2021-11-04superio: Replace bad uses of `find_resource`Angel Pons
The `find_resource` function will never return null (will die instead). In cases where the existing code already accounts for null pointers, it is better to use `probe_resource` instead, which returns a null pointer instead of dying.

2020-09-22superio/ite: Distinguish between chips for PECI readingsMichael Büchler
Some chips can read external temperature sensor values only to TMPIN3. These use EC register 0x55, bit 7 to enable that. This patch adds support for this. It is called "old PECI" by lm_sensors [0]. Other chips can read to any TMPIN[1-3] which is configured in EC register 0x51 like the other temperature sources. This was the only supported method. This patch adds a Kconfig option to indicate this variant. This patch was tested on an Acer Aspire M3800 which has an IT8720F that reads the CPU temperature via PECI. It allows the automatic fan control feature of the Super I/O to work. Overview of support per chip in the coreboot tree, determined from reading the publicly available datasheets or lm_sensors, if noted: Old PECI: * IT8718F * IT8720F * IT8781F, IT8782F, IT8783E/F Normal PECI: * IT8721F (exception: no PECI to TMPIN2) * IT8728F * IT8772E (uses separate code in coreboot, not superio/ite/common) * IT8786E * IT8613E, IT8623E (lm_sensors) [0] Linux kernel 5.4.48, drivers/hwmon/it87.c Signed-off-by: Michael Büchler <michael.buechler@posteo.net> Change-Id: Iab7115852437d46c9b1269bba61ffcf680fe5a6a Reviewed-on: https://review.coreboot.org/c/coreboot/+/44168 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Angel Pons <th3fanbus@gmail.com>
