2024-09-09ASoC: Switch back to struct platform_driver::remove()Uwe Kleine-König
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.

2023-03-20ASoC: fsl: fsl_asrc: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2017-02-27scripts/spelling.txt: add "followings" pattern and fix typo instancesMasahiro Yamada
Fix typos and add the following to the scripts/spelling.txt: followings||following While we are here, add a missing colon in the boilerplate in DT binding documents. The "you SoC" in allwinner,sunxi-pinctrl.txt was fixed as well. I reworded "as the followings:" to "as follows:" for drivers/usb/gadget/udc/renesas_usb3.c.

2016-09-20ASoC: fsl_asrc: use flat regmap cacheMarek Vasut
Same as commit ce492b3b8f99cf9d2f807ec22d8805c996a09503 Subject: drm/fsl-dcu: use flat regmap cache Using flat regmap cache instead of RB-tree to avoid the following lockdep warning on driver load: WARNING: CPU: 0 PID: 1 at kernel/locking/lockdep.c:2871 lockdep_trace_alloc+0x104/0x128 DEBUG_LOCKS_WARN_ON(irqs_disabled_flags(flags)) The RB-tree regmap cache needs to allocate new space on first writes. However, allocations in an atomic context (e.g. when a spinlock is held) are not allowed. The function regmap_write calls map->lock, which acquires a spinlock in the fast_io case. Since the driver uses MMIO, the regmap bus of type regmap_mmio is being used which has fast_io set to true.

Add 8kHz, 11.025kHz, 16kHz, 22.05kHz output sample rate support. According referance menual, "Limited support for the case when output sampling rates is between 8kHz and 30kHz. The limitation is the supported ratio (Fsin/Fsout) range as between 1/24 to 8."
