| | | | | | | | | | | | | With commit df6c2ec872a6 ("ARM: OMAP2+: Drop legacy remaining legacy platform data for am4") we moved am4 to boot with simple-pm-bus using genpd and devicetree based data. But I forgot to test am4 only build that still has few references to the old platform data left, and cause undefined reference errors with omap_hwmod_set_postsetup_state and omap_hwmod_for_each.

| | | | | | | | | | | | | | | | | | | | | | | | | Recent omap changes added runtime checks to use omap_smccc_smc() when optee is configured in dts. As the omap-secure code can be built for ARMv6 only without ARMv7 and use custom smc calls, we now get a build error: omap-secure.c:(.text+0x94): undefined reference to `__arm_smccc_smc' As there secure calls are not used for ARMv6, we should not build secure-common, and not call omap_secure_init() for omap2.

* ARM: OMAP2+: Initialize SoC PM laterTony Lindgren2018-04-301-58/+9
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | Looks like these functions don't do anything in the mainline kernel so we can just drop it. Note that we must now also remove ir-rx51 pdata as it relies on the dummy platform data that does not do anything. And ir-rx51 is calling a pdata callback that doesn't do anything without checking if it exists first. For configuring device specific minimal latencies, the interface to use is pm_qos_add_request(). For an example, see what was done in commit 9834ffd1ecc3 ("ASoC: omap-mcbsp: Add PM QoS support for McBSP to prevent glitches"). I've added some comments to ir-rx51 so people using it can add pm_qos support and test it.

* ARM: OMAP2+: pm33xx-core: Add platform code needed for PMDave Gerlach2018-02-271-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ARM: OMAP2+: Register SoC device attributes from machine .init()Laurent Pinchart2017-08-151-1/+0
| | | | | | | | | | | | | | | | | SoC device attributes are registered with a call to soc_device_register() from the machine .init_late() operation, which is called from the late initcall, after all drivers built-in drivers have been probed. This results in the impossibility for drivers to use SoC device matching in their probe function. The omap_soc_device_init() function is safe to call from the machine .init() operation, as all data it depends on is initialized from the .init_early() operation. Move SoC device attribute registration to machine .init() like on all other ARM platforms.

* ARM: OMAP4+: Prevent CPU1 related hang with kexecTony Lindgren2016-06-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | Kexec booted kernels on omap4 will hang early during the boot if the booted kernel is different version from the previous kernel. This is because the previous kernel may have configured low-power mode using CPU1_WAKEUP_NS_PA_ADDR. In that case it points to the previous kernel's omap4_secondary_startup(), and CPU1 can be in low power mode from the previous kernel. When the new kernel configures the CPU1 clockdomain, CPU1 can wake from low power state prematurely during omap44xx_clockdomains_init() running random code. Let's fix the issue by configuring CPU1_WAKEUP_NS_PA_ADDR before we call omap44xx_clockdomains_init(). Note that this is very early during the init, and we will do proper CPU1 reset during SMP init a bit later on in omap4_smp_prepare_cpus(). And we need to do this when SMP is not enabled as the previous kernel may have had it enabled.

This allows us to configure CPU1 for kexec in case the previous kernel has put CPU1 in low power mode. Note that this should not prevent moving other SAR RAM code to live under drivers. However for kexec, we will need this very early. Acked-by: Santosh Shilimkar <ssantosh@kernel.org> Tested-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | DRA7 uses OMAP5 IO table at the moment. This is purely spurious since the OMAP5 and DRA7 register maps are different in many aspects. AM57xx/DRA7 TRM Reference: http://www.ti.com/lit/ug/spruhz6/spruhz6.pdf NOTE: Most of the drivers are already doing ioremap, so, there should'nt be any functional improvement involved here, other than making the initial iotable more accurate.

| | | | | | | | | | | | | | | | | | | | There is no need to provide the control module base address through a low-level API from the low-level IO init, as this information is available through DT. This patch adds a new API to initialize the control module though, but mostly makes the old API obsolete. The old API can be completely removed once OMAP3 is made DT only.
