2010-09-30MXC: Correct SPI_CPOL setting in SPI driverStefano Babic
The handling of the SPI_CPOL bit inside the SPI driver was wrong. As reported by the manual, the meaning of the SSPOL inside the configuration register is the same as reported by SPI specification (0 if low in idle, 1 is high on idle). The driver inverts this logic. Because this patch sets the logic as specified, it is required to clear the CPOL bit in the configuration file to adapt to the correct logic.

All in-tree boards that use this controller have CONFIG_NET_MULTI added Also: - changed CONFIG_DRIVER_CS8900 to CONFIG_CS8900 - changed CS8900_BASE to CONFIG_CS8900_BASE - changed CS8900_BUS?? to CONFIG_CS8900_BUS?? - cleaned up line lengths - modified VCMA9 command function that accesses the device - removed MAC address initialization from lib_arm/board.c Signed-off-by: Ben Warren <biggerbadderben@gmail.com> Tested-by: Wolfgang Denk <wd@denx.de> Acked-by: Wolfgang Denk <wd@denx.de>
2009-06-21serial_mx31: allow it to work with mx27 too and rename to serial_mxcIlya Yanok
UART hardware on i.MX27 is the same as on the i.MX31 so we just need to provide the driver with correct address of the registers. Signed-off-by: Ilya Yanok <yanok@emcraft.com>
2009-03-20Separate mtdparts command from jffs2Stefan Roese
Currently the mtdparts commands are included in the jffs2 command support. This doesn't make sense anymore since other commands (e.g. UBI) use this infrastructure as well now. This patch separates the mtdparts commands from the jffs2 commands making it possible to only select mtdparts when no JFFS2 support is needed.

2008-10-08i.MX31: switch to CFG_HZ=1000Guennadi Liakhovetski
Switch to the standard CFG_HZ=1000 value, while at it, minor white-space cleanup, remove CFG_CLKS_IN_HZ from config-headers. Tested on mx31ads, provides 2% or 0.4% precision depending on the CONFIG_MX31_TIMER_HIGH_PRECISION flag. Measured with stop-watch on 100s boot-delay. Signed-off-by: Guennadi Liakhovetski <lg@denx.de>

2008-09-12i.MX31: Make the SPI bus and chip select configurable for MC13783Magnus Lilja
The i.MX31 has three SPI buses and each bus has several chip selects and the MC13783 chip can be connected to any of these. The current RTC driver for MC13783 is hardcoded for CSPI2/SS2. This patch makes make MC13783 SPI bus and chip select configurable via CONFIG_MC13783_SPI_BUS and CONFIG_MC13783_SPI_CS. Signed-off-by: Magnus Lilja <lilja.magnus@gmail.com>

2008-06-03SPI API improvementsHaavard Skinnemoen
This patch gets rid of the spi_chipsel table and adds a handful of new functions that makes the SPI layer cleaner and more flexible. Instead of the spi_chipsel table, each board that wants to use SPI gets to implement three hooks: * spi_cs_activate(): Activates the chipselect for a given slave * spi_cs_deactivate(): Deactivates the chipselect for a given slave * spi_cs_is_valid(): Determines if the given bus/chipselect combination can be activated. Not all drivers may need those extra functions however. If that's the case, the board code may just leave them out (assuming they know what the driver needs) or rely on the linker to strip them out (assuming --gc-sections is being used.) To set up communication parameters for a given slave, the driver needs to call spi_setup_slave(). This returns a pointer to an opaque spi_slave struct which must be passed as a parameter to subsequent SPI calls. This struct can be freed by calling spi_free_slave(), but most driver probably don't want to do this. Before starting one or more SPI transfers, the driver must call spi_claim_bus() to gain exclusive access to the SPI bus and initialize the hardware. When all transfers are done, the driver must call spi_release_bus() to make the bus available to others, and possibly shut down the SPI controller hardware. spi_xfer() behaves mostly the same as before, but it now takes a spi_slave parameter instead of a spi_chipsel function pointer. It also got a new parameter, flags, which is used to specify chip select behaviour. This may be extended with other flags in the future. This patch has been build-tested on all powerpc and arm boards involved. I have not tested NIOS since I don't have a toolchain for it installed, so I expect some breakage there even though I've tried fixing up everything I could find by visual inspection. I have run-time tested this on AVR32 ATNGW100 using the atmel_spi and DataFlash drivers posted as a follow-up. I'd like some help testing other boards that use the existing SPI API. But most of all, I'd like some comments on the new API. Is this stuff usable for everyone? If not, why? Changed in v4: - Build fixes for various boards, drivers and commands - Provide common struct spi_slave definition that can be extended by drivers - Pass a struct spi_slave * to spi_cs_activate and spi_cs_deactivate - Make default bus and mode build-time configurable - Override default SPI bus ID and mode on mx32ads and imx31_litekit. Changed in v3: - Add opaque struct spi_slave for controller-specific data associated with a slave. - Add spi_claim_bus() and spi_release_bus() - Add spi_free_slave() - spi_setup() is now called spi_setup_slave() and returns a struct spi_slave - soft_spi now supports four SPI modes (CPOL|CPHA) - Add bus parameter to spi_setup_slave() - Convert the new i.MX32 SPI driver - Convert the new MC13783 RTC driver Changed in v2: - Convert the mpc8xxx_spi driver and the mpc8349emds board to the new API.

2008-05-10mx31ads: fix 32kHz clock handlingGuennadi Liakhovetski
According to schematics and to RedBoot sources, the MX31ADS uses a 32768Hz oscillator as a SKIL source. Fix previously wrongly assumed 32000Hz value. Also fix a typo when verifying a jumper configuration. While at it, make two needlessly global functions static. Signed-off-by: Guennadi Liakhovetski <lg@denx.de>
