* kblight: Add keyboard backlight control moduleDaisuke Nojiri2018-05-111-100/+21
| | | | | | | | | | | | | | | | | | | | | | | This patch promotes board/nami/keyboard_backlight.c to common directory. Board customization is done via board_kblight_init callback. It currently supports two drivers: direct PWM control and lm3509. Signed-off-by: Daisuke Nojiri <dnojiri@chromium.org> BUG=b:78360907,b:78141647 BRANCH=none TEST=On Nami (for lm3509) and Sona (pwm), verify the followings: 1. Alt + brightness up/down works 2. After suspend-resume, brightness is restored 3. Lid close/open 4. After screen is off, keyboard backlight is turned off Change-Id: I584c06e8702fe7b289999698f277311cfd3400bd Reviewed-on: https://chromium-review.googlesource.com/1051027 Commit-Ready: Daisuke Nojiri <dnojiri@chromium.org> Tested-by: Daisuke Nojiri <dnojiri@chromium.org> Reviewed-by: Daisuke Nojiri <dnojiri@chromium.org>
* cleanup: DECLARE_CONSOLE_COMMAND only needs 4 argsBill Richardson2016-08-241-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* pwm: Add common initialization for PWM pinsShawn Nematbakhsh2015-12-041-3/+0
| | | | | | | | | | | | | | | | | | | Rather than having various PWM module groups initialized from various HOOK_INIT functions, group them all into a single module and initialize them all from a common function in pwm.c.

* rambi: Control LEDs using PWMRandall Spangler2013-10-081-0/+130
Rambi has a pair of LEDs which are attached to the PWM fan controller. Add support for them. Also add a generic 'pwmduty' command which can be used to get/set the duty cycle for any PWM channel. Also fix rounding errors in pwm module, so that set/get duty doesn't keep rounding down. BUG=chrome-os-partner:22895 BRANCH=none TEST=Boot rambi. LEDs are off. pwmduty -> both are 0% pwmduty 0 10 -> green LED on dimly pwmduty 1 10 -> red LED on dimly pwmduty 0 99 -> green LED on brightly pwmduty 1 100 -> red LED on brightly pwmduty 1 0 -> red LED off pwmduty 1 -1 -> red LED turns back on because fan controller is disabled pwmduty -> channel 0 at 99%, channel 1 disabled Build all platforms. Pass all unit tests. Change-Id: Ib0a6289a757554e696a9a0153a85bdc34e2ee2ae Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/172094
