Subject: regmap: add helper macro to set min/max range of register
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6112fe60ac1bd1e68da8cc4248289d6e48015f9b;p=linux-beck.git

regmap: add helper macro to set min/max range of register

Add helper macro to set the min and max value of the register range.

This is useful when initialising the register ranges of the device like

static const struct regmap_range readable_ranges[] = {
	regmap_reg_range(DEVICE_REG0, DEVICE_REG10),
};
