<20260731113632.158440-1-clamor95@gmail.com> X-Mailer: git-send-email 2.53.0 Precedence: bulk X-Mailing-List: linux-kernel@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Content-Transfer-Encoding: 8bit Convert LM3533 to OF bindings, add missing VIN supply, add support for setting mapping mode and LED sources based on device tree. --- Changes in v2: schema - maximum led sources for leds set to 4 - anyOf > oneOf in ALS - improved ALS descriptions - adjusted example drivers - dropped devm convertion of irq and mfd helpers - all als configuration moved into lm3533_als_setup - added regulator/consumer.h - lm3533_bl_setup set before sysfs_create_group in backlight - added check if LVLED is valid - LM3533_REG_OUTPUT_CONF1 > LM3533_REG_OUTPUT_CONF2 for LVLED4 and LVLED5 Changes in v3: - ohm -> ohms - added default PWM mask to schema - added commit removing driver regmap wrappers - added commits which flatten pdata helpers - adjusted check if als->irq > 0 since als->irq can be negative if error/missing - added count for children defined in device tree and mfd_cell is allocated via devm_kcalloc to be able to contain all of them - fixed backlight boundary check - fixed count increased unconditionally - dev_err returns node name instead of reg value - LM3533_MAX_CURRENT_* defines moved to common header since they are used to clamp current values read from the tree - mapping mode commit splitted into 2 (sysfs logic improvement > mode from DT) - backlight mode configuration set before sysfs group is created - fixed LVLED check on LEDs setup - added check if HVLED is valid - fixed wrong err_sysfs_remove goto in lm3533_bl - added commit implementing backlight_scale property Changes in v4: - fixed regmap_update_bits val and mask swap in lm3533_als_set_int_mode - fixed als->irq check in store_thresh_either_en - removed clamping of r_select in als driver - added use_of_reg and of_reg for backlight and leds registration - added intermediate step in asigning props.brightness - fixed HVLED/LVLED configuration overwriting - added bounds check for num_leds in leds and backlight driver - switched to regmap_clean/set/assign/test_bits helpers where appropriate - dropped extern from header function declartions - switched lm3533 pointer in cell structures to regmap - sysfs_create_group > device_add_group - changes in backlight sysfs were expanded to all properties Changes in v5: - aligned driver helpers to use u32 - child nodes parsing linked with 'else if' to ensure there is one call per node - removed redundant pwm var init for leds - fixed regmap_test_bits return check - fixed leds and backlight counting handling - iterator variables made scoped - lm3533_als_setup() set to exit after mode set if m0de is pwm Changes in v6: - expanded commit message in OF conversion commit - restored original comment regarding PWM mode of ALS - switched to FIELD_PREP macro in core for helper flattening --- Svyatoslav Ryhel (14): dt-bindings: leds: Document TI LM3533 LED controller mfd: lm3533: Remove driver specific regmap wrappers mfd: lm3533: Remove extern from shared functions in the
