Ruan Jinjie	2f54db449b	irqchip/imx-mu-msi: Do not check for 0 return after calling platform_get_irq() ... It is not possible for platform_get_irq() to return 0. Use the return value from platform_get_irq().

Frank Li	e4a7e67a08	irqchip/imx-mu-msi: Fix wrong register offset for 8ulp ... Offset 0x124 should be for IMX_MU_TSR, not IMX_MU_GSR.

Frank Li	70afdab904	irqchip: Add IMX MU MSI controller driver ... The MU block found in a number of Freescale/NXP SoCs supports generating IRQs by writing data to a register. This enables the MU block to be used as a MSI controller, by leveraging the platform-MSI API.
