This patch series adds i.MX8QXP clock support which is based
on the clock service provided by SCU firmware.

Note: It depends on SCU driver which has already been merged by Shawn.
So this patch series could go through Shawn's tree as well.

ChangeLog:
v9->v10:
 * a small clean up of PATCH 2
   remove ccm_ipc_handle from headfile as no other users need it now
   and move imx_clk_scu_init() implementation into driver accordingly.
 * a typo fix of Patch 10
v8->v9:
 * add __le32 and __le16 for SCU message structure members as it's little endian
 * use readl_relaxed() as it does not need insert barrier
 * a small code logic improvement suggested by Stephen
v7->v8:
 * add more kernel doc for lpcg and scu clock structures
 * remove one unneccessry reg checking
v6->v7:
 * use struct_size()
 * remove MODULE_ macros
 * add more kernel docs/code comments
 * other small improvements
 * update reviewed-by tags
 * add the missing PATCH 1 in V6
v5->v6:
 * simply the driver a lot by re-orgnizing the driver into a few clock types:
   scu clock (merge scu divider/gate/mux) and scu gpr lock which accessing is
   through SCU protocol and LPCG clock which is directly accessible by CPU.
 * LPCG clock is separate from SCU clock, gpr clock is still not used
   and will be added later.
 * remove old year license as the code is totally rewritten
 * scu mux support will be added later as it's also still not used.
v4->v5:
 Address all Stephen and Sascha's review comments, see details in each patch
v3->v4:
 * scu headfile path update
 * no functionality change
v2->v3:
 * structures/enums name update with imx_sc prefix
 * no functionality change
v1->v2:
 * structure and enums name update
 * api usage update due to api change
 * no functionality change

Hi Stephen,

This series is made against clk-next.
Due to newly added clk-imx7ulp and clk-imx8mq in clk-next,
you may meet apply failure if apply against clk-master branch.

So If you need me to re-generate a patch series against clk-master,
Please let me know. But that may still get an error when merger the
Series Into clk-next, I guess.

Regards
Dong Aisheng
