VT6420 seems to have the same hotplug capability as VT6421.
However, enabling hotplug needs to expose SCR registers which can cause
problems. It works for me but might break elsewhere. So add a module
parameter vt6420_hotplug to enable this feature.

Hi,
This serie brings A10 (sun4i) and A20 (sun7i) SoCs into the
sunxi-ng world.
As mentioned in sun5i conversion, this is pretty much standard
stuff as all the required clocks were already implemented in
the sunxi-ng framework.
Changes from v3:
- Add support for fixed post-divider support for

Hi All,
Here is v2 patch-series adding drivers for Intel FPGA devices.
The Intel FPGA driver provides interfaces for userspace applications to
configure, enumerate, open, and access FPGA accelerators on platforms
equipped with Intel(R) PCIe based FPGA solutions and enables system
level
During FPGA device (e.g PCI-based) discovery, platform devices are
registered for different FPGA function units. But the device node path
isn't quite friendly to applications.
Consider this case, applications want to access child device's sysfs file
for some information.

DMA memory regions are required for Accelerated Function Unit (AFU) usage.
These two ioctls allow user space applications to map user memory regions
for dma, and unmap them after use. Iova is returned from driver to user
space application via FPGA_PORT_DMA_MAP ioctl. Application needs to unmap
it
On Intel FPGA devices, the Accelerated Function Unit (AFU), can be
reprogrammed for different functions. It connects to the FPGA
infrastructure("blue bistream") via a Port. Port CSRs are implemented
separately from the AFU CSRs to provide control and status of the Port.
Once valid green bitstream
FPGA_GET_API_VERSION and FPGA_CHECK_EXTENSION ioctls are common ones which
need to be supported by all feature devices drivers including FME and AFU.
Userspace application can use these ioctl interfaces to get the API info
and check if specific extension is supported or not in current driver.
The header register set is always present for the Port/AFU, it is mainly
for capability, control and status of the ports that AFU connected to.
This patch implements header sub feature support. Below user interfaces
are created by this patch.

User Accelerated Function Unit sub feature exposes the MMIO region of

The FPGA Management Engine (FME) provides power, thermal management,
performance counters, partial reconfiguration and other functions. For each
function, it is packaged into a private feature linked to the FME feature

From: Kang Luwei
Partial Reconfiguration (PR) is the most important function for FME. It
allows reconfiguration for given Port/Accelerated Function Unit (AFU).
It creates platform devices for fpga-mgr, fpga-regions and fpga-bridges,
and invokes fpga-region's interface (fpga_region_program_fpga)
For FPGA Management Engine (FME), it requires fpga_for_each_port callback
for actions on ports, so export this function from PCIe driver by adding
the callback to the platform data.
