Using it:
---------
If you're on a MacBook8,1 (2015) you may need the `irqpoll` kernel parameter. To get this driver to work on all other MacBooks and MacBook Pros, you'll need to boot the kernel with `intremap=nosid` if you're running a kernel before 4.11. In all cases make sure you don't have `noapic` in your kernel options.
If you're on a MacBook8,1 (2015) you will need to use `spi_pxa2xx_pci` instead of `intel_lpss_pci`. To get this driver to work on all other MacBooks and MacBook Pros, you'll need to boot the kernel with `intremap=nosid` if you're running a kernel before 4.11. In all cases make sure you don't have `noapic` in your kernel options.

On the 2015 MacBook you need to (re)compile your kernel with `CONFIG_X86_INTEL_LPSS=n` if running a kernel before 4.14. On all kernels you need ensure the `spi_pxa2xx_platform` module is loaded (if you don't have that module, rebuild your kernel with `CONFIG_SPI_PXA2XX=m`).

On all other MacBook's and MacBook Pros you need to make sure both the `spi_pxa2xx_platform` and `intel_lpss_pci` modules are loaded (if these don't exist, you need to (re)compile your kernel with `CONFIG_SPI_PXA2XX=m` and `CONFIG_MFD_INTEL_LPSS_PCI=m`).
