2024-01-19drm/amd/display: Drop 'acrtc' and add 'new_crtc_state' NULL check for ↵Srinivasan Shanmugam1-3/+3

2024-01-19drm/amdgpu: revert "Adjust removal control flow for smu v13_0_2"Christian König4-65/+1
Calling amdgpu_device_ip_resume_phase1() during shutdown leaves the HW in an active state and is an unbalanced use of the IP callbacks. Using the IP callbacks like this can lead to memory leaks, double free and imbalanced reference counters. Leaving the HW in an active state can lead to DMA accesses to memory now freed by the driver. Both is a complete no-go for driver unload so completely revert the workaround for now. This reverts commit f5c7e7797060255dbc8160734ccc5ad6183c5e04.

2024-01-18i2c: stm32f7: add support for stm32mp25 socAlain Volmat1-88/+126
The stm32mp25 has only a single interrupt line used for both events and errors. In order to cope with that, reorganise the error handling code so that it can be called either from the common handler (used in case of SoC having only a single IT line) and the error handler for others. The CR1 register also embeds a new FMP bit, necessary when running at Fast Mode Plus frequency. This bit should be used instead of the SYSCFG bit used on other platforms. Add a new compatible to distinguish between the SoCs and two boolean within the setup structure in order to know if the platform has a single/multiple IT lines and if the FMP bit within CR1 is available or not.

2024-01-18drm/amd/pm: Remove I2C_CLASS_SPD supportHeiner Kallweit3-3/+0
I2C_CLASS_SPD was used to expose the EEPROM content to user space, via the legacy eeprom driver. Now that this driver has been removed, we can remove I2C_CLASS_SPD support. at24 driver with explicit instantiation should be used instead.

After removal of the legacy EEPROM driver and I2C_CLASS_DDC support in olpc_dcon there's no i2c client driver left supporting I2C_CLASS_DDC. Class-based device auto-detection is a legacy mechanism and shouldn't be used in new code. So we can remove this class completely now.

2024-01-18i40e: Include types.h to some headersTony Nguyen2-0/+2
Commit 56df345917c0 ("i40e: Remove circular header dependencies and fix headers") redistributed a number of includes from one large header file to the locations they were needed. In some environments, types.h is not included and causing compile issues. The driver should not rely on implicit inclusion from other locations; explicitly include it to these files. Snippet of issue. Entire log can be seen through the Closes: link.
