Update the example to match reality. Signed-off-by: Biju Das Reviewed-by: Krzysztof Kozlowski --- v6->v7: * No change. v5->v6: * No change v4_new->v5: * No change. v4->v4_new: * Moved this patch to PMIC series * Added minItems to interrupt-names. * Added interrupt-names in conditional schema check. v3->v4: * Added Rb tag from Krzysztof Kozlowski. * Dropped | from description * Replaced the pin name #EVDET->EVDET in description. * Dropped oneOf from compatible. v2->v3: * Updated interrupt-names property by keeping the list of names. * Removed Interrupts from required property as it may not be wired. * Removed isil,ev-evienb from required property. RFC->v2: * Updated maintainers list * Updated description from original bindings * removed default from isil,ev-evienb properties to match with the original bindings. * Added conditional check for interrupts. --- .../devicetree/bindings/rtc/isil,isl1208.txt | 38 -------- .../devicetree/bindings/rtc/isil,isl1208.yaml | 89 +++++++++++++++++++ 2 files changed, 89 insertions(+), 38 deletions(-) delete mode 100644 Documentation/devicetree/bindings/rtc/isil,isl1208.txt create mode 100644 Documentation/devicetree/bindings/rtc/isil,isl1208.yaml diff --git a/Documentation/devicetree/bindings/rtc/isil,isl1208.txt b/Documentation/devicetree/bindings/rtc/isil,isl1208.txt deleted file mode 100644 index 51f003006f04..000000000000 --- a/Documentation/devicetree/bindings/rtc/isil,isl1208.txt +++ /dev/null @@ -1,38 +0,0 @@ -Intersil ISL1209/19 I2C RTC/Alarm chip with event in - -ISL12X9 have additional pins EVIN and #EVDET for tamper detection, while the -ISL1208 and ISL1218 do not.
