drivers/cpufreq/pcc-cpufreq.c: avoid NULL pointer dereference

2011-09-15T01:09:38Z

per_cpu(processors, n) can be NULL, resulting in: Loading CPUFreq modules[ 437.661360] BUG: unable to handle kernel NULL pointer dereference at (null) IP: [] pcc_cpufreq_cpu_init+0x74/0x220 [pcc_cpufreq] It's better to avoid the oops by failing the driver, and allowing the system to boot.

[CPUFREQ] S3C6410: Add some lower frequencies for 800MHz base clock operation

2011-07-13T22:29:59Z

By extension from the 667MHz based clocks currently supported add 100MHz and 200MHz operating points. Due to a lack of documentation these have not been confirmed as supported but by extension from the existing frequencies they should be OK, and I've given them quite a bit of runtime testing. The major risk is synchronization with the non-ARM clocks but as we can't currently scale the ARM PLL the risk should be relatively low.

[CPUFREQ] S5PV210: Adjust udelay prior to voltage scaling down

2011-07-13T22:29:58Z

Voltage scaling accesses the MAX8998 regulators over bit-banged I2C with lots of udelays. In the case of decreasing CPU speed, the number of loops per us for udelay needs to be adjusted prior to decreasing voltage to avoid delaying for up to 10X too long.
