[PATCH v4 00/14] r8a7793, gose: Add audio support to device tree

[PATCH v4 00/14] r8a7793, gose: Add audio support to device tree

[Simon Horman]

Hi,

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

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 appreciate
some assistance there.

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-20160111-v4.4 and
has no other dependencies that I am aware of.

Changes between v3 and v4
* Use GIC_SPI in interrupt properties

Changes between v2 and v3
* Minor changelog tweaks

Changes since v1 and v2:
* Dropped RFC designation
* Dropped i2c patches: they have been posted and partially merged separately
* Dropped MIX/CTU support pending more work on that feature
* Enable Audio DMAC peri peri via sound driver
* Other changes noted in per-patch changelogs

[PATCH] ARM: shmobile: armadillo800eva dts: Correct extal1 frequency to 24 MHz

[Geert Uytterhoeven]

On r8a7740/armadillo, actual clock rates are ca. 4% lower than reported
by /sys/kernel/debug/clk/clk_summary. Correct the extal1 frequency from
25 MHz to 24 MHz to fix this.

This matches the Armadillo-800 EVA Product Manual, which claims the main
crystal runs at 24 MHz, and the old legacy/reference board code.

Ping? I think we want this applied to -stable and -ltsi, too.

Sorry for letting this slip through the cracks.

I have queued up the following as a fix for v4.5.

From: Geert Uytterhoeven <geert+renesas@glider.be>
Subject: [PATCH] ARM: dts: armadillo800eva Correct extal1 frequency to 24 MHz

On r8a7740/armadillo, actual clock rates are ca. 4% lower than reported
by /sys/kernel/debug/clk/clk_summary. Correct the extal1 frequency from
25 MHz to 24 MHz to fix this.

This matches the Armadillo-800 EVA Product Manual, which claims the main
crystal runs at 24 MHz, and the old legacy/reference board code.

audio_clk_a/b/c are required for R-Car sound.
