[alsa-devel] [PATCH V2 0/2] ALSA: ASoC for Au1000/1500/1100
by Manuel Lauss 22 Jul '11

22 Jul '11

Hello, These 2 patches implement ASoC drivers for the AC97 and I2S controllers found on early Alchemy chips. They are largely based on the old mips/au1x00.c driver which they replace. AC97 Tested on a Db1500 development board; I2S untested since none of the testboards I have actually have an I2S codec (just testpoints). Changes since V1: - added untested I2S controller driver for completeness, removed the audio defines from the au1000 header.

[alsa-devel] [PATCH V2 0/4] Add Samsung internal dma driver support
by Sangbeom Kim 21 Jul '11

21 Jul '11

I2S in samsung audio subsytem has a small internal dma(idma). IDMA can be used in low power audio mode and I2S0 secondary fifo data tranfer. In this patchsets, idma driver is added. Original code is made by jassi brar on SMDKV210 After idma driver merge, I will submit low power audio support with idma driver and samsung dsp driver. Changes since v1: 1. Change idma_new by new pcm_new api 2. Add handling different idma address 3. As jassi comments, Modify the idma driver This patchset contains followings o To Jassi Brar, Mark Brown and Liam Girdwood, [PATCH V2 1/4] ASoC: SAMSUNG: Modify I2S driver to support idma [PATCH V2 2/4] ASoC: SAMSUNG: Add I2S0 internal dma driver o To Kukjin Kim [PATCH V2 3/4] ARM: SAMSUNG: Add platform device for idma [PATCH V2 4/4] ARM: SAMSUNG: Add IRQ_I2S0 definition Thanks SB Kim

A similar issue applied to some of the other stuff but this is the most obvious example. I'd suggest restructuring this to have all the mono-specific code in an if statement that postively selects for the feature. > if (aic3x->model == AIC3X_MODEL_3007) > snd_soc_add_controls(codec, &aic3x_classd_amp_gain_ctrl, 1); > - > + else > + snd_soc_add_controls(codec, aic3x_mono_controls, > + ARRAY_SIZE(aic3x_mono_controls)); This if ... else should really be a switch.
