2024-12-09ASoC: fsl_utils: Add function to constrain ratesChancel Liu
Platforms like i.MX93/91 only have one audio PLL. Some sample rates are not supported. Add common function to constrain rates according to different clock sources.

2019-06-06ASoC: fsl: mpc8610_hpcd/p1022_ds/p1022_rdk: use modern dai_link styleKuninori Morimoto
ASoC is now supporting modern style dai_link (= snd_soc_dai_link_component) for CPU/Codec/Platform. This patch switches to use it. mpc8610_hpcd/p1022_ds/p1022_rdk are sharing fsl_asoc_get_dma_channel() which setups platform. We need to update these by 1 patch.

2019-04-02ASoC: fsl_utils: fix a leaked reference by adding missing of_node_putWen Yang
The call to of_parse_phandle returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. Detected by coccinelle with the following warnings: ./sound/soc/fsl/fsl_utils.c:74:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 38, but without a corresponding object release within this function.

2015-01-14ASoC: fsl: Remove fsl_asoc_xlate_tdm_slot_mask()Lars-Peter Clausen
Now that the fsl DAI drivers uses the same semantics as the rest of a ASoC the custom fsl_asoc_xlate_tdm_slot_mask() callback can be removed as it is identical to the generic one. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-01-14ASoC: fsl: Update set_tdm_slot() semanticsLars-Peter Clausen
The fsl-ssi and imx-ssi drivers use inverted semantics for the tx_mask and rx_mask parameter of the set_tdm_slot() callback compared to rest of ASoC. This patch updates the driver's semantics to be consistent with the rest of ASoC, i.e. a set bit means a active slot and a cleared bit means a inactive slot. This will allow us to use the set_tdm_slot() API in a more generic way.

2014-03-25ASoC: fsl-utils: Add fsl_asoc_xlate_tdm_slot_mask() support.Xiubo Li
This patch add fsl_asoc_xlate_tdm_slot_mask() support for utils. For the some spcified DAI driver, this will be used to generate the TDM slot TX/RX mask. And the TX/RX mask will use a 0 bit for an active slot as default, and the default active bits are at the LSB of the masks.

There is some amount of code duplication between mpc8610_hpcd and p1022_ds machine drivers, and the same code will be duplicated again when another new machine driver is added. The patch creates fsl_utils to accommodate the common functions to stop the code duplication.
