get 1000MHz
Hi all,
I would ask a question, maybe someone can help, which is the better way to configure the PRCM registers to get 1000MHz on AM/DM37X processor ?
You need set the multipliers and dividers apprioriately -
based on the
sysclk.
Would help to understand the context of "better"?
I'm thinking in two scenarios :
- For OMAP35X there are devices that support 600MHz as max frequency
but others supports 720MHz, I want to set by default 600MHz and if device supports 720MHz change to this frequency.
[sp] You can look at one of my patches on linux kernel to identify the device capability for 600/720MHz.
I''ll do, thanks
- For AM/DM37X, maybe I'm wrong, but the default frequency for
AM/DM37X is set to 600MHz, Like OMAP35X i want to set default to 800MHz and i device supports change to 1000MHz.
[sp] The device comes up at 600MHz for now, but there is no limitation on device to go all the way to 1GHz.
Which is the better way to do this ?
[sp] So, you are looking for common mechanism to go to highest supported frequency. Right?
Yes, I think should be interesting for all OMAP35/AM/DM37 a mechanism like this.
Thanks in advance, Enric
