The purpose of Ventura is to detect liquid leakage from all compute trays, switch trays and rack sensors within the rack, log the events, and take necessary actions accordingly. --- v1: 1. Create ventura dts file. 2. Add commit msg. 3. Use format-patch to generate patch. 4. Add subject prefixes matching the subsystem. --- v2: 1. Modify email content. --- v3: 1. Add mail list. --- v4: 1. Apply git send-email --thread option. 2. Sort nodes in the dts alphanumerically. --- v5: 1. Run scripts/checkpatch.pl and fix reported warnings. 2. Remove unnecessary 88E6393X CONFIG FRU. --- v6: 1. Add a new stage for the DTS change. 2. Run scripts/checkpatch.pl and fix reported error. 3. Fix the issue in a separate patch. --- v7: 1. Fix broken indentation in the device tree file. 2. Sort nodes alphabetically, then by address if equal. 3. Rename fan sensor nodes from 'hwmon' to 'fan-controller'. --- v8: 1. This patch series has significant changes compared to previous versions, and quite some time has passed since the last submission.Therefore, previously received Acked-by/Reviewed-by/Tested-by tags are not included in this version. If needed, tags can be added again after review of thisnew version. --- v9: 1. Reordered the node sequence under i2c5. 2. Added a description of the platform's intended use to the commit messages. 3. Added 3 GPIO expanders to i2c10 and defined the necessary GPIO line names. --- v10: 1. Added IRQ support in GPIO expanders under i2c10 to handle edge-triggered events. 2. Reordered the nodes. --- v11: 1. Modified the position for i2c3mux0ch6 and i2c3mux0ch7. --- v12: 1. Added a GPIO expander at address 0x11 on i2c10, and assign an SGPIO pin as the IRQ for it. 2. Fixed the "failed to match any schema with compatible" issues. 3. Reorder the nodes in alphabetically. --- v13: 1. Add two GPIO expanders (0x16 and 0x17) to i2c10 and assign two SGPIO pins as IRQs. 2. Move the RPU_READY_SPARE_PLD_R and RPU_2_READY_PLD_R pins from SGPIO to the GPIO expander (0x10). 3. Add all tray PWREN pins to the GPIO expanders (0x16, 0x17 and 0x1b). 4. Add explanatory comments for "unmanaged mode" under &mac3 and "intentionally left empty" under &mdio. --- v14: 1. Modify "Facebook ventura RMC" to "Facebook Ventura RMC" 2. Add a description for each bus alias. 3. Revise commenting style. 4. Enable mac0 5. Remove two GPIO expanders (0x16 and 0x17) to i2c10 and two SGPIO pins as IRQs. 6. Move the RPU_READY_SPARE_PLD_R and RPU_2_READY_PLD_R pins from the GPIO expander (0x10) to SGPIO.
