Michael Brown	ca41159f57	Ensure clock line is in the idle state before asserting chip select.	17 年前
Udayan Kumar	c6d0ef3478	added endianness to natsemi.	17 年前
Udayan Kumar	623d10c66f	debugging natsemi.c	17 年前
Michael Brown	95cb7aaacf	Support cards such as natsemi which treat the data as little-endian (i.e. LSB transmitted first on the wire), even though SPI commands and addresses always have to be big-endian.	17 年前
Michael Brown	946967f09c	Abstracted out part of the concept of an SPI device to a generalised NVS device. Separated the mechanisms of non-volatile storage access and non-volatile stored options.	18 年前
Michael Brown	dc06c895fc	Changed length parameter in SPI methods to be a byte length, rather than a word length.	18 年前
Michael Brown	931f94dca3	Generalised the SPI abstraction layer to also be able to handle interfaces that don't provide the full flexibility of a bit-bashing interface. Temporarily hacked rtl8139.c to use the new interface.	18 年前
Michael Brown	88e38fa148	We don't actually have a stdio.h header file. Our printf() functions are defined in vsprintf.h. (This may change, since vsprintf.h is a non-standard name, but for now it's the one to use.) There should be no need to include vsprintf.h just for DBG() statements, since include/compiler.h forces it in for a debug build anyway.	18 年前
Marty Connor	6ac78f6aff	added stdio.h to includes for DBG compilation	18 年前
Michael Brown	3b51c719d3	Generalise three-wire interface to generic SPI interface. Update rtl8139 driver to instantiate an SPI interface with a three-wire device attached.	18 年前
Michael Brown	ab4f96e525	Move per-transition delays from generic bit-bashing layer to i2c layer (since SPI bit-bashing will require different delay semantics).	18 年前
Michael Brown	51a36f1cfb	Change read_bit() to return 0 or -1UL, rather than 0 or 1.	18 年前
Michael Brown	3ed40686c9	Added bit-bashing i2c interface code	18 年前
Michael Brown	e90b64d625	Added sketch of bit-bashing interface common code	18 年前
