2018-12-13ARM: omap2: avoid section mismatch warningArnd Bergmann1-1/+1
WARNING: vmlinux.o(.text+0x27530): Section mismatch in reference from the function am43xx_suspend_init() to the function .init.text:am43xx_map_scu() The function am43xx_suspend_init() references the function __init am43xx_map_scu(). This is often because am43xx_suspend_init lacks a __init annotation or the annotation of am43xx_map_scu is wrong.

2018-07-10ARM: OMAP2+: sleep33/43xx: Add RTC-Mode supportKeerthy1-0/+10
Add support for RTC mode to low level suspend code. This includes providing the rtc base address for the assembly code to configuring the PMIC_PWR_EN line late in suspend to enter RTC+DDR mode. Note: This patch also fold in left out space parameter for am33xx_emif_sram_table and am43xx_emif_sram_table Signed-off-by: Dave Gerlach <d-gerlach@ti.com> Signed-off-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2018-07-10ARM: OMAP2+: sleep33/43xx: Make sleep actions configurableDave Gerlach1-4/+6
Add an argument to the sleep33xx and sleep43xx code to allow us to set flags to determine which portions of the code get called in order to use the same code for multiple power saving modes. This patch allows us to decide whether or not we flush and disable caches, save EMIF context, put the memory into self refresh and disable the EMIF, and/or invoke the wkup_m3 when entering into WFI.

2018-04-30ARM: OMAP2+: Initialize SoC PM laterTony Lindgren1-1/+3
There's no need to probe devices until at module_init time and we currently have at least PM trying to use I2C for PMICs early on. As only a part of the SoC init_early is SoC specific, we only need to call the SoC specific PM init function. And we can modify omap2_common_pm_late_init() so it becomes a late_initcall(). Note that this changes am335x to call omap2_clk_enable_autoidle_all() that seems to be missing currently.

2018-02-27ARM: OMAP2+: pm33xx-core: Add platform code needed for PMDave Gerlach1-0/+189
Most of the PM code needed for am335x and am437x can be moved into a module under drivers but some core code must remain in mach-omap2 at the moment. This includes some internal clockdomain APIs and low-level ARM APIs which are also not exported for use by modules. Implement a few functions that handle these low-level platform operations can be passed to the pm33xx module through the use of platform data. In addition to this, to be able to share data structures between C and the sleep33xx and sleep43xx assembly code, we can automatically generate all of the C struct member offsets and sizes as macros by processing pm-asm-offsets.c into assembly code and then extracting the relevant data as is done for the generated platform asm-offsets.h files. Finally, add amx3_common_pm_init to create a dummy platform_device for pm33xx so that our soon to be introduced pm33xx module can probe on am335x and am437x platforms to enable basic suspend to mem and standby support.
