Add the binding description and the corresponding driver for the Kinetic KTD2026 and KTD2027. Signed-off-by: André Apitzsch <git@xxxxxxxxxxx> --- Changes in v6: - Remove un-needed inits - Narrow scope of variables - Release of_node references on early exit - Pass child node to dev_err() in ktd202x_setup_led_rgb() - Link to v5: https://lore.kernel.org/r/20231001-ktd202x-v5-0-f544a1d0510d@xxxxxxxxxxx Changes in v5: - Restructure brightness_set() + add comments to it to be easier understandable - Add some line breaks + remove little line-wraps to improve readability - Move parts of add_led() to setup_led_{rgb,single}() - Move mutex_init() to the end of probe to omit gotos - Fix grammar - Set initial intensity to max brightness to avoid LED staying off when brightness is changed after switching to timer trigger, because of zero intensity - Link to v4: https://lore.kernel.org/r/20230923-ktd202x-v4-0-14f724f6d43b@xxxxxxxxxxx Changes in v4: - Annotate struct ktd202x with __counted_by - Link to v3: https://lore.kernel.org/r/20230906-ktd202x-v3-0-7fcb91c65d3a@xxxxxxxxxxx Changes in v3: - Add r-b to bindings patch - Replace .probe_new by .probe - Link to v2: https://lore.kernel.org/r/20230901-ktd202x-v2-0-3cb8b0ca02ed@xxxxxxxxxxx Changes in v2: - Make binding description filename match compatible - Address comments by Lee Jones - Extend driver description in Kconfig - Add copyright + link to datasheet - Add unit to definition/variable names, where needed - Define magic numbers - Remove forward declaration of 'struct ktd202x' - Remove superfluous comments - Get rid of struct ktd202x_info - Join ktd202x_chip_init() with ktd202x_chip_enable() - Return the error on ktd202x_chip_disable() - Remove unreachable case from chip_in_use() - Rename ktd202x_brightness_set() argument from num_colors to num_channels - Forward errors received in ktd202x_brightness_set() - Remove variable for 'num_channels = 1' - Add some explanations to blink time calculation - Remove unneeded lcdev from ktd202x_blink_*_set() - Add define for max brightness and replace deprecated LED_FULL by it - Move setting led_classdev.brightness to ktd202x_brightness_*_set() - Move mutex_lock inside ktd202x_blink_set() - Add comment that 'color' property is optional (allow EINVAL) - Replace escaped double quotes by single quotes - Avoid overloading variable 'color' - Do not lock during probe - Remove usage of 'of_match_ptr' - Document interrupt and pull-up supply, like done for aw2013[1] - Fix error in num_steps calculation - Link to v1: https://lore.kernel.org/r/20230618-ktd202x-v1-0-fc182fefadd7@xxxxxxxxxxx [1] https://lore.kernel.org/linux-leds/20230815-aw2013-vio-v3-0-2505296b0856@xxxxxxxxxxx/ --- André Apitzsch (2): dt-bindings: leds: Add Kinetic KTD2026/2027 LED leds: add ktd202x driver .../devicetree/bindings/leds/kinetic,ktd202x.yaml | 171 ++++++ drivers/leds/rgb/Kconfig | 13 + drivers/leds/rgb/Makefile | 1 + drivers/leds/rgb/leds-ktd202x.c | 625 +++++++++++++++++++++ 4 files changed, 810 insertions(+) --- base-commit: 165adeea3617ea22dc49f8880474ebf3a98b696d change-id: 20230618-ktd202x-546b2a7d240b Best regards, -- André Apitzsch <git@xxxxxxxxxxx>
