      ASoC: Change the PCM runtime array to a list · 1a497983
      由 Mengdong Lin 提交于 
      Currently the number of DAI links is statically defined by the machine
driver at build time using an array. This makes it difficult to shrink/
grow the number of DAI links at runtime in order to reflect any changes
in topology.

We can change the DAI link array in the core to a list so that PCMs and
FE DAI links can be added and deleted at runtime to reflect changes in
use case and DSP topology. The machine driver can still register DAI links
as an array.

As the 1st step, this patch change the PCM runtime array to a list. A new
PCM runtime is added to the list when a DAI link is bound successfully.

Later patches will further implement the DAI link list.

More:
- define snd_soc_new/free_pcm_runtime() to create/free a runtime.
- define soc_add_pcm_runtime() to add a runtime to the rtd list.
- define soc_remove_pcm_runtimes() to clean up the runtime list.

- traverse the rtd list to probe the link components and dais.

- Add a field "num" to PCM runtime struct, used to specify the device
  number when creating the pcm device, and for a soc card to access
  its dai_props array.

- The following 3rd party machine/platform drivers iterate the rtd list
  to check the runtimes:

      ASoC: simple-card: Enable and disable DAI clocks as needed · f9911803
      由 Jyri Sarha 提交于 
      Call clk_prepare_enable() and clk_disable_unprepare() for cpu dai
clock and codec dai clock in dai statup and shutdown callbacks. This
to make sure the related clock are enabled when the audio device is
used.

      ASoC: simple-card: Fix crash in asoc_simple_card_unref() · 7ddfdb5c
      由 Geert Uytterhoeven 提交于 
      If asoc_simple_card_probe() fails, asoc_simple_card_unref() may be
called before dev_set_drvdata(), causing a NULL pointer dereference in
asoc_simple_card_unref():

    Unable to handle kernel NULL pointer dereference at virtual address 000000d4
    ...
    PC is at asoc_simple_card_unref+0x14/0x48
    LR is at asoc_simple_card_probe+0x3d4/0x40c

This typically happens because asoc_simple_card_parse_of() returns
-EPROBE_DEFER, but other failure modes are possible.
devm_snd_soc_register_card()/snd_soc_register_card() may fail either
before or after dev_set_drvdata().

Pass a snd_soc_card pointer instead of a platform_device pointer to
asoc_simple_card_unref() to fix this.

Note that if CONFIG_OF_DYNAMIC=n, of_node_put() is a dummy, and gcc may
optimize away the loop over card->dai_link, never actually dereferencing
card, and thus avoiding the crash...

      ASoC: simple-card: Initialize headphone and mic GPIO numbers · 2dbab978
      由 Geert Uytterhoeven 提交于 
      The uninitialized default of 0 for gpio_hp_det and gpio_mic_det doesn't
play well with asm-generic's gpio_is_valid():

	static inline bool gpio_is_valid(int number)
	{
		return number >= 0 && number < ARCH_NR_GPIOS;
	}

Hence on r8a7740/armadillo-legacy:

	sh-mobile-hdmi sh-mobile-hdmi: SH Mobile HDMI Audio Codec
	sh-mobile-hdmi sh-mobile-hdmi: ASoC: DAPM unknown pin Headphones
	sh-mobile-hdmi sh-mobile-hdmi: ASoC: DAPM unknown pin Mic Jack

After that the kernel log is spammed ca. 7 times per second with:

	sh-mobile-hdmi sh-mobile-hdmi: ASoC: DAPM unknown pin Headphones

Initialize the GPIO numbers with a negative number (-ENOENT) to fix this.

Since the asoc_simple_card_sub_parse_of() is used in simple-card module only,
and the third argument is just used to get the node ponters address, so there is
no need it must to be 'const' type.
