2025-11-21drm/bridge: sii902x: Fix HDMI detection with DRM_BRIDGE_ATTACH_NO_CONNECTORDevarsh Thakkar
The sii902x driver was caching HDMI detection state in a sink_is_hdmi field and checking it in mode_set() to determine whether to set HDMI or DVI output mode. This approach had two problems: 1. With DRM_BRIDGE_ATTACH_NO_CONNECTOR (used by modern display drivers like TIDSS), the bridge's get_modes() is never called. Instead, the drm_bridge_connector helper calls the bridge's edid_read() and updates the connector itself. This meant sink_is_hdmi was never populated, causing the driver to default to DVI mode and breaking HDMI audio. 2. The mode_set() callback doesn't receive atomic state or connector pointer, making it impossible to check connector->display_info.is_hdmi directly at that point. Fix this by moving the HDMI vs DVI decision from mode_set() to atomic_enable(), where we can access the connector via drm_atomic_get_new_connector_for_encoder(). This works for both connector models: - With DRM_BRIDGE_ATTACH_NO_CONNECTOR: Returns the drm_bridge_connector created by the display driver, which has already been updated by the helper's call to drm_edid_connector_update() - Without DRM_BRIDGE_ATTACH_NO_CONNECTOR (legacy): Returns the connector embedded in sii902x struct, which gets updated by the bridge's own get_modes() Fixes: 3de47e1309c2 ("drm/bridge: sii902x: use display info is_hdmi") Signed-off-by: Devarsh Thakkar <devarsht@ti.com> Reviewed-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> Signed-off-by: Neil Armstrong <neil.armstrong@linaro.org> Link: https://patch.msgid.link/20251030151635.3019864-1-devarsht@ti.com
2025-11-21drm/bridge: it66121: Add minimal it66122 supportNishanth Menon
The IT66122 is a pin compatible replacement for the IT66122. Based on empirical testing, the new device looks to be compatible with IT66121. However due to a lack of public data sheet at this time beyond overall feature list[1] (which seems to add additional features vs ITT66121), it is hard to determine that additional register operations required to enable additional features. So, introduce the device as a new compatible that we will detect based on vid/pid match, with explicit id that can be used to extend the driver capability as information becomes available later on.

2025-11-21drm/bridge: it66121: Use vid/pid to detect the type of chipNishanth Menon
The driver knows exactly which version of the chip is present since the vid/pid is used to enforce a compatibility. Given that some devices like IT66121 has potentially been replaced with IT66122 mid production for many platforms, it makes no sense to use the vid/pid as an enforcement for compatibility. Instead, detect the ID of the actual chip in use by matching the corresponding vid/pid and drop the compatible specific lookup table.

Members of struct software_node_ref_args should not be dereferenced directly but set using the provided macros. Commit d7cdbbc93c56 ("software node: allow referencing firmware nodes") changed the name of the software node member and caused a build failure. Remove all direct dereferences of the ref struct as a fix. However, this driver also seems to abuse the software node interface by waiting for a node with an arbitrary name "intel-xhci-usb-sw" to appear in the system before setting up the reference for the I2C device, while the actual software node already exists in the intel-xhci-usb-role-switch module and should be used to set up a static reference.

The .return_sites and .call_sites sections reference text addresses, but not with the intent to indirect branch to them, so they don't need to be validated for IBT. This is useful when running objtool on object files which already have .return_sites or .call_sites sections, for example to re-run objtool after it has reported an error or a warning.

Use with FIELD_GET() and FIELD_PREP() to allow dropping of shift defines. - Use macros to define event related fields. - Switch to an address lookup based on an index variable to replace lots of very similar register macros. - Rename activity_event_en() to generic_event_en() to better reflect what it does. - Improve comments around interrupt register handling. fsl,mpl3115 - Factor out code for triggered buffer data collection. - Use more consistent register field naming style. - Use get_unaligned_be24() to get the pressure. invensense,mpu6050 - Drop false requirement in DT binding for the interrupt. The driver will be able to do less if one is not provided, but some features are still available. invensense,icm45600_i3c - Fix missing return on failure to match part. linear,ltc2688 - Use devm_mutex_init() so mutex_destroy() is called in tear down path. - Use guard() to simplify lock handling in error return paths. qcom,vadc - Fix up some kernel-doc related warnings. rohm,bd79112 and bd79124 - Use regmap_reg_range() helper to set the ranges. st,lsm6dsx - Fix units of ODR in structure documentation. ti,am335x - Add range checks to avoid a compiler warning. ti,pac1934 - Switch to system_percpu_wq.

2025-11-21spi: spi-fsl-lpspi: fix watermark truncation caused by type castCarlos Song
't->len' is an unsigned integer, while 'watermark' and 'txfifosize' are u8. Using min_t with typeof(watermark) forces both values to be cast to u8, which truncates len when it exceeds 255. For example, len = 4096 becomes 0 after casting, resulting in an incorrect watermark value. Use a wider type in min_t to avoid truncation and ensure the correct minimum value is applied.
