Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (62 commits) powerpc/85xx: Fix signedness bug in cache-sram powerpc/fsl: 85xx: document cache sram bindings powerpc/fsl: define binding for fsl mpic interrupt controllers powerpc/fsl_msi: Handle msi-available-ranges better drivers/serial/ucc_uart.c: Add of_node_put to avoid memory leak powerpc/85xx: Fix SPE float to integer conversion failure powerpc/85xx: Update sata controller compatible for p1022ds board ATA: Add FSL sata v2 controller support powerpc/mpc8xxx_gpio: simplify searching for 'fsl, qoriq-gpio' compatiable powerpc/8xx: remove obsolete mgsuvd board powerpc/82xx: rename and update mgcoge board support powerpc/83xx: rename and update kmeter1 powerpc/85xx: Workaroudn e500 CPU erratum A005 powerpc/fsl_pci: Add support for FSL PCIe controllers v2.x powerpc/85xx: Fix writing to spin table 'cpu-release-addr' on ppc64e powerpc/pseries: Disable MSI using new interface if possible powerpc: Enable GENERIC_HARDIRQS_NO_DEPRECATED. powerpc: core irq_data conversion. powerpc: sysdev/xilinx_intc irq_data conversion. powerpc: sysdev/uic irq_data conversion. ... Fix up conflicts in arch/powerpc/sysdev/fsl_msi.c (due to getting rid of of_platform_driver in arch/powerpc)
