ea62e2ccbb dmaengine: stm32_mdma: add CONFIG_OF dependency
Without CONFIG_OF we get a build warning:

warning: (STM32_MDMA) selects DMA_OF which has unmet direct dependencies (DMADEVICES && OF)

This adds a dependency on CONFIG_OF. Since this means
we no longer need to select 'DMA_OF', I'm dropping that line
as well.

a4ffb13c89 dmaengine: Add STM32 MDMA driver
This patch adds the driver for the STM32 MDMA controller.

Master Direct memory access (MDMA) is used in order to provide high-speed
data transfer between memory and memory or between peripherals and memory.

MDMA controller provides a master AXI interface for main memory and
peripheral registers access (system access port) and a master AHB
interface only for Cortex-M7 TCM memory access (TCM access port).

MDMA works in conjunction with the standard DMA controllers (DMA1 or DMA2).
It offers up to 64 channels, each dedicated to managing memory access
requests from one of the DMA stream memory buffer or other peripherals
(w/ integrated FIFO).

df7e762db5 dmaengine: Add STM32 DMAMUX driver
This patch implements the STM32 DMAMUX driver.

The DMAMUX request multiplexer allows routing a DMA request line between
the peripherals and the DMA controllers of the product. The routing
function is ensured by a programmable multi-channel DMA request line
multiplexer. Each channel selects a unique DMA request line,
unconditionally or synchronously with events from its DMAMUX
synchronization inputs. The DMAMUX may also be used as a DMA request
generator from programmable events on its input trigger signals

This driver adds support for the Altera / Intel modular Scatter-Gather
Direct Memory Access (mSGDMA) intellectual property (IP) to the Linux
DMAengine subsystem. Currently it supports the following op modes:

- DMA_MEMCPY
- DMA_SG
- DMA_SLAVE

This implementation has been tested on an Altera Cyclone FPGA connected
via PCIe, both on an ARM and an x86 platform.

d762e4f356 dmaengine: Kconfig: Extend the dependency for MXS_DMA
Currently it is not possible to select the mxs dma driver when only
mx6sx or mx7 are selected.

Extend the dependency to allow the mxs dma driver to be built whenever
ARCH_MXS or ARCH_MXC is selected.

This has the benefit to avoid having to add new entries in the
MXS_DMA Kconfig everytime a new i.MX SoC shows up and it also makes
it consistent with the other i.MX DMA engines, such as IMX_DMA and
IMX_SDMA.

While at it, also pass COMPILE_TEST for increasing the build coverage.

1e1cfc7213 dmaengine: pl08x: Add support for Faraday Technology FTDMAC020
After reading the specs for the Faraday Technology FTDMAC020 found
in the Gemini platform, it becomes pretty evident that this is just
another PL08x derivative, and should be handled like such by simply
extending the existing PL08x driver to handle the quirks in this
hardware.

This patch makes memcpy work and has been tested on the Gemini and
also regression-tested on the Nomadik NHK15 using dmatest with
10 threads per channel without a hinch for hours.

I have not implemented slave DMA in those codepaths, because this
device (Gemini) does not use slave DMA, and it seems like devices
using FTDMAC020 for device DMA have a slightly different register
layout so some real hardware is needed to proceed with this. I
left some FIXME etc in the code for this.

I had to do some refactorings of some helper functions, but I have
not split those into separate patches because these refactorings
do not make much sense without the increased complexity of handling
the FTDMAC020.

The DMA test would hang the platform on me on the Gemini after a
few thousand iterations, however after turning of the caches the
problem immediately disappeared and I could run the DMA engine
with 10 threads pers physical channel for days in a row without
a crash. I think there is no problem with the DMA driver: instead
it is something fishy in the FA526 cache handling code that get
pretty heavily exercised by the DMA engine and we need to go and
fix that instead.

 Handling of virtio device resources was improved, vring memory is now

 processor.
 
 The debugfs mechanism for starting and stopping remoteproc instances was

 New drivers for the ST Slimcore and Qualcomm Hexagon DSP as well as

 Finally support for crash recovery in the Qualcomm Wirelss subsystem
 (used for WiFi/BT/FM on a number of platforms) and a number of bug fixes
 and cleanups.

the bzImage size under control for multi platform kernels.

Build tested only.  Also needed some new pm_clk symbols exported
before this commit is applied to tree in order to avoid modpost
errors like:

  ERROR: "pm_clk_add_clk" [drivers/dma/tegra210-adma.ko] undefined!

There are some compilation errors when CONFIG_MMP_TDMA is enabled and
CONFIG_GENERIC_ALLOCATOR is disabled:

drivers/built-in.o: In function `mmp_tdma_prep_dma_cyclic':
mmp_tdma.c:(.text+0x7890e): undefined reference to `gen_pool_dma_alloc'
drivers/built-in.o: In function `mmp_tdma_free_chan_resources':
mmp_tdma.c:(.text+0x78aca): undefined reference to `gen_pool_free'
drivers/built-in.o: In function `mmp_tdma_probe':
mmp_tdma.c:(.text+0x78ea8): undefined reference to `of_gen_pool_get'

This commit fix this problem by selecting GENERIC_ALLOCATOR when
CONFIG_MMP_TDMA is enabled.

6b4cd727ea dmaengine: st_fdma: Add STMicroelectronics FDMA engine driver support
This patch adds support for the Flexible Direct Memory Access (FDMA) core
driver. The FDMA is a slim core CPU with a dedicated firmware.
It is a general purpose DMA controller capable of supporting 16
independent DMA channels. Data moves maybe from memory to memory
or between memory and paced latency critical real time targets and it
is found on al STi based chipsets.

To get more coverage, enable COMPILE_TEST for this driver.
When compile testing eDMA or omap-dma, select also the ti-dma-crossbar so
it is also covered by the compile testing.
