We could maybe restructure it a bit... Sujith ^ permalink raw reply [flat|nested] 16+ messages in thread

We could maybe > restructure it a bit... So I managed to track down the reason for this override. This is a specific hack for an Apple product that is based on Wasp in which they use their own reference clock which is 40Mhz. This override is not required for any other chip apart from Hornet, for which we maintain different arrays for 25/40 Mhz in the INI files. So, this chunk of code can be completely removed. ;-) Sujith ^ permalink raw reply [flat|nested] 16+ messages in thread

In such cases, the thermometer has to be enabled for both the chains. So, I think we need this fix. Sujith ^ permalink raw reply [flat|nested] 16+ messages in thread

To use them, however, a second HW TSF needs to be enabled. This patch allows usage of the extra timers by starting the second TSF properly. The extra set of HW timers is apparently also present in AR9287, but we enable it only for the AR9003 family.
