Programmable clock in salvator-x

Programmable clock in salvator-x

[Hamza Farooq]

Hi,

in order to use IDT 5P49V5923A programmable clock for DU, I was
wondering if the driver for it is already available/present in the
Linux source tree. It seems to be present on the board but not
used/enabled from salvator-x device tree.

programable_clk0 and programable_clk01 seem to be used in du node but
not associated with IDT clock chip. Or am I overlooking something?

Thanks and best regards,
Hamza

All clock drivers are available in drivers/clk/. Quickly looking through that 
direction I don't see a driver specifically for the 5P49V5923A. If the chip is 
pin-to-pin compatible with another component from a different vendor you might 
be to reuse one of the existing drivers, otherwise you will need to develop a 
new one.
