[PATCH 0/4] ARM: sun8i: a83t: Add support for I2S and I2C

[PATCH 0/4] ARM: sun8i: a83t: Add support for I2S and I2C

[Chen-Yu Tsai]

Hi everyone,

This series adds support for I2S and I2C on the Allwinner A83T SoC.
The I2S controllers are similar to the ones found on the A31. However
the TX FIFO and interrupt status registers were swapped around. This
seems to be a recurring theme for the audio related hardware blocks.

Patch 1 adds support for the A83T variant with a compatible string
and associated quirks structure.

Patch 2 adds device nodes and default pinmux settings for the I2S
controllers.

Patch 3 adds device nodes and default pinmux settings for the I2C
controllers.

Patch 4 is an example of a PCM5122 codec tied to I2C2 and I2S1 over
the GPIO header of the Banana Pi M3. This patch should not be merged.

Please have a look.

Regards
ChenYu

[PATCH 1/4] ASoC: sun4i-i2s: Add support for A83T

[Chen-Yu Tsai]

The I2S controller in the A83T is mostly compatible with the one found
in earlier SoCs such as the A20 and A31. While the documents publicly
available for the A83T do not cover this hardware, the officially
released BSP kernel does have register definitions for it. These were
matched against the A20 user manual. The only difference is the TX FIFO
and interrupt status registers have been swapped around, like what we
have seen with the SPDIF controller.

This patch adds support for this hardware.

[PATCH 2/4] ARM: dts: sun8i: a83t: Add I2S controller device nodes

[Chen-Yu Tsai]

The A83T has 3 I2S controllers. The first is multiplexed with the TDM
controller. The pins are generally connected to the codec side of the
AXP81x PMIC/codec/RTC chip. The second is free for other uses. The
third only supports output, and is connected internally to the HDMI
controller for HDMI audio output.

This patch adds device nodes for the controllers, and a default pinmux
setting for the second controller.

[PATCH 3/4] ARM: dts: sun8i: a83t: Add I2C device nodes and pinmux settings

[Chen-Yu Tsai]

The A83T has 3 I2C controllers under the standard bus. There is one
more in the R_ block section. The pin functions for the 3 controllers
are on PH 0~6. I2C2 can also be used on pins PE14 and PE15, but these
pins can also mux the CSI (camera sensor interface) controller's
embedded I2C controller. The latter seems to be preferred in the
reference designs for I2C camera sensor access, freeing I2C2 for other
uses.

This patch adds device nodes for the three standard I2C controllers,
as well as pinmux settings for the PH pins. For I2C0 and I2C1, since
they only have one possible setting, just set them by default.

[PATCH 4/4] [DO NOT MERGE] ARM: dts: sun8i: a83t: bpi-m3: Enable PCM5122 codec with I2S1

[Chen-Yu Tsai]

This patch enables a PiFi DAC+ V2.0, which is a PCM5122-based audio
output DAC add-on board for the Raspberry Pi B+ and later, connected
to the GPIO header of the Bananapi M3 via jumper cables. The power,
ground, and I2C pins are in the same position, but the I2S ones are
not.

The I2C controller used is I2C2, while the I2S controller is I2S1.

I'm sure I've asked this before, and IIRC the answer was yes: The I2C
controllers available on the GPIO header all have proper, always-on,
external pull-ups. Does that mean we can enable them by default, seeing
as they are likely intended to be used this way (as I2C pins)?

I think we have a few boards where either I2C or UARTs on the GPIO
header are enabled by default.

compatible first.

The consensus we reached that we would fill the nodes, but leave them
disabled.

In this particular case, I guess it would help for the i2c controller,
but not for the i2s one.

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Subject: [PATCH] ASoC: sun4i-i2s: Add support for A83T

The I2S controller in the A83T is mostly compatible with the one found
in earlier SoCs such as the A20 and A31. While the documents publicly
available for the A83T do not cover this hardware, the officially
released BSP kernel does have register definitions for it. These were
matched against the A20 user manual. The only difference is the TX FIFO
and interrupt status registers have been swapped around, like what we
have seen with the SPDIF controller.

This patch adds support for this hardware.
