[PATCH 0/4] DRA7 Timer12 Support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Hi Tony,

The DRA7 Timer12 is completely missing from the kernel. This series
adds the support for it, so that all the Timers on DRA7 are represented
in the kernel. Timer12 is a special Timer, and is not available for
kernel on HS devices, very much similar to the equivalent timer on OMAP3. 

Patch 1 is a bit debatable, as I am not entirely sure if the clk API used
are acceptable outside the drivers/clk folders. It keeps intact the
omap_dm_timer_set_source() API though, and allows it to handle the
non-configurability of Timer12 parent within that API. The need for
this API is questionable, I am not a big fan as the dmtimer code blindly
tries to set the source of every requested API to OMAP_TIMER_SRC_32_KHZ,
and then the requestors would have to reset the proper parent source again.
It also supports configuring only one of 3 parents (which are valid when
added originally for the then SoCs), requiring specific clock aliases to
work across different SoCs, but the DRA7 SoC does have more than 3
configurable clock parents, and the indexes may not necessarily match
for different timers on different SoCs. Patch 1 won't be needed if we
can kill the omap_dm_timer_set_source() API.

Patches baselined on 4.3-rc3, but should apply just fine on -rc1 as well.

regards
Suman
