-Subject: [PATCH v2] irqchip/versatile-fpga: Handle chained IRQs properly
-Date: Thu, 19 Mar 2020 11:34:48 +0900
-Message-Id: <20200319023448.1479701-1-mans0n@gorani.run>
-In-Reply-To: <002b72cab9896fa5ac76a52e0cb503ff@kernel.org>
-References: <002b72cab9896fa5ac76a52e0cb503ff@kernel.org>
-MIME-Version: 1.0
-List-Id: <linux-arm-kernel.lists.infradead.org>
-Cc: Sungbo Eo <mans0n@gorani.run>, Neil Armstrong <narmstrong@baylibre.com>
-Sender: "linux-arm-kernel" <linux-arm-kernel-bounces@lists.infradead.org>
-
-Enclose the chained handler with chained_irq_{enter,exit}(), so that the
-muxed interrupts get properly acked.
-
-This patch also fixes a reboot bug on OX820 SoC, where the jiffies timer
-interrupt is never acked. The kernel waits a clock tick forever in
-calibrate_delay_converge(), which leads to a boot hang.
-
-Fixes: c41b16f8c9d9 ("ARM: integrator/versatile: consolidate FPGA IRQ handling code")
-Signed-off-by: Sungbo Eo <mans0n@gorani.run>
-Cc: Neil Armstrong <narmstrong@baylibre.com>

-Subject: [PATCH] irqchip/versatile-fpga: Apply clear-mask earlier
-Date: Sat, 21 Mar 2020 22:38:42 +0900
-Message-Id: <20200321133842.2408823-1-mans0n@gorani.run>

-
-Clear its own IRQs before the parent IRQ get enabled, so that the
-remaining IRQs do not accidentally interrupt the parent IRQ controller.
-
-This patch also fixes a reboot bug on OX820 SoC, where the remaining
-rps-timer IRQ raises a GIC interrupt that is left pending. After that,
-the rps-timer IRQ is cleared during driver initialization, and there's
-no IRQ left in rps-irq when local_irq_enable() is called, which evokes
-an error message "unexpected IRQ trap".
-
-Fixes: bdd272cbb97a ("irqchip: versatile FPGA: support cascaded interrupts from DT")
