VOP can be used in dual OS by config the following property at dts:
example:
linux dts:
&vop {
iommus = <&vop_mmu1>;
rockchip,shared-mode-axi-id = <1>;
rockchip,shared-mode = <(ROCKCHIP_VOP2_SHARED_MODE_PRIMARY)>;
rockchip,shared-mode-vp-mask = <(1 << ROCKCHIP_VOP_VP2)>;
rockchip,shared-mode-plane-mask = <(1 << ROCKCHIP_VOP2_ESMART2 | 1 << ROCKCHIP_VOP2_ESMART3)>;
};
android dts:
&vop {
iommus = <&vop_mmu>;
rockchip,shared-mode-axi-id = <0>;
rockchip,shared-mode = <(ROCKCHIP_VOP2_SHARED_MODE_SECONDARY)>;
rockchip,shared-mode-vp-mask = <(1 << ROCKCHIP_VOP_VP0 | 1 << ROCKCHIP_VOP_VP1)>;
rockchip,shared-mode-plane-mask = <(1 << ROCKCHIP_VOP2_CLUSTER0 | 1 << ROCKCHIP_VOP2_CLUSTER1 |
1 << ROCKCHIP_VOP2_ESMART0 | 1 <<ROCKCHIP_VOP2_ESMART1)>;
};

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
