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

[Krzysztof Wilczyński]

Hello,

> Commit under Fixes assigned the value of 'linkdown_irq_regfield' for the
> J784S4 SoC as 'LINK_DOWN' which corresponds to BIT(1). However, according
> to the Technical Reference Manual and Register Documentation for the J784S4
> SoC [0], BIT(1) corresponds to "ENABLE_SYS_EN_PCIE_DPA_1" which is __NOT__
> the field for the link-state interrupt. Instead, it is BIT(10) of the
> "PCIE_INTD_ENABLE_REG_SYS_2" register that corresponds to the link-state
> field named as "ENABLE_SYS_EN_PCIE_LINK_STATE".
> 
> Hence, set 'linkdown_irq_regfield' to the macro 'J7200_LINK_DOWN' which
> expands to BIT(10) and was first defined for the J7200 SoC. Other SoCs
> already reuse this macro since it accurately represents the link-state
> field in their respective "PCIE_INTD_ENABLE_REG_SYS_2" register.

Applied to controller/j721e, thank you!
