Use irq_set_handler_locked() as it avoids a redundant lookup of the irq descriptor. Search and replacement was done with coccinelle.

Chained irq handlers usually set up handler data as well. We now have a function to set both under irq_desc->lock. Replace the two calls with one. Search and conversion was done with coccinelle. Reported-by:

Add the pinctrl driver for the Qualcomm Technologies QDF2xxx ARM64 SoCs, which uses the Qualcomm Technologies TLMM pinctrl/gpio device. This driver is probed via ACPI and uses the pinctrl-msm.c backend driver. This driver is intended to be used only an ACPI-enabled system. As such, UEFI will handle all pin control configuration, so this driver does not provide pin control functions. It is effectively a GPIO-only driver. Signed-off-by:

The "function" of the MPP driver was inherited from the GPIO driver, but the differences between the two hardware blocks makes both the driver and the device tree binding to be awkward. Instead of overloading the "normal" function with various modes this patch transposes the pinmux function to represent the three operating modes of the MPP (digital, analog and current sink). The properties of pin pairing and DTEST routing is moved to separate properties. Signed-off-by:

When the MPP is configured for analog output the output level is selected by the AOUT_CTL register, this patch makes it possible to control this. Signed-off-by:

The function pinconf_dbg_config_print() only prints the configuration of the 1st pin config in an array of pin configurations. Fix this so that all pin configurations in the array are displayed. There are a few places in the code where the pin configs are displayed and so add a helper function to display the pin configs to simplify the code. Signed-off-by:

Assign pm_power_off() if we have the PS_HOLD functionality so that we can properly shutdown the SoC. Otherwise, shutdown won't do anything besides put the CPU into a tight loop. Unfortunately, we have to use a singleton here because pm_power_off() doesn't take any arguments. Fortunately there's only one instance of the pinctrl device on a running system so this isn't a problem. Cc: Pramod Gurav <pramod.gurav@smartplayin.com> Signed-off-by:

Since the removal of the r8a7740 legacy SoC code in commit 44d88c75 ("ARM: shmobile: Remove legacy SoC code for R-Mobile A1"), r8a7740 is only supported in generic DT-only ARM multi-platform builds. The driver doesn't need to match platform devices by name anymore, hence remove the corresponding platform_device_id entry. Signed-off-by:

If the pin function controller (which can be a GPIO controller) is instantiated before the interrupt controllers, due to the ordering in the DTS, the irq domains for the interrupt controllers referenced by its "interrupts-extended" property cannot be found yet: irq: no irq domain found for /interrupt-controller@e61c0000 ! As the sh-pfc driver accesses the platform device's resources directly, it cannot find the (optional) IRQ resources, and thinks no interrupts are available. This may lead to failures later, when GPIOs are used as interupts: gpio-keys keyboard: Unable to claim irq 0; error -22 gpio-keys: probe of keyboard failed with error -22 To fix this, add support for deferred probing to sh-pfc, by converting the driver from direct platform device resource access to using the platform_get_resource() and platform_get_irq() helpers. Note that while this fixes the root cause worked around by commit e4ba0a9b ("ARM: shmobile: r8a73a4: Move pfc node to work around probe ordering bug"), I strongly recommend against reverting the workaround now, as this would lead to lots of probe deferrals in drivers relying on pinctrl. This may be reconsidered once the DT code starts taking into account phandle dependencies during device instantation. Signed-off-by: -

Checkpatch.pl complains about these: WARNING: Possible unnecessary 'out of memory' message The messages use a little extra RAM and they add a few extra lines of code. We're probably never going to hit these out of memory situations but if we did then kmalloc() has pretty good error messages built-in. Signed-off-by:

We were allocating enough space because sizeof("-grp") and sizeof("-mux") are both equal to 5 but in the snprintf() we only allowed for 4 characters so the last 'p' and 'x' characters were truncated. The allocate and sprintf can be done in one step with the kasprintf(). Signed-off-by: -

There's currently no way to re-enable a mpp block once you've entered a state that disables the state, this patch makes it possible to leave the bias-high-impedance state. Also read the enable state from the hardware on probe. With this in place the is_enabled variable is accurately tracking the state of the hardware and we can use that for the debug output as well.
