Hi,
Changes in this set compared to v3:
- Changed the SCM module DT node layout based on comments from Tony;
basically the wkup / core are split into their own nodes now. This
applies for omap3, omap4, omap5 and dra7, rest of the SoCs have their
control module integrated as one instance (Patch 26, 30, 33, 34)
- Changed the tisyscon node name to scm_conf. This name is more
descriptive for the purpose being used, scm_conf was already used
as an alias (Patch 24, 25, 27, 29)
- Rest of the patches have no changes compared to v3.
Testing done:
- am335x-evm : boot
- am335x-evmsk : boot
- am3517-evm : boot
- am43x-epos-evm : boot
- am437x-gp-evm : boot
- omap3-beagle-xm : boot
- omap3-beagle : boot, suspend-resume (ret/off), cpuidle (ret/off)
- am335x-boneblack: boot
- am335x-bone : boot
- dra7xx-evm : boot
- omap3-n900 : boot
- omap5-uevm : boot
- omap4-panda-es : boot, suspend-resume (ret), cpuidle (ret)
- omap4-panda : boot
- omap2430-sdp : boot
- omap3430-sdp : boot
- omap4-sdp-es23plus: boot
Test branch pushed at:
- tree: https://github.com/t-kristo/linux-pm.git
- branch: 4.0-rc1-prcm-cleanup-v4
Boots for me also for 2430-sdp.
But for dm8168-evm, it fails early on, see below.
Yea seems I forgot to add dm81x support properly. Try this diff:
