* servo_micro: add parity settingNick Sanders2017-07-131-6/+50

* common/update_fw: Remove board-specific rw_sectionsNicolas Boichat2017-04-151-21/+0
| | | | | | | | | | | | | | | | | | | | | | rw_sections is defined in the exact same way on all common code boards, let's remove it, and hard-code the values in update_fw.c instead. Take this as an opportunity to fold set_valid_section in fw_update_start (this will be useful later on, as we also want to return the inactive region version).

| | | | | | | | | | | | | | | | | | | Let's split the usb headers in 3 different parts, instead of having usb_descriptor.h pull in usb_hw.h and usb_api.h. - usb_api.h: EC functions related to usb (e.g. connect/disconnect) - usb_descriptor.h: common USB names and structures - usb_hw.h: Functions required for interactive with EC's USB HW BRANCH=none BUG=b:35587171 TEST=make buildall -j Change-Id: I37ead61e3be5e7ae464f1c9137cf02eaab0ff92e Reviewed-on: https://chromium-review.googlesource.com/454861 Commit-Ready: Nicolas Boichat <drinkcat@chromium.org> Tested-by: Nicolas Boichat <drinkcat@chromium.org> Reviewed-by: Vincent Palatin <vpalatin@chromium.org>
* cr50: Have INAs and I2Cm enabled when rdd is attachedScott2017-02-061-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The INAs are only used for development and testing purposes. Therefore, the 3.3V rail to the INAs is off by default and the I2Cm module is not enabled. Enabling INA power and connecting the I2Cm module was done at the beginning of each USB to I2C request. The problem with this approach is that INA measurments didn't always succeed due to not enough time for the INAs to initialize. Rather than add some arbitrary delay, it is better to tie the INAs to when rdd is attached/detached. It is only when rdd is attached that the INAs will be accessed, so there is no need to enable/disable for each individual I2C transaction. This CL ties the enabling/disabling of the INA and I2Cm module to the rdd state. This change makes the previous use of usb_i2c_board_enable() and usb_i2c_board_disable() obslete. BRANCH=none BUG=chrome-os-partner:62375 TEST=manual Connect servo with suzyq connected: sudo servod -p 0x5014 -b eve -c eve_r0_inas.xml Then execute single INA reads dut-control pp3300_dx_edp_mv and verify that it returns meaningful numbers. Without this CL single reads via dut-control would always return 0.

* Remove Makefile symlinks under board directoryDaisuke Nojiri2016-07-091-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | This feature is inconsistent. Not all boards have such a symlink (for a obvious reason). This feature is fragile. It's most likely not tested and going to be broken if not already. Developers won't like it if they have to test two different ways to build boards before submitting patches. This feature is not necessary. If you build EC in the standard way (e.g. make BOARD=samus), these symlinks are not needed. This feature is wasteful. Extra disk spaces are used and extra lines are added to Makefile (increasing code complexity slightly).

* servo_micro: add gpio mode get and setNick Sanders2016-04-271-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | GPIO console commands currently only show input voltage level, and can only set level on predefined outputs. This change allows GPIOs to be cycled between output, input, and alternate function, as well as displaying the mode and asserted level (if any) in gpioget. This change creates CONFIG_CMD_GPIO_EXTENDED as the internal gpio interface needs to be changed to support this, and I can't test the other architectures. It may be worthwhile to add this for all, or not. This change is also necessary also for servo micro JTAG and PD UART support, as several pins are tied together on the flex and stm32 outputs need to be variously active or in high-z depending on mode.
