| Subject: dt-bindings: power: reset: qcom-pon: Only allow reboot-mode |
| pre-pmk8350 |
| |
| From: Konrad Dybcio <konrad.dybcio@linaro.org> |
| |
| [ Upstream commit d41dab4c031edaa460a484113394327aa52dc0bd ] |
| |
| As pointed out by Shazad [1], PMICs using a separate HLOS+PBS scheme |
| (so PMK8350 and newer) are expected to pass reboot mode data through SDAM, |
| as the reboot mode registers are absent in the HLOS reg space. |
| |
| Limit the reboot-mode.yaml inclusion to PMICs without a separate PBS |
| region. |
