Revision 9a5e3f27d1b8ca349b79e8b5fe1874eeeedb6f45 authored by Kishon Vijay Abraham I on 04 September 2015, 12:08:24 UTC, committed by Tony Lindgren on 24 September 2015, 23:28:32 UTC
"ARM: dts: <omap2/omap4/omap5/dra7>: add minimal l4 bus layout with control module support" moved pbias_regulator dt node from being a child node of ocp to be the child node of 'syscon'. Since 'syscon' doesn't have the 'ranges' property, address translation fails while trying to convert the address to resource. Fix it here by populating 'ranges' property in syscon dt node. Fixes: 72b10ac00eb1 ("ARM: dts: omap24xx: add minimal l4 bus layout with control module support") Fixes: 7415b0b4c645 ("ARM: dts: omap4: add minimal l4 bus layout with control module support") Fixes: ed8509edddeb ("ARM: dts: omap5: add minimal l4 bus layout with control module support") Fixes: d919501feffa ("ARM: dts: dra7: add minimal l4 bus layout with control module support") Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> [tony@atomide.com: fixed omap3 pbias to work] Signed-off-by: Tony Lindgren <tony@atomide.com>
