This patchset adds initial support for the clocks controlled by

It depends on Bjorn's Qualcomm SMD & RPM patches, that are now in
linux-next: https://lkml.org/lkml/2015/7/27/1125
The first patch implements the RPM clock operations, which are
using a shared memory for sending requests to the RPM processor.
The second patch adds the support of RPM clocks on the MSM8916
platform.
I pulled this set into my local tree and added a MSM8974 driver; so I
could enable cxo_a2 and load the WCNSS firmware. This works great.
Thanks for trying it.
I do however have a problem that if I revise the gcc and mmcc drivers to
be rooted in cxo_clk_src (like you have for 8916) the clk_set_rate() in
msm_serial messes up my uart - way before the rpmcc driver is loaded.
I have not debugged this further (as it wasn't needed for my usecase),
but have you seen any issues related to this?
I am not seeing this on 8916 and don't remember seeing in on 8974, but
will give it a try again next week when i will have a 8974 board.
Will you be able to send out v3 anytime soon, so I can rebase my 8974
patch and send that out? Or would you be interested in me sending you my
8974 and you can include that in your series later?
Yes, will send v3 probably next week. I also have a work in progress
patch for 8974, but don't mind taking yours instead.
BR,
Georgi
