When this happens the registers show that the TXFIFO contains words, but the transfer is never started. We observed that on some boards which boot from SPI NOR. The xload SPI code leaves the controller enabled, so the SPI controller is enabled during probe(). Disabling it before usage (and thus resetting it) helps. We haven't found out why exactly this happens. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 10 Jan 2017
2016-12-07	76fd7b6 Browse files » spi: mvebu: fix baudrate selection for Armada 370/XP ... There are two problems that made the driver choose the wrong baudrate calculation algorithm: a) The compatible used on 370/XP isn't marvell,armada-370-xp-spi but marvell,armada-370-spi or marvell,armada-xp-spi respectively. b) The probe function uses match = of_match_node(mvebu_spi_dt_ids, dev->device_node); to determine the right algorithm. As the devices are also compatible to marvell,orion-spi and this comes first in mvebu_spi_dt_ids[] it's always the older Orion algorithm that is used. This patch fixes both problems.

2016-08-03	28a0baf Browse files » ARM i.MX31: add SPI support ... The i.MX31 SPI interface was refered by freescale as spi_ver_0_4 in one of their older vendor extended linux releases. spi_ver_0_4 differs only in minor aspects to spi_ver_0_7 (i.MX35) which is already supported by barebox. Regarding barebox, the differences boil down to the location and length of the CHIP SELECT and BIT COUNT/BURST LENGTH elements of CONREG. The spi_ver_0_4 variant is limited to single word bursts with a maximum of 32 bits_per_word. Add support for the i.MX31 SPI interface to the barebox spi_ver_0_7 implementation.
