Subject: [PATCH v4 00/28] ARM: Initial Actions Semi S500 and S900 enablement
Hello,
This patch series adds initial support for Actions Semiconductor S500 (ARMv7)
and S900 (ARMv8) SoCs.
v4 refactors the clocksource driver again and fixes power-gating for CPU2/CPU3.
With this v4 I would like to start applying initial patches to my tree for 4.13.
@Actions: Last call for comments on vendor prefix and SoC bindings!
@uCRobotics: Last call for comments on vendor prefix and board bindings!
@LeMaker: Last call for comments on module and board bindings!
Work branch for testing:
https://github.com/afaerber/linux/commits/bg96-next
Booting from U-Boot to initrd is straightforward on both boards:
https://en.opensuse.org/HCL:Guitar
https://en.opensuse.org/HCL:Bubblegum-96
Have a lot of fun!
Cheers,
Andreas
v3 -> v4:
* Revert to hardcoded TIMER0/1 in clocksource (Daniel)
* Make power domains CPU2 and CPU3 always-on
* Clean up SMP vs. PM domains code duplication
* Extend earlycon documentation (Jonathan)
* Update MAINTAINERS with SPS files
v2 -> v3:
* Clocksource fix
* Clocksource cleanups (Daniel)
* Serial cleanups
* Add S500 CPU enable-method
* Add power domain driver
* Rework clocksource for S900 compatibility
v1 -> v2:
* S900 DT fixes (Mark)
* Kconfig name changes (Arnd)
* Bubblegum-96 .dts rename
* Vendor prefix rename
* Minor cleanups
* Add serial driver
* Add MAINTAINERS section
* Use SPDX-License-Identifier in DT (Rob)
* Add clocksource driver
