2012-12-10OMAP3 SPI : Fixed bugs related to SPI transferajoy
Added posted writes (read after writes) to effect the change immediately for channel confiuration and channel enable register Disable the channel to purge receieve data in TX_ONLY mode transfer otherwise rx data will get affected by the next immediate RX_ONLY mode transfer Wait for the EOT bit to be set after last byte has been loaded to TX shift register in the the TX_ONLY mode.This ensures TX data has been completely shifted out Disable the channel in RX_ONLY mode before reading the last data from RXX register to prevent the SPI slave to transmit next word Signed-off-by: Ajoy Kumar Das <akdas75@yahoo.in> Cc: Tom Rini <trini@ti.com> Cc: jacopo mondi <j.mondi@voltaelectronics.com>
2012-10-25omap3_spi: introduce CONFIG_OMAP3_SPI_D0_D1_SWAPPEDPeter Korsgaard
D0/D1 Swapped or not is a board property, not anything specific to the am33xx SoC, so add a custom define for it. At the same time correct the bit handling for the swapped mode (DPE0 should be cleared and SI/DPE1 set). Signed-off-by: Peter Korsgaard <peter.korsgaard@barco.com>

2012-03-27omap3_spi: receive transmit modejacopo mondi
Implementation of receive-transmit mode for omap3 MCSPI. Introduces full duplex communication, needed by some spi devices (such as enc28j60). Signed-off-by: jacopo mondi <mondi@cs.unibo.it> <j.mondi@voltaelectronics.com>
