Merge tag 'omap-for-v5.5/dt-late-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/dt
Few late dts changes for omaps for v5.5 merge window Let's configure omap3 rng as we can now easily do it with a dts change only by tagging it with status = "disabled" for n900 where it's not accessible. This improves the boot-up time with distros quite a bit with proper entropy source around. There's also another minor update for logicpd-torpedo that does not have USB host pins wired. * tag 'omap-for-v5.5/dt-late-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: logicpd-torpedo: Disable USB Host ARM: dts: Configure omap3 rng Link: https://lore.kernel.org/r/pull-1573579927-542764@atomide.com Signed-off-by: Olof Johansson <olof@lixom.net>
