They are enabled specifically on the TI OMAP4 PandaBoard and OMAP5 uEVM boards. This is the last DT piece that now completes the support for IPUs and DSPs on all OMAP4+ SoCs, similar patches were merged for 5.8 covering the DRA7xx/AM57xx SoCs. Appreciate it if you can pick up the series for 5.9 if it isn't too late. There is one issue that I have run into while testing this series on the latest kernel. I am seeing a l3_noc error for OMAP4 DSP when it attempts to auto-suspend or stop after it is booted. The issue is a L4CFG read error that happens in the sysc_disable_module() function in ti-sysc code. I do not have any issues on my downstream 5.4 based SDK kernel. I have root-caused this to the OMAP4 voltage controller patches you added for 5.5 kernel through your omap-for-v5.5/pm branch, specifically the commit 4873843718f9 ("ARM: OMAP2+: Initialize voltage controller for omap4"). The VOLTCTRL register value is 0x300 before that patch, and modifying this register either through omap4_vc_init_pmic_signaling() or omap4_vc_set_pmic_signaling() will trigger this. A debug print in sysc_disable_module() also seems to help. regards Suman Suman Anna (13): ARM: dts: omap4: Add timer_sys_ck clocks for timers ARM: dts: omap5: Add timer_sys_ck clocks for timers ARM: dts: omap4: Update the DSP node ARM: dts: omap4: Add IPU DT node ARM: dts: omap4: Add aliases for rproc nodes ARM: dts: omap4-panda-common: Add CMA pools and enable IPU & DSP ARM: dts: omap4-panda-common:: Add system timers to DSP and IPU ARM: dts: omap5: Add DSP and IPU nodes ARM: dts: omap5: Add aliases for rproc nodes ARM: dts: omap5-uevm: Add CMA pools and enable IPU & DSP ARM: dts: omap5-uevm: Add system timers to DSP and IPU ARM: dts: omap4-panda-common: Add watchdog timers for IPU and DSP ARM: dts: omap5-uevm: Add watchdog timers for IPU and DSP arch/arm/boot/dts/omap4-l4-abe.dtsi | 20 +++++++------ arch/arm/boot/dts/omap4-l4.dtsi | 35 ++++++++++++++--------- arch/arm/boot/dts/omap4-panda-common.dtsi | 34 ++++++++++++++++++++++ arch/arm/boot/dts/omap4.dtsi | 29 ++++++++++++++++--- arch/arm/boot/dts/omap5-l4-abe.dtsi | 20 +++++++------ arch/arm/boot/dts/omap5-l4.dtsi | 35 ++++++++++++++--------- arch/arm/boot/dts/omap5-uevm.dts | 34 ++++++++++++++++++++++ arch/arm/boot/dts/omap5.dtsi | 25 ++++++++++++++++ 8 files changed, 184 insertions(+), 48 deletions(-)
