There is a Vivante GC1000 V5037 in LS2K1000 and LS7A1000,
the gpu is a PCI device and it have 2D and 3D in the same core.
Therefore, this patch try to provide PCI device driver wrapper
for it by mimic the platform counterpart.
LS7A1000 is a bridge chip, this bridge chip typically use
integrated,
named lsdc. By using KMS-RO framework, lsdc and gc1000 made a
compatible pair.

encoders should works simply by inherit from this.

Hi,
There's only one exclusive slot, and we must not break the ordering.
Adding a new exclusive fence drops all previous fences from the
dma_resv. To avoid violating the signalling order we err on the side of
over-synchronizing by waiting for the existing fences, even if
userspace asked us to
This patch add a function (etnaviv_gpu_clk_get()) which is separated
from the etnaviv_gpu_platform_probe() function.

This patch separate the code related to the platform device creation
so that it can be reuse by other function.
An immediate benefit is we need call of_node_put() only once in the

There is a display controller in loongson's LS2K1000 SoC and LS7A1000
bridge chip, the display controller is a PCI device in those chips. It
has two display pipes but with only one hardware cursor. Each way has
a DVO interface which provide RGB888 signals, vertical & horizontal
synchronisations,
module, either general purpose GPIO emulated i2c or hardware
i2c adapter.
