00de283c53c99690807f5c875f8c715679a560ef - Merge patch series "auxdisplay: linedisp: support attribute attachment to auxdisplay devices"

Wed, 15 Oct 2025 18:46:08 +0200

Merge patch series "auxdisplay: linedisp: support attribute attachment to auxdisplay devices"Jean-François Lessard says:This series modernizes the auxdisplay line display (linedisp) library toenable seamless integration with auxdisplay parent devices whilemaintaining backward compatibility.The key improvement is adding attach/detach APIs that allow linedisp sysfsattributes to be bound directly to their parent auxdisplay devices avoidingchild device proliferation and enabling a uniform 7-segment userspaceinterface across different driver architectures.This series introduces attachment infrastructure for linedisp devices.The first consumer of this API will be the TM16XX driver series.See the related patch series: auxdisplay: Add TM16xx 7-segment LED matrix display controllers driverChanges include:1. Encapsulate container_of() usage with to_linedisp() helper function for cleaner context retrieval2. Improve message display behavior with static padding when message length is smaller than display width3. Add 'num_chars' read-only attribute for userspace capability discovery4. Add attach/detach API for sysfs attributes binding to parent devices5. Document all linedisp sysfs attributes in ABI documentationAll existing linedisp_register() users remain unaffected. The new APIsenable drivers like TM16XX to integrate 7-segment functionality withintheir LED class device hierarchy while providing a uniform 7-segment API.Thanks to Andy Shevchenko for early feedback and guidance.Link: https://lore.kernel.org/r/20250918121321.116248-1-jefflessard3@gmail.comSigned-off-by: Andy Shevchenko List of files: /linux/Documentation/ABI/testing/sysfs-auxdisplay-linedisp

Thu, 18 Sep 2025 14:13:14 +0200

auxdisplay: linedisp: add num_chars sysfs attributeAdd a read-only 'num_chars' sysfs attribute to report display digit count.The num_chars attribute provides essential capability information touserspace applications that need to know display dimensions before writingmessages, complementing the existing message and scroll controls.No functional changes to existing behavior.Signed-off-by: Jean-François Lessard Signed-off-by: Andy Shevchenko List of files: /linux/Documentation/ABI/testing/sysfs-auxdisplay-linedisp

Thu, 18 Sep 2025 14:13:11 +0200

docs: ABI: auxdisplay: document linedisp library sysfs attributesAdd ABI documentation for sysfs attributes provided by the line-displayauxdisplay library module. These attributes enable text message display andconfiguration on character-based auxdisplay devices.Documents previously undocumented attributes:- message, scroll_step_ms (introduced in v5.16)- map_seg7, map_seg14 (introduced in v6.9)The line-display library is used by multiple auxdisplay drivers andcan expose these attributes either on linedisp.N child devices ordirectly on parent auxdisplay devices.Signed-off-by: Jean-François Lessard Signed-off-by: Andy Shevchenko List of files: /linux/Documentation/ABI/testing/sysfs-auxdisplay-linedisp
