This patchset is adding communication layer with firmware and clock
driver who uses those APIs to communicate with PMU.
Firmware driver provides an interface to firmware APIs.Interface APIs
can be used by any driver to communicate to PMUFW(Platform Management
Unit). All requests go through ATF.
quoted
This patchset adds CCF compliant clock driver for ZynqMP.Clock driver
queries supported clock information from firmware and regiters pll and output
clocks with CCF.

v5:
 - Added ATF version check support
 - Updated some functions to be static
 - Minor function name corrections

v4:
 - Changed clock setrate/getrate API prototype to support 64 bit rate
 - Defined macros for get_node_status return values
 - Moved DT node as a child of firmware
 - Changed debugfs APIs to return data to debugfs buffer instead of
dumping to kernel log
 - Minor changes to incorporate other review comments from v3 patch
series

v3:
 - added some fixes to firmware-ggs.c
 - updated pinmux get/set function argument names to specify function
id instead of node id
 - added new pinctrl query macros

It looks pretty calm over the last several series that's why when I get an answer
from Stephen or Mike I will take this series via my tree and arm-soc tree.

I have applied 01-08 here
 https://github.com/Xilinx/linux-xlnx/commits/zynqmp/soc

Thanks,
Michal

Thanks for merging the patches. 
By mistake I added ?Reviewed-by: Stephen Boyd sboyd at kernel.org? for firmware bindings (Patch01).  Stephen had reviewed clock bindings only.  Please suggest if I should send a new version with that fix.
I have fixed that in my branch and I have asked Shephen to look at clk
over chat.

Thanks,
Michal
