Subject: [PATCH] dm: core: Show driver name with 'dm tree'
It is often useful to see which driver was actually selected for each
device. Add a new 'Driver' column to provide this information. Sample
output:
Class Probed Driver Name
----------------------------------------
root [ + ] root_drive root_driver
keyboard [ + ] i8042_kbd |-- keyboard
serial [ + ] ns16550_se |-- serial
rtc [ ] rtc_mc1468 |-- rtc
timer [ + ] tsc_timer |-- tsc-timer
syscon [ + ] ich6_pinct |-- pch_pinctrl
pci [ + ] pci_x86 |-- pci
northbridge [ + ] bd82x6x_no | |-- northbridge@0,0
video [ + ] bd82x6x_vi | |-- gma@2,0
vidconsole0 [ + ] vidconsole | | `-- gma@2,0.vidconsole0
