Observed kernel log messages: ti-sysc 44e31000.target-module: Failed to create device link (0x180) with supplier ocp for /ocp/interconnect@44c00000/segment@200000/target-module@31000/timer@0 ti-sysc 48040000.target-module: Failed to create device link (0x180) with supplier ocp for /ocp/interconnect@48000000/segment@0/target-module@40000/timer@0 The change updates dependency handling for timer1 and timer2 so the kernel no longer attempts this invalid link-creation path during initialization of supplier ocp. Impact: - Removes the two ti-sysc/fw_devlink error messages at boot - Preserves current timer and clock assignment behavior - No functional regression observed in boot and timer operation tests Signed-off-by: Wagner Popov dos Santos --- arch/arm/boot/dts/ti/omap/am33xx.dtsi | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/arm/boot/dts/ti/omap/am33xx.dtsi b/arch/arm/boot/dts/ti/omap/am33xx.dtsi index ca3e7f5d7d0d..760598d5ae1c 100644 --- a/arch/arm/boot/dts/ti/omap/am33xx.dtsi +++ b/arch/arm/boot/dts/ti/omap/am33xx.dtsi @@ -708,6 +708,7 @@ &timer1_target { timer@0 { assigned-clocks = <&timer1_fck>; assigned-clock-parents = <&sys_clkin_ck>; + post-init-providers = <&ocp>; }; }; @@ -721,5 +722,6 @@ &timer2_target { timer@0 { assigned-clocks = <&timer2_fck>; assigned-clock-parents = <&sys_clkin_ck>; + post-init-providers = <&ocp>; }; }; -- 2.43.0 ------=_Part_19_261743831.1782392122149--
