-Subject: [PATCH] realtek: resurrect timer driver
-
-Now that we provide a clock driver for the Reltek SOCs the CPU frequency might
-change on demand. This has direct visible effects during operation
-
-- the CEVT 4K timer is no longer a stable clocksource
-- after CPU frequencies changes time calculation works wrong
-- sched_clock falls back to kernel default interval (100 Hz)
-- timestamps in dmesg have only 2 digits left

-[    0.000000] sched_clock: 32 bits at 100 Hz, resolution 10000000ns, wraps ...

-Looking around where we can start the CEVT timer for RTL930X is a good basis.
-Initially it was developed as a clocksource driver for the broken timer in that
-specific SOC series. Afterwards it was shifted around to the CEVT location,
-got SMP enablement and lost its clocksource feature. So we at least have
-something to copy from. As the timers on these devices are well understood
-the implementation follows this way:
-
-- leave the RTL930X implementation as is
-- provide a new driver for RTL83XX devices only
-- swap RTL930X driver at a later time
-
-Like the clock driver this patch contains a self contained module that is SOC
-independet and already provides full support for the RTL838X, RTL839X and
-RTL930X devices. Some of the new (or reestablished) features are:
-
-- simplified initialization routines
-- SMP setup with CPU hotplug framework
-- derived from LXB clock speed
-- supplied clocksource
-- dedicated register functions for better readability
-- documentation about some caveats
