Date: Fri, 4 Jul 2014 04:09:37 +0300 From: Tuomas Tynkkynen <ttynkkynen@...dia.com> To: Alan Stern <stern@...land.harvard.edu> Cc: Stephen Warren <swarren@...dotorg.org>, Thierry Reding <thierry.reding@...il.com>, Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Felipe Balbi <balbi@...com>, linux-tegra@...r.kernel.org, linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-usb@...r.kernel.org, devicetree@...r.kernel.org, Tuomas Tynkkynen <ttynkkynen@...dia.com> Subject: [PATCH v2 2/4] ARM: tegra: Add resets & has-utmi-pad-registers flag to all USB PHYs Add new properties to all of the Tegra PHYs that are now required according to the binding. In order to stay compatible with old device trees, the USB drivers will still function without these reset properties but with the old, potentially buggy behaviour.
