They depend on Maxime Ripard's SPI patches for Allwinner A10 (sun4i). I've watched the bus with a logic analyzer to make sure thing are sane, but I'm only able to go up to 10MHz on my LA. Unfortunately, the SPI chip I was using as a test device decided to die mid-way, so I was unable to test how well full-duplex communication works on these large transfers Alexandru Gagniuc (2): ARM: sun4i: spi: Allow Rx transfers larger than FIFO size ARM: sun4i: spi: Allow Tx transfers larger than FIFO size drivers/spi/spi-sun4i.c | 56 +++++++++++++++++++++++++++++++++++++++++++++---- 1 file changed, 52 insertions(+), 4 deletions(-) -- 1.8.5.3
