Rockchip RGA is a separate 2D raster graphic acceleration unit. It
accelerates 2D graphics operations, such as point/line drawing, image
scaling, rotation, BitBLT, alpha blending and image blur/sharpness
The drvier is mostly based on s5p-g2d v4l2 m2m driver
And supports various operations from the rendering pipeline.
- copy
- fast solid color fill
- rotation
- flip
- alpha blending
The code in rga-hw.c is used to configure regs accroding to operations
The code in rga-buf.c is used to create (1-Level)mmu table for RGA
The tables is stored in a list, and be removed when buffer is cleanup

Those driver will never be used at rockchip platform and features
may not be widely used is disabled this time.
1. Ethernet drivers for the other platforms.
2. Network features which are used for IPSec(VPN), bandwidth
control or network management.
3. Disable strange input devices.
4. Disable those filesystems only used for special purposes.
5. Some misc devices only used in a few situations.
6. Disable all the security model except the unix default.

1. rename mipi_dsi to dsi0
2. add some properties, such as dual-channel
3. add dsi1 node

As the documentation for readx_poll_timeout says, we want to use the
specialized macro for readl rather than using the generic version
directly.

rk3288 and rk3288w use different compatible string, so add
"rockchip,rk3288w" to support rk3288w.

rk3288 and rk3288w use the same dts which includes no relinquish
port quirk, however rk3288w ohci can work well, so we need to add
an additional condition to disable ohci only for rk3288.

rk3288 ohci doesn't actually work on hardware, so we

rk3288 and rk3288w have an ohci controller, although rk3288
ohci doesn't actually work on hardware, but rk3288w ohci can
work well, so we need to add usb ohci node in dts, and then
add a quirk in ohci driver to disable ohci for rk3288.
