[Resent with *correct* linux-pm in CC] On the Amlogic Gx SoCs (GXBB, GXL & GXM), the VPU power domain is initialized by the vendor U-Boot code, but running mainline U-boot has been possible on these SoCs. But lacking such init made the system lock at kernel boot.
This patchset adds the Video Processing Unit power domain driver to enable the same power-on and power-down sequences and was designed to allow booting with the power domain already initialized or not. This driver has been tested on : - Odroid-C2 (GXBB) with Vendor and Mainline U-Boot - P212 (GXL) with Vendor and Mainline U-Boot - Khadas Vim (GXL) with Vendor U-Boot - Khadas Vim2 with (GXM) Vendor U-Boot Changes since v1: - fixed bindings compatible string Neil Armstrong (2): soc: amlogic: add Meson GX VPU Domains driver dt-bindings: power: add amlogic meson power domain bindings .../bindings/power/amlogic,meson-gx-pwrc.txt | 61 ++++++ drivers/soc/amlogic/Kconfig | 10 + drivers/soc/amlogic/Makefile | 1 + drivers/soc/amlogic/meson-gx-pwrc-vpu.c | 234 +++++++++++++++++++++ 4 files changed, 306 insertions(+) create mode 100644 Documentation/devicetree/bindings/power/amlogic,meson-gx-pwrc.txt create mode 100644 drivers/soc/amlogic/meson-gx-pwrc-vpu.c -- 2.7.4
