Currently the following errors are seen: [ 14.015056] mc13xxx 0-0008: Failed to read IRQ status: -6 [ 27.321093] mc13xxx 0-0008: Failed to read IRQ status: -6 [ 27.411681] mc13xxx 0-0008: Failed to read IRQ status: -6 [ 27.456281] mc13xxx 0-0008: Failed to read IRQ status: -6 [ 30.527106] mc13xxx 0-0008: Failed to read IRQ status: -6 [ 36.596900] mc13xxx 0-0008: Failed to read IRQ status: -6 Also when reading the interrupts via 'cat /proc/interrupts' the PMIC GPIO interrupt counter does not stop increasing. The reason for the storm of interrupts is that the PUS field of register IOMUXC_SW_PAD_CTL_PAD_CSI0_DAT5 is currently configured as: 10 : 100k pullup and the PMIC interrupt is being registered as IRQ_TYPE_LEVEL_HIGH type, which is the correct type as per the MC34708 datasheet. Use the default power on value for the IOMUX, which sets PUS field as: 00: 360k pull down This prevents the spurious PMIC interrupts from happening. Commite1ffceb078("ARM: imx53: qsrb: fix PMIC interrupt level") correctly described the irq type as IRQ_TYPE_LEVEL_HIGH, but missed to update the IOMUX of the PMIC GPIO as pull down. Fixes:e1ffceb078("ARM: imx53: qsrb: fix PMIC interrupt level") Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
