* ASoC: omap-mcbsp: Add PM QoS support for McBSP to prevent glitchesMatt Ranostay2017-02-011-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | We can get audio errors if hitting deeper idle states on omaps: [alsa.c:230] error: Fatal problem with alsa output, error -5. [audio.c:614] error: Error in writing audio (Input/output error?)! This seems to happen with off mode idle enabled as power for the whole SoC may get cut off between filling the McBSP fifo using DMA. While active DMA blocks deeper idle states in hardware, McBSP activity does not seem to do so. Basing the QoS latency calculation on the FIFO size, threshold, sample rate, and channels.

* ASoC: omap-mcbsp: sidetone: Use the new callback for iclk handlingPeter Ujfalusi2016-06-101-0/+1
| | | | | | | | | | | | | | | | The McBSP sidetone (in OMAP3 McBSP2 and 3 module) is working with the module's interface clock. When the sidetone is enabled the iclk must not idle because it will result in choppy sidetone. Switch to use the new callback for handling the iclk allow/deny idle configuration. For this the driver needs to get the module's ick clock and pass the clk pointer to the callback. In DT boot, the pdata-quirk is going to set up the callback for the driver so save it if it is set in the pdata of the device.

* ASoC: omap: Use common DAI DMA dataLars-Peter Clausen2013-04-031-3/+4
| | | | | | | | | | | | | Use the common DAI DMA data struct for omap, this allows us to use the common helper function to configure the DMA slave config based on the DAI DMA data. For omap-dmic and omap-mcpdm also move the DMA data from a global variable to the driver state struct.

* ARM/ASoC: omap-mcbsp: Remove CLKR/FSR mux configuration codePeter Ujfalusi2012-08-221-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the feature to configure the CLKR/FSR mux on McBSP port with 6pin configuration. When moving to devicetree these callback can no longer be used in a clean way anymore. If a board require to change the 6pin port to work in 4pin setup it needs to set up the mux in the board file. For OMAP2/3: u32 devconf0; /* McBSP1 CLKR/FSR signal to be connected to CLKX/FSX pin */ devconf0 = omap_ctrl_readl(OMAP2_CONTROL_DEVCONF0); devconf0 |= OMAP2_MCBSP1_CLKR_MASK | OMAP2_MCBSP1_FSR_MASK; omap_ctrl_writel(devconf0, OMAP2_CONTROL_DEVCONF0); For OMAP4: u32 mcbsp_pad; /* McBSP4 CLKR/FSR signal to be connected to CLKX/FSX pin */ mcbsp_pad = omap4_ctrl_pad_readl(OMAP2_CONTROL_DEVCONF0); mcbsp_pad |= ((1 << 31) | (1 << 30)); omap4_ctrl_pad_writel(mcbsp_pad, OMAP2_CONTROL_DEVCONF0); In case when the kernel is booted with DT blob the pinctrl-single will be provided as soon as it is enabled on the platform.

* ASoC: omap-mcbsp: Create a single driver for McBSPPeter Ujfalusi2012-03-121-23/+81
| | | | | | | | | | | | | | | | | | | | | | | The OMAP McBSP driver stack used to contain two different drivers. One of them was used as kind low-level access to the IP, while the other driver was the ASoC DAI driver. There were global, shared structures, in different places, the McBSP instances are reffered with id numbers (sometimes 0 based, in other cases 1 based id numbers). Create one single driver for OMAP McBSP with name: omap-mcbsp. Convert the old omap-mcbsp driver initially to be a library for the omap-mcbsp DAI driver. With this change we can get rid of all global variables, structures. Further cleanup is coming...
