Date: Mon, 9 Jul 2012 14:13:03 +0530 Message-ID: <1341823383-15510-1-git-send-email-Varun.Sethi@freescale.com> MIME-Version: 1.0 Content-Type: text/plain Cc: Varun Sethi List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , This patchset adds/fixes the following functionality specific to the FSL MPIC: 1. Fix support for timer group B interrupts. Previously these were not getting initialized. 2. Use the MPIC_LARGE_VECTORS flag while intializing FSL MPIC. This prevents us from eating in to hardware vector number space (MSIs) while setting up internal sources. 3.Cascaded handling for the MPIC error interrupt. This is possible with FSL MPIC version >= 4.1. The patches are based on "next" branch of Benjamin Herrenschmidt's powerpc linux tree. Varun Sethi (3): Support time group b on freescale chips. Use MPIC_LARGE_VECTORS flag for Freescale MPIC. Add support for cascaded error interrupt handling. arch/powerpc/include/asm/mpic.h | 22 ++++ arch/powerpc/sysdev/Makefile | 2 +- arch/powerpc/sysdev/fsl_mpic_err.c | 157 ++++++++++++++++++++++++++++++ arch/powerpc/sysdev/mpic.c | 95 +++++++++++++++---- arch/powerpc/sysdev/mpic.h | 22 ++++ 6 files changed, 338 insertions(+), 19 deletions(-) create mode 100644 arch/powerpc/sysdev/fsl_mpic_err.c -- 1.7.2.2
