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)

According to the IT8728F datasheet it is possible to add an extra delay
between 3VSBSW# being set and PWRGD3 being set during resume from
Suspend-to-RAM. This is enabled in the special function selection
register, the default being 0.
This is also useful for the IT8720F although this chip does not have the
PWRGD3 output. On the corresponding pin it has PWROK2, which the setting
then seems to apply to.
The datasheet for the IT8720F marks the corresponding bit as reserved,
but the vendor BIOS of an Acer Aspire M3800 sets it anyway. Without
setting the bit, coreboot fails to resume from S3. Oscilloscope
measurements have shown that setting the bit increases the delay between
3VSBSW# being set and PWROK2 being set from around 1 us to 140 ms. The
actual use of PWROK2 on the board design is unclear - the only
destination it seems to reach is a pin header near the SuperIO marked as
"GPIO1".

The interface selection register of the environment controller (EC)

Previously the chip was always configured for the 32 MHz clock. Add an
option that can be set from devicetree.cb to allow using the 24 MHz
clock.
Without this setting the automatic fan control on an Acer Aspire M3800

Some ITEs have more than 3 independent FAN controller outputs. As the
initial implementation assumed only 3 outputs some registers are not
consequently numbered. This change adds macros for accessing those
registers.
Additionally some chips have SmartGuardian always enabled, without the
option for turning it off. For these chips bits that were responsible
for ON/OFF control are either reserved or have different meaning.
Another Kconfig option is added to disable ON/OFF functionality on
platforms that do not support it.
