[PATCH v2 0/3] irqchip/sg2042-msi: Set irq type according to DT configuration

[Chen Wang]

Hi, Thomas,

Would you please pick this patchset?

P.S. Since the modification of the DTS part is closely dependent on the 
modification of the driver part, I am not sure whether you are willing 
to pick these three patches together, or just pick the driver part and 
leave the DTS part to me?

Thanks,

Chen
