Thanks for the Quick reply.
So If I want to use different platform_data for different boards can I do something like below?
And initialize the platform data in either driver or in separate module which gets compiled along with driver?
static const struct acpi_device_id my_acpi_match[] = {
{ "MYID0001", (kernel_ulong_t)&my_platform_data1 }
{ "MYID0002", (kernel_ulong_t)&my_platform_data2 }
...
{ },
Thanks,
Ram
