Hi !
I'm trying to use the sp804 timer of the Foundation model to generate interrupts. I'm unsure about the timer frequency I should use, since there is no entry in the example dtb.
My sp804 driver has been tested on Qemu / Rpi to be quite accurate, and with foundation, I need to set my timer frequency to about 1000 Hz to get accurate interrupt, which seems odd.
How can I find the exact frequency of the sp804 on this model ?
Best,
V.
After a few test, I confirm that without the override bit set to 1, the frequency seems to be 32 Khz, but with the override bit (see ATF code) we can have the full 35 Mhz.
Thank you sir !
