2022-04-06ASoC: rt1016: enable buildingStephen Kitt2-0/+7
The rt1016 driver wasn't listed in Kconfig and Makefile, which AFAICT means it isn't ever built. This patch adds the appropriate entries to Kconfig and Makefile.

The correct check sequence instead is: - skip all ratios lower than one and higher than 512 - skip all odd ratios except for 1:1 - skip 1:1 ratio if and only if !support_1_1_ratio And for all others, calculate the appropriate divider.

2022-04-05ASoC: ak4613: add TDM256 supportKuninori Morimoto1-8/+237
AK4613 has STEREO/TDM512/TDM256/TDM128 mode. Renesas is the only user of ak4613 on upstream for now, and is using it as STEREO mode, because of board connection. Thus, current driver is supporting STEREO mode only, and other modes are not supported. But I noticed that I can try first 2ch out of TDM256 mode 8ch Playback even in such a situation. But because of board connection, I can't test full TDM256 mode, and/or other TDM mode. Thus I don't want to add new DT propaty for now. This patch enables TDM256 mode test by "ifdef style", but it has no effect to current supported STEREO mode. You can define AK4613_ENABLE_TDM_TEST to try TDM256 mode. Please don't hesitate to break current code if you can add full TDM256 and/or other TDM mode. You don't need to care compatibility with Renesas.

2022-04-05ASoC: soc-utils: Add helper to calculate BCLK from TDM infoRichard Fitzgerald2-0/+47
Add a helper function snd_soc_tdm_params_to_bclk() to calculate the bclk from params info and the tdm sots configuration. When using a TDM frame of N slots of width W bits: bclk = sample_rate * N * W As a convenience to simplify calling code, if the slot count or slot width are 0 a value will be obtained from the params. This allows calling code to use this one function to handle cases of TDM where only one parameter is fixed, or I2S where the slot width is fixed (for example to set a 32-bit slot for 24-bit samples). Also as a convenience the slot count can optionally be rounded up to a multiple. This is mainly useful for I2S systems, since I2S has two phases of LRCLK the number of slots is always a multiple of 2.

2022-04-05ASoC: soc-dapm: fix two incorrect uses of list iteratorXiaomeng Tong1-4/+2
These two bug are here: list_for_each_entry_safe_continue(w, n, list, power_list); list_for_each_entry_safe_continue(w, n, list, power_list); After the list_for_each_entry_safe_continue() exits, the list iterator will always be a bogus pointer which point to an invalid struct objdect containing HEAD member. The funciton poniter 'w->event' will be a invalid value which can lead to a control-flow hijack if the 'w' can be controlled. The original intention was to continue the outer list_for_each_entry_safe() loop with the same entry if w->event is NULL, but misunderstanding the meaning of list_for_each_entry_safe_continue(). So just add a 'continue;' to fix the bug.

CATPT_SSP_IFACE_LAST is being used only to calculate CATPT_SSP_COUNT. Make CATPT_SSP_COUNT part of the enum directly and remove the redundant constant. Signed-off-by: Cezary Rojewski <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Mark Brown <[email protected]>
