[参考译文] TLV320AIC3254-Q1：TLV320AIC3254-Q1启动问题

日志是否与上次相同？ 您可以共享日志吗？

谢谢

凯文

尊敬的 Kevin：  

是的、日志相同、  不会触发 aic32x4_i2c_probe

平台供应商表示

"MCLK 已启用，您不必在编解码器驱动器中进行修改"

这意味着我们不需要 在 dtsi 时添加时钟

e2e.ti.com/.../no_5F00_sound_5F00_cards.txt

该问题与 QCOM 平台中的时钟设置有关、我们没有该信息、您可以从 \arch\arm64\boot\dts\Qcom\中搜索该信息、应该有很多参考资料可供您参考。

如果器件树时钟出现故障、则只能手动设置 PLL 的 PARTNER_RATE 和 RATE

谢谢

凯文

尊敬的 Kevin

"只能手动设置 PLL 的 PARTNER_RATE 和 RATE "

=>是否是  在编解码器驱动程序中创建和配置父级？

可以以及如何  在 aic32x4_register_clocks()初始化父项

非常感谢

您是否可以尝试在 aic32x4_clkdesc_array[]中添加"MCLK"&"BCLK" ？  

static struct aic32x4_clkdesc aic32x4_clkdesc_array[] = {
	{
		.name = "pll",
		.parent_names =
			(const char* []) { "mclk", "bclk", "gpio", "din" },
		.num_parents = 4,
		.ops = &aic32x4_pll_ops,
		.reg = 0,
	},
	{
		.name = "codec_clkin",
		.parent_names =
			(const char *[]) { "mclk", "bclk", "gpio", "pll" },
		.num_parents = 4,
		.ops = &aic32x4_codec_clkin_ops,
		.reg = 0,
	},
	{
		.name = "ndac",
		.parent_names = (const char * []) { "codec_clkin" },
		.num_parents = 1,
		.ops = &aic32x4_div_ops,
		.reg = AIC32X4_NDAC,
	},
	{
		.name = "mdac",
		.parent_names = (const char * []) { "ndac" },
		.num_parents = 1,
		.ops = &aic32x4_div_ops,
		.reg = AIC32X4_MDAC,
	},
	{
		.name = "nadc",
		.parent_names = (const char * []) { "codec_clkin" },
		.num_parents = 1,
		.ops = &aic32x4_div_ops,
		.reg = AIC32X4_NADC,
	},
	{
		.name = "madc",
		.parent_names = (const char * []) { "nadc" },
		.num_parents = 1,
		.ops = &aic32x4_div_ops,
		.reg = AIC32X4_MADC,
	},
	{
		.name = "bdiv",
		.parent_names =
			(const char *[]) { "ndac", "mdac", "nadc", "madc" },
		.num_parents = 4,
		.ops = &aic32x4_bdiv_ops,
		.reg = AIC32X4_BCLKN,
	},
	{
		.name = "mclk",
	},
	{
		.name = "bclk",
	},
};

Daniel、您好！

您能否告诉我 您方面的最新情况？  

凯文

尊敬的 Kevin

在驱动器处添加这两个 clk 后、我出现以下寄存器错误

我将对其进行调试

Daniel、您好！

看起来 像是调用了空指针、您必须添加一些内容。

	{
		.name = "mclk",
		.parent_names = (const char *[]) {},
		.num_parents = 0,
		.ops = NULL,
		.reg = 0,
	},
	{
		.name = "bclk",
		.parent_names = (const char *[]) {},
		.num_parents = 0,
		.ops = NULL,
		.reg = 0,
	},

如果需要、我们可以设置调试目录。
