Hi. I have board with SGTl5000 codec connected to DM365 via McBSP (FSR/CLKR/DX/DR), I2C and CLKOUT1.

DM365-EVM has TVL320AIC3101 connected to DM365 like SGTL5000 on my board. I try to patch DM365-EVM code but something went wrong.

There is what I do:

1. arch/arm/mach-davinci/board-dm365-evm.c

static struct i2c_board_info i2c_info[] = {{ I2C_BOARD_INFO("sgtl5000", 0x0a), }, }; ... i2c_register_board_info(1, i2c_info, ARRAY_SIZE(i2c_info)); ... prepare_enable(clkout1_clk); __raw_writel(__raw_readl(davinci_sysmod_base + 0x0d48) | 0x00000002, davinci_sysmod_base + 0x0d48); __raw_writel(0, davinci_sysmod_base + 0x0d04); __raw_writel(0x8000, davinci_sysmod_base + 0x0d24); // 24/1=> 24Mhz

2. sound/soc/codecs/sgtl5000.c - removed mclk-related code

3. sound/soc/davinci/davinci-evm.c - all AIC3x data structures changed to sgtl5000

I know that I need to copy davinci-evm to different file and that work with it. I patch davinci-evm only for test purposes.

There is a questions:

1. I need a right way to describe clock source for sgtl5000.

2. During kernel initialization I see output:

Registering platform device 'davinci-mcbsp'. Parent at platform Advanced Linux Sound Architecture Driver Initialized. sgtl5000-codec 1-000a: sgtl5000 revision 0x11 Registering platform device 'soc-audio.0'. Parent at platform soc-audio soc-audio.0: ASoC: machine DaVinci DM365 EVM should use snd_soc_register_card() soc-audio soc-audio.0: ASoC: CPU DAI davinci-mcbsp not registered platform soc-audio.0: Driver soc-audio requests probe deferral soc-audio: probe of soc-audio.0 failed with error -22 ALSA device list: No soundcards found.

I don't know what I need to do with "ASoC: machine DaVinci DM365 EVM should use snd_soc_register_card()" (may be, just ignore?) and "ASoC: CPU DAI davinci-mcbsp not registered" (looks like a problem).

May be anyone has step-by-step tutorial?

Thanks. Andrew Kuksov
