Merge remote-tracking branch 'remotes/cminyard/tags/for-qemu-6.1-2' into staging
Some qemu updates for IPMI and I2C Move some ADC file to where they belong and move some sensors to a sensor directory, since with new BMCs coming in lots of different sensors should be coming in. Keep from cluttering things up. Add support for I2C PMBus devices. Replace the confusing and error-prone i2c_send_recv and i2c_transfer with specific send and receive functions. Several errors have already been made with these, avoid any new errors. Fix the watchdog_expired field in the IPMI watchdog, it's not a bool, it's a u8. After a vmstate transfer, the new value could be wrong. # gpg: Signature made Fri 09 Jul 2021 17:25:04 BST # gpg: using RSA key FD0D5CE67CE0F59A6688268661F38C90919BFF81 # gpg: Good signature from "Corey Minyard <cminyard@mvista.com>" [unknown] # gpg: aka "Corey Minyard <minyard@acm.org>" [unknown] # gpg: aka "Corey Minyard <corey@minyard.net>" [unknown] # gpg: aka "Corey Minyard <minyard@mvista.com>" [unknown] # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: FD0D 5CE6 7CE0 F59A 6688 2686 61F3 8C90 919B FF81 * remotes/cminyard/tags/for-qemu-6.1-2: (24 commits) tests/qtest: add tests for MAX34451 device model hw/misc: add MAX34451 device tests/qtest: add tests for ADM1272 device model hw/misc: add ADM1272 device hw/i2c: add support for PMBus ipmi/sim: fix watchdog_expired data type error in IPMIBmcSim struct hw/i2c: Introduce i2c_start_recv() and i2c_start_send() hw/i2c: Extract i2c_do_start_transfer() from i2c_start_transfer() hw/i2c: Make i2c_start_transfer() direction argument a boolean hw/i2c: Rename i2c_set_slave_address() -> i2c_slave_set_address() hw/i2c: Remove confusing i2c_send_recv() hw/misc/auxbus: Replace i2c_send_recv() by i2c_recv() & i2c_send() hw/misc/auxbus: Replace 'is_write' boolean by its value hw/misc/auxbus: Explode READ_I2C / WRITE_I2C_MOT cases hw/misc/auxbus: Fix MOT/classic I2C mode hw/i2c/ppc4xx_i2c: Replace i2c_send_recv() by i2c_recv() & i2c_send() hw/i2c/ppc4xx_i2c: Add reference to datasheet hw/display/sm501: Replace i2c_send_recv() by i2c_recv() & i2c_send() hw/display/sm501: Simplify sm501_i2c_write() logic hw/input/lm832x: Define TYPE_LM8323 in public header ...
