[v4,0/4] drivers: clk: Add ZynqMP clock driver support

Message

Jolly Shah Sept. 28, 2018, 5:13 p.m. UTC

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.

This patch series is earlier reveiwed as part of FW patchset (https://patchwork.kernel.org/cover/10555405/). 
FW driver from that patchset is merged. This patchset contains only clock driver and is based on top of 
xilinx firmware patch set available in below tree:
https://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc.git/log/?h=next/drivers

v4:
 - Fixed minor review comments received for v3 patchset
 
v3:
 - Added check to pass only valid ioctls for ioctl eemi api
 - Added eemi documentation including ioctl details
