* npcx: adc: Properly wait for conversion interruptMulin Chao2016-08-101-17/+7
| | | | | | | | | | | | | | | | | | | | Certain tasks (eg. chipset) may be woken directly by other tasks / unrelated interrupts. Add an explicit wake event for ADC conversion done so that we're not mistakenly woken. BUG=chrome-os-partner:54971 BRANCH=None TEST=Manual on kevin rev5, run "reboot ap-off" then "sysjump rw", verify console isn't spammed with GPIO warning message due to ADC failure to read board version.

* npcx: Adjust relative IRQ priorities for high-priority UARTShawn Nematbakhsh2016-08-071-1/+1
| | | | | | | | | | | | | | | | | | | Our UART interrupt must be able to preempt our SHI_CS interrupt, otherwise console input may be lost. Adjust our relative IRQ priorities to accommodate this. BUG=chrome-os-partner:55920 BRANCH=None TEST=Run `echo "kbpress 11 4 1" > /dev/pts/17` on kevin 200 times from the recovery screen, verify that all input is received by the EC.

* servo_v4: Fix ADC console commandNick Sanders2016-05-261-19/+0
| | | | | | | | | | | | | | | | | | | | | | The console adc command prints adc values in the order they appear in hardware, however they are lableled in the order they are enumerated in board.h, which is not necessarily the same. This prints the correct name and value pairs, and removes the adc_read_all_channels function which is not otherwise used. BUG=chromium:571476 BRANCH=None TEST="adc" command associates correct values with names now.

* common: adc/i2c: Mark task_waiting volatileShamile Khan2015-12-011-1/+1
| | | | | | | | | | | | | | | | | | | When Link Time Optimization is turned on, functions that set task_waiting multiple times have one of the sets removed by the linker leading to undesired results. Marking task_waiting volatile alleviates this issue. BUG=chrome-os-partner:46063 TEST=Manually tested on Kunimitsu. Console command adc shows correct value of approx 20000 mV for VBUS.

* nuc: Simplify adc/pwm/fan drivers and related structures in boardsMulin Chao2015-09-291-19/+10
| | | | | | | | | | | | | | | | | | | Modified drivers: 1. register.h: Add marco field operation funcs for muti-bits field of register. 2. adc.c/fan.c/pwm.c: Simplify field operations by marco funcs. 3. adc.c: Add support for ADC_CH3/4 4. pwm.c: Add PWM_CONFIG_DSLEEP_CLK flag 6. fan.c: Support multi-fans mechanism BUG=chrome-os-partner:34346 TEST=make buildall -j; test nuvoton IC specific drivers BRANCH=none Change-Id: Iaaeb6c4ae8d55b4245a1cefb9c20feae4c0fdec2 Reviewed-on: https://chromium-review.googlesource.com/300673 Commit-Ready: Mulin Chao <mlchao@nuvoton.com> Tested-by: Mulin Chao <mlchao@nuvoton.com> Reviewed-by: Randall Spangler <rspangler@chromium.org>

* WIP - Nuvoton 30-Jan patchRandall Spangler2015-02-251-7/+4

Change cycle_pluses to 480 in board.c Issues fixed: 1. Jump data at top of RAM is getting corrupted. Changed the flag to RESET_FLAG_RESET_PIN. Added a workaround method to fix VCC1_RST issue. 2. Hibernate wake need to report whether wake reason was GPIO or RTC 3. Hibernate wake must be distinguishable from watchdog reset. The booter will log reset reason in Code RAM. I copy the log data to battery-backup RAM in little FW. And system driver will refer this data to distinguish if it's watchdog reset or not. 4. Watchdog reset flag is not set. Same fix as 3. 5. Should return error if unable to clear SPI flash status register. 6. Remove chip_temp_sensor.c 7. Remove use of pstate from flash driver 8. Remove support for watchdog warm reset 9. Keyboard raw driver must support COL2 inverted 10. LPC memory mapped data must be read-only from host 11. LPC should support PLTRST# signal 12. Problems reading chip type/version. Use core registers and ROM data to read IDs. 13. When chip type/version is unknown, report hex value. 14. Watchdog does not consistently print panic information. 15. Remove console force enable logic. 16. Enable only the peripheral clocks that are needed. Please notice user should add bit mask in CGC_XXX_MASK if they want to enable additional module. For example, if user wants to enable PWM3, he must add PWDWN_CTL2_PWM3_PD bit in CGC_PWM_MASK. Please see HOOK_FREQ_CHANGE and HOOK_INIT these two hook functions. If I turn off all I2C modules in system_pre_init and turn on the modules I need in i2c_init, I found its freq is not correct. The root cause is hook_notify(HOOK_FREQ_CHANGE) is executed first (in clock_init) before i2c_init. At this time, i2c modules are power-down and writing to freq register is useless. I re-execute freq-changed hook function after turning on modules again. 17. MPU properly configured to prevent code execution from data RAM 18. Partial nvcontext implementation. Copy these 16 bytes in our battery-backup RAM. Additional items we also modified: 1. pwm.c: Support open-drain IO type of PWM. (PWM IO-Type cannot by determined by GPIO, we use bit 1 & 2 of function byte of gpio_alt_func array to support it) 2. ec_npcxflash.c: Use definition to replace constant value. Stop watchdog during flash programing. 3. npcx_cmds.tcl: Adjust script sequence for robustness. Add unlock MPU commands for Data RAM.
