The A31 and later have an R_INTC block which handles the NMI interrupt pin on the SoC. This interrupt pin is used by the external PMIC to signal interrupts to the SoC. While this hardware block is undocumented, the interrupt offsets combined with the register regions for the existing "sun6i-a31-sc-nmi" compatible line up with the old interrupt controller found on the A10. Experiments show that only the first 32 interrupt lines can be enabled, and only the first (NMI) interrupt is actually connected. This patch adds a new, properly named compatible for the A31 R_INTC block, which requires the register region to be properly aligned to the block boundary. For comparison, the old "sun6i-a31-sc-nmi" compatible had its register region aligned with the first used register. This didn't match up with the memory map in the SoC's datasheet/user manual. Since the new compatible supercedes the old one, deprecate the old one. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> |

README
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.
