Subject: [PATCH/RFT 02/12] ARM: davinci: hawk: add full constraints for ohci plat boot
Date: Fri, 7 Oct 2016 18:42:47 +0200 [thread overview]
Message-ID: <1475858577-10366-3-git-send-email-ahaslam@baylibre.com> (raw)
In-Reply-To: <1475858577-10366-1-git-send-email-ahaslam-rdvid1DuHRBWk0Htik3J/w@public.gmane.org>
From: Axel Haslam <ahaslam-rdvid1DuHRBWk0Htik3J/w@public.gmane.org>
The phy framework requests an optional "phy" regulator. If it does
not find one, it returns -EPROBE_DEFER. In the case of non-DT based boot
for the omap138-lcdk board, this would prevent the usb11 phy to probe
correctly and ohci would not enumerate.
By calling "regulator_has_full_constraints", An error would be returned
instead of DEFER for the "optional" regulator, and the probe of
the phy driver can continue normally without a regulator.
