Merge series "use semicolons rather than commas to separate statements" from Julia Lawall <Julia.Lawall@inria.fr>: These patches replace commas by semicolons. This was done using the Coccinelle semantic patch (http://coccinelle.lip6.fr/) shown below. This semantic patch ensures that commas inside for loop headers will not be transformed. It also doesn't touch macro definitions. Coccinelle ensures that braces are added as needed when a single-statement branch turns into a multi-statement one. This semantic patch has a few false positives, for variable delcarations such as: LIST_HEAD(x), *y; The semantic patch could be improved to avoid these, but for the moment they have been removed manually (2 occurrences). // <smpl> @initialize:ocaml@ @@ let infunction p = (* avoid macros *) (List.hd p).current_element <> "something_else" let combined p1 p2 = (List.hd p1).line_end = (List.hd p2).line || (((List.hd p1).line_end < (List.hd p2).line) && ((List.hd p1).col < (List.hd p2).col)) @bad@ statement S; declaration d; position p; @@ S@p d // special cases where newlines are needed (hope for no more than 5) @@ expression e1,e2; statement S; position p != bad.p; position p1; position p2 : script:ocaml(p1) { infunction p1 && combined p1 p2 }; @@ - e1@p1,@S@p e2@p2; + e1; e2; @@ expression e1,e2; statement S; position p != bad.p; position p1; position p2 : script:ocaml(p1) { infunction p1 && combined p1 p2 }; @@ - e1@p1,@S@p e2@p2; + e1; e2; @@ expression e1,e2; statement S; position p != bad.p; position p1; position p2 : script:ocaml(p1) { infunction p1 && combined p1 p2 }; @@ - e1@p1,@S@p e2@p2; + e1; e2; @@ expression e1,e2; statement S; position p != bad.p; position p1; position p2 : script:ocaml(p1) { infunction p1 && combined p1 p2 }; @@ - e1@p1,@S@p e2@p2; + e1; e2; @@ expression e1,e2; statement S; position p != bad.p; position p1; position p2 : script:ocaml(p1) { infunction p1 && combined p1 p2 }; @@ - e1@p1,@S@p e2@p2; + e1; e2; @r@ expression e1,e2; statement S; position p != bad.p; @@ e1 ,@S@p e2; @@ expression e1,e2; position p1; position p2 : script:ocaml(p1) { infunction p1 && not(combined p1 p2) }; statement S; position r.p; @@ e1@p1 -,@S@p +; e2@p2 ... when any // </smpl> --- sound/firewire/fireworks/fireworks_pcm.c | 2 +- sound/pci/hda/patch_ca0132.c | 2 +- sound/pci/hda/patch_hdmi.c | 2 +- sound/soc/codecs/madera.c | 4 ++-- sound/soc/codecs/wm8350.c | 3 ++- sound/soc/intel/boards/bytcr_rt5651.c | 2 +- sound/soc/samsung/snow.c | 2 +- sound/soc/soc-dapm.c | 2 +- sound/soc/sof/intel/hda-dsp.c | 2 +- 9 files changed, 11 insertions(+), 10 deletions(-)

