Pull i2c updates from Wolfram Sang: "This removes the currently unused CLASS_DDC support (controllers set the flag, but there is no client to use it). Also, CLASS_SPD support gets simplified to prepare removal in the future. Class based instantiation is not recommended these days anyhow. Furthermore, I2C core now creates a debugfs directory per I2C adapter. Current bus driver users were converted to use it. Finally, quite some driver updates. Standing out are patches for the wmt-driver which is refactored to support more variants. This is the rebased pull request where a large series for the designware driver was dropped" * tag 'i2c-for-6.8-rc1-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (38 commits) MAINTAINERS: use proper email for my I2C work i2c: stm32f7: add support for stm32mp25 soc i2c: stm32f7: perform I2C_ISR read once at beginning of event isr dt-bindings: i2c: document st,stm32mp25-i2c compatible i2c: stm32f7: simplify status messages in case of errors i2c: stm32f7: perform most of irq job in threaded handler i2c: stm32f7: use dev_err_probe upon calls of devm_request_irq i2c: i801: Add lis3lv02d for Dell XPS 15 7590 i2c: i801: Add lis3lv02d for Dell Precision 3540 i2c: wmt: Reduce redundant: REG_CR setting i2c: wmt: Reduce redundant: function parameter i2c: wmt: Reduce redundant: clock mode setting i2c: wmt: Reduce redundant: wait event complete i2c: wmt: Reduce redundant: bus busy check i2c: mux: reg: Remove class-based device auto-detection support i2c: make i2c_bus_type const dt-bindings: at24: add ROHM BR24G04 eeprom: at24: use of_match_ptr() i2c: cpm: Remove linux,i2c-index conversion from be32 i2c: imx: Make SDA actually optional for bus recovering ...

drm: remove I2C_CLASS_DDC support

2024-01-18T20:10:41Z

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.

Pull drm updates from Dave Airlie: "This contains two major new drivers: - imagination is a first driver for Imagination Technologies devices, it only covers very specific devices, but there is hope to grow it - xe is a reboot of the i915 GPU (shares display) side using a more upstream focused development model, and trying to maximise code sharing. It's not enabled for any hw by default, and will hopefully get switched on for Intel's Lunarlake. This also drops a bunch of the old UMS ioctls. It's been dead long enough. amdgpu has a bunch of new color management code that is being used in the Steam Deck. amdgpu also has a new ACPI WBRF interaction to help avoid radio interference. Otherwise it's the usual lots of changes in lots of places.

drm/mediatek: dp: Add phy_mtk_dp module as pre-dependency

2023-12-18T14:31:32Z

The mtk_dp driver registers a phy device which is handled by the phy_mtk_dp driver and assumes that the phy probe will complete synchronously, proceeding to make use of functionality exposed by that driver right away. This assumption however is false when the phy driver is built as a module, causing the mtk_dp driver to fail probe in this case. Add the phy_mtk_dp module as a pre-dependency to the mtk_dp module to ensure the phy module has been loaded before the dp, so that the phy probe happens synchrounously and the mtk_dp driver can probe successfully even with the phy driver built as a module.

Padding is a new display module on MT8188, it provides ability to add pixels to width and height of a layer with specified colors. Due to hardware design, Mixer in VDOSYS1 requires width of a layer to be 2-pixel-align, or 4-pixel-align when ETHDR is enabled, we need Padding to deal with odd width.
