This patchset adds support for Yitian 710 DDR Sub-System Driveway PMU driver, which custom-built by Alibaba Group's chip development business, T-Head.
Changes since v1: - add high level workflow about DDRC so that user cloud better understand the PMU hardware mechanism - rewrite patch description and add interrupt sharing constraints - delete event perf prefix - add a condition to fix bug in ali_drw_pmu_isr - perfer CPU in the same Node when migrating irq - use FIELD_PREP and FIELD_GET to make code more readable - add T-Head HID and leave ARMHD700 as CID for compatibility - Link: https://lore.kernel.org/linux-arm-kernel/eb50310d-d4a0-c7ff-7f1c-b4ffd919b10c@linux.alibaba.com/T/
