What about "microchip,irq-active-high"? Also, patch 3/3, which documents this new property, can be squashed into this one. > + error = regmap_write(priv->regmap, CAP1106_REG_CONFIG2, 0); This register controls a lot more details than that. Overriding it with 0 doesn't seem right. Please use regmap_update_bits() to just update ALT_POL, and also add a #define for it, so the next reader knows what the code is doing :) Thanks, Daniel
