But QUSB2 Phy based targets have another interrupt which gets triggered in response to J/K states on dp/dm pads. Its functionality is replaced by dp/dm interrupts on Femto/m31/eusb2 phy based targets for wakeup purposes. Exceptions are some targets like SDM845/SDM670/SM6350 where dp/dm irq's are used although they are qusb2 phy targets. Currently in QUSB2 Phy based DT's, te qusb2_phy interrupt is named and used as "hs_phy_irq" when in fact it is a different interrupt (used by HW validation folks for debug purposes and not used on any downstream target qusb/non-qusb). On some non-QUSB2 targets (like sm8450/sm8550), the pwr_event IRQ was named as hs_phy_irq and actual pwr_event_irq was skipped. This series tries to address the discrepancies in the interrupt numbering adding the missing interrupts and correcting the existing ones. This series has been compared with downstream counter part and hw specifics to ensure the numbering is right. Since there is not functionality change the code has been only compile tested. Changes in v5: Fixed commit header on v4-1 bindings patch. Provide lore link instead of patchwork link for v3. Changes in v4: Udpated commit text indicating why pwr_event interrupt was added as the first one and fixed some typos present in v3. While at it, rebase on top of latest linux-next fixing merge conflicts. Changes in v3: Separated out the DT changes and pushed only bindings and driver update. Modified order of irq descriptions to match them with permutations defined. Fixed nitpicks mentioned by reviewers in v2. Changes in v2: Removed additional compatibles added for different targets in v1. Specified permuations of interrupts possible for QC targets and regrouped interrupts for most of the DT's.
