| * usb: phy: tegra: Avoid use of sizeof(void)Thierry Reding2014-09-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PHY configuration is stored in an opaque "config" field, but when allocating the structure, its proper size needs to be known. In the case of UTMI, the proper structure is tegra_utmip_config of which a local variable already exists, so we can use that to obtain the size from. Fixes the following warning from the sparse checker: drivers/usb/phy/phy-tegra-usb.c:882:17: warning: expression using sizeof(void) Fixes: 81d5dfe6d8b3 (usb: phy: tegra: Read UTMIP parameters from device tree) Cc: stable@vger.kernel.org Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

On bootup, with the existing code and runtime pm enabled, the driver would decrement the pm usage count without checking the current state of the phy. This pm usage count decrement would trigger the runtime pm which than would abort the usb enumeration which was in progress.

The SOC has 2 PHYs which can be used with the OTG port, and this code allows configuring the correct one. Note: This resolves the problem I was seeing where I couldn't get the USB driver working at all on a dragonboard, from cold boot. This patch depends on patch 5/14 from Ivan's msm USB patch set. It does not use DT for the register address, as there's no evidence that this address changes between SoC versions. Signed-off-by: Tim Bird <tim.bird@sonymobile.com> Signed-off-by: Ivan T.

It is used to reset USB PHY after putting USB PHY into low power mode and for calibration of USB PHY. Putting USB PHY into low power mode is causing ulpi read/write timeout as expected. USB PHY reset clk is not available on newer platform. For 28nm PHY, reset USB PHY after resetting USB LINK. Also reset USB PHY using USB_PHY_PON bit with USB_OTG_HS_PHY_CTRL register after programming USB PHY Override registers as suggested with hardware programming guidelines. Signed-off-by: Ivan T.
