Revision 2, auto mute implementing HiassofT suggestion to mute/unmute using set_bias_level, rather than startup/shutdown.... "By default DAPM waits 5 seconds (pmdown_time) before shutting down playback streams so a close/stop immediately followed by open/start doesn't trigger an amp mute+unmute." Tested on both AMP+ (via DAC+) and DigiAMP+, with both options... dtoverlay=iqaudio-dacplus,unmute_amp "one-shot" unmute when kernel module loads. dtoverlay=iqaudio-dacplus,auto_mute_amp Unmute amp when ALSA device opened by a client. Mute, with 5 second delay when ALSA device closed. (Re-opening the device within the 5 second close window, will cancel mute.) Revision 4, using gpiod. Revision 5, clean-up formatting before adding mute code. - Convert tab plus 4 space formatting to 2x tab - Remove '// NOT USED' commented code Revision 6, don't attempt to "one-shot" unmute amp, unless card is successfully registered.

This patch adds headphone and microphone capability to the Audio Injector sound card. The patch also sets the bit clock ratio for use in the bcm2835-i2s driver. The bcm2835-i2s can't handle an 8 kHz sample rate when the bit clock is at 12 MHz because its register is only 10 bits wide which can't represent the ch2 offset of 1508. For that reason, the rate constraint is added. | 26 June 2016, 12:25:42 UTC |

| 6db2b8e | Matthias Reichl | 08 June 2016, 11:09:56 UTC | dmaengine: bcm2835: Avoid splitting periods into very small chunks The current cyclic DMA period splitting implementation can generate very small chunks at the end of each period. For example a 65536 byte period will be split into a 65532 byte chunk and a 4 byte chunk on the "lite" DMA channels. This increases pressure on the RAM controller as the DMA controller needs to fetch two control blocks from RAM in quick succession and could potentially cause latency issues if the RAM is tied up by other devices. We can easily avoid these situations by distributing the remaining length evenly between the last-but-one and the last chunk, making sure that split chunks will be at least half the maximum length the DMA controller can handle. This patch checks if the last chunk would be less than half of the maximum DMA length and if yes distributes the max len+4...max_len*1.5 bytes evenly between the last 2 chunks. This results in chunk sizes between max_len/2 and max_len*0.75 bytes.

Therefore total_len was stuck at 0 and the code didn't work at all. This resulted in a wrong control block layout and audio issues because the cyclic DMA callback wasn't executing on period boundaries. Fix this by adding the missing total_len update.

The currently implemented device tree is unfortunately implemented with the wrong assumption, that each dma-channel has its own dma channel, but dma-irq 11 is handling dma-channel 11-14 and dma-irq 12 is actually a "catch all" interrupt. So here we use the byname variant and require that interrupts are explicitly named via the interrupts-name property in the device tree. The use of shared interrupts is also implemented. As a side-effect this means we can now use dma channels 12, 13 and 14 in a correct manner - also testing shows that onl using channels 11 to 14 for spi and i2s works perfectly (when playing some video) Signed-off-by: Martin Sperl <kernel@martin.sperl.org> Acked-by: Eric Anholt <eric@anholt.net> Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> | 26 June 2016, 12:25:32 UTC |

| 303e0d5 | Martin Sperl | 16 March 2016, 19:25:00 UTC | dmaengine: bcm2835: limit max length based on channel type The bcm2835 dma system has 2 basic types of dma-channels: * "normal" channels * "light" channels Lite channels are limited in several aspects: * internal data-structure is 128 bit (not 256) * does not support BCM2835_DMA_TDMODE (2D) * DMA length register is limited to 16 bit. so 0-65535 (not 0-65536 as mentioned in the official datasheet) * BCM2835_DMA_S/D_IGNORE are not supported The detection of the type of mode is implemented by looking at the LITE bit in the DEBUG register for each channel. This allows automatic detection. Based on this the maximum block size is set to (64K - 4) or to 1G and this limit is honored during generation of control block chains. The effect is that when a LITE channel is used more control blocks are used to do the same transfer (compared to a normal channel). As there are several sources/target DREQS that are 32 bit wide we need to have the transfer to be a multiple of 4 as this would break the transfer otherwise. This is why the limit of (64K - 4) was chosen over the alternative of (64K - 4K).

These - as far as research and discussions show - are a artefacts remaining from the downstream legacy dma-api. Right now down-stream still includes a legacy api used only in a single (downstream only) driver (bcm2708_fb) that requires 2D DMA for speedup (DMA-channel 0). Formerly the sd-card support driver also was using this legacy api (DMA-channel 2), but since has been moved over to use dmaengine directly. The DMA-channel 3 is already masked out in the devicetree in the default property "brcm,dma-channel-mask = <0x7f35>;" So we can remove the whole masking of DMA channels.

But if we're looking for a new parent, we don't want to switch it to PLLC because the firmware will force PLLC (and thus the AXI bus clock) to different frequencies during over-temp/under-voltage, without notification to Linux. On my system, this moves the Linux-enabled HDMI state machine and DSI1 escape clock over to plld_per from pllc_per. EMMC still ends up on pllc_per, because the firmware had set it up to use that.

| aaafd58 | Eric Anholt | 18 March 2016, 19:34:59 UTC | drm: Add an encoder and connector type enum for DPI. Right now exynos is exposing DPI as a TMDS encoder and VGA connector, which seems rather misleading. This isn't just an internal detail, since xrandr actually exposes "VGA" as the output name. Define some new enums so that vc4's DPI can have a more informative name. I considered other names for the connector as well. For VC4, the Adafruit DPI kippah takes the 28 GPIO pins and routes them to a standard-ish 40-pin FPC connector, but "40-pin FPC" doesn't uniquely identify an ordering of pins (apparently some other orderings exist), doesn't explain things as well for the user (who, if anything, knows their product is a DPI kippah/panel combo), and actually doesn't have to exist (one could connect the 28 GPIOs directly to something else). Simply "DPI" seems like a good compromise name to distinguish from the HDMI, DSI, and TV connectors .

When a buffer is being dequeued using VIDIOC_DQBUF IOCTL, the exact buffer which will be dequeued is not known until the buffer has been removed from the queue. The number of planes is specific to a buffer, not to the queue. This does lead to the situation where multi-plane buffers may be requested and queued with n planes, but VIDIOC_DQBUF IOCTL may be passed an argument struct with fewer planes. __fill_v4l2_buffer() however uses the number of planes from the dequeued videobuf2 buffer, overwriting kernel memory (the m.planes array allocated in video_usercopy() in v4l2-ioctl.c) if the user provided fewer planes than the dequeued buffer had.
