Subject: Re: [PATCH] PCI: j721e: Fix the value of linkdown_irq_regfield for J784S4

Hello,

Can you confirm for me that the following use the correct macro?

  333-static const struct j721e_pcie_data j721e_pcie_rc_data = {
  337:	.linkdown_irq_regfield = LINK_DOWN,
  
  341-static const struct j721e_pcie_data j721e_pcie_ep_data = {
  343:	.linkdown_irq_regfield = LINK_DOWN,
  
  347-static const struct j721e_pcie_data j7200_pcie_rc_data = {
  350:	.linkdown_irq_regfield = J7200_LINK_DOWN,
  
  362-static const struct j721e_pcie_data am64_pcie_rc_data = {
  364:	.linkdown_irq_regfield = J7200_LINK_DOWN,
  
  369-static const struct j721e_pcie_data am64_pcie_ep_data = {
  371:	.linkdown_irq_regfield = J7200_LINK_DOWN,
  
  375-static const struct j721e_pcie_data j784s4_pcie_rc_data = {
  379:	.linkdown_irq_regfield = LINK_DOWN,
  
  383-static const struct j721e_pcie_data j784s4_pcie_ep_data = {
  385:	.linkdown_irq_regfield = LINK_DOWN,
  
  389-static const struct j721e_pcie_data j722s_pcie_rc_data = {
  391:	.linkdown_irq_regfield = J7200_LINK_DOWN,

I am asking as some use LINK_DOWN, so I wanted to make sure.

Tht said, the following has no .linkdown_irq_regfield property set:

  355-static const struct j721e_pcie_data j7200_pcie_ep_data = {
  356-	.mode = PCI_MODE_EP,
  357-	.quirk_detect_quiet_flag = true,
  358-	.quirk_disable_flr = true,
  359-	.max_lanes = 2,
  360-};

Would this be a problem?  Or is this as expected?

Thank you!

	Krzysztof
