Subject: [PATCH 0/7] arm64: sun50i-h616: Add DMA and SPDIF controllers

From: Chen-Yu Tsai <[email protected]>

Hi everyone,

This series adds DMA and SPDIF controllers for the H616 and H618.
There's also a fix for SPDIF on H6: the controller also has a
receiver that was not correctly modeled.

Patch 1 fixes the binding for the SPDIF controller on the H6 by adding
the RX DMA channel.

Patch 2 adds a compatible string for the H616's SPDIF transmitter to the
binding.

Patch 3 adds a compatible string for the H616's SPDIF transmitter to the
driver.

Patch 4 adds a compatible string for the H616's DMA controller.

Patch 5 adds the RX DMA channel to the SPDIF controller on the H6.

Patch 6 adds a device node for the H616's DMA controller.

Patch 7 adds a device node for the H616's SPDIF controller.


This was tested on the Orange Pi Zero 3 with SPI flash transfers and
SPDIF audio output. The H6 SPDIF change is superficial as the driver
does not support receiving / capturing an audio stream.

Please have a look. I expect the first three patches to go through the
ASoC tree, the fourth patch to either go through the DMA tree, or
through the sunxi tree with an Ack, and the last three through the sunxi
tree.


Thanks
ChenYu

Subject: [PATCH 3/7] ASoC: sunxi: sun4i-spdif: Add support for Allwinner H616

From: Chen-Yu Tsai <[email protected]>

The SPDIF hardware block found in the H616 SoC has the same layout as
the one found in the H6 SoC, except that it is missing the receiver
side.

Since the driver currently only supports the transmit function, support
for the H616 is identical to what is currently done for the H6.

Subject: [PATCH 5/7] arm64: dts: allwinner: h6: Add RX DMA channel for SPDIF

From: Chen-Yu Tsai <[email protected]>

The SPDIF hardware found on the H6 supports both transmit and receive
functions. However it is missing the RX DMA channel.

Add the SPDIF hardware block's RX DMA channel. Also remove the
by-default pinmux, since the end device can choose to implement
either or both functionalities.

Compared the details against the manual, the clock driver, and the
binding, they match:

I compared the OWA manual sections of the H6 and the H616 manuals, and
can confirm that indeed the H616 is the same as the H6, minus the RX
part:

This should include the A100, to cover 34 bits of address space, see
the binding patch comment.

I compared those bits against the manual and the clock driver: they are
correct.

The manual mentions "S_TWI0" using port48, so should we add dma
properties to the r_i2c node as well?

I compared all the other port numbers against the manual, they match.
