spi: pxa2xx: limit reaches -1

2009-04-21T20:41:49Z

On line 944 the return value of flush() is considered as a boolean, but limit reaches -1 upon timeout which evaluates to true. On 540, 594, 720 the same occurs for wait_ssp_rx_stall() On 536 the same occurs for wait_dma_channel_stop() Signed-off-by: Roel Kluin Acked-by: Eric Miao Cc: David Brownell Cc: Russell King Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

pxa2xx_spi: restore DRCMR on resume

2009-04-21T20:41:49Z

If DMA is enabled, any spi_sync call after suspend/resume would block forever, because DRCMR is lost on suspend. This patch restores DRCMR to the same values set by probe. Signed-off-by: Daniel Ribeiro Signed-off-by: David Brownell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

spi: spi_write_then_read() bugfixes

2009-04-13T22:04:30Z

The "simplify spi_write_then_read()" patch included two regressions from the 2.6.27 behaviors: - The data it wrote out during the (full duplex) read side of the transfer was not zeroed. - It fails completely on half duplex hardware, such as Microwire and most "3-wire" SPI variants. So, revert that patch. A revised version should be submitted at some point, which can get the speedup on standard hardware (full duplex) without breaking on less-capable half-duplex stuff.

spi: pxa2xx_spi: introduce chipselect GPIO to simplify the common cases

2009-04-07T15:31:07Z

Most SPI peripherals use GPIOs as their chip selects, introduce .gpio_cs for this. Signed-off-by: Eric Miao Cc: David Brownell Cc: Russell King Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
