[PATCH 0/5] ARM: tegra: Enable SLINK controller driver

[PATCH 0/5] ARM: tegra: Enable SLINK controller driver

[Laxman Dewangan]

This series modify the dts file to add the slink addresses,
make entry of slink in clock tables, defines SLINK addressed,
enable slink controller in Tegra30 based platform cardhu.

Laxman Dewangan (5):
  ARM: tegra: Add slink controller base address
  ARM: tegra: dts: add slink controller dt entry
  ARM: tegra: fix clock entry of slink controller
  ARM: tegra: dts: cardhu: enable SLINK4
  ARM: tegra: config: enable spi driver for Tegra SLINK controller

Lets not add anything to iomap.h; we're trying to remove it. Instead,
just put the raw address in the AUXDATA; I assume that's the only place
these defines end up being used...

I thought the common DT DMA bindings were going to be in 3.7, and hence
we could just use them here rather than inventing another custom
property for this purpose?

The patch subject isn't entirely accurate here; this patch isn't just
about fixing clock entries.

Here, can't we just use the existing device names in the clock files...

So we can completely drop the changes to these two files:

The device names will hopefully be irrelevant once we're able to use
DT-based clock lookups.

Adding Vinod here.

I looked the dma devicetree bingind document and did not found the 
generic binding name. Howvere, for arm-pl330.txt, it is explained as
Example:

         pdma0: pdma@12680000 {
                 compatible = "arm,pl330", "arm,primecell";
                 reg = <0x12680000 0x1000>;
                 interrupts = <99>;
         };

Client drivers (device nodes requiring dma transfers from dev-to-mem or
mem-to-dev) should specify the DMA channel numbers using a two-value pair
as shown below.

   [property name]  = <[phandle of the dma controller] [dma request id]>;

       where 'dma request id' is the dma request number which is connected
       to the client controller. The 'property name' is recommended to be
       of the form <name>-dma-channel.

   Example:  tx-dma-channel = <&pdma0 12>;


So here I can also add the name like same.

Vinod,
Do you see any issue in follow the above mechanism for Tegra dma client 
driver?

Thanks,
Laxman

       to the client controller. The 'property name' is recommended to be
       of the form <name>-dma-channel.

   Example:  tx-dma-channel = <&pdma0 12>;


So here I can also add the name like same.

Vinod,
Do you see any issue in follow the above mechanism for Tegra dma client 
driver?

Thanks,
Laxman

I want to name the driver as spi-tegra-slink. When we add the sflash spi 
driver for tegra20, the driver name will be spi-tegra-sflash.
Also current name is "spi_tegra" I do not want to name with "_". So it 
is require to convert as "-".

Agree, but currently we can add this to have progress.

That's not the generic bindings. I guess they didn't get merged then. I
guess we can continue with custom bindings until they are.

The driver name is whatever you put into the driver file. The AUXDATA
only affects the device name. There should be no conflict with the
"sflash" driver, since that clock is set up to expect driver name "spi"
which doesn't conflict with "spi_tegra.*".

So, there's really no point in churning the clock names any more,
especially since it's temporary. If you feel strongly about this, the
best thing to do is help push Tegra's support of DT clock bindings forward.

Yes they are in topic topic/dmaengine_dt in my tree. Will be merged once
we sort out slave apis.
