When creating an IRQ domain, the code used to store a device struct pointer in the `of_node` field of the irq_domain struct returned by `irq_domain_add_linear`. This was done by casting to a void pointer and passing as the first argument of the function. In the SPEC repository (and supposedly other depending repositories), we would then get back the irq_domain struct by calling `irq_find_host` with again a device struct pointer casted to a void pointer as the argument. The function would compare the addresses of the 2 device structs and return the right irq_domain. This trick was most likely due to the fact that the IRQ domain API was conceived around OpenFirmware before version 4.4, and that the project should work for ACPI. A workaround for kernel 4.7 was written, which involved using a `select` function, and passing the address of the device struct as a parameter. It was particularly ugly as it would require getting around the `irq_find_host` to call immediately `irq_find_matching_fwspec` and pass in the address of the wanted device struct as a parameter in a hacky way to fit it inside two 32 bit integers. Kernel version 4.4 introduced fwnodes, which would make easier working with ACPI. Instead of repeating the hacky workaround (which would result in a kernel error on later kernels when calling irq_domain_add_linear), I allocated a fwnode_handle struct before creating a new IRQ domain. Then I used the new irq_domain_create_* API to get an irq_domain using this fwnode. I also took care of disallocating the fwnode_handle. On the other end, we can just call `irq_find_matching_fwnode` and pass dev.fwnode as a parameter.

`i2c_new_device` disappeared in kernel 5.2 and onwards. It is now required to use `i2c_new_client_device`, which works the same way except for error checking. Signed-off-by: Mathis MARION <mathis.marion@grenoble-inp.org>

Adding condition to warn about 0 divider value. It was observed while accessing svec-flash, if frequency for flash is not defined correctly i.e in operation range of chip and host(i.e vme or pci), divider value 0 doesn't allow flash transfers.

So that in one read access, the software can read both the status and the value and can decide if the value is correct. This avoids race issues.

The goal is to make sure that files in the common directory don't depend on things defined elsewhere. With these changes, the only remaining issue is gc_delay_line that uses generic_dpram from genrams Signed-off-by: Olof Kindgren <olof.kindgren@gmail.com>
