8a1115ff6b scripts/spelling.txt: add "disble(d)" pattern and fix typo instances
Fix typos and add the following to the scripts/spelling.txt:

  disble||disable
  disbled||disabled

I kept the TSL2563_INT_DISBLED in /drivers/iio/light/tsl2563.c
untouched.  The macro is not referenced at all, but this commit is
touching only comment blocks just in case.

30cd849771 ASoC: AMD: remove unused ‘dma_buffer’
In acp_dma_hw_params(), 'dma_buffer' is initialized, but not used. So
remove it.

sound/soc/amd/acp-pcm-dma.c: In function ‘acp_dma_hw_params’:
sound/soc/amd/acp-pcm-dma.c:673:25: warning: variable ‘dma_buffer’ set but not used [-Wunused-but-set-variable]
  struct snd_dma_buffer *dma_buffer;

115c725488 ASoC: constify snd_pcm_ops structures
Check for snd_pcm_ops structures that are only stored in the ops field of a
snd_soc_platform_driver structure or passed as the third argument to
snd_pcm_set_ops.  The corresponding field or parameter is declared const,
so snd_pcm_ops structures that have this property can be declared as const
also.

The semantic patch that makes this change is as follows:

7cb1dc8109 ASoC: AMD: Add missing include file
arm:allmodconfig, s390:allmodconfig, sparc64:allmodconfig, and probably
other builds fail with

sound/soc/amd/acp-pcm-dma.c:83:2: error:
	implicit declaration of function ‘readl’
sound/soc/amd/acp-pcm-dma.c:88:2: error:
	implicit declaration of function ‘writel’

Include linux/io.h explicitly to fix the problem.

c36d9b3f6d ASoC: AMD: Manage ACP 2.x SRAM banks power
ACP SRAM banks gets turned on when ACP is powered on.
Not all banks are used for playback/capture. So, power on
required banks during audio device open and power off during
audio device close.

1927da9355 ASoC: AMD: add pm ops
genpd will power off/on ACP to manage runtime ACP PM. ACP runtime PM
hooks are added to get it deinitialized and initialized respectively,
after it is powered off/on.

When system goes to suspend when audio usecase is active, ACP will
be powered off through genpd. When it resumes, ACP needs to be
initialized and reconfigured.

7c31335a03 ASoC: AMD: add AMD ASoC ACP 2.x DMA driver
ACP IP has internal DMA controller with multiple channels which
can be programmed in cyclic/non cyclic manner. ACP can generate
interrupt upon completion of DMA transfer, if required.
The PCM driver provides the platform DMA component to ALSA core.
