Set the register values for each of the board files to keep the Core voltage to 0.95V in LP1. This change is only for those platforms where LP1 is supported. Enterprise and Kai are the main platforms for this change. There is no support for Cardhu for LP1 and so is left blank and the feature will be skipped for Cardhu platforms, except for AP37. AP37 with a PM269 board needs this change and so Cardhu board file is updated with the values specific to AP37.

2012-08-29arm: tegra: Set Core to 0.95V in LP1Karthik Ramakrishnan
When the device prepares for LP1, the Core voltage is set to the highest value(1.2V for Enterprise and Kai, and 1.3V for AP37 and Cardhu). This is to set for some of the driver suspend along the sequence need a higher emc frequency and thus a higher Core voltage. Since the sequence of drivers suspend depends on the sequence of their registration in the table, which in turn is platform-dependent, there is no right place in the LP1 entry path where the Core voltage can be set to a lower voltage. Hence, the Core voltage remains high in LP1 resulting in higher power. Thus, the only safe location where the Core voltage can be lowered is once all the drivers are suspended and the DRAM is set in self-refresh, at the final point just before the system is suspended in the IRAM code. This location at the assembly code ensures that no other module will be running and thus that nothing will require a higher core voltage. The Core is set to the lowest possible value since nothing requires it. It is then restored to the highest voltage as soon as the LP1 resume code is started so that all drivers are resumed safely. At the execution point in IRAM during LP1 suspend path, even the I2C clocks are gated. They must be reset first and then the I2C transaction is performed. An I2C transaction involves 4 bytes of data, to send the slave address, the Core voltage register address and 2 bytes of data which has the value to set the voltage(the second byte is not required for this transaction). Once these registers are set, the I2C transaction is performed by setting the I2C transaction register to 0xA02. After sending the I2C transaction, we wait for about 250us to check the status of the transaction and if not updated, wait for more time to check again. If after 2ms and the transaction fails to register, the transaction is aborted and the device is allowed to enter at high voltage. Since the failure rate of I2C transaction is very low at this point in execution where there will be no conflicts in the bus, it is okay to have Core high for some of the LP1 cycles. However, it is unacceptable for the I2C transaction to fail on the way from LP1 resume since the device cannot come up with a lower Core voltage. In this case, the transaction is retried again and again till it is successful. There is no way but to keep trying as the device would fail to resume with Core at 0.95V. Each platform(or each PMU) has different values for the I2C transaction ie. slave address, Core voltage register and the value to set the voltage. For the device in IRAM, it cannot access anything in SDRAM memory, these values needs to be pushed to IRAM memory before the device starts execution in IRAM. This is done during initialization of suspend code when it picks values from the board files and copies it to IRAM part of code, before the whole memory is copied to IRAM. This new feature is controlled by a KConfig variable TEGRA_LP1_950 which should be enabled once the board file of the device is updated with the right values. The device hangs when it does not have the right values for the I2C transaction. With this change in Core, LP1 power is reduced by 12mW in Enterprise, 20mW in AP37 and about 24mW in Kai.

2012-08-27video: tegra: nvmap: fix handle usecount trackingTuomas Tynkkynen
A handle's usecount used to be incremented once during the mmap ioctl, and decremented when the mapping is closed by the kernel. However, that fails if a mapping cloned, for example if the mapping was split due to a munmap, or (presumably) during fork, as the decrement will then happen for each cloned mapping. Therefore increment the usecount when a mapping is opened. Also fix a BUG_ON() that would have caught this bug, if it wouldn't have done the check by checking if the unsigned usecount field is less than zero.
