Forums - [MDM9607] Adding a clock for a crystal oscillator in the device tree

Hello,

I'm not really sure if this is the correct forum, my apologies in advance if it isn't. We are currently using a Qualcomm MDM9607 based chipset for our telematics device. We are trying to interface with Microchip MCP2515 via SPI. The CAN SPI driver for the MCP2515 is already available in the SDK, it only needs the device tree to be adjusted for the driver to work. Using a solution similar to that recommended by one user on the Dragonboard Forums, I'm trying to get it working on our board too. 

This is the code from the user on the forum

clocks 
{ 
clk16m: oscillator 
{ #clock-cells = <0>;
  compatible = "fixed-clock"; 
 clock-frequency = <16000000>; 
}; 
}; 
 

However it seems qcom's implementation of the clocks are slightly different to that of native linux implementation. I've been trying to assign a fixed-clock to the MCP2515 without no results.  

I found the Peripheral Programming Guide, for Dragonboard. I see examples of how to add clock for UART etc, but I'm just wondering if I'm on the right track at all.. 

How would I create such a fixed clock for an external oscillator?  What changes do I make to the clock-gcc-mdm9607.c file?
