Merge tag 'renesas-soc-fixes-for-v3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into fixes
Merge "Renesas ARM Based SoC Fixes for v3.19" from Simon Horman: Renesas ARM Based SoC Fixes for v3.19 This pull request is based on the last round of SoC updates for v3.19, Fourth Round of Renesas ARM Based SoC Updates for v3.19, tagged as renesas-soc3-for-v3.19, merged into your next/soc branch and included in v3.19-rc1. - ARM: shmobile: r8a7740: Instantiate GIC from C board code in legacy builds Set .control_parent for all irqpin instances for sh73a0 SoC when booting using legacy C. - ARM: shmobile: r8a7740: Instantiate GIC from C board code in legacy builds This fixes a long standing problem which has been present since the sh73a0 SoC started using the INTC External IRQ pin driver. The patch that introduced the problem is 341eb5465f67437a ("ARM: shmobile: INTC External IRQ pin driver on sh73a0") which was included in v3.10. * tag 'renesas-soc-fixes-for-v3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas: ARM: shmobile: sh73a0 legacy: Set .control_parent for all irqpin instances ARM: shmobile: r8a7740: Instantiate GIC from C board code in legacy builds
