This adds the PMU resources necessary to get perf working with the DB5500 ASIC. Acked-by: Will Deacon <redacted> Signed-off-by: Linus Walleij <redacted> --- Reduced version not including the problematic DB8500 PMU, picking some low-hanging fruit... --- arch/arm/mach-ux500/cpu-db5500.c | 26 ++++++++++++++++++++++++-- 1 files changed, 24 insertions(+), 2 deletions(-)
