Update Kiran's email address to match the .mailmap entry. This will help anyone that is looking to reach out about this binding and is not using .mailmap to pre-process their message.

2023-11-23dt-bindings: backlight: mp3309c: Remove two required propertiesFlavio Suligoi1-6/+4
The two properties: - max-brightness - default brightness are not really required, so they can be removed from the "required" section. The "max-brightness" is no longer used in the current version of the driver (it was used only in the first version). The "default-brightness", if omitted in the DT, is managed by the device driver, using a default value. This value depends on the dimming mode used: - for the "analog mode", via I2C commands, this value is fixed by hardware (=31) - while in case of pwm mode the default used is the last value of the brightness-levels array. Also the brightness-levels array is not required: - in "analog mode", via I2C commands, the brightness-level array is fixed by hardware (0..31).; - in pwm dimming mode, the driver uses a default array of 0..255 and the "default-brightness" is the last one, which is "255" NOTE: there are no compatibility problems with the previous version, since the device driver has not yet been included in any kernel. Only this dt-binding yaml file is already included in the current v6.7.0-rc1 kernel version. No developer may have used it. Other changes: - improve the backlight working mode description, in the "description" section - update the example, removing the "max-brightness" and introducing the "brightess-levels" property Signed-off-by: Flavio Suligoi <[email protected]> Acked-by: Conor Dooley <[email protected]> Reviewed-by: Daniel Thompson <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Lee Jones <[email protected]>

Notable changes: - ROM child nodes use dashes instead of underscores; the driver reads all child nodes regardless of their names, so this doesn't break ABI. - pwm-period argument is deprecated, as it effectively duplicates the period value provided in pwms.

In addition, as of commit deaeeda2051fa280 ("backlight: pwm_bl: Don't rely on a disabled PWM emiting inactive state"), the Linux driver considers the power supply optional.

The 'phandle-array' type is a bit ambiguous. It can be either just an array of phandles or an array of phandles plus args. Many schemas for phandle-array properties aren't clear in the schema which case applies though the description usually describes it.

2020-08-14dt-bindings: Whitespace clean-ups in schema filesRob Herring1-1/+2
Clean-up incorrect indentation, extra spaces, long lines, and missing EOF newline in schema files. Most of the clean-ups are for list indentation which should always be 2 spaces more than the preceding keyword. Found with yamllint (which I plan to integrate into the checks).

2020-07-13dt-bindings: backlight: Convert common backlight bindings to DT schemaRob Herring6-105/+202
Convert the common GPIO, LED, and PWM backlight bindings to DT schema format. Given there's only 2 common properties and the descriptions are slightly different, I opted to not create a common backlight schema.

2020-06-11dt-bindings: Remove more cases of 'allOf' containing a '$ref'Rob Herring1-26/+17
Another round of 'allOf' removals that came in this cycle. json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Signed-off-by: Rob Herring <[email protected]>
