Dan Carpenter	20f291b88e	iio: adc: imx93: fix a signedness bug in imx93_adc_read_raw() ... The problem is these lines: ret = vref_uv = regulator_get_voltage(adc->vref); if (ret < 0) The "ret" variable is type long and "vref_uv" is u32 so that means the condition can never be true on a 64bit system. A negative error code from regulator_get_voltage() would be cast to a high positive u32 value and then remain a high positive value when cast to a long. The "ret" variable only ever stores ints so it should be declared as an int. We can delete the "vref_uv" variable and use "ret" directly.

Haibo Chen	7d02296ac8	iio: adc: add imx93 adc support ... The ADC in i.mx93 is a total new ADC IP, add a driver to support this ADC. Currently, only support one shot normal conversion triggered by software. For other mode, will add in future.
