Spreadtrum is a rapid growing chip vendor providing smart phone total solutions.

Sharkl64 Platform is nominated as a SoC infrastructure that supports 4G/3G/2G
standards based on ARMv8 multiple core architecture.Now we have only one
SoC(SC9836) based on this Platform in developing.

This patchset adds Sharkl64 support in arm64 device tree and the serial driver
of SC9836-UART.

This patchset also has patches which address "sprd" prefix and DT compatible
strings for nodes which appear un-documented.

This version code was tesed on Fast Mode.

This concerns me a bit because fast models are extremely lenient w.r.t.
the management of clocks and regulators. Are you sure you have
everything you need for your UART described?

We use boot-wrapper-aarch64 as the bootloader.

Which version of boot-wrapper-aarch64 are you using?

Upstream does not implement PSCI 0.2, but its --enable-psci option will
inject PSCI 0.1 compatible properties, which leads me to suspect that
your DT is misleading. The boot wrapper should also program CNTFRQ_EL0
correctly regardless.

What do you intend to use on real hardware?

Thanks,
Mark.

Changes from v2:
* Addressed review comments:
	- Added a specific compitible string 'sc9836-uart' for the serial
	- Added a full serial driver
	- Added the property 'clock-frequency' for timer node in dtsi.
	- Replaceed the old macro prefix 'UART_' with 'SPRD_' in the 
	  Spreadtrum serial driver code.
* Revised the name of SoC and board from 'sharkl3' to 'sc9836'
* Used dual-license for DTS files
* Added a menuconfig 'ARCH_SPRD' in arch/arm64/Kconfig

Changes from v1:
* Addressed review comments:
        - Added "sprd" prefix to vendor-prefixes.txt
        - Created serial/sprd-serial.txt and remove the properties for serial-sprd
          from of-serial.txt to it.
        - Renamed of-serial.txt to 8250.txt according to Arnd's review comments
        - Splited and revised .dts for Sharkl64 Platform
        - Changed to PSCI method for cpu power management
        - Revised Kconfig Makefile to match the alphabetical ordering
        - Renamed serial-sprd-earlycon.c to serial-sprd.c
