@Subrata, I found fspUpd has PcieClkSrcUsage[18],
Its for unified FSP between ADL-S and P, thats the reason might be but you don't need more than 7 i believe
and schematic has 0-9B. Is 9B map to PcieClkSrcUsage[10]?
what is 9B ?
GPP_A12/SATAXPCIE1/SATAGP1/SRCCLKREQ9B#
looks like you have CLK REQ 9 so, PcieClkSrcUsage[9] but need to verify ur CLKSRC.
GPP_E0/SATAXPCIE0/SATAGP0/SRCCLKREQ9# This is confused because the pin is different.. Not quite understand it. Both map the same ClkSrc?
