adding si3210 driver
Hi All,
I have a router running linux (LEDE distribution) with an embedded 3G modem and a POTS telephone interface.
The telephone interface uses the si3210 device interfaced with the uP through an spi IF.
The si3210 ProSLIC integrates a subscriber line interface circuit (SLIC) and is commonly found in several router with telephone functions.
Because I was unable to find a driver for the si3210, I'm now using the spidev interface to control the device from the userspace.
Now I'm thinking to add a spi protocol char driver for that device.
My first question is if make sense to do this; I see other similar tentative never embedded in the mainstream:
https://github.com/stelhs/slic_tdm
https://github.com/opennetworklinux/linux-3.8.13/tree/master/drivers/tdm/line_ctrl
Second question is: What class the driver belong to? (in which drivers/ subfolder shall I add the driver)?
Thanks for the support.
Bye.
