How can I procure datasheets for hardware?
I am an independent developer based in Mumbai, India. I am interested in enhancing Linux by writing device drivers for hardware on it.
How can I procure datasheets/technical documentation for the same? I am interested in SATA and SAS hardware.
Do I need to speak with the company itself? If so, would I , as an independent developer, be able to procure datasheets? (I need to get details of the register set).
Are there any other technical documents I need, for writing a device driver?
Thanks for any advice, tips.
