Subject: [PATCH V2 3/9] ARM: tegra: Export tegra_cpuidle_pcie_irqs_in_use()
Date: Sun, 26 Nov 2017 01:02:07 +0530 [thread overview]
Message-ID: <1511638333-22951-4-git-send-email-mmaddireddy@nvidia.com> (raw)
In-Reply-To: <1511638333-22951-1-git-send-email-mmaddireddy@nvidia.com>
Tegra20 has a HW bug where PCIe interrupts are lost when LP2 (Tegra idle
state) is enabled. tegra_cpuidle_pcie_irqs_in_use() disables LP2 when
PCIe irq is mapped. EXPORT tegra_cpuidle_pcie_irqs_in_use() to allow Tegra
PCIe driver to be compiled as loadable kernel module.
