Hello,
I have a custom board with imx6dp, I connected an external oscillator of 32MHz to RTC_XTALI pin . I know that when the imx6 detects this signal comming from the XTALI it uses automatically this external clock. I have three questions:
1- how does this affect the device tree configuration?
I found in internet this config of the sabreauto board:
| clocks { |
| codec_osc: anaclk2 { |
| compatible = "fixed-clock"; |
| #clock-cells = <0>; |
| clock-frequency = <24576000>; |
| }; |
| }; |
but it confuses me beacuse the oscillator for the board is of 28MHz not 24 as can be seen in the layout of the board.
2- When I use the clock from the ESAI interface, is it taking this frequency for the ESAI_TX_HF_CLK??
3- In the imx6qdl-clock.h it gives different clock values, but what does it mean the number , what is the frequency for each one of the definitions?
I have read different documents, please dont refere me to read I will appreciate a clear answer :smileyhappy:
Thanks in advance
Kind regards.
