2009-04-07Blackfin SPI Driver: Make mmc_spi driver work on BlackfinWolfgang Muees
1. Rewrite of the non-dma data transfer functions to use only ONE mode of TIMOD (TIMOD=0x1). With TIMOD=0, it was not possible to set the TX bit pattern. So the TDBR = 0xFFFF inside the read calls won't work. 2. Clear SPI_RDBR before reading and before duplex transfer. Otherwise the garbage data in RDBR will get read. Since mmc_spi uses a lot of duplex transfers, this is the main cause of mmc_spi failure. 3. Poll RXS for transfer completion. Polling SPIF or TXS cannot guarantee transfer completion. This may interrupt a transfer before it is finished. Also this may leave garbage data in buffer and affect next transfer.

Add support for GPIO controlled SPI Chip Selects. To make use of this feature, set chip_select = 0 and add a proper cs_gpio to your controller_data. struct spi_board_info .chip_select = 0 struct bfin5xx_spi_chip .cs_gpio = GPIO_P### There are various SPI devices that require SPI MODE_0, and need to have the Chip Selects asserted during the entire transfer.

2009-04-07Blackfin SPI Driver: fix bug - correct usage of struct spi_transfer.cs_changeYi Li
According to comments in linux/spi/spi.h: * All SPI transfers start with the relevant chipselect active. Normally * it stays selected until after the last transfer in a message. Drivers * can affect the chipselect signal using cs_change. * * (i) If the transfer isn't the last one in the message, this flag is * used to make the chipselect briefly go inactive in the middle of the * message. Toggling chipselect in this way may be needed to terminate * a chip command, letting a single spi_message perform all of group of * chip transactions together. * * (ii) When the transfer is the last one in the message, the chip may * stay selected until the next transfer. On multi-device SPI busses * with nothing blocking messages going to other devices, this is just * a performance hint; starting a message to another device deselects * this one. But in other cases, this can be used to ensure correctness. * Some devices need protocol transactions to be built from a series of * spi_message submissions, where the content of one message is determined * by the results of previous messages and where the whole transaction * ends when the chipselect goes intactive.

2009-04-07Blackfin SPI Driver: fix bug - spi controller driver does not ↵Yi Li
assert/deassert CS correctly This bug can be observed when two SPI devices are sharing the spi bus: One device is set as SPI CS 7, another one is using SPI CS 4. In spi_bfin5xx.c: cs_active(), cs_deactive() are used to control SPI_FLG register. From the debug bellow: cs_active: flag: 0x7f91, chip->flag: 0x7f80, cs: 7 cs_active: flag: 0xef91, chip->flag: 0xef10, cs: 4 When device A (cs_7) activate CS 7, SPI_FLG is set as 0x7f91 (however, SPI_FLG should be set as 0x7f80, or 0x6f91 if in broadcast mode). Due to some HW bug (very possibly), if SPI_FLG is set as 0x7f91, SPISSEL7 is asserted, however SPISSEL4 will be asserted too (I can see this using the scope). This is unreasonable according to HRM.

2009-04-07powerpc/pmac: Fix internal modem IRQ on Wallstreet PowerBookBenjamin Herrenschmidt
The (relatively) new pmac_zilog driver doesn't use the pre-munged IRQ numbers from the macio_dev unlike other macio things, it directly maps it off the OF device-tree. It does that because it can be initialized much earlier than the registration of the macio devices, in order to get a serial console early. Unfortunately, that means that it "misses" some fixups done by the macio layer to work around missing interrupt descriptions in the device-tree of the Wallstreet machines. This patch brings the necessary workaround into the pmac_zilog driver itself to bring it back to working condition.
