[PATCH v2 00/12] Add StarFive JHB100 syscon modules

[Changhuang Liang]

StarFive JHB100 has many syscon modules, as listed below:
- pcieep0_ecsr_syscon	(PCIe endpoint 0 externel syscon)
- pcieep1_ecsr_syscon
- host0_syscon		(Host0 syscon)
- host1_syscon
- husb0_syscon		(Host USB 0 syscon)
- husb1_syscon
- husbd0_syscon		(Host USB device 0 syscon)
- husbd1_syscon
- husbcmn_syscon	(Host USB common)
- gpu0_syscon		(GPU0 syscon)
- gpu1_syscon
- b2h_syscon		(BMC to Host syscon)
- h2b_syscon		(Host to BMC syscon)
- vout_syscon		(Video output syscon)
- pcierp_ecsr_syscon	(PCIe root port externel syscon)
- pcierp_syscon		(PCIe root port syscon)
- usb_syscon
- npu_syscon
- per0_syscon		(Peripheral 0 syscon)
- per1_syscon
- per2_syscon
- per3_syscon
- sys0_syscon		(System 0 syscon)
- sys1_syscon
- sys2_syscon
- strap_syscon

Some syscon modules contain PLL, reset, and socinfo nodes
This series will add these syscon modules, as well as the
nodes under them.

-PATCH 1:	syscon binging
-PATCH 2-7:	syscon PLL driver
-PATCH 8-10:	syscon reset driver
-PATCH 11:	syscon socinfo driver
-PATCH 12:	syscon device tree

This series depends on the series:
