Note, your subject line says 00/14 yet your patches had 00/09. I hope
you didn't dropp patches somewhere?
I applied what is here now, but are some missing?
thanks,

Should I upload another cover letter to fix the subject line? No, that would just confuse me more, all is good now, thanks. greg k-h
From: Abdel Alkuor <abdelalkuor@geotab.com> TPS25750 USB type-C PD controller has the same register offsets as tps6598x. The following is a summary of incorporating TPS25750 into TPS6598x driver: - Add device data to accommodate different implementations - Only Check VID register (0x00) for TPS6598x and cd321x, as TPS25750 doesn't have VID register. - TypeC port registration will be registered differently for each PD controller. TPS6598x uses system configuration register (0x28) to get pr/dr capabilities. On the other hand, TPS25750 will use data role property and PD status register (0x40) to get pr/dr capabilities as TPS25750 doesn't have register 0x28 supported. - TPS25750 requires writing a binary configuration to switch PD controller from PTCH mode to APP mode which needs the following changes: - Add PTCH mode to the modes list. - Add an argument to tps6598x_check_mode to return the current mode. - Currently, tps6598x_exec_cmd has cmd timeout hardcoded to 1 second, and doesn't wait before checking DATA_OUT response. In TPS25750, patch 4CCs take longer than 1 second to execute and some requires a delay before checking DATA_OUT. To accommodate that, cmd_timeout and response_delay will be added as arguments to tps6598x_exec_cmd. - Implement applying patch sequence for TPS25750. - In pm resume callback, patch mode needs to be checked and the binary configuration should be applied if needed. - For interrupt, TPS25750 has only one event register (0x14) and one mask register (0x16) of 11 bytes each, where TPS6598x has two event and two mask registers of 8 bytes each. Both TPS25750 and TPS65986x shares the same bit field offsets for events/masks/clear but many of there fields are reserved in TPS25750, the following needs to be done in tps6598x_interrupt: - Read EVENT1 register as a block of 11 bytes when tps25750 is present - Write CLEAR1 register as a block of 11 bytes when tps25750 is present - Add trace_tps25750_irq - During testing, I noticed that when a cable is plugged into the PD controller and before PD controller switches to APP mode, there is a lag between dr/pr updates and PlugInsertOrRemoval Event, so a check for dr/pr change needs to be added along TPS_REG_INT_PLUG_EVENT check - Add TPS25750 traces for status and power status registers. Trace for data register won't be added as it doesn't exist in the device. - Configure sleep mode for TPS25750. v10: - PATCH 1,2: - No changes - PATCH 3: - Add Reviewed-by - PATCH 4: - Move 0004-USB-typec-tps6598x-Load-TPS25750-patch-bundle.patch to patch 6 - Reorder 0009-USB-typec-tps6598x-Refactor-tps6598x-port-registrati.patch to be patch 4 - Add Reviewed-by - PATCH 5: - Move 0005-USB-typec-tps6598x-Check-for-EEPROM-present.patch to patch 6 - Add device data for tps6598x and cd321x - PATCH 6: - Add tps25750 support and enable it by aggregating the following patches from v9: 0004-USB-typec-tps6598x-Load-TPS25750-patch-bundle.patch 0005-USB-typec-tps6598x-Check-for-EEPROM-present.patch 0006-USB-typec-tps6598x-Clear-dead-battery-flag.patch 0007-USB-typec-tps6598x-Apply-patch-again-after-power-res.patch 0008-USB-typec-tps6598x-Add-interrupt-support-for-TPS2575.patch 0010-USB-typec-tps6598x-Add-port-registration-for-tps2575.patch 0011-USB-typec-tps6598x-Enable-sleep-mode-for-tps25750.patch - PATCH 7: - Move 0012-USB-typec-tps6598x-Add-trace-for-tps25750-irq.patch to patch 7 - PATCH 8: - Move 0013-USB-typec-tps6598x-Add-power-status-trace-for-tps257.patch to patch 8 - Remove power status trace prototype from device data - PATCH 9: - Move 0014-USB-typec-tps6598x-Add-status-trace-for-tps25750.patch to patch 9 - Remove status trace prototype from device data v9: - PATCH 1: - Add Reviewed-by - PATCH 2..7: - No changes - PATCH 8: - Move of_device_id to its original place - Move device data structs to the top of of_device_id - Use device_get_match_data to get device data - PATCH 9: - No changes - PATCH 10: - Move device data structs to the top of of_device_id - PATCH 11,12: - No changes - PATCH 13,14: - Move device data structs to the top of of_device_id v8: - PATCH 1: - Define reg-names at top-level - PATCH 2: - Add Reviewed-by - PATCH 3: - Revert mode check return - PATCH 4: - Return mode when mode is checked - Use device_is_compatible instead of of_device_is_compatible - PATCH 5,6: - No changes - PATCH 7: - Use device_is_compatible instead of of_device_is_compatible - PATCH 8,9: - No changes - PATCH 10: - Change tps->cb to tps->data - PATCH 11,12: - No changes - PATCH 13,14: - Change tps->cb to tps->data v7: - PATCH 1: - Define reg at top-level - Remove description from reg-names - PATCH 2..7: Add tps6598x to the subject - PATCH 8: - Add tps6598x to the subject - Create tps25750 interrupt handler - PATCH 9..11: Add tps6598x to the subject - PATCH 12: - Add driver name to commit subject - Call trace_tps25750_irq directly from tps25750 interrupt handler - PATCH 13-14: Add tps6598x to the subject v6: - PATCH 1: Use reg property for patch address - PATCH 2: Use tps6598x_exec_cmd as a wrapper - PATCH 3: Return current mode and check it directly - PATCH 4: - Don't check VID for tps25750 as the VID register doesn't exist - Remove is_tps25750 flag from tps6598x struct - Get patch address from reg property - PATCH 5: Update eeprom macro to use TPS instead - PATCH 6: No changes - PATCH 7: Check tps25750 using is_compatiable device node - PATCH 8: Create tipd callbacks factory - PATCH 9: No changes - PATCH 10: Add port registration to tipd data factory - PATCH 11: Use tps25750_init instead of tps25750_apply_patch in resume as it initializes sleep mode - PATCH 12: Add trace irq to tipd callbacks factory - PATCH 13: Add trace power status to tipd data factory - PATCH 14: Add trace status to tipd data factory v5: - PATCH 1: Add tps25750 bindings to tps6598x - PATCH 2: Remove tps25750 driver and incorperate tps25750 into tps6598x driver - PATCH [3..15]: Incorporating tps25750 into tps6598x driver v4: - PATCH 1: No change - PATCH 2: Fix comments style and drop of_match_ptr v3: - PATCH 1: Fix node name - PATCH 2: Upload tps25750 driver patch v2: - PATCH 1: General properties clean up Abdel Alkuor (9): dt-bindings: usb: tps6598x: Add tps25750 USB: typec: tsp6598x: Add cmd timeout and response delay USB: typec: tps6598x: Add patch mode to tps6598x USB: typec: tps6598x: Refactor tps6598x port registration USB: typec: tps6598x: Add device data to of_device_id USB: typec: tps6598x: Add TPS25750 support USB: typec: tps6598x: Add trace for tps25750 irq USB: typec: tps6598x: Add power status trace for tps25750 USB: typec: tps6598x: Add status trace for tps25750 .../devicetree/bindings/usb/ti,tps6598x.yaml | 81 ++- drivers/usb/typec/tipd/core.c | 626 ++++++++++++++++-- drivers/usb/typec/tipd/tps6598x.h | 36 + drivers/usb/typec/tipd/trace.h | 92 +++ 4 files changed, 764 insertions(+), 71 deletions(-)
