ASoC: ti: fix davinci_mcasp_probe dependencies

2019-05-31T13:45:23Z

[ Upstream commit 7d7b25d05ef1c5a1a9320190e1eeb55534847558 ] The SND_SOC_DAVINCI_MCASP driver can use either edma or sdma as a back-end, and it takes the presence of the respective dma engine drivers in the configuration as an indication to which ones should be built. However, this is flawed in multiple ways: - With CONFIG_TI_EDMA=m and CONFIG_SND_SOC_DAVINCI_MCASP=y, is enabled as =m, and we get a link error: sound/soc/ti/davinci-mcasp.o: In function `davinci_mcasp_probe': davinci-mcasp.c:(.text+0x930): undefined reference to `edma_pcm_platform_register' - When CONFIG_SND_SOC_DAVINCI_MCASP=m has already been selected by another driver, the same link error appears even if CONFIG_TI_EDMA is disabled There are possibly other issues here, but it seems that the only reasonable solution is to always build both SND_SOC_TI_EDMA_PCM and SND_SOC_TI_SDMA_PCM as a dependency here. Both are fairly small and do not have any other compile-time dependencies, so the cost is very small, and makes the configuration stage much more consistent.

ASoC: davinci-mcasp: Fix clang warning without CONFIG_PM

2019-05-31T13:45:23Z

[ Upstream commit 8ca5104715cfd14254ea5aecc390ae583b707607 ] Building with clang shows a variable that is only used by the suspend/resume functions but defined outside of their #ifdef block: sound/soc/ti/davinci-mcasp.c:48:12: error: variable 'context_regs' is not needed and will not be emitted We commonly fix these by marking the PM functions as __maybe_unused, but here that would grow the davinci_mcasp structure, so instead add another #ifdef here.

ASoC: ti: davinci-mcasp: Move context save/restore to runtime_pm callbacks

2019-01-04T15:18:42Z

McASP can loose it's context when runtime_pm is disabled. Save and restore the context when suspending and resuming the device. Signed-off-by: Peter Ujfalusi Signed-off-by: Mark Brown

ASoC: ti: Merge davinci and omap directories

2018-12-18T12:22:43Z

Create new directory to contain all Texas Instruments specific DAI, platform and machine drivers instead of scattering them under davinci and omap directories. There is already inter dependency between the two directories becasue of McASP (on dra7x it is serviced by sDMA, not EDMA). With the upcoming AM654 we will need to introduce new platform driver for UDMA and it does not fit under davinci, nor under omap. With the move I have restructured the Kconfig to be more usable in the era of simple-sound-card: CPU DAIs can be selected individually and they will select the platform driver they can be served with. To avoid breakage, I have moved over deprecated Kconfig options so defconfig builds will work without regression.
