interconnect: qcom: rpm: Prevent integer overflow in rate

2022-01-27T11:02:34+00:00

[ Upstream commit a7d9436a6c85fcb8843c910fd323dcd7f839bf63 ]

Using icc-rpm on ARM32 currently results in clk_set_rate() errors during
boot, e.g. "bus clk_set_rate error: -22". This is very similar to commit
7381e27b1e56 ("interconnect: qcom: msm8974: Prevent integer overflow in rate")
where the u64 is converted to a signed long during clock rate rounding,
resulting in an overflow on 32-bit platforms.

Let's fix it similarly by making sure that the rate does not exceed
LONG_MAX. Such high clock rates will surely result in the maximum
frequency of the bus anyway.

interconnect: icc-rpm: add support for QoS reg offset

2021-10-04T11:13:58+00:00

SDM660 driver expects to have QoS registers at the beginning of NoC
address space (sdm660 platform shifts NoC base address). Add support for
using QoS register offset, so that other platforms do not have to change
existing device trees.
