Subject: [PATCH] drm/vc4: Fix VEC address for BCM2711 in the
devicetrees
The VEC has a different address (0x7ec13000) on the BCM2711 (used in
e.g. Raspberry Pi 4) compared to BCM238x (e.g. Pi 3 and earlier). This
was erroneously not taken account for.
Definition of the VEC in the devicetrees had to be moved from
bcm283x.dtsi to bcm2711.dtsi and bcm2835-common.dtsi to allow for this
differentiation.
