Subject: [RFC] spi: dw: support setting tmode dynamically
Date: Wed, 23 Dec 2015 19:23:38 +0800 [thread overview]
Message-ID: <20151223192338.128e95a4@xhacker> (raw)
Hi all,
Currently the spi-dw tmode is fixed to SPI_TMOD_TR if cs_control is NULL, but we
need to set it as SPI_TMOD_EPROMREAD to read nor flash, my solution is to add and
export one functions to set the tmode, then the nor flash driver call it
before reading and set back to SPI_TMOD_TR after done.
Is there any elegant solution from SPI framework? Any suggestions are appreciated!
Thanks,
Jisheng
