This patch series include following cleanup changes in GB Audio driver. - Avoid unnecessary checks for le32 variables - Initialize sig_bits before configuring hw_params - Remove junk codec register mapping - Ensure proper byte ordering
Next task is to enable build for GB codec driver. However this requires pushing some changes in ASoC framework. Possibly in another two weeks (based on my freetime), I'll try to submit those changes to ASoC mailing list. And once the same are accepted there, I'll share relevant patches for GB Audio codec driver as well.
Changes from v1: - Include review comments from Dan
Vaibhav Agarwal (4): staging: greybus: audio: Avoid less than zero check for le32 variable staging: greybus: audio: Initialize sig_bits before configuring hwparams staging: greybus: audio: Cleanup junk codec registers staging: greybus: audio: Ensure proper byte order

mixer control->info call back function checks for -ve values to rebase min and max values. However, le32 variable is used to fetch values from GB module FW. Thus -ve value checking is not required. Fix this!!

nit: Please spell out "negative" so it is as easy as possible for the casual observer to understand what you're saying.

Uninitialized variable sig_bits was used while configuring stream params for codec module. These params are used to configure PCM settings for APBridgeA.
Usually, this is dependent on codec capability and thus populated via codec dai_driver definition. In our case, it is fixed to 16 based on the data format, container supported.

From: Vaibhav Agarwal vaibhav.agarwal@linaro.org
Dummy codec register were initially added while populating dummy codec mixer controls until module topology parser was available. Now, these dummy registers are nowhere used and thus can be safely removed.
Since ASoC framework requires a valid callback for both read & write register APIS, currently empty placeholders are kept to avoid panic.
Later, register mapping logic can be defined: 1. Assuming fixed number of maximum modules connected and register bits corresponds to basic info of each module OR 2. With a logic to dynamically grow register_cache_size based on codec modules added/removed.

Proper byte order was completely disregarded for multi byte data shared between AP and module (and APB1). Fix this.

Proper byte order was completely disregarded for multi byte data shared between AP and module (and APB1). Fix this.

Hi Vaibhav.
I think you got them all except for this one in audio_topology.c:gbcodec_mixer_dapm_ctl_put():
max = info->value.integer.max; <<<
mask = (1 << fls(max)) - 1; val = ucontrol->value.integer.value[0] & mask; connect = !!val;

Oh Ok. I'll include this change in v3.
