I want to confirm that does the aspeed_gates is set for matching with the SoC default clock setting?

ASPEED LPC IP HW block have serval clk input.<br>
Most important is LCLK is come from LPC Host.<br>
The others is not controllable by register.<br>

The aspeed_gates in clk-aspeed.c perhaps as todo suggest asking Aspeed<br>
the actual parent data for check initializing?<o:p></o:p></span></p>

Yes, that makes sense.<br>
<br>
Hi Gary and Ryan,<br>
<br>
Can you please tell us what is the actual parent clock source of LPC IP?<br>
I mean the operational clock of LPC IP hardware block, not the interface<br>
clock.<br>
<br>
Thanks,<br>

I traced lpc-ctrl module, it seems direct update the same<br>
ASPEED_CLK_GATE_LCLK register map bit to enable. If parent data is<br>
disabled, it could enable in dts.<br>
The device tree detail, I reference it from aspeed-g5.dtsi. Hope it<br>
could help you for work.<br>

Samual/Jay,<br>
In my case if I don't initialize LPC clock in driver, Bios on host side wait and doesn't boot.<br>
I don't understand here what is holding Bios here but by initializing this LPC clock let bios boot.<br>
