In certain cases, you may wish to modify the PWMMax value used to match the specifics of your framebuffer. This is especially true if you're not using the typical ig-platform-id and your ig-platform-id uses a different PWMMax.
One example would be Haswell ig-platform-id 0xa2e0008, which uses 0x56c instead of the typical 0xad9 (as used by 0xa260006).
In this case you will need to provide a custom LMAX, since the PWMMax determined based on device-id will not match your ig-platform-id.
This can be done by providing an SSDT-RMCF.aml in ACPI/patched. You will find SSDT-RMCF.dsl in the main guide/hotpatch repo: https://github.com/RehabMan/OS-X-Clover-Laptop-Config. Look in the 'hotpatch' folder.
I am not using a typical ig-platform-id 0x1660004 on my ivy platform, i use 0x01660008 instead. So where or how do i can find the correct PWMMax?
