The (trivial) patch is already prepared to enable BOOST at cpufreq for Exynos4412. I will post it for v6. Sorry for not posting it earlier.
The whole patch is as follow:
static struct clk *cpu_clk; static struct clk *mout_core; static struct clk *sclk_mpll; static struct clk *mout_apll;
static unsigned int exynos4x12_volt_table[] = { 1350000, 1287500, 1250000, 1187500, 1137500, 1087500, 1037500, 1000000, 987500, 975000, 950000, 925000, 900000, 900000 }; static struct cpufreq_frequency_table exynos4x12_freq_table[] = { - {L0, CPUFREQ_ENTRY_INVALID}, + {CPUFREQ_BOOST_FREQ, 1500 * 1000}, {L1, 1400 * 1000}, {L2, 1300 * 1000}, {L3, 1200 * 1000}, {L4, 1100 * 1000}, {L5, 1000 * 1000}, {L6, 900 * 1000}, {L7, 800 * 1000}, {L8, 700 * 1000}, {L9, 600 * 1000}, {L10, 500 * 1000}, {L11, 400 * 1000}, {L12, 300 * 1000},
