usb: typec: fusb302: fix "op-sink-microwatt" default that was in mW

2020-01-22T09:13:03+00:00

commit 8f6244055bd3 ("usb: typec: fusb302: Always provide fwnode for the
port") didn't convert this value from mW to uW when migrating to a new
specification format like it should have.

USB-PD tcpm: bad warning+size, PPS adapters

2020-01-02T16:39:01+00:00

Augmented Power Delivery Objects (A)PDO_s are used by USB-C
PD power adapters to advertize the voltages and currents
they support. There can be up to 7 PDO_s but before PPS
(programmable power supply) there were seldom more than 4
or 5. Recently Samsung released an optional PPS 45 Watt power
adapter (EP-TA485) that has 7 PDO_s. It is for the Galaxy 10+
tablet and charges it quicker than the adapter supplied at
purchase. The EP-TA485 causes an overzealous WARN_ON to soil
the log plus it miscalculates the number of bytes to read.

So this bug has been there for some time but goes
undetected for the majority of USB-C PD power adapters on
the market today that have 6 or less PDO_s. That may soon
change as more USB-C PD adapters with PPS come to market.

Tested on a EP-TA485 and an older Lenovo PN: SA10M13950
USB-C 65 Watt adapter (without PPS and has 4 PDO_s) plus
several other PD power adapters.

usb: typec: fusb302: Fix an undefined reference to 'extcon_get_state'

2019-12-17T15:02:49+00:00

Fixes the following compile error:

drivers/usb/typec/tcpm/fusb302.o: In function `tcpm_get_current_limit':
fusb302.c:(.text+0x3ee): undefined reference to `extcon_get_state'

make: *** [vmlinux] Error 1

It is because EXTCON is build as a module, but FUSB302 is not.

All configuration can and should be done through fwnodes instead of
through the tcpc_config struct and there are no existing users left of
struct tcpc_config, so lets remove it.

The "port->typec_caps.data" and "port->typec_caps.type" variables are
enums and in this context GCC will treat them as an unsigned int so they
can never be less than zero.
