Date: Fri, 14 Feb 2020 10:56:50 -0500 From: Sasha Levin <sashal@...nel.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Andre Przywara <andre.przywara@....com>, Maxime Ripard <maxime@...no.tech>, Sasha Levin <sashal@...nel.org>, linux-arm-kernel@...ts.infradead.org, devicetree@...r.kernel.org Subject: [PATCH AUTOSEL 5.4 160/459] arm64: dts: allwinner: H5: Add PMU node From: Andre Przywara <andre.przywara@....com> [ Upstream commit c35a516a46187c8eeb7a56c64505ec6f7e22a0c7 ] Add the Performance Monitoring Unit (PMU) device tree node to the H5 .dtsi, which tells DT users which interrupts are triggered by PMU overflow events on each core. As with the A64, the interrupt numbers from the manual were wrong (off by 4), the actual SPI IDs have been gathered in U-Boot, and were verified with perf in Linux. Tested with perf record and taskset on an OrangePi PC2.