Merge series "ASoC: sun8i-codec: support for AIF2 and AIF3" from Samuel Holland <samuel@sholland.org>: This series adds support the other two AIFs present in the sun8i codec, which can be used for codec2codec DAI links. This series first fills out the DAI driver, removing assumptions that were made for AIF1 (16 bits, 2 channels, certain clock inversions). Some new logic is required to handle 3 DAIs and the ADC/DAC sharing the same clock. Finally, it adds the new DAIs, and hooks them up with DAPM widgets and routes per the hardware topology. To minimize the number of patches in this series, related device tree patches (increasing #sound-dai-cells, adding new DAI links) will be sent separately. Changes from v1: - Patches 1-8 from v1 (DAPM changes) were merged - Prefixed AIF constants with "SUN8I_CODEC_" [1, 7, 10, 16, 17] - Renamed variables in sun8i_codec_set_fmt for clarity [3] - Update sysclk->sysclk_rate if later calls to hw_params change the sample rate (thanks Chen-Yu for reminding me of this) [11] - Select COMMON_CLK for clk_set_rate_exclusive [12] - Add comments and hopefully clarify the clock protection logic [12] - Make the error message more concise and put it on one line [12] - Drop the "reg" variable holding SUN8I_AIF_CLK_CTRL(dai->id) [15] - Rename "div_reg" to "clk_reg" and adjust comments for clarity [17] - Improve the AIF2/AIF3 rate mismatch error message [17] - Minor grammar/wording fixes in commit messages [2, 4, 7, 8, 16, 17] - Added Maxime's Acked-by: [1-2, 4-9, 11, 13-14, 16] Samuel Holland (17): ASoC: sun8i-codec: Prepare to extend the DAI driver ASoC: sun8i-codec: Program DAI format before clock inversion ASoC: sun8i-codec: Enable all supported clock inversions ASoC: sun8i-codec: Use the provided word size ASoC: sun8i-codec: Round up the LRCK divisor ASoC: sun8i-codec: Correct the BCLK divisor calculation ASoC: sun8i-codec: Support the TDM slot binding ASoC: sun8i-codec: Enforce symmetric DAI parameters ASoC: sun8i-codec: Enable all supported sample rates ASoC: sun8i-codec: Automatically set the system sample rate ASoC: sun8i-codec: Constrain to compatible sample rates ASoC: sun8i-codec: Protect the clock rate while streams are open ASoC: sun8i-codec: Require an exact BCLK divisor match ASoC: sun8i-codec: Enable all supported PCM formats ASoC: sun8i-codec: Generalize AIF clock control ASoC: sun8i-codec: Add the AIF2 DAI, widgets, and routes ASoC: sun8i-codec: Add the AIF3 DAI, widgets, and routes sound/soc/sunxi/Kconfig | 1 + sound/soc/sunxi/sun8i-codec.c | 834 ++++++++++++++++++++++++++++------ 2 files changed, 699 insertions(+), 136 deletions(-) -- 2.26.2 -

On i.MX8QM, there are separate interrupts for TX and RX. As the EDMA can't be configured to swing back to first FIFO after writing the second FIFO, so we need to force the burst size to be 2 on i.MX8QM. And EDMA don't support to shift the data from S24_LE to S16_LE, so the supported TX format is also different on i.MX8QM. Signed-off-by:

The change removes the platform_data include/definition. It only contains some values for the MICBIAS. These are moved into 'dt-bindings/sound/adi,adau1977.h' so that they can be used inside device-trees. When moving then, they need to be converted to pre-compiler defines, so that the DT compiler can understand them. The driver then, also needs to include the new 'dt-bindings/sound/adi,adau1977.h' file. Signed-off-by:

All platforms that use the jz4740-i2s driver have been switched to devicetree for a while now and the assignment of the DMA peripheral ID is done in the devicetree. It is no longer necessary to manually assign the peripheral ID in the driver, so remove that. The DMA driver does not even look at the value assigned in the driver anymore and always uses the value provided by the devicetree. Signed-off-by:

AIF3 has some differences from AIF1 and AIF2: - It supports one channel only - It supports master mode only - It is not directly connected to any of the mixers; instead all audio goes through a mux with AIF2. - It does not have its own clock dividers; instead it reuses AIF2 BCLK and LRCK. This means that when both AIF2 and AIF3 are active, they must use the same sample rate and total frame width. Since AIF2 and AIF3 are only used for codec2codec DAI links, constraints are not applicable here; the only thing we can do when the rates don't match is report an error. Make the necessary adjustments to support this AIF. Signed-off-by:

The AIF clock control register has the same layout for all three AIFs. The only difference between them is that AIF3 is missing some fields. We can reuse the same register field definitions for all three registers, and use the DAI ID to select the correct register address. Signed-off-by:

Now that the DAI clock setup is correct for all hardware-supported PCM formats, we can enable them in the driver. With the appropriate support in the CPU DAI driver, this allows userspace to access the additional formats. Since this codec is connected to the CPU via a DAI, not directly, we do not care if the CPU DAI is using 3-byte or 4-byte formats, so we can support them both. Acked-by:

Now that we guarantee that SYSCLK is running at the optimal rate when hw_params succeeds, and that it will continue running at that rate, SYSCLK will always be an integer multiple of BCLK. So we can always pick the exact divider, not just the closest divider. Acked-by:

The codec's clock input is shared among all AIFs, and shared with other audio-related hardware in the SoC, including I2S and SPDIF controllers. To ensure sample rates selected by userspace or by codec2codec DAI links are maintained, the clock rate must be protected while it is in use. Signed-off-by:
-
Samuel Holland authored
While another stream is active, only allow userspace to use sample rates that are compatible with the current SYSCLK frequency. This ensures the actual sample rate will always match what is given in hw_params. Acked-by:

