Add driver for the clk controller which found in Meson AXG SoC

  Note, we deliberately create a seperate source file for the Meson AXG
series, instead of sharing code with previous GXBB/GXL - the file axg.c
It would help us maintaining the code more easily.

Changes since v6 [6]:
 - move the spinlock' change patch as first as the dependency
 - drop unnecessary flag CLK_GET_RATE_NOCACHE, CLK_SET_RATE_NO_REPARENT
 - drop useless comments
 - fix checkpatch issue, over 80 characters 

Changes since v5 [5]:
 - add Rob's Ack for patch 2, add Neil's Ack for patch 3
 - include spinlock' name change patch, patch 4
 - include uart_ao clock DTS patch

Changes since v4 [4]:
 - use devm_ioremap instead of devm_ioremap_resource
 - rename DT node using generic name 'bus'

Changes since v3 [3]:
 - separate dt-bindings header file
 - adjust license note as standard way
 - replace of_iomap with platform/devm API
 - add Rob's Ack to Patch 1,4

Changes since v2 [2]:
 - drop register offset calculation
 - update dt-bindings for new compatible variant

Changes since v1 [1]:
 - rework register definion, use '(offset << 2)' to better match
   the description from data sheet
 - drop "#include dt-bindings/clock/gxbb-aoclkc.h" from dts
 - rebase code to v4.15-rc1

Make the spinlock more specific, so better for lockdep
debugging and ctags/grep.

Try to add Hiubus DT info, and also enable clock DT info
for the Amlogic's Meson-AXG SoC.

Switch the uart_ao pclk to CLK81 since the clock driver is ready.
Also move the clock info to the board.dts instead in the soc.dtsi.

Kevin, 

I took the first 4 patches through clk-meson. I left the last 2 for you.

I have applied the DT bindings update separately.
Let me know if you have dependency on these new bindings and need a tag.

Cheers

thanks for taking care of this..

I think it's a good idea to make a tag, if peripheral driver request
clock, then the DT part patch will need
include/dt-bindings/clock/axg-clkc.h to build successfully.

Same comment as for ethmac, is it really wise ?
Isn't the clock setup the same for the axg family ?

HI Jerome:
yes, should be same for AXG family


HI Kevin:
could you take the patch [5/6]? then I just need to resend for this one

Yes, I will need a tag on the headers since both the "switch uart_ao"
patch and a subsequent patch to add DT for SPICC are using new clock
IDs.
