02:58 <suniel> Hi, I have a roc-rk3399-pc board based on rk3399 SOC. The board has three on-board leds.one of the led is assigned to emmc for disk activity.My requirement is that i want to use the same led to turn it on at boot to indicateboard is powered up. Can I use/assign an LED resource for two seperate events, one LED is on from boot indicatingboard is

02:58 <suniel> powered and the other for emmc disk activity ? Thanks

06:11 <inode> suniel: if you're using gpio-leds, did you try assigning default-state to "on" for the led's node?

06:39 <suniel> yes i am using gpio-leds and yes i assigned default-state to "on", but it was off during boot

06:39 <inode> active low/high set correctly?

06:39 <suniel> yes

06:40 <suniel> but when i replace it with linux,default-trigger = "default-on", then the led was on during the boot process and then

06:42 <suniel> earlier it was linux,default-trigger = "mmc1" (emmc)

11:21 <robmur01_> I'm not 100% sure it's as bullet-proof as GPIO hogs, but at least the out-of-band enables are conceptually associated with the device, which is nice

11:23 <robmur01_> (that particular example is a hard-wired on-board USB endpoint which needs powering up externally)

11:28 <inode> rubmur01_: thanks! that's fitting with what i was trying to achieve

11:29 <inode> to enable an sdio wlan module
