configured in sopc-builder. Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Signed-off-by: Scott McNutt <smcnutt@psyent.com>

* | SPI: mxc_spi: replace fixed offsets with structuresStefano Babic2011-02-02-66/+28
| | | | | | | | | | | | | | | | This patch cleans driver code replacing all accesses to registers with fixed offsets with a corresponding structure. Signed-off-by: Stefano Babic <sbabic@denx.de>
* | SPI: mxc_spi: add SPI clock calculation and setup to the driverAnatolij Gustschin2011-02-02-1/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | The MXC SPI driver didn't calculate the SPI clock up to now and just used highest possible divider 512 for DATA RATE in the control register. This results in very low transfer rates. The patch adds code to calculate and setup the SPI clock frequency for transfers.

* | SPI: mxc_spi: fix swapping bug and add missing swapping in unaligned rx caseAnatolij Gustschin2011-02-02-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to shift only one time in each cycle in the swapping loop for unaligned tx case. Currently two byte shift operations are performed in each loop cycle causing zero gaps in the transmited data, so not all data scheduled for transmition is actually transmited. The proper swapping in unaligned rx case is missing, so add it as we need to put the received data into the rx buffer in the correct byte order.
