      dmaengine: bcm-sba-raid: fix Kconfig dependencies · 58d96125
      Arnd Bergmann authored 
      The new driver requires both mailbox and raid support for compile
testing:

drivers/dma/built-in.o: In function `sba_remove':
edma.c:(.text+0x4414): undefined reference to `mbox_free_channel'
drivers/dma/built-in.o: In function `sba_issue_pending':
edma.c:(.text+0x46cc): undefined reference to `mbox_send_message'
drivers/dma/built-in.o: In function `sba_probe':
edma.c:(.text+0x4e60): undefined reference to `mbox_request_channel'
edma.c:(.text+0x5038): undefined reference to `mbox_free_channel'
drivers/dma/built-in.o: In function `sba_tx_status':
edma.c:(.text+0x5210): undefined reference to `mbox_client_peek_data'

drivers/dma/built-in.o: In function `sba_prep_dma_pq_req':
edma.c:(.text+0x5784): undefined reference to `raid6_gflog'
edma.c:(.text+0x5798): undefined reference to `raid6_gflog'

This rearranges the Kconfig dependencies accordingly.

      dmaengine: tegra210-adma: convert TEGRA210_ADMA from bool to tristate · 3ed16793
      Paul Gortmaker authored 
      
This driver currently uses modular infrastructure but is controlled
by a bool Kconfig.

There is a general consensus from the DMA reviewers and maintainers
that "if it can be modular, it should be modular" in order to keep
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!
  ERROR: "pm_clk_create" [drivers/dma/tegra210-adma.ko] undefined!
  ERROR: "pm_clk_destroy" [drivers/dma/tegra210-adma.ko] undefined!
  ERROR: "pm_clk_suspend" [drivers/dma/tegra210-adma.ko] undefined!
  ERROR: "pm_clk_resume" [drivers/dma/tegra210-adma.ko] undefined!

These were added as exports in the v4.8-rc1 merge window.

      dmaengine: vdma: Add 64 bit addressing support to the driver · b72db400
      Kedareswara rao Appana authored 
      
This VDMA  is a soft ip, which can be programmed to support
32 bit addressing or greater than 32 bit addressing.

When the VDMA ip is configured for 32 bit address space
the buffer address is specified by a single register
(0x5C for MM2S and 0xAC for S2MM channel).

When the  VDMA core is configured for an address space greater
than 32 then each buffer address is specified by a combination of
two registers.

The first register specifies the LSB 32 bits of address,
while the next register specifies the MSB 32 bits of address.

For example, 5Ch will specify the LSB 32 bits while 60h will
specify the MSB 32 bits of the first start address.
So we need to program two registers at a time.

This patch adds the 64 bit addressing support to the vdma driver.

      ASoC: samsung: pass filter function as pointer · 9bdca822
      Arnd Bergmann authored 
      As we are now passing the filter data as pointers to the drivers,
we can take the final step and also pass the filter function the
same way. I'm keeping this change separate, as there it's less
obvious that this is a net win.

Upsides of this are:

- The ASoC drivers are completely independent from the DMA engine
  implementation, which simplifies the Kconfig logic and in theory
  allows the same sound drivers to be built in a kernel that supports
  different kinds of dmaengine drivers.

- Consistency with other subsystems and drivers

On the other hand, we have a few downsides:

- The s3c24xx-dma driver now needs to be built-in for the ac97 platform
  device to be instantiated on s3c2440.

- samsung_dmaengine_pcm_config cannot be marked 'const' any more
  because the filter function pointer needs to be set at runtime.
  This is safe as long we don't have multiple different DMA engines
  in thet same system at runtime, but is nonetheless ugly.
