Tegra194 supports the same reset levels as Tegra186 but extends the set of reset sources. Provide custom PMC register definitions to account for the larger field for the reset sources as well as the updated list of reset sources.

The removed barrier isn't needed because writes/reads are strictly ordered and even if PMC had separate ports for writes, it wouldn't matter since the hardware logic takes into effect after triggering CPU's power-gating and at that point all CPU accesses are guaranteed to be completed. That barrier was copied from the old arch/ code during transition to the soc/ PMC driver and even that the code structure was different back then, the barrier didn't have a real useful purpose from the start. Lastly, the tegra_pmc_writel() naturally inserts wmb() because it uses writel(), and thus this change doesn't actually make any difference in terms of interacting with hardware. Hence let's remove the barrier to clean up code a tad. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>

Add regulators coupler for Tegra30 SoCs that performs voltage balancing of a coupled regulators and thus provides voltage scaling functionality. There are 2 coupled regulators on all Tegra30 SoCs: CORE and CPU. The coupled regulator voltages shall be in a range of 300mV from each other and CORE voltage shall be higher than the CPU by N mV, where N depends on the CPU voltage.

Add regulators coupler for Tegra20 SoCs that performs voltage balancing of a coupled regulators and thus provides voltage scaling functionality. There are 3 coupled regulators on all Tegra20 SoCs: CORE, RTC and CPU. The CORE and RTC voltages shall be in range of 170mV from each other and they both shall be higher than the CPU voltage by at least 120mV. This sounds like it could be handle by a generic voltage balancer, but the CORE voltage scaling isn't implemented in any of the upstream drivers yet. It will take quite some time and effort to hook up voltage scaling for all of the drivers, hence we will use a custom coupler that will manage the CPU voltage scaling for the starter.

Tegra210 and prior Tegra chips have deep sleep entry and wakeup related timings which are platform specific that should be configured before entering into deep sleep. Below are the timing specific configurations for deep sleep entry and wakeup. - Core rail power-on stabilization timer - OSC clock stabilization timer after SOC rail power is stabilized. - Core power off time is the minimum wake delay to keep the system in deep sleep state irrespective of any quick wake event. These values depends on the discharge time of regulators and turn OFF time of the PMIC to allow the complete system to finish entering into deep sleep state. These values vary based on the platform design and are specified through the device tree. This patch has implementation to configure these timings which are must to have for proper deep sleep and wakeup operations.

AOWAKE model support is available for Tegra186 and Tegra194 only and it resides within PMC and supports tiered wake architecture.

Interrupts that don't have an associated wake event or GPIO wake events end up with an associate IRQ chip that is NULL and which causes IRQ code to crash. This is because we don't implicitly set the parent IRQ chip by allocating the interrupt at the parent. However, there really isn't a corresponding interrupt at the parent, so we need to work around this by setting the special no_irq_chip as the IRQ chip for these interrupts.

Merge active entropy generation updates. This is admittedly partly "for discussion". We need to have a way forward for the boot time deadlocks where user space ends up waiting for more entropy, but no entropy is forthcoming because the system is entirely idle just waiting for something to happen. While this was triggered by what is arguably a user space bug with GDM/gnome-session asking for secure randomness during early boot, when they didn't even need any such truly secure thing, the issue ends up being that our "getrandom()" interface is prone to that kind of confusion, because people don't think very hard about whether they want to block for sufficient amounts of entropy. The approach here-in is to decide to not just passively wait for entropy to happen, but to start actively collecting it if it is missing. This is not necessarily always possible, but if the architecture has a CPU cycle counter, there is a fair amount of noise in the exact timings of reasonably complex loads. We may end up tweaking the load and the entropy estimates, but this should be at least a reasonable starting point. As part of this, we also revert the revert of the ext4 IO pattern improvement that ended up triggering the reported lack of external entropy. * getrandom() active entropy waiting: Revert "Revert "ext4: make __ext4_get_inode_loc plug"" random: try to actively add entropy rather than passively wait for it

This reverts commit 72dbcf72. Instead of waiting forever for entropy that may just not happen, we now try to actively generate entropy when required, and are thus hopefully avoiding the problem that caused the nice ext4 IO pattern fix to be reverted.

For 5.3 we had to revert a nice ext4 IO pattern improvement, because it caused a bootup regression due to lack of entropy at bootup together with arguably broken user space that was asking for secure random numbers when it really didn't need to. See commit 72dbcf72 (Revert "ext4: make __ext4_get_inode_loc plug"). This aims to solve the issue by actively generating entropy noise using the CPU cycle counter when waiting for the random number generator to initialize. This only works when you have a high-frequency time stamp counter available, but that's the case on all modern x86 CPU's, and on most other modern CPU's too. What we do is to generate jitter entropy from the CPU cycle counter under a somewhat complex load: calling the scheduler while also guaranteeing a certain amount of timing noise by also triggering a timer. I'm sure we can tweak this, and that people will want to look at other alternatives, but there's been a number of papers written on jitter entropy, and this should really be fairly conservative by crediting one bit of entropy for every timer-induced jump in the cycle counter. Not because the timer itself would be all that unpredictable, but because the interaction between the timer and the loop is going to be. Even if (and perhaps particularly if) the timer actually happens on another CPU, the cacheline interaction between the loop that reads the cycle counter and the timer itself firing is going to add perturbations to the cycle counter values that get mixed into the entropy pool. As Thomas pointed out, with a modern out-of-order CPU, even quite simple loops show a fair amount of hard-to-predict timing variability even in the absense of external interrupts. But this tries to take that further by actually having a fairly complex interaction. This is not going to solve the entropy issue for architectures that have no CPU cycle counter, but it's not clear how (and if) that is solvable, and the hardware in question is largely starting to be irrelevant. And by doing this we can at least avoid some of the even more contentious approaches (like making the entropy waiting time out in order to avoid the possibly unbounded waiting).
