[alsa-devel] [PATCH 0/7] ALSA: firewire: apply deleyed registration to all drivers
by Takashi Sakamoto 25 Apr '16

25 Apr '16

Hi, Commit b59fb1900b4fee('ALSA: dice: postpone card registration') applied delayed registration[1] of sound card instance to ALSA dice driver. This idea is also nice for drivers in ALSA firewire stack because in IEEE 1394 bus adding units is corresponding to bus reset and the actual units tend not to work well during bus-reset state. This patchset adds a new function to firewire-lib module to schedule a delayed work for sound card registration. Currently, the work is commonly scheduled 2 seconds after time of the last bus-reset recorded by Linux firewire core. Then, take all drivers to use it as Dice driver does. Related to this patchset, I'd like to cancel a discussion about my proposed patchset to remove unpractical module parameters from ALSA bebob/fireworks[2]. I'm sorry for reviewers but my work priority to this patchset is prior to the former one.

[alsa-devel] [PATCH 0/4] ASoC: simple-card/davinci-mcasp: System clock configuration support
by Peter Ujfalusi 22 Apr '16

22 Apr '16

Hi, Currently davinci-mcasp is hardwired for two configuration regarding to reference clock: McASP is master: AHCLKX is selected as source of the reference clock used to generate the FS and BCLK McASP is slave: AHCLKX is selected as output and the default AUXCLK is routed there. This works in most of the boards, but not all configuration can be supported with this limitation. McASP uses it's internal AUXCLK as a reference clock. AUXCLK can be sourced from the external AHCLKX pin or from internal functional clock. If the board uses McASP as master and AHCLKX is not receiving clock, we need to be able to select the internal clock source to be able to generate the FS and BCLK. Since we try to move all of our boards to simple-card instead of the davinci-evm custom machine driver, I have included Jyri's two patch to add the needed support for it to be able to select clocks and directions. I remember the discussion regarding to clock IDs, and to try to move to common clock framework. I have taken a look at that path and I'm not convinced that by trying to add ASoC level common clock handling will simplify or makes things cleaner/simpler.

[ 5.661807] sst-mfld-platform sst-mfld-platform: Slot control: codec_in rx deinterleaver codec_in1_1 doesn't have DAPM widget!!! This is caused when check for control is not being associated with a dapm widget, but the check is wrong as the else case maybe triggered when widget is not powered up, so we should check if widget is associated before printing this message.
