Subject: Atmel SoCs and the newly added CONFIG_DELAY_DEVICE_PROBES option
Date: Fri, 16 Oct 2015 20:11:29 +0200 [thread overview]
Message-ID: <20151016181129.GA1764@gradator.net> (raw)
Hi,
FYI, to save you a git bisect, the recently added
CONFIG_DELAY_DEVICE_PROBES (enabled by default) breaks Atmel SoCs.
For a few of quickly noticeable issues:
- PM is not working: at91_pm_sram_init: sram pool unavailable!
- Watchdog is not even probed
- on -ek boards the wm8904 is not probed either.
Disabling CONFIG_DELAY_DEVICE_PROBES fixes all issues.
Tomeu, what should I provide to help find out what's happening ?
Sylvain
