From daec55ce62ad0bb6948c8edf84e7ec3b95720177 Mon Sep 17 00:00:00 2001 From: Felix Nieuwenhuizen Date: Thu, 27 Oct 2022 16:51:35 +0200 Subject: hwmon: (pmbus/ltc2978) add support for LTC7132 Add support for LTC7132. The relevant registers in the LTC7132 are identical to the LTC7880. So it's just a matter of adding the chip id.
