AM3517 inherits OMAP3 dts file, but does not have all the IPs that are present on OMAP3. This patch disables the following absent IPs for AM3517: Mailbox, IVA, MMU_ISP, MPU_IVA SmartReflex. A label had to be added for IVA node in omap3.dtsi to be able to get a reference to the node for disabling. Otherwise we get the following warnings during booting: platform iva.2: Cannot lookup hwmod 'iva' platform 48094000.mailbox: Cannot lookup hwmod 'mailbox' platform 480bd400.mmu: Cannot lookup hwmod 'mmu_isp' platform 480c9000.smartreflex: Cannot lookup hwmod 'smartreflex_mpu_iva' Signed-off-by: Suman Anna <s-anna@ti.com> [tony@atomide.com: updated description for the warnings] Signed-off-by: Tony Lindgren <tony@atomide.com>
