Merge tag 'vexpress-updates-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/dt
ARMv7 Vexpress updates for v5.3
1. Couple of updates switching to use new/updated bindings for CoreSight
dynamic funnel components and NOR flash partition type
2. Disable NOR flash on Vexpress TC2 platform as it conflicts with CPU
power management. This follows what we have on ARMv8 Juno platform
and is required after recent commit that enabled CFI NOR FLASH in
multi_v7 defconfig
* tag 'vexpress-updates-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux:
ARM: dts: vexpress: set the right partition type for NOR flash
arm: dts: vexpress-v2p-ca15_a7: disable NOR flash node by default
ARM: dts: vexpress-v2p-ca15_a7: update coresight DT bindings
