If there's only one master driver which supports this flag, it sounds
to me like it woul

Hi Everybody,
I am using a SPI based 12 bit adc(max1241) from maxim.I am trying to read
the value from adc using spi_read() in linux kernel.But every time i used
to read i am getting *0xff* only.(i have to read two consecutive bytes).To
the adc chip i am probing with CRO which always shows DOUT p

Have a look here[1]. The code certainly isn't finished (we're at a
similar stage of development as you, it seem), but you shoul

Don't think you need to anything 'ADC specific' all u need is to _use_
your SPI driver.
grep for spi_sync in linux/drivers/ and refer to any spi use
Hi all,
Thanks for the suggestions.
Actually i am new to SPI,and all related ADC drivers in the latest kernels
are through I2C.i am going to use an temperature module through this adc
connected through SPI.so i think i am going to read the data only,no data
writing is required.
Let us try and se

The ḱernel does not contain any generic ADC subsystem abstraction (I
think it would be good if it did), instead most drivers using ADC have
their ADC portions stored inside a

Hi everybody,
can anybody share how to start a spi based ADC linux driver.I am having a
MAXIM 1242 ADC chip.
Can anybody share some reference driver for the same chip
Thanks in advance
