* Support inverted ILIM_SEL for smart USB port powerDuncan Laurie2014-08-231-2/+9
| | | | | | | | | | | | | | Some platforms may have active low ILIM_SEL that is per-port and the output needs to be inverted.

* USB Power: Invert ILIM control line with 'smart simple' chargingDave Parker2014-07-171-3/+3
| | | | | | | | | | | | | | | | | | | The ILIM control line is inverted before reaching the USB charge controllers when they are cross-connected to allow only one port to deliver the HIGH current limit at a time.

* Add cprints() and ccprints()Vic Yang2014-05-211-2/+2
| | | | | | | | | | | | | | | | | | | | | Our code base contains a lot of debug messages in this pattern: CPRINTF("[%T xxx]\n") or ccprintf("[%T xxx]\n") The strings are taking up spaces in the EC binaries, so let's refactor this by adding cprints() and ccprints(). cprints() is just like cprintf(), except that it adds the brackets and the timestamp. ccprints() is equivalent to cprints(CC_CONSOLE, ...) This saves us hundreds of bytes in EC binaries.

* rambi: Leave 5V rail on in S3 if USB ports are poweredRandall Spangler2014-01-231-0/+13
| | | | | | | | | | | | | | | | | Previously, the 5V rail was disabled unconditionally in the S0->S3 transition. Now, the rail is left powered if one or both of the USB ports are powered. BUG=chrome-os-partner:25178 BRANCH=rambi TEST=Modify the OS to leave USB ports powered in S3. Then suspend. On the EC console, 'gpioget pp5000_en' should be 1.

* Rename mixed-case config constantsRandall Spangler2013-12-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | This renames constants used in compiler conditionals to uppercase. BOARD_foo CHIP_foo CHIP_FAMILY_foo CHIP_VARIANT_foo CORE_foo Mixed-case constants are still defined by the makefile, but are now no longer used. I will make one more pass in a week or so to catch any that are part of someone else's CL, since otherwise this change might silently merge correctly but result in incorrect compilation. Then I will remove defining the mixed-case constants. BUG=chromium:322144 BRANCH=none TEST=Build all boards. Also, "git grep 'BOARD_[a-z]'" should return no results (similarly for CHIP, CORE, etc.) Change-Id: I6418412e9f7ec604a35c2d426d12475dd83e7076 Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/179206 Reviewed-by: Vic Yang <victoryang@chromium.org> Reviewed-by: Bill Richardson <wfrichar@chromium.org>

| | | | | | | | | | | | | | | | | | | | | Link is the only platform that uses smart usb ports. Link's board.h defines USB_CHARGE_PORT_COUNT, yet the usb_port_power_smart.c file is peppered with assumptions that that constant is always 2.
