2018-01-10ASoC: ux500: add MODULE_LICENSE tagArnd Bergmann1-0/+4
This adds MODULE_LICENSE/AUTHOR/DESCRIPTION tags to the ux500 platform drivers, to avoid these build warnings: WARNING: modpost: missing MODULE_LICENSE() in sound/soc/ux500/snd-soc-ux500-plat-dma.o WARNING: modpost: missing MODULE_LICENSE() in sound/soc/ux500/snd-soc-ux500-mach-mop500.o The company no longer exists, so the email addresses of the authors don't work any more, but I've added them anyway for consistency.

2017-08-21ASoC: ux500: Remove unnecessary function callDonglin Peng1-1/+0
First of all,the address of pdev->dev is assigned to mop500_card.dev, then the function platform_set_drvdata copies the value the variable card to pdev->dev.driver_data,but when calling snd_soc_register_card, the function dev_set_drvdata(card->dev, card) will also do the same copy operation,so i think that the former copy operation can be removed.

2017-07-17ASoC: ux500: Restore platform DAI assignmentsJohan Hovold1-0/+4
This reverts commit f1013cdeeeb9 ("ASoC: ux500: drop platform DAI assignments"), which seems to have been based on a misunderstanding and prevents the platform driver callbacks from being made (e.g. to preallocate DMA memory). The real culprit for the warnings about attempts to create duplicate procfs entries was commit 99b04f4c4051 ("ASoC: add Component level pcm_new/pcm_free" that broke PCM creation on systems that use more than one platform component.

2017-03-06ASoC: ux500: drop platform DAI assignmentsLinus Walleij1-4/+0
This platform is completely probed by device tree nowadays, so we need to do a bigger cleanup removing all the non-DT codepaths. This cleanup must however go in as a fix since it fixes a regression. Currently when Ux500 audio is enabled, dmesg complains like this: entry->name == "prealloc" entry->name == "prealloc_max" entry->name == "prealloc" ------------[ cut here ]------------ WARNING: CPU: 0 PID: 95 at ../fs/proc/generic.c:346 proc_register+0xf0/0x110 proc_dir_entry 'sub0/prealloc' already registered (...) entry->name == "prealloc_max" ------------[ cut here ]------------ WARNING: CPU: 0 PID: 95 at ../fs/proc/generic.c:346 proc_register+0xf0/0x110 proc_dir_entry 'sub0/prealloc_max' already registered (...) snd-soc-mop500 soc:sound: ab8500-codec-dai.0 <-> 80124000.msp mapping ok entry->name == "prealloc" entry->name == "prealloc_max" entry->name == "prealloc" ------------[ cut here ]------------ WARNING: CPU: 0 PID: 95 at ../fs/proc/generic.c:346 proc_register+0xf0/0x110 proc_dir_entry 'sub0/prealloc' already registered (...) entry->name == "prealloc_max" ------------[ cut here ]------------ WARNING: CPU: 0 PID: 95 at ../fs/proc/generic.c:346 proc_register+0xf0/0x110 proc_dir_entry 'sub0/prealloc_max' already registered snd-soc-mop500 soc:sound: ab8500-codec-dai.1 <-> 80125000.msp mapping ok This is because PCMs are created twice for the same hardware, and this happens because both "platform" and "CPU" DAI links are specified. But platform/CPU is an either/or pair, not a both/and pair. This has maybe worked in the past, but it is causing trouble now, so let us begin the cleanups by removing the platform assignment and silencing the boot noise, and make a proper DT cleanup for the next kernel cycle.

We're getting closer to fully enabling the Ux500 ASoC driver for Device Tree. When we switch over from using AUXDATA we'll need to match platform by only Device Tree nodes.

2012-11-23ASoC: Ux500: Initialise PCM from MSP probe rather than as a deviceLee Jones1-2/+2
The PCM is a pseudo-device. It doesn't have any of it's own registers or hardware. It rather acts as a layer of abstraction for DMA transfers. Hence, instead of classifying it as a device in its own right, we call the initialisation from the MSP driver.
