* ARM: OMAP2+: Fix omap_device for module reload on PM runtime forbidTony Lindgren2016-02-121-0/+10
| | | | | | | | | | | | | | | | | | | | | | | If a driver PM runtime is disabled via sysfs, and the module is unloaded, PM runtime can't do anything to disable the device. 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.

* ARM: OMAP2+: Improve omap_device error for driver writersTony Lindgren2016-02-121-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers using pm_runtime_use_autosuspend() may not get disabled after -EPROBE_DEFER. 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.

* ARM: DTS: am57xx-beagle-x15: Select SYS_CLK2 for audio clocksPeter Ujfalusi2016-02-111-0/+4
| | | | | | | | | | | The tlv320aic3104 codec's master clock is coming from the SoC's CLKOUT2. Select the SYS_CLK2 (via divider) as parent clock for CLKOUT2 and select the same clock (SYS_CLK2) for McASP3 AHCLKX clock as well. SYS_CLK2 is sourced from an external oscillator running 22.5792MHz and it is coming in to the SoC via the X1_OSC1.

| | | | | | | | | | | | | | | Commit 3efda00129bd ("ARM: dts: am335x: replace gpio-key,wakeup with wakeup-source property") replaces all the legacy "gpio-key,wakeup" with the unified "wakeup-source" property to prevent any further copy-paste duplication. However couple of use of these legacy property sneaked in during the merge window. This patch replaces them too.

Most of these are fixes and tweaks to board support (DT bugfixes, etc). I've also picked up a couple of small cleanups that seemed innocent enough that there was little reason to wait (const/ __initconst and Kconfig deps). Quite a bit of the changes on OMAP were due to fixes to no longer write to rodata from assembly when ARM_KERNMEM_PERMS was enabled, but there were also other fixes. Kirkwood had a bunch of gpio fixes for some boards. OMAP had RTC fixes on OMAP5, and Nomadik had changes to MMC parameters in DT.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DTSI file for the Nomadik does not properly specify how the PL180 levelshifter is connected: the Nomadik actually needs all the five st,sig-dir-* flags set to properly control all lines out. Further this board supports full power cycling of the card, and since this variant has no hardware clock gating, it needs a ridiculously low frequency setting to keep up with the ever overflowing FIFO. The pin configuration set-up is a bit of a mystery, because of course these pins are a mix of inputs and outputs. However the reference implementation sets all pins to "output" with unspecified initial value, so let's do that here as well.

The sys_nirq pin is used for interrupts, and msecure pin is used for enabling writes to some PMIC registers. Without these pins configured properly things can fail in mysterious ways. For example, we can't update the RTC registers on palmas PMIC unless the msecure pin is configured. And this is probably the reason why we had RTC missing from the omap5 dts file. According to "OMAP5430 ES2.0 Data Manual [Public] VErsion A (Rev. F)" swps052f.pdf, mux mode 1 is for sys_drm_msecure so in theory there's should be no need to configure it as a GPIO pin. However, it seems there are some reliability issues using the msecure mux mode. And the TI trees configure the msecure pin as GPIO out high instead. As the PMIC only cares that the msecure line is high to allow access to the RTC registers, let's use a GPIO hog as suggested by Nishanth Menon <nm@ti.com>. Also the use of the internal pull was considered but supposedly that may not be capable of keeping the line high in a noisy environment. If we ever see high security omap5 products in the mainline tree, those need to skip the msecure pin muxing and ignore setting the GPIO hog. Chances are the related pin mux registers are locked in that case and the msecure pin is managed by whatever software may be running in the ARM TrustZone. Who knows what the original intention of the msecure pin was. Maybe it was supposed to prevent the system time to be set back for some game demo modes to time out? Anyways, it seems that later PMICs like tps659037 have recycled this pin for "powerhold" and devices like beagle-x15 do not need changes to the msecure pin configuration. To avoid further confusion with TWL variant PMICs, beagle-x15 does not have a back-up battery for RTC palmas. Instead the mcp79410 RTC is used with rtc-ds1307 driver. There is a "powerhold" jumper j5 holes near the palmas PMIC, and shorting it seems to power up beagle-x15 automatically. It is unknown if it also has other side effects to the beagle-x15 power up sequence. Cc: stable@vger.kernel.org # v4.4 Signed-off-by: Tony Lindgren <tony@atomide.com>
