2017-12-06ASoC: Intel: Skylake: Remove second shim read in register_pollSubhransu S. Prusty1-3/+1
No need to read the register again if the value read has already matched the target during the loop. So remove the second shim read. Signed-off-by: Subhransu S.

2017-01-06ASoC: Intel: Common: Update dsp register poll implementationJeeja KP1-26/+26
Poll implementation is not quite accurate, especially for smaller values of timeout or timeout values close to the actual timeout needed Use jiffies to set the timeout value and time_before() to get the accurate time. So update the dsp register poll implementation to provide accurate timeout using jiffies.

2016-07-11ASoC: intel: Fix sst-dsp dependency on dw stuffTakashi Iwai1-67/+0
The recent commit [a92ea59b74e2: ASoC: Intel: sst: only select sst-firmware when DW DMAC is built-in] introduced more strict kconfig dependency (depends on DW_DMAC_CORE=y) for avoiding the build failures due to dependency messes in intel-sst. This makes, however, it impossible to use this driver with the modularized systems, i.e. typically on Linux distros. The problem addressed in the commit above is that sst_dsp_new() and sst_dsp_free() includes the firmware init / finish that call dw_*() functions. Thus building it as built-in with DW_DMAC_CORE module results in the missing symbols. However, these sst_dsp functions are basically called only from the drivers that depend on DW_DMAC_CORE already. That is, once when these functions are split out, the rest can be independent from dw stuff. This patch attempts to solve the issue by the following: - Split sst-dsp stuff into two modules: snd-soc-sst-dsp and snd-soc-sst-firmware. - Move sst_dsp_new() and sst_dsp_free() to the latter module so that the former module can be independent from DW_DMAC_CORE. - Add a new kconfig SND_SOC_INTEL_SST_FIRMWARE to select the latter module by machine drivers. One only remaining pitfall is that each machine driver has to select SND_SOC_INTEL_SST_FIRMWARE carefully depending on DW_DMAC_CORE. This can't be done cleanly due to the restriction of the current kbuild.

2015-11-25ASoC: Intel: sst: only select sst-firmware when DW DMAC is built-inJie Yang1-1/+1
The previous commit ef3e199a49c8 ("ASoC: Intel: sst: only use sst-firmware when DW DMAC is available") does not fix the 0day building errors thoroughly: sound/built-in.o: In function 'dw_dma_remove' sound/built-in.o: In function 'dw_dma_probe' Here we fallback to select sst-firmware only when DW DMAC is built-in selected. We may need to refactor sst common driver and split DW related codes to platform driver, but ATM, this fallback may be the smallest fix. Please be noticed that after applying this patch, we may need select DW DMAC manually in DMA driver menu, before we can prompt and select HSW/BDW and old BYT machines.

Currentlly, we use Synopsys DesignWare DMA Controller for baytrail/haswell/broadwell ADSP firmware loading, but for skylake, we don't use it, compiling sst-firmware.c may introduce error when CONFIG_DW_DMAC_CORE is not enabled: sound/built-in.o: In function `sst_dma_new': (.text+0xd7b38): undefined reference to `dw_dma_probe' sound/built-in.o: In function `sst_dma_free': (.text+0xd7c0a): undefined reference to `dw_dma_remove' Here we only compile sst-firmware when CONFIG_DW_DMAC_CORE is selected, to fix the linking error issue.
