Hi.
When I was testing my clk driver + generic cpufreq driver, I was hit by a problem. Everything worked fine on my 64-bit SoCs, but not on 32-bit SoCs. I found the cause of the problem was that the type of clk_rate is "long". It is long enough on 64-bit systems, but only 32-bit wide on 32-bit systems. The CPU clocks on my SoCs are derived from a 2.4GHz PLL. The .round_rate() callback tries to return 2400000000, but it does not fit in a signed 32-bit-wide variable and it is treated as -1894967296, which is an error. In order to handle clock frequency safely, shall we use "long long" instead? (It is guaranteed to have 64-bit width) -- Best Regards Masahiro Yamada
