* soc/tegra: pm-tegra210: use atomic lock for RTSumit Gupta2019-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For RT, changing "tegra210_cpu_pm_lock" from RWLOCK to RAW_SPINLOCK. RWLOCK in PREEMPT_RT_FULL becomes sleeping lock which triggers BUG(). Changing it to RAW_SPINLOCK to use atomic lock.

Allocating extra memory. ** ** ** ** This means that this is a DEBUG kernel and it is ** ** unsafe for production use. ** ** ** ** If you see this message and you are not debugging ** ** the kernel, report this immediately to your vendor! ** ** ** ** NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE ** ********************************************************** commit 2184db46e425 tracing: Print nasty banner when trace_printk() is in use has the rationale: Since trace_printk() should only be used for debugging purposes, there's no reason to waste memory on these buffers on a production system. That means, trace_printk() should never be used unless a developer is debugging their kernel. There's macro magic to allocate the buffers if trace_printk() is used anywhere in the kernel. replace trace_printk with pr_debug. If these debug prints are desired, a specialized trace event should be defined and used.

* soc/tegra: Fix misuse of tegra_bpmp_send_receiveNicolin Chen2018-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | The driver is supposed to call tegra_bpmp_send_receive() functions to send mails to bpmp firmware without caring about return values. However, the two function calls in the driver put the input mails as output parameters while leaving the input parameters to NULL. (Note: input means Kernel -> bpmp; output means bpmp -> kernel) This creates a problem that bpmp doesn't receive the correct mail. So this change just simply fixes the bug.

* soc: tegra: Move kfuse driver to linux-nvidiaMikko Perttunen2018-05-22

As such, move it to the linux-nvidia to reduce duplication.

* soc: tegra: Add rudimentary BPMP DVFS driverAlex Frid2018-05-17
Added BPMP DVFS driver to provide kernel access to some useful properties of V/F relations for clocks manged by BPMP-FW. For now, the only exposed property is maximum clock frequency that is guaranteed to be reached at/below Vmin at any temperature.
