ASoC: simple-card-utils: fix graph_util_is_ports0() for DT overlays

2026-03-25T10:08:27+00:00

[ Upstream commit 4185b95f8a42d92d68c49289b4644546b51e252b ] graph_util_is_ports0() identifies DPCM front-end (ports@0) vs back-end (ports@1) by calling of_get_child_by_name() to find the first "ports" child and comparing pointers. This relies on child iteration order matching DTS source order. When the DPCM topology comes from a DT overlay, __of_attach_node() inserts new children at the head of the sibling list, reversing the order. of_get_child_by_name() then returns ports@1 instead of ports@0, causing all front-end links to be classified as back-ends. The card registers with no PCM devices. Fix this by matching the unit address directly from the node name instead of relying on sibling order.

ASoC: simple-card-utils: use __free(device_node) for device node

2026-03-25T10:08:27+00:00

[ Upstream commit 419d1918105e5d9926ab02f1f834bb416dc76f65 ] simple-card-utils handles many type of device_node, thus need to use of_node_put() in many place. Let's use __free(device_node) and avoid it.

ASoC: simple-card-utils: Check device node before overwrite direction

2026-02-11T12:40:22+00:00

[ Upstream commit 22a507d7680f2c3499c133f6384349f62f916176 ] Even the device node don't exist, the graph_util_parse_link_direction() will overwrite the playback_only and capture_only to be zero. Which cause the playback_only and capture_only are not correct, so check device node exist or not before update the value.

ASoC: simple-card-utils: Fix pointer check in graph_util_parse_link_direction

[ Upstream commit 3cc393d2232ec770b5f79bf0673d67702a3536c3 ] Actually check if the passed pointers are valid, before writing to them. This also fixes a USBAN warning: UBSAN: invalid-load in ../sound/soc/fsl/imx-card.c:687:25 load of value 255 is not a valid value for type '_Bool' This is because playback_only is uninitialized and is not written to, as the playback-only property is absent.

ASoC: audio-graph-card2: Purge absent supplies for device tree nodes

2024-11-11T11:47:04+00:00

The audio graph card doesn't mark its subnodes such as multi {}, dpcm {} and c2c {} as not requiring any suppliers. This causes a hang as Linux waits for these phantom suppliers to show up on boot. Make it clear these nodes have no suppliers. Example error message: [ 15.208558] platform 2034000.i2s: deferred probe pending: platform: wait for supplier /sound/multi [ 15.208584] platform sound: deferred probe pending: asoc-audio-graph-card2: parse error Signed-off-by: John Watts Acked-by: Kuninori Morimoto Link: https://patch.msgid.link/20241108-graph_dt_fix-v1-1-173e2f9603d6@jookia.org Signed-off-by: Mark Brown

ASoC: Switch back to struct platform_driver::remove()

2024-09-09T17:26:49+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all drivers below sound/soc to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

Some clean up with helper fucntion

2024-09-04T19:09:26+00:00

Merge series from Zhang Zekun : There are some helper functions which can be used to simplify the code. So, let's use these functions to make code more simple.

ASoC: audio-graph-card2: Use helper function of_get_child_count()

2024-09-04T17:31:15+00:00

of_get_child_count() can help to get the num of child directly and we don't need to manually count the child num. No functional change with this conversion.
