[ Upstream commit ce48af13e6381772cc27676be63a6d9176c14a49 ]
The base address of JPEG decoder core 1 should start at 0x10000, and have a size of 0x10000, i.e. it is right after core 0.
Instead the core has the same base address as core 0, and with a crazy large size. This looks like a mixup of address and size cells when the ranges were converted.
This causes the kernel to fail to register the second core due to sysfs name conflicts:
sysfs: cannot create duplicate filename '/devices/platform/soc/soc:jpeg-decoder@1a040000/1a040000.jpgdec'
Fix up the address range.
