Subject: [PATCH 0/4] ARM64: dts: meson: hhi syscon and clock controllers

The HHI register region provides more than just clocks. Several drivers may
need to access this region, such as the clock controllers and the display
driver.

Meson-gx clock controllers has been developed and merged before we knew the
hhi could be needed elsewhere, which is why it requests the region directly.
Meson-axg was built following the model of meson-gx.

To fix this situation, the clock controller should be a child of the hhi
system controllers. The hhi system controller node already exists on meson-gx.
It needs to be added on the axg.

This changeset depends on [0]. This dependency has been merged in
clk-next. A topic branch is available here [1]

Jerome Brunet (4):
  dt-bindings: clock: meson: update documentation with hhi syscon
  ARM64: dts: meson-gx: sysctrl is the parent of the clock controller
  ARM64: dts: meson-axg: use hhi syscon for the clock controller
  ARM64: dts: meson-gx: fix gxl clock controller compatible
