video: backlight: lm3533_bl: Implement backlight_scale property

2026-09-10T14:02:16+00:00

Since the device supports linear and non-linear modes, implement the backlight_scale property to describe this state. Signed-off-by: Svyatoslav Ryhel Reviewed-by: Daniel Thompson (RISCstar) Link: https://patch.msgid.link/20260731113632.158440-14-clamor95@gmail.com Signed-off-by: Lee Jones

mfd: lm3533: Convert to use OF bindings

2026-09-10T14:00:41+00:00

Since there are no users of this driver via platform data, remove the platform data support and switch to using Device Tree bindings. Previously, all cell devices were linked to the parent device. This could cause problems further down the line because the LM3533 has multiple cells of the same type. Using a single phandle to the parent could cause confusion when attempting to reference or call the correct child node. Since this commit adds a dedicated node for every cell, remove linking of the cell to the parent node.

mfd: lm3533: Use dev_groups in struct device_driver

2026-09-10T14:00:33+00:00

Instead of creating and removing the device sysfs attributes directly during probe and remove of the driver, respectively, use dev_groups in struct device_driver to point to the attribute definitions and let the core take care of creating and removing them. No intentional functional impact.

Replace sprintf() with sysfs_emit() in the sysfs show callbacks of backlight.c and lcd.c, as recommended by Documentation/filesystems/sysfs.rst. No functional change intended.
