Subject: [PATCH] tty: serial: uartlite: allow 64 bit address

Git-commit: 3672fb65155530b5eea6225685c75329b6debec3

Patch-mainline: v5.17-rc1

References: git-fixes

The base address of uartlite registers could be 64 bit address which is from

device resource. When ulite_probe() calls ulite_assign(), this 64 bit

address is casted to 32-bit. The fix is to replace "u32" type with

"phys_addr_t" type for the base address in ulite_assign() argument list.
