Subject: [PATCH 0/4] ARM64: dts: meson: hhi syscon and clock controllers
Date: Thu, 15 Mar 2018 12:55:41 +0100 [thread overview]
Message-ID: <20180315115545.1884-1-jbrunet@baylibre.com> (raw)
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]
