[PATCH/RFC 00/19] r8a7793, gose: Add i2c and audio support to device tree

[PATCH/RFC 00/19] r8a7793, gose: Add i2c and audio support to device tree

[Simon Horman]

Hi,

this series adds support to r8a7793 and gose device trees for:
* i2c and iic
* rcar sound: first in PIO mode then using DMA

i2c support is a pre-requisite for rcar sound support.

Unfortunately there appears to be some problem with DMA
for rcar sound that I have been unable to track down. On booting I see:

rcar_sound ec500000.sound: dma allocate failed
rcar_sound ec500000.sound: ssi[0] fallback to PIO mode
rcar_sound ec500000.sound: ssi[1] fallback to PIO mode
rcar_sound ec500000.sound: probed

I would appreciate any insights regarding the above.

I have been unable to test if audio works (in PIO mode) as I
do not have physical access to a gose board. I would appreaciate
some assistance there too.

This work is based heavily on the work of others for the r8a7791 and
koelsch.  as noted in the changelogs of individual patches.

This series is based on renesas-devel-20151211-v4.4-rc4.

[PATCH/RFC 04/19] ARM: shmobile: r8a7793: add iic(b) to device tree

[Simon Horman]

Instantiate iic(b) controllers in r8a7793 device tree.

Based on similar work for the r8a7791 and r8a7791 by Wolfram Sang.

The out-of order aliasing of iic to i2c is as per the documentation.
This differs from the scheme in use in the dtsi files for
other R-Car SoCs.

It would be nice to harmonise this somehow but I'm unsure of the backwards
compatibility issues.

For reference those aliases are:

* r8a7790:
  - i2c0 = &i2c0;
  - i2c1 = &i2c1;
  - i2c2 = &i2c2;
  - i2c3 = &i2c3;
  - i2c4 = &iic0;
  - i2c5 = &iic1;
  - i2c6 = &iic2;
  - i2c7 = &iic3;

  Notes:
  - The documentation does not make note of i2c aliases for iic
    (v1.02, table 12.2.1)
  - i2c4 and i2c5 are not present on this SoC

* r8a7791:
  - i2c0 = &i2c0;
  - i2c1 = &i2c1;
  - i2c2 = &i2c2;
  - i2c3 = &i2c3;
  - i2c4 = &i2c4;
  - i2c5 = &i2c5;
  - i2c6 = &i2c6;
  - i2c7 = &i2c7;
  - i2c8 = &i2c8;

  Notes:
  - i2c is used in place of iic and it is my understanding that
    i2c6 is iic0, i2c7 is iic1 and i2c8 is iic3.
  - iic3 is not present on this SoC
  - Documentation makes note of (v1.02, table 12.2.1).
    They are the same as those used in this patch for the r8a7793

* r8a7794:
  - i2c0 = &i2c0;
  - i2c1 = &i2c1;
  - i2c2 = &i2c2;
  - i2c3 = &i2c3;
  - i2c4 = &i2c4;
  - i2c5 = &i2c5;

  Notes:
  - iic0 and iic1 nodes not present in mainline but are present on this SoC
  - Documentation makes note of the following aliases (v1.02, table 12.2.1)
    - iic6 = &iic0
    - iic8 = &iic1
  - iic2 and iic3 are not present on this SoC

[PATCH/RFC 14/19] ARM: shmobile: gose: enable sound DMA support via BUSIF in device tree

[Simon Horman]

Enable DMA transfer to/from SSIU in gose/r8a7791 device tree.

     DMA
[MEM] -> [SSIU] -> [SSI]

     DMA
[MEM] <- [SSIU] <- [SSI]

[PATCH/RFC 15/19] ARM: shmobile: gose: enable sound DMA support via SRC in device tree

[Simon Horman]

Enable DMA transfer to/from SRC in r8a7793/gose device tree.

     DMA      DMApp
[MEM] -> [SRC] -> [SSIU] -> [SSI]

     DMA      DMApp
[MEM] <- [SRC] <- [SSIU] <- [SSI]

Current sound driver is supporting
SSI/SRC random connection.
So, this patch is tring
SSI0 -> SRC2
SSI1 <- SRC3

This series looks fine, when comparing the resulting DTS of
r8a7793 and r8a7791, and taking into account the i2c/iic alias differences.

Except for the missing audmapp.

You can add my

My main motivation is that it follow the pattern already used
for other clocks in the same file. I believe all the Renesas ARM32
DTS/DTSI files are currently using mssr. Perhaps we should
come up with a plan to migrate some or all of them to mstp.

Thanks! I have added peri peri and Audio appears to now work with DMA
(though I only have remote access to the gose board so I can't verify
 audio actually works).

I copied this value from r8a7791.dtsi.

Looking at the schematic for gose (v100), koelsch (rev024) and porter (v300)
I see the following "R1EX24002ATAS0G#U0". Shall we update r8a7791 and
this patch to "renesas,24002" or leave things as is?

I wouldn't like to update the at24 driver with all namings from all
vendors for chips which in large cases are simple 24c02 devices.

So, if Sergei insists on the change, I'd propose

	compatible = "renesas,24002", "24c02";

to keep things sane.

"renesas,r1ex24002"?

I don't think the "A" is relevant (<= 64 is A, >= 128 is B).

Thanks.

It seems to me that we have some consensus around:

	compatible = "renesas,r1ex24002", "24c02";

Should this be added to Documentation/devicetree/bindings/eeprom/eeprom.txt ?
Or documented elsewhere?

I believe that as well as any documentation and update of this patch-set
that r8a7791-koelsch.dts will also need to be updated. I plan to do so.

Thinking again, "generic,24c02" or "generic-24c02" could also be an
option.

Probably we need a DT maintainers advice here? I don't mind vendor
specific compatibles being documented, but I'm reluctant to add all
these compatibles for the myriads of I2C eeproms to the at24 driver. 99%
are covered by the generic case.

I'd rather use some vendor string in addition to 24c02. Isn't this originally
an Atmel part? In that case, using "atmel,24c02" as the most generic string
would be appropriate, and IIRC the i2c framework will just match that with
the "24c02" entry in the i2c_device_id list.

I'd rather use some vendor string in addition to 24c02. Isn't this originally
an Atmel part? In that case, using "atmel,24c02" as the most generic string
would be appropriate, and IIRC the i2c framework will just match that with
the "24c02" entry in the i2c_device_id list.

Yeah, the at24 driver is named after Atmel chips AFAIR. Having "atmel,*"
as the generic fallback sounds like a good solution to me, too.

True, although this behaviour is often complained about. There have been
attempts to make i2c/spi behave like the rest of the DT world and to
deprecate the current way. It didn't happen because of lots gory details,
however :/

My reading of the above is that we are currently leaning towards:

	compatible = "renesas,r1ex24002", "atmel,24c02";

And we are unsure what to do about the documentation.
