2016-07-04ARM: OMAP2+: clockdomain: add usecounting support to autoidle APIsTero Kristo7-50/+47
The previous implementation was racy in many locations, where the current status of the clockdomain was read out, some operations were executed, and the previous status info was used afterwards to decide next state for the clockdomain. Instead, fix the implementation of the allow_idle / deny_idle APIs to properly have usecounting support. This allows clean handling internally within the clockdomain core, and simplifies the usage also within hwmod.

2016-06-22ARM: OMAP4+: Reset CPU1 properly for kexecTony Lindgren1-26/+70
We need to reset CPU1 properly for kexec when booting different kernel versions. Otherwise CPU1 will attempt to boot the the previous kernel's start_secondary(). Note that the restctrl register is different from the low-power mode wakeup register CPU1_WAKEUP_NS_PA_ADDR. We need to configure both. Let's fix the issue by defining SoC specific data to initialize things in a more generic way. And let's also standardize omap-smp.c to use soc_is instead of cpu_is while at it.

2016-06-22ARM: OMAP4+: Prevent CPU1 related hang with kexecTony Lindgren4-8/+32
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.

Prepare things for making kexec work on SMP omap variants by initializing SARM RAM base early. 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.

A few platforms are currently missing clocksource_probe() completely in their time_init functionality. On OMAP3430 for example, this is causing cpuidle to be pretty much dead, as the counter32k is not going to be registered and instead a gptimer is used as a clocksource.

As per the latest revision F of public TRM for DRA7/AM57xx SoCs SPRUHZ6F[1] (April 2016), with the exception of MPU power domain (and CPUx sub power domains), all other power domains can either operate in "ON" mode OR in some cases, "OFF" mode. For these power states, the logic retention state is basically ignored by PRCM and does not require to be programmed.

2016-06-10ARM: OMAP3: pdata-quirks: Add support for McBSP2/3 sidetone handlingPeter Ujfalusi2-0/+27
McBSP2/3 module's sidetone module operates using the module's ICLK clock. When the Sidetone is in use the interface clock of the module must not idle. To prevent the iclk idling the driver expects to have pdata callback to call. With this patch the callback is going to be set up for DT boot also.

2016-06-10ARM: OMAP3: McBSP: New callback for McBSP2/3 ICLK idle configurationPeter Ujfalusi1-0/+12
McBSP2/3 module's sidetone module operates using the module's ICLK clock. When the Sidetone is in use the interface clock of the module must not idle. The new callback expects to receive the *clk of the module's ick and not the id number of the McBSP. This will allow us more cleanups and going to simplify the ICLK handling.

2016-06-10ARM: OMAP3: hwmod data: Fix McBSP2/3 sidetone dataPeter Ujfalusi1-20/+4
The McBSPLP's sidetone main clock is the McBSPLP's ICLK, not FCLK as the sidetone only receives the ICLK from the main McBSP module. Since the McBSP and sidetone is using the very same clock from PRCM level the sidetone must not have the prcm section to check the clock status since the sidetone is only used when McBSP is already configured. If two separate hwmods looking at the same bit and they would use pm_runtime in nested way (as it must happen with McBSP and it's ST module) the hwmod would warn, because the idlest will not match what it is expected after enable/disable of the clocks.

2016-06-10ARM: AM335x/AM437x: hwmod: Remove eQEP, ePWM and eCAP hwmod entriesFranklin S Cooper Jr5-229/+0
Devices that utilize the OCP registers and/or PRCM registers and register bit fields should be modeled using hwmod. Since eQEP, ePWM and eCAP don't fall under this category, remove their hwmod entries. Instead these clocks simply use the clock that is passed through by its parent PWMSS. Therefore, PWMSS handles the clock for itself and its subdevices.

Enable Erratum 430973 similar to commit 5c86c5339c56 ("ARM: omap2plus_defconfig: Enable ARM erratum 430973 for omap3") - Since multiple defconfigs can exist from various points of view (multi_v7, omap2plus etc.. it is always better to enable the erratum from the Kconfig selection point of view so that downstream kernels dont have to rediscover this all over again.

2016-06-03ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIBLinus Walleij1-1/+1
This replaces: - "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can now be selected directly. - "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB is now selectable by everyone, so we need not declare our intent to select it. When ordering the symbols the following rationale was used: if the selects were in alphabetical order, I moved select GPIOLIB to be in alphabetical order, but if the selects were not maintained in alphabetical order, I just replaced "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".
