2020-03-08hwmon: (pmbus) Implement multi-phase supportGuenter Roeck
Some PMBus chips support multiple phases, and report telemetry such as input current, output current, or temperature for each phase. Add support for such chips to the PMBus core. Start with a maximum of 8 phases per page, and assume that supported sensors per phase are similar for all pages. Only support per-phase telemetry attributes, no limits or alarms. As part of this patch, set the initial page variable to 0xff to ensure that the page is updated when the first page command is issued. Also only issue page commands if the chip supports more than one page. Cc: Vadim Pasternak <vadimp@mellanox.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
