ALSA: hdac: Explicitly add io.h

2015-10-13T09:33:45+00:00

Compiling the hdac extended core on arm fails with below error: sound/hda/ext/hdac_ext_bus.c: In function 'hdac_ext_writel': >> sound/hda/ext/hdac_ext_bus.c:29:2: error: implicit declaration of >> function +'writel' [-Werror=implicit-function-declaration] writel(value, addr); ^ sound/hda/ext/hdac_ext_bus.c: In function 'hdac_ext_readl': >> sound/hda/ext/hdac_ext_bus.c:34:2: error: implicit declaration of >> function +'readl' [-Werror=implicit-function-declaration] return readl(addr); This is fixed by explicitly including io.h Fixes: 99463b3a3994 - ('ALSA: hda: provide default bus io ops extended hdac') Reported-by: kbuild test robot Suggested-by: Mark Brown Signed-off-by: Vinod Koul Signed-off-by: Takashi Iwai

ALSA: hda - allow codecs to access the i915 pin/ELD callback

2015-09-02T10:23:55+00:00

This lets the interested codec be notified when an i915 pin/ELD event happens. [tiwai: Fixed a trivial build error for CONFIG_SND_HDA_I915=n] Signed-off-by: David Henningsson Signed-off-by: Takashi Iwai

ALSA: hda - Fix widget sysfs tree corruption after refresh

2015-08-26T05:43:47+00:00

When snd_hdac_refresh_widget_sysfs() is called before the first hda_widget_sysfs_init(), the next call overrides and eventually fails. This results in unexpected Oops, something like: BUG: unable to handle kernel NULL pointer dereference at 00000000000000c8 IP: [] hdmi_chmap_ctl_info+0x23/0x40 The fix is to add a check of the existing sysfs tree. Also, for more safety, this patch adds the checks of device_is_registered() in snd-hdac_refresh_wdiget_sysfs(), too.

ALSA: hdac: Add snd_hdac_get_hdac_stream()

2015-08-23T07:43:27+00:00

Add a helper to find the stream using stream tag and direction. This is useful for drivers to query stream based on stream tag and direction, fox example while downloading FW thru DSP loader code Signed-off-by: Jeeja KP Signed-off-by: Vinod Koul Signed-off-by: Takashi Iwai

ALSA: hdac: fix the spbmaxfifo API

2015-08-23T07:43:26+00:00

spbmaxfifo API is actually a query function not a set function so name it snd_hdac_ext_stream_get_spbmaxfifo() Reported-by: Pierre-Louis Bossart Signed-off-by: Vinod Koul Signed-off-by: Takashi Iwai

ALSA: hdac: Fix size allocation for ext device allocation

2015-08-23T07:43:25+00:00

While creating hdac_ext_device, we used hdev for sizeof insteadof edev, which resulted in eventual crash of the system Fix the size here Fixes: a512f5611646 ('ALSA: hdac: add hdac extended device') Reported-by: Subhransu S. Prusty Signed-off-by: Vinod Koul Signed-off-by: Takashi Iwai

ALSA: hdac: Remove the usage of key for host stream

2015-08-21T17:28:21+00:00

hdac_ext_stream assign doesn't require key mapping as in case of hdac_stream. So for host stream, the key to device mapping needs to be removed. Signed-off-by: Jeeja KP Signed-off-by: Vinod Koul Signed-off-by: Takashi Iwai

ALSA: hdac: Add support to enable SPIB for hdac ext stream

2015-08-21T17:28:20+00:00

The drivers need to set the spib and maxfifios values, so add these new APIs snd_hdac_ext_stream_set_spib() and snd_hdac_ext_stream_set_spbmaxfifo() APIs For these APIs we also need to have spib and fifos pointer, so add these to hdac_ext_stream and initialize them at stream init Signed-off-by: Jeeja KP Signed-off-by: Vinod Koul Signed-off-by: Takashi Iwai

ALSA: hdac: Add snd_hdac_ext_bus_link_power_down_all()

2015-08-21T17:28:18+00:00

New HDA controllers like Skylake sport multiple HDA links, so we need a helper to turn off all the links in one go while suspending the device so add snd_hdac_ext_bus_link_power_down_all() API Signed-off-by: Jeeja KP Signed-off-by: Vinod Koul Signed-off-by: Takashi Iwai

ALSA: hdac: Fix to read the correct offset of spcap/link register

2015-08-21T17:28:16+00:00

SPCAP and Mutilink register offset were incorrect as offset needs to be based on capability offset. So correct the offset for read/write of spcap/link register. Signed-off-by: Jeeja KP Signed-off-by: Vinod Koul Signed-off-by: Takashi Iwai
