Subject: [PATCH] MIPS:DTS:Fix label name and interrupt number of ohci for Loongson-2K
Date: Fri, 23 Apr 2021 09:52:34 +0800 [thread overview]
Message-ID: <20210423015234.23870-1-maoxiaochuan@loongson.cn> (raw)
from Loongson-2K1000 user manual know that under pci bus
the device num is 4, function number is 2 and register is 0x2200
is ohci. the ohci interrupt number is 51. because Loongson-2K1000 has
64 interrupt sources, 0-31 correspond to the device tree liointc0 device
node, and the other correspond to liointc1 node. so it should be
number 19 correspon to liointc1.
