charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the old lis302.txt with a YAML binding covering all four compatibles (st,lis3lv02d, st,lis302dl-spi, st,lis331dlh, st,lis33de) and their ~35 DT properties. The old txt documented st,click-thresh-* and st,click-click-time-limit but the code reads st,click-threshold-* and st,click-time-limit. Keep the old names as deprecated so existing DTBs don't break. Tested: dt_binding_check. dtbs_check against 7 omap/am335x DTBs (am335x-evm, am335x-evmsk, am335x-pepper, am437x-sk-evm, omap3-n900, omap3-n950, omap3-gta04a3) — no misc schema errors. Pre-existing IIO schema errors on paired compatible nodes unchanged. Signed-off-by: Jad Keskes --- v4: - Drop explicit select block (redundant — dt-schema generates it from the compatible list automatically) - Fix commit message: select block does not prevent IIO schema validation v3: - Add st,lis3lv02d to select block - Drop Patch 2 entirely, single patch with no IIO changes v2: - Rebase onto Linux 7.1-rc6 - Drop IIO changes .../devicetree/bindings/iio/accel/lis302.txt | 119 ------ .../bindings/misc/st,lis3lv02d.yaml | 400 ++++++++++++++++++ MAINTAINERS | 1 + 3 files changed, 401 insertions(+), 119 deletions(-) delete mode 100644 Documentation/devicetree/bindings/iio/accel/lis302.txt create mode 100644 Documentation/devicetree/bindings/misc/st,lis3lv02d.yaml diff --git a/Documentation/devicetree/bindings/iio/accel/lis302.txt b/Documentation/devicetree/bindings/iio/accel/lis302.txt deleted file mode 100644 index 457539647f36..000000000000 --- a/Documentation/devicetree/bindings/iio/accel/lis302.txt +++ /dev/null @@ -1,119 +0,0 @@ -LIS302 accelerometer devicetree bindings - -This device is matched via its bus drivers, and has a number of properties -that apply in on the generic device (independent from the bus). - - -Required properties for the SPI bindings: - - compatible: should be set to "st,lis3lv02d-spi" - - reg: the chipselect index - - spi-max-frequency: maximal bus speed, should be set to 1000000 unless - constrained by external circuitry - - interrupts: the interrupt generated by the device - -Required properties for the I2C bindings: - - compatible: should be set to "st,lis3lv02d" - - reg: i2c slave address - - Vdd-supply: The input supply for Vdd - - Vdd_IO-supply: The input supply for Vdd_IO - - -Optional properties for all bus drivers: - - - st,click-single-{x,y,z}: if present, tells the device to issue an - interrupt on single click events on the - x/y/z axis. - - st,click-double-{x,y,z}: if present, tells the device to issue an - interrupt on double click events on the - x/y/z axis. - - st,click-thresh-{x,y,z}: set the x/y/z axis threshold - - st,click-click-time-limit: click time limit, from 0 to 127.5msec - with step of 0.5 msec - - st,click-latency: click latency, from 0 to 255 msec with - step of 1 msec. - - st,click-window: click window, from 0 to 255 msec with - step of 1 msec. - - st,irq{1,2}-disable: disable IRQ 1/2 - - st,irq{1,2}-ff-wu-1: raise IRQ 1/2 on FF_WU_1 condition - - st,irq{1,2}-ff-wu-2: raise IRQ 1/2 on FF_WU_2 condition - - st,irq{1,2}-data-ready: raise IRQ 1/2 on data ready condition - - st,irq{1,2}-click: raise IRQ 1/2 on click condition - - st,irq-open-drain: consider IRQ lines open-drain - - st,irq-active-low: make IRQ lines active low - - st,wu-duration-1: duration register for Free-Fall/Wake-Up - interrupt 1 - - st,wu-duration-2: duration register for Free-Fall/Wake-Up - interrupt 2 - - st,wakeup-{x,y,z}-{lo,hi}: set wakeup condition on x/y/z axis for - upper/lower limit - - st,wakeup-threshold: set wakeup threshold - - st,wakeup2-{x,y,z}-{lo,hi}: set wakeup condition on x/y/z axis for - upper/lower limit for second wakeup - engine. - - st,wakeup2-threshold: set wakeup threshold for second wakeup - engine. - - st,highpass-cutoff-hz=: 1, 2, 4 or 8 for 1Hz, 2Hz, 4Hz or 8Hz of - highpass cut-off frequency - - st,hipass{1,2}-disable: disable highpass 1/2. - - st,default-rate=: set the default rate - - st,axis-{x,y,z}=: set the axis to map to the three coordinates. - Negative values can be used for inverted axis. - - st,{min,max}-limit-{x,y,z} set the min/max limits for x/y/z axis - (used by self-test) - - -Example for a SPI device node: - - accelerometer@0 { - compatible = "st,lis302dl-spi";
