Use the clock bindings for the Stratix10 SoC. This includes changing the old binding of "intc,clk-s10-mgr" to "intel,stratix10-clkmgr". The reason that this can be done is that there are currently no clock driver for Stratix10, thus there are no consumers of the old binding. So changing the binding will not break any legacy code. Signed-off-by: Dinh Nguyen <dinguyen@kernel.org> --- v6: - no changes v5: - no changes v4: - remove '_' in name of clock nodes - use clock-controller in SoCDK node in dts file v3: - use the correct vendor prefix - explain the binding change v2: - use a single clock binding for the clock controller --- arch/arm64/boot/dts/altera/socfpga_stratix10.dtsi | 50 +++++++++++++++++++++- .../boot/dts/altera/socfpga_stratix10_socdk.dts | 10 +++++ 2 files changed, 58 insertions(+), 2 deletions(-)
