2025-06-08ASoC: renesas: Use helper function for_each_child_of_node_scoped()Ai Chao
The for_each_child_of_node_scoped() helper provides a scope-based clean-up functionality to put the device_node automatically, and as such, there is no need to call of_node_put() directly.

2025-02-05ASoC: rsnd: adjust convert rate limitationKuninori Morimoto
Current rsnd driver supports Synchronous SRC Mode, but HW allow to update rate only within 1% from current rate. Adjust to it. Becially, this feature is used to fine-tune subtle difference that occur during sampling rate conversion in SRC. So, it should be called within 1% margin of rate difference. If there was difference over 1%, it will apply with 1% increments by using loop without indicating error message.

2025-02-05ASoC: rsnd: don't indicate warning on rsnd_kctrl_accept_runtime()Kuninori Morimoto
rsnd_kctrl_accept_runtime() (1) is used for runtime convert rate (= Synchronous SRC Mode). Now, rsnd driver has 2 kctrls for it (A): "SRC Out Rate Switch" (B): "SRC Out Rate" // it calls (1) (A): can be called anytime (B): can be called only runtime, and will indicate warning if it was used at non-runtime. To use runtime convert rate (= Synchronous SRC Mode), user might uses command in below order. (X): > amixer set "SRC Out Rate" on > aplay xxx.wav & (Y): > amixer set "SRC Out Rate" 48010 // convert rate to 48010Hz (Y): calls B (X): calls both A and B. In this case, when user calls (X), it calls both (A) and (B), but it is not yet start running. So, (B) will indicate warning. This warning was added by commit b5c088689847 ("ASoC: rsnd: add warning message to rsnd_kctrl_accept_runtime()"), but the message sounds like the operation was not correct. Let's update warning message. The message is very SRC specific, implement it in src.c Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Reviewed-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Link: https://patch.msgid.link/8734gt2qed.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>

Rename the "sh" folder to "renesas" to better reflect the Renesas-specific drivers.
