Boot on all OMAP2+ devices is broken with earlycon enabled as discussed here [1] There were 2 issues which were rootcaused 1. Issue caused due to hwmod doing a reset of console uart while earlycon was using it (seen only on am335x devices) 2. omap serial causing a NULL context restore with context loss count missing. This patch set attempts to fix both the issues and is one of the different approaches discussed [1] on how to fix these issues. Boot tested on omap4 panda es with and without earlycon (DT boot) Boot tested on am335x bone black with and without earlycon (DT boot) Boot tested on OMAP3 beagle XM with and without earlycon (non-DT boot) [1] http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg91662.html Grygorii Strashko (1): serial: omap: enable PM runtime only when its fully configured Rajendra Nayak (3): ARM: OMAP2+: hwmod: Fix a crash in _setup_reset() with DEBUG_LL ARM: OMAP2+: Avoid idling memory controllers with no drivers ARM: OMAP2+: Sync hwmod state with the pm_runtime and omap_device state arch/arm/mach-omap2/omap_device.c | 18 ++++++++ arch/arm/mach-omap2/omap_hwmod.h | 48 ++++++++++++++++++++ arch/arm/mach-omap2/omap_hwmod_2xxx_ipblock_data.c | 6 +-- arch/arm/mach-omap2/omap_hwmod_33xx_data.c | 2 +- arch/arm/mach-omap2/omap_hwmod_3xxx_data.c | 9 ++-- arch/arm/mach-omap2/omap_hwmod_44xx_data.c | 5 +- arch/arm/mach-omap2/omap_hwmod_54xx_data.c | 3 +- arch/arm/mach-omap2/serial.c | 11 ----- drivers/tty/serial/omap-serial.c | 3 +- 9 files changed, 81 insertions(+), 24 deletions(-) -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
