2011-06-17tegra: dc: set HDMI clock to 0 if HDMI unpluggedtegra-10.11.10Xin Xie
HDMI clock is not auto dvfs, so we need set the clock rate to 0 if HDMI is disabled. Otherwise the Vdd core voltage will be always 1.2v even after HDMI cable unplugged.

2011-06-16usb: gadget: composite: Allow function drivers to pause control transfersRakesh Bodla
Some USB function drivers (e.g. f_mass_storage.c) need to delay or defer the data/status stages of standard control requests like SET_CONFIGURATION or SET_INTERFACE till they are done with their bookkeeping and are actually ready for accepting new commands to their interface. They can now achieve this functionality by returning USB_GADGET_DELAYED_STATUS in their setup handlers (e.g. set_alt()). The composite framework will then defer completion of the control transfer by not completing the data/status stages. This ensures that the host does not send new packets to the interface till the function driver is ready to take them. When the function driver that requested for USB_GADGET_DELAYED_STATUS is done with its bookkeeping, it should signal the composite framework to continue with the data/status stages of the control transfer. It can do so by invoking the new API usb_composite_setup_continue(). This is where the control transfer's data/status stages are completed and host can initiate new transfers. The DELAYED_STATUS mechanism is currently only supported if the expected data phase is 0 bytes (i.e. w_length == 0). Since SET_CONFIGURATION and SET_INTERFACE are the only cases that will use this mechanism, this is not a limitation.

2011-05-27serial-core: keep value of console cflag in uart_update_termiosAlexandre Courbot
uart_update_termios is called on console resume and restores the line parameters using cons->cflag before resetting it. However code in uart_resume_port does the same afterwards, applying a 0 value to the port's cflag and erasing the correct setting. This patch preserves the value of cflag in uart_update_termios to prevent this and allow the serial console to restore properly even if there is no program using it on user side. Serial code has been largely refactored upstream in the upstream kernel and faulty code apparently removed.

2011-05-09serial: core: Restore termios settings on resume console portsVandana Salve
The commit 4547be7 rewrites suspend and resume functions. According to this rewrite, when a serial port is a printk console device and can suspend(without set no_console_suspend flag), it will definitely call set_termios function during its resume, but parameter termios isn't initialized, this will pass an unpredictable config to the serial port. If this serial port is not a userspace opened tty device , a suspend and resume action will make this serial port unusable. I.E. ttyS0 is a printk console device, ttyS1 or keyboard+display is userspace tty device, a suspend/resume action will make ttyS0 unusable. If a serial port is both a printk console device and an opened tty device, this issue can be overcome because it will call set_termios again with the correct parameter in the uart_change_speed function. Refer to the deleted content of commit 4547be7, revert parts relate to restore settings into parameter termios. It is safe because if a serial port is a printk console only device, the only meaningful field in termios is c_cflag and its old config is saved in uport->cons->cflag, if this port is also an opened tty device, it will clear uport->cons->cflag in the uart_open and the old config is saved in tty->termios. refer http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.37.y.git; a=commit;h=891b9dd10764352926e1e107756aa229dfa2c210 cherry-pick the changes from the kernel 2.6.37 commit id :891b9dd10764352926e1e107756aa229dfa2c210 Cherry-picked http://git-master/r/#change,20302 Bug 819016 Change-Id: Ic7ce0a6d595c0e1f65285d7978db93be12158f0f Reviewed-on: http://git-master/r/30680 Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com> Tested-by: Bharat Nihalani <bnihalani@nvidia.com>

Having the device resume and suspend when the cable is not present is an overhead for the system. Hence removed resume and device function calls when the cable is not present.

2011-05-04tegra:otg: Fix clock disable to match ref countBitan Biswas
usbd clock is enabled during the probe and not disabled after the functionality. Due to this clock reference count is non-zero and hence usbd clock is not disabled during suspend. Fixed this by disabling clock appropriately. - Since clocks are now turned off during suspend clock needs to be enabled during fsl_udc_resume.
