Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver updates from Olof Johansson:
"This branch contains platform-related driver updates for ARM and ARM64.
Among them:
- Reset driver updates:
+ New API for dealing with arrays of resets
+ Make unimplemented {de,}assert return success on shared resets
+ MSDKv1 driver
+ Removal of obsolete Gemini reset driver
+ Misc updates for sunxi and Uniphier
- SoC drivers:
+ Platform SoC driver registration on Tegra
+ Shuffle of Qualcomm drivers into a submenu
+ Allwinner A64 support for SRAM
+ Renesas R-Car R3 support
+ Power domains for Rockchip RK3366
- Misc updates and smaller fixes for TEE and memory driver
subsystems"
