2014-11-26usb: chipidea: add hw_wait_phy_stable for getting stable statusPeter Chen1-8/+16
The phy needs some delay to output the stable status from low power mode. And for OTGSC, the status inputs are debounced using a 1 ms time constant, so, delay 2ms for controller to get the stable status(like vbus and id) when the phy leaves low power.

2014-11-03usb: chipidea: add support to the generic PHY frameworkAntoine Tenart1-18/+65
This patch adds support of the PHY framework for ChipIdea drivers. Changes are done in both the ChipIdea common code and in the drivers accessing the PHY. This is done by adding a new PHY member in ChipIdea's structures and by taking care of it in the code.

2014-04-24usb: chipidea: add proper delay for waiting correct PHY statusPeter Chen1-13/+13
After the PHY has powered and initialized, it needs some delay for controller to reflect PHY's status. Some status and values for id, vbus, dp/dm are only stable after this delay. The current code tries to clear id/vbus status without enough delay, it causes the status are not cleared properly. This patch add 2ms delay after phy has initialized, and clear the unexpected status after that.

2014-04-24usb: chipidea: coordinate usb phy initialization for different phy typePeter Chen1-3/+34
For internal PHY (like UTMI), the phy clock may from internal pll, it is on/off on the fly, the access PORTSC.PTS will hang without phy clock. So, the usb_phy_init which will open phy clock needs to be called before hw_phymode_configure. See: http://marc.info/?l=linux-arm-kernel&m=139350618732108&w=2 For external PHY (like ulpi), it needs to configure portsc.pts before visit viewport, or the viewport can't be visited. so phy_phymode_configure needs to be called before usb_phy_init. See: cd0b42c2a6d2a74244f0053f8960f5dad5842278 It may not the best solution, but it can work for all situations.

fails Commit 40dcd0e ("usb: chipidea: add PTW, PTS and STS handling") introduced the following code to the ci_hdrc_probe() function: + if (!dev->of_node && dev->parent) + dev->of_node = dev->parent->of_node; This inadvertently associates the ci_hdrc device with the ci_hdrc_imx driver (which created the ci_hdrc device in the first place). This results in ci_hdrc_imx_probe() being run for the ci_hdrc device if ci_hdrc_probe() fails for some reason. ci_hdrc_imx_probe() will happily create a new ci_hdrc platform_device whose probing will likewise fail and trigger a new invocation of ci_hdrc_imx_probe() ... ad nauseam.
