dt-bindings: nfc: ti,trf7970a: Restrict the ti,rx-gain-reduction-db values

2025-08-28T00:17:58Z

Instead of stating the supported values for the ti,rx-gain-reduction-db property in free text format, add an enum entry that can help validating the devicetree files.

dt-bindings: nfc: ti,trf7970a: Drop 'db' suffix duplicating dtschema

A common property unit suffix '-db' was added to dtschema, thus in-kernel bindings should not reference the type. Signed-off-by: Krzysztof Kozlowski Acked-by: Conor Dooley Link: https://patch.msgid.link/20250811142235.170407-2-krzysztof.kozlowski@linaro.org Signed-off-by: Jakub Kicinski

dt-bindings: Fix SPI and I2C bus node names in examples

2023-03-08T15:04:53Z

SPI and I2C bus node names are expected to be "spi" or "i2c", respectively, with nothing else, a unit-address, or a '-N' index. A pattern of 'spi0' or 'i2c0' or similar has crept in. Fix all these cases. Mostly scripted with the following commands: git grep -l '\si2c[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/i2c[0-9] {/i2c {/' git grep -l '\sspi[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/spi[0-9] {/spi {/' With this, a few errors in examples were exposed and fixed.
