The sysfs control /sys/power/clocks_off_while_idle only affects the UART clocks. And these can now be controlled with a UART specific timeout sysfs control. The system default behavior is to have the equivalent of clocks_off_while_idle == 1 and a UART inactivity timeout of 5 seconds. Now one can use /sys/devices/platform/serial8250.<uart>/sleep_timeout to set the inactivity timer for the UART in seconds. Setting this value to zero disables the timout and is the equivalent of doing an echo 0 > /sys/power/clocks_off_while_idle Kevin Hilman (2): OMAP: PM: UART: zero sleep_timeout will disable timeout feature OMAP2/3: PM: remove /sys/power/clocks_off_while_idle arch/arm/mach-omap2/pm.c | 12 ------------ arch/arm/mach-omap2/pm.h | 1 - arch/arm/mach-omap2/serial.c | 16 +++++++++++----- 3 files changed, 11 insertions(+), 18 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
