In this case the original base need to be restore before calling iounmap to unmap the proper address.

We're adjusting the timer's base for each per-CPU timer to point to the
actual start of the timer since device-tree defines a compound registers
range that includes all of the timers. In this case the original base
need to be restore before calling iounmap to unmap the proper address.

clocksource/drivers/tegra: Add Tegra210 timer support 2019-02-23T11:13:45+00:00 Joseph Lo josephl@nvidia.com 2019-02-21T07:21:44+00:00 b4822dc7564f007e7a9b5188b791b7a923e34104 Add support for the Tegra210 timer that runs at oscillator clock (TMR10-TMR13). We need these timers to work as clock event device and to replace the ARMv8 architected timer due to it can't survive across the power cycle of the CPU core or CPUPORESET signal. So it can't be a wake-up source when CPU suspends in power down state. Also convert the original driver to use timer-of API.
