It is true that Maximum frequency had been indicated as higher but current value is 210MHz if VDD core is @ 1.8V (for industrial temperature range). > Signed-off-by: Jiri Prchal <jiri.prchal@aksignal.cz> > --- > arch/arm/mach-at91/clock.c | 2 +- > 1 files changed, 1 insertions(+), 1 deletions(-) > > diff --git a/arch/arm/mach-at91/clock.c b/arch/arm/mach-at91/clock.c > index de2ec6b..e004308 100644 > --- a/arch/arm/mach-at91/clock.c > +++ b/arch/arm/mach-at91/clock.c > @@ -707,7 +707,7 @@ static int __init at91_pmc_init(unsigned long main_clock) > if (plla.rate_hz > 800000000) > pll_overclock = true; > } else { > - if (plla.rate_hz > 209000000) > + if (plla.rate_hz > 219000000) Well, I rework this patch using 210 MHz as stated in datasheet. We shall keep this 209 MHz test because at91rm9200 is still using this value. Moreover, I add a new category for 240 MHz. > pll_overclock = true; > } > if (pll_overclock) Thanks, best regards,

This patch fix false warning "PLLA overclocked". Maximum frequency for sam9260 is 210MHz as stated in atmel's datasheet. Originally there was plus 4.5%, so I add this 4.5% to new value too.
