* cleanup: DECLARE_CONSOLE_COMMAND only needs 4 argsBill Richardson2016-08-241-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Since pretty much always, we've declared console commands to take a "longhelp" argument with detailed explanations of what the command does. But since almost as long, we've never actually used that argument for anything - we just silently throw it away in the macro. There's only one command (usbchargemode) that even thinks it defines that argument. We're never going to use this, let's just get rid of it. BUG=none BRANCH=none CQ-DEPEND=CL:*279060 CQ-DEPEND=CL:*279158 CQ-DEPEND=CL:*279037 TEST=make buildall; tested on Cr50 hardware Everything builds. Since we never used this arg anyway, there had better not be any difference in the result.

* btle: Improved stability of ble_tx functionLevi Oliver2016-08-171-0/+21
| | | | | | | | | | | | | | | | | | | | | ble_tx now resets values that could prevent its functioning. Since there is no NRF51 shortcut from TX->RX, it also blocks until packet is transmitted. This prevents calling RX before TX is completed, specifically in advertising state. Also added timeouts to prevent possibility of freezing in case of unexpected state. TEST=Used function before and after CL in a more fully implemented stack. This improved reliability.

By removing the irq_handler pointer out of the struct, we can save some space with some targets saving more than others. (For example, ~260 bytes for samus_pd). This change also brings about a new define: GPIO_INT(name, port, pin, flags, signal) And the existing GPIO macro has had the signal parameter removed since they were just NULL. GPIO(name, port, pin, flags) In each of the gpio.inc files, all the GPIOs with irq handlers must be defined at the top of the file. This is because their enum values from gpio_signal are used as the index to the gpio_irq_handlers table.

* I2C: Increase priority of i2c_initAlexandru M Stan2015-01-161-1/+1
| | | | | | | | | | | | | | | | Chipset sometimes needs I2C, therefore i2c_init should have a higher priority than power_common_init so i2c is available by the time the chipset might be talking to the battery.

* nrf51: Fix a race condition in hwtimer.cMyles Watson2015-01-141-17/+9
| | | | | | | | | | | | | | | | | | | | | | | | | The check for overflow was originally in __hw_clock_source_read() If it got interrupted, it would frequently see an overflow, because "prev_read" would be less than "now". 1 - Use the comparator to check for overflow. 2 - Only check for overflow in the interrupt handler. BUG=chrome-os-partner:35312 BRANCH=none TEST=make buildall -j use the keyboard code to type use a console command "forcetime", to force the system time to overflow soon.
