^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) Every ST-Ericsson Ux500 SOC consists of both ABx500 and DBx500 physically,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) this is kernel hwmon driver for ABx500.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) There are some GPADCs inside ABx500 which are designed for connecting to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) thermal sensors, and there is also a thermal sensor inside ABx500 too, which
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) raises interrupt when critical temperature reached.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) This abx500 is a common layer which can monitor all of the sensors, every
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) specific abx500 chip has its special configurations in its own file, e.g. some
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) sensors can be configured invisible if they are not available on that chip, and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) the corresponding gpadc_addr should be set to 0, thus this sensor won't be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) polled.
