2015-06-04xhci: tegra: run firmware log thread only if needJC Kuo
Driver doesn't need to run a kernel thread to collect firmware log if release build firmware is loaded. Only debug build firmware is capable of generating logs. This commit checks firmware CFGTBL to know whether a firmware generates logs or not. bug 1487603 Change-Id: I8b147710dae58332d68625fedd3173e2d2f6074b Signed-off-by: JC Kuo <jckuo@nvidia.com> Reviewed-on: http://git-master/r/663769 (cherry picked from commit bc339c3a63ea18fbbe568c99e33d06d637ad1f71) Reviewed-on: http://git-master/r/744725 GVS: Gerrit_Virtual_Submit Tested-by: Mark Kuo <mkuo@nvidia.com> Reviewed-by: WK Tsai <wtsai@nvidia.com> Reviewed-by: Bibek Basu <bbasu@nvidia.com> Reviewed-by: Matthew Pedro <mapedro@nvidia.com> Reviewed-by: Ashutosh Jha <ajha@nvidia.com>

Loading firmware from filesystem takes much time. Enabing vbus regualtor before loading firmware will cause the time gap between vbus ON and host controller ready too large. So, we move the time of firmware loading earlier.

2013-09-16xhci: tegra: support hsic pretend connectJC Kuo
When HSIC port is being used to connect some HSIC device which gets powered-on before Tegra XUSB does, the HSIC CONNECT signal sent by device is likely missed. In addition, HSIC device isn't likely to resend CONNECT. Tegra XUSB supports "hsic pretend connect" which means firmware can manually direct HSIC ports from "RxDetect" to "Polling". We added one firmware mailbox message for this purpose. That allows driver to makeup for the missed CONNECT. bug 1341852 Change-Id: Ibf87b4790ce587f37f4f46cb660c25782562cccb Signed-off-by: JC Kuo <jckuo@nvidia.com> Reviewed-on: http://git-master/r/267195 Reviewed-by: Sachin Nikam <snikam@nvidia.com> Tested-by: Sachin Nikam <snikam@nvidia.com>

2013-09-16xhci: tegra: fix host partition powergate sequenceJC Kuo
System hang observed during elpg entry/exit stress test. Root cause is that xhci-tegra doesn't follow host partition powergating sequence illustrated by PG. "flushing MCCIF and partition clients" needs to be done before assserting RESET and disabling partition clocks. This change fixes the sequence by removing fews steps since those are supposed to be done by tegra_powergate_partition(). bug 1348646 Change-Id: Iae82e5cba2b5ceb09b6b5e6af6641736dc9ba855 Signed-off-by: JC Kuo <jckuo@nvidia.com> Reviewed-on: http://git-master/r/267292 Reviewed-by: Sachin Nikam <snikam@nvidia.com> Tested-by: Sachin Nikam <snikam@nvidia.com>

2013-09-14xhci: tegra: fix a race during usb2 remote wakeupHenry Lin
For usb2 devices, a race condition between remote and host wake was observed during remote wake from LP0. If usb2 remote wake's port status change event interrupt happens while the hub driver is resuming the same usb2 port for host wake, the hub driver may disconnect the usb2 port and cause the resuming_ports flag for usb2 remote wake not cleared properly. Then, the system cannot go to LP0 with "xhci_bus_suspend failed -16" error message. This patch fix the race by letting remote wake being completed before hub driver performs host resume for usb2 port.