Samuel Holland authored
The sun8i codec has three clock/sample rate domains: - The AIF1 domain, with a sample rate equal to AIF1 LRCK - The AIF2 domain, with a sample rate equal to AIF2 LRCK - The SYSCLK domain, containing the ADC, DAC, and effects (AGC/DRC), with a sample rate given by a divisor from SYSCLK. The divisor is controlled by the AIF1_FS or AIF2_FS field in SYS_SR_CTRL, depending on if SYSCLK's source is AIF1CLK or AIF2CLK, respectively. The exact sample rate depends on if SYSCLK is running at 22.6 MHz or 24.6 MHz. When an AIF (currently only AIF1) is active, the ADC and DAC should run at that sample rate to avoid artifacting. Sample rate conversion is only available when multiple AIFs are active and are routed to each other; this means the sample rate conversion hardware usually cannot be used. Only attach the event hook to the channel 0 AIF widgets, since we only need one event when a DAI stream starts or stops. Channel 0 is always brought up with a DAI stream, regardless of the number of channels in the stream. The ADC and DAC (along with their effects blocks) can be used even if no AIFs are in use. In that case, we should select an appropriate sample rate divisor, instead of keeping the last-used AIF sample rate. 44.1/48 kHz was chosen to balance audio quality and power consumption. Since the sample rate is tied to active AIF paths, disabling pmdown_time allows switching to the optimal sample rate immediately, instead of after a 5 second delay. Signed-off-by:

The system sample rate programmed into the hardware is really a clock divider from SYSCLK to the ADC and DAC. Since we support two SYSCLK frequencies, we can use all sample rates corresponding to one of those frequencies divided by any available divisor. This commit enables support for those sample rates. It also stops advertising support for a 64 kHz sample rate, which is not supported. Acked-by:

The AIFs have a single register controlling DAI parameters in both directions, including BCLK/LRCK divisor and word size. The DAIs produce only noise or silence if any of these parameters is wrong. Therefore, we need to enforce symmetry for these parameters, so starting a new substream will not break an existing substream. Acked-by:

Now that BCLK and LRCK rate calculations in the driver can handle any hardware-supported slot width and number of slots, allow overriding those parameters from the device tree. Acked-by:
-
Samuel Holland authored
Previously, the BCLK divisor calculation assumed zero padding and exactly two slots. In order to support the TDM slot binding and 20/24-bit word sizes, those assumptions must be removed. Due to hardware limitations, the BCLK/LRCK ratio is not as simple as "slot_width * slots". However, the correct value is already calculated elsewhere in this function, since it must also be programmed into the hardware. Reuse that value to calculate the correct SYSCLK/BCLK divisor. Acked-by:
-
Samuel Holland authored
The codec supports only power-of-two BCLK/LRCK divisors. If either the slot width or the number of slots is not a power of two, the LRCK divisor must be rounded up to provide enough space. To do that, use order_base_2 (instead of ilog2, which rounds down). Since the rounded divisor is also needed for setting the SYSCLK/BCLK divisor, return the order base 2 instead of fully calculating the hardware register encoding. Acked-by:
-
Samuel Holland authored
The hardware supports 8 to 24-bit word sizes on all three of its DAIs, only one of which is connected to the CPU DAI. Program the word size based on the actual selected format, instead of assuming limitations from another driver (which, incedentally, has patches pending to remove that limitation). Acked-by:

Samuel Holland authored
When using the I2S, LEFT_J, or RIGHT_J format, the hardware supports independent BCLK and LRCK inversion control. When using DSP_A or DSP_B, LRCK inversion is not supported. The register bit is repurposed to select between DSP_A and DSP_B. Extend the driver to support this. Signed-off-by:
-
Samuel Holland authored
The LRCK inversion bit has a different meaning in DSP mode: it selects between the DSP A and DSP B formats. To support this, we need to know if the selected format is a DSP format. One easy way to do this is to set the format field before the clock inversion fields. Acked-by:

In preparation for adding additional DAIs to this component, convert the DAI driver definition to an array. Since this changes all of the lines in the definition anyway, let's move it closer to the ops function definitions, instead of on the far side of the DAPM arrays. And while moving the DAI driver ops, rename the set_fmt hook to match the usual naming scheme. Give the existing DAI an explicit ID and more meaningful stream names, so it will remain unique as more DAIs are added. The AIF widget streams must be updated to match. Acked-by:
