From: "Tony Lindgren" <tony@atomide.com> The following changes since commit 9e98c678c2d6ae3a17cb2de55d17f69dddaa231b: Linux 5.1-rc1 (2019-03-17 14:22:26 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap tags/omap-for-v5.2/am4-pm-v2-signed for you to fetch changes up to 35667d812c38a219ea2dc6f23d33db50de57099e: Merge branch 'omap-for-v5.2/am4-ddr3' into omap-for-v5.2/am4-pm-v2 (2019-04-10 09:06:01 -0700) ---------------------------------------------------------------- PM changes for am335x and am437x This series adds support for am437x RTC-only mode in suspend. In the RTC-only mode suspend, everything is shut down except the RTC. This makes the power consumption very low for suspend mode. To support RTC-only mode, we need to export omap_rtc_power_off_program() from the rtc driver and improve PM code to save and restore the wkup domain context. As RTC-only mode depends on the device being wired properly for things like memory, we need to also check for the machine type before we allow it. We also need to run DDR3 hardware leveling on resume. Note that there is a trivial merge conflict between the RTC branch and these changes where the RTC branch makes tm2bcd() a void function and the error handling parts can be just dropped. ---------------------------------------------------------------- Dave Gerlach (2): memory: ti-emif-sram: Add ti_emif_run_hw_leveling for DDR3 hardware leveling ARM: OMAP2+: sleep43xx: Run EMIF HW leveling on resume path Keerthy (4): rtc: OMAP: Add support for rtc-only mode ARM: OMAP2+: pm33xx: Add support for rtc+ddr in self refresh mode soc: ti: pm33xx: Move the am33xx_push_sram_idle to the top soc: ti: pm33xx: AM437X: Add rtc_only with ddr in self-refresh support Tony Lindgren (1): Merge branch 'omap-for-v5.2/am4-ddr3' into omap-for-v5.2/am4-pm-v2 arch/arm/mach-omap2/pm33xx-core.c | 76 +++++++++- arch/arm/mach-omap2/sleep43xx.S | 3 + drivers/memory/emif.h | 4 + drivers/memory/ti-emif-pm.c | 3 + drivers/memory/ti-emif-sram-pm.S | 41 ++++++ drivers/rtc/rtc-omap.c | 51 +++++-- drivers/soc/ti/Kconfig | 5 +- drivers/soc/ti/pm33xx.c | 273 ++++++++++++++++++++++++++++------- include/linux/platform_data/pm33xx.h | 5 + include/linux/rtc/rtc-omap.h | 7 + include/linux/ti-emif-sram.h | 3 + 11 files changed, 409 insertions(+), 62 deletions(-) create mode 100644 include/linux/rtc/rtc-omap.h
