Subject[RESEND PATCH v2 0/3] drivers/perf: add DDR Sub-System Driveway PMU driver for Yitian 710 SoC
Date
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
