| * | | ARM: OMAP2+: Add more functions to pwm pdata for ir-rx51Tony Lindgren2016-04-28
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before we start removing omap3 legacy booting support, let's make n900 DT booting behave the same way for ir-rx51 as the legacy booting does. For now, we need to pass pdata to the ir-rx51 driver. This means that the n900 tree can move to using DT based booting without having to carry all the legacy platform data with it when it gets dropped from the mainline tree. Note that the ir-rx51 driver is currently disabled because of the dependency to !ARCH_MULTIPLATFORM. This will get sorted out later with the help of drivers/pwm/pwm-omap-dmtimer.c. But first we need to add chained IRQ support to dmtimer code to avoid introducing new custom frameworks. So let's just pass the necessary dmtimer functions to ir-rx51 so we can get it working in the following patch.

These seem to be caused by the following: - OMAP3 Advisory 1.62 "MPU Cannot Exit from Standby" says we need to disable intc autoidle before WFI - DM3730 Advisory 1.106 "MPU Leaves MSTANDBY State Before IDLEREQ of Interrupt Controller is Released" says we need to wait before accessing intc omap3_intc_resume_idle restores the intc autoidle for all resume paths, however in the resume path from off mode only it is also being restored by omap_intc_restore_context before this call to omap3_intc_resume_idle happens. The second restore of the intc autoidle in this path is what appears to be causing the external abort so for the off mode resume path let's rely on omap_intc_restore_context to restore intc autoidle, and for all other paths let omap3_intc_resume_idle handle it as it is now.

This can result in missed timer interrupts. Workaround: In order for TIMER5/6/7/8 interrupts to be propagated and serviced correctly the CD_IPU domain should be set to SW_WKUP mode (CM_IPU_CLKSTCTRL[0:1]CLKTRCTRL=0x2:SW_WKUP). The above workaround is achieved by switching the IPU clockdomain flags from HWSUP_SWSUP to SWSUP only.

It seems suspend worked earlier as things were only partially initialized, while now we initialize things properly for dra7. Note that the "ARM: OMAP: Catch callers of revision information prior to it being populated" had to be reverted as it caused bogus warnings for other SoCs because omap initcalls bail out based on revision being set to 0 for other SoCs. These initcalls will mostly just disappear when we drop support for omap3 legacy booting.

Without doing this, soc_is_dra7xx() will fail and as a result, omap4_pm_init_early never initializes the dra7 erratum for CPU power state. This causes the suspend path to fail on DRA7 devices.

This means that the hwmod code can not directly control the TPCC enable/disable status.

This handler is required to deassert PCIe hardreset lines after they have been asserted. This enables the PCIe driver to access registers after PCIeSS has been runtime enabled without having to deassert hardreset lines itself. With this patch applied, used lspci to make sure connected PCIe device enumerates on DRA74x and DRA72x EVMs. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Reported-by: Richard Cochran <richardcochran@gmail.com> Tested-by: Kishon Vijay Abraham I <kishon@ti.com> Cc: Suman Anna <s-anna@ti.com> Cc: Dave Gerlach <d-gerlach@ti.com> Cc: Tony Lindgren <tony@atomide.com> Cc: Bjorn Helgaas <bhelgaas@google.com> Cc: Russell King <linux@arm.linux.org.uk> Signed-off-by: Paul Walmsley <paul@pwsan.com>

The RTC module is physically present on the AM438x SoC used on AM43X-EPOS-EVM, but it is permanently disabled. A secure RTC is used instead on these devices, where needed. Hence adding it selectively using a separate list to get RTC Module functional on the other am43x SoCs used on am437x-gp-evm and am437x-sk-evm.

Let's let the interconnect disable the device on BUS_NOTIFY_UNBOUND_DRIVER. Otherwise omap_device will produce and error on the following module reload. This can be easily tested with something like: # modprobe omap_hsmmc # echo on > /sys/devices/platform/68000000.ocp/4809c000.mmc/power/control # rmmod omap_hsmmc # modprobe omap_hsmmc Cc: Alan Stern <stern@rowland.harvard.edu> Cc: Nishanth Menon <nm@ti.com> Cc: Rafael J.

On the following device driver probe, hardware state is different from the PM runtime state causing omap_device to produce the following error: omap_device_enable() called from invalid state 1 And with omap_device and omap hardware being picky for PM, this will block any deeper idle states in hardware. Let's add a proper error message so driver writers can easily fix their drivers for PM. In general, the solution is to fix the drivers to follow the PM runtime documentation: 1. For sections of code that needs the device disabled, use pm_runtime_put_sync_suspend() if pm_runtime_set_autosuspend() has been set. 2. For driver exit code, use pm_runtime_dont_use_autosuspend() before pm_runtime_put_sync() if pm_runtime_use_autosuspend() has been set. Let's not return with 0 from _od_runtime_resume() as that will eventually lead into new drivers with broken PM runtime that will block deeper idle states on omaps.

Fix error "Unable to handle kernel paging request at virtual address c012396c" in wait_dll_lock_timed if CONFIG_DEBUG_RODATA is selected. As these counters are for debugging only and unused, we can just remove them.

| * | | | ARM: OMAP2+: Remove legacy mailbox device instantiationSuman Anna2016-01-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The legacy-style mailbox device creation is supported currently only for OMAP3, as all other SoCs are DT-boot only. Even on this SoC, there are no client drivers that utilize these mailbox devices. So, clean up the legacy-style mailbox device instantiation logic. The mailbox devices are already present and supported for the DT boot on OMAP3. Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

| |_|/ / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this booting t410 can fail randomly with no output depending on the .config options chosen. Enabling debug_ll causes the problem to go away. I narrowed this down to USB by disabling one module at a time.
