Hi, This patch set contains all workarounds that are needed to get omap3 to retention. Also patch from Tero Kristo to get PM to work if using serial console is included in this set. Basically all patches in this set should be reverted one by one as correct fixes are implemented and applied. This patch set superseeds earlier version sent 2008-06-17 7:28:35. To get Omap into retention, this patch set still depends on: 1. ARCH: OMAP: MUSB: Do not block sleep (Felipe Balbi) 2. ARM: OMAP: SmartReflex driver: enable in omap_3430sdp_defconfig (Kalle Jokiniemi) 3. PRCM: 34XX: Fix wrong shift value used in dpll4_m4x2_ck enable bit 4. Patch which removes control of usbhost_sar_fck from clock tree (Paul Walmsley will send this soon) Test: 1. Apply dependency patches and workaround set on top of them 2. Enable disabling/enabling of gpio2-6 and uart clocks on idle: $ echo 1 > /sys/power/clocks_off_while_idle 3. Try out static suspend: $ echo mem > /sys/power/state Wake up from suspend by entering character to serial console. This should print out: "Successfully put all powerdomains to target state" 4. Try out dynamic sleep: $ echo 1 > /sys/power/sleep_while_idle On Omap3430 SDP board VCORE_EN led can be used as an indicator. If it starts to blink after a while then Omap enters retention on idle. To make this work also display needs to be blanked. -- Jouni Högander -- 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
