This patchset adds support for the SDEI path. I do have a patch to enable the interrupt path as well but I'm holding it back since AGDI table is missing interrupt configuration fields (trigger type etc.). The recently published specification is available at https://developer.arm.com/documentation/den0093/latest The patchset was tested on Ampere Altra/Mt. Jade. The patchset applies on top of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm bleeding-edge (642439a44411) From v1: * Moved pdata to the stack and dropped unnecessary kzalloc() in agdi_init() * Changed the ACPICA patch upstreaming order comment in the paragraph above From v2: * The first patch was split. The most of it was merged to ACPICA project at first and later ported to linux-acpi (fd919e37cb15914c6fe13e13d530a4f732407c6d). The rest are in the first patch.
