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. Commit |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
