[PATCH 2/4] PM: Workaround for taking care of gpio clocks

by leaving icks active. PER domain still enters retention together with MPU. When this happens IOPAD wake up mechanism is used for gpios. Signed-off-by: Jouni Hogander <[EMAIL PROTECTED]> --- arch/arm/mach-omap2/pm34xx.c | 54 +- 1 files chang

[PATCH 1/4] 34XX: PM: Workaround to check wether any fck is active before entering sleep

This workaround shouldn't be needed when all drivers are configuring their sysconfig registers properly and using their clocks properly. Signed-off-by: Jouni Hogander <[EMAIL PROTECTED]> --- arch/arm/mach-omap2/pm34xx.c | 37 + 1 files changed, 37

[PATCH 3/4] Added sleep support to UART

x27;t enter retention. Also moved code from pm-debug.c to serial.c, and made pm24xx.c use this new implementation. Signed-off-by: Jouni Hogander <[EMAIL PROTECTED]> --- arch/arm/mach-omap2/pm-debug.c | 132 -- arch/arm/mach-omap2/pm.h |7

[PATCH 4/4] 34XX: PM: Workaround to enable autoidle for clocks and plls

From: ext Jouni Hogander <[EMAIL PROTECTED]> This workaround enables autoidle for interface clocks and plls. Also automatic control of external oscillator through sys_clkreq is enabled. Proper fix to this is to generalize omap3_dpll_allow_idle, omap3_dpll_deny_idle, omap3_dpll_autoidle_re

[PATCH] OMAP: DISPC: Enable dispc wake up capability

Without wakeup enable omap doesn't wake up on dispc interrupts. This causes problems in a case where mpu is in sleep state and dispc interrupt fires. Signed-off-by: Jouni Hogander <[EMAIL PROTECTED]> --- drivers/video/omap/dispc.c |4 ++-- 1 files changed, 2 insertions(+),
