Cover letter [PATCH v4 0/4] nds32: Perf support
These four commits are perf supporting for nds32. There are three perfomance counters in nds32, and each of them can counts different events. You can use 'perf list' to show the available events that can be used.
Changes in V2:
1. Change the definition 'PFM_CTL_xxx' to
array form.
2. Simplify the PMU driver.
3. Stop all counters when handling irq
caused by performance counters overflow.
4. Rename the compatible string in
devicetree.
Changes in V3:
Fix the typo in Documentation/devicetree/bindings/nds32/pmu.txt.
Changes in V4:
Move 'Documentation/devicetree/bindings/nds32/pmu.txt'
to 'Documentation/devicetree/bindings/perf/nds32v3-pmu.txt'.
Nickhu (4):
nds32: Fix bug in bitfield.h
nds32: Perf porting
nds32: Add perf call-graph support.
nds32: Add document for NDS32 PMU.
