* spmi: pmic-arb: validate type when mapping IRQBrian Masney2019-01-241-7/+14
| | | | | | | | | | | qpnpint_irq_domain_map did not validate the IRQ type and this can cause IRQs to not work as expected if an unsupported type (such as IRQ_TYPE_NONE) is passed in. Now that spmi-gpio is a hierarchical IRQ controller, and all device tree bindings have been updated, add additional validation to the type field.

* qcom: spmi-gpio: add support for hierarchical IRQ chipBrian Masney2019-01-241-10/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | spmi-gpio did not have any irqchip support so consumers of this in device tree would need to call gpio[d]_to_irq() in order to get the proper IRQ on the underlying PMIC. IRQ chips in device tree should be usable from the start without the consumer having to make an additional call to get the proper IRQ on the parent. This patch adds hierarchical IRQ chip support to the spmi-gpio code to correct this issue. Driver was tested using the volume buttons (via gpio-keys) on the LG Nexus 5 (hammerhead) phone with the following two configurations. volume-up { interrupts-extended = <&pm8941_gpios 2 IRQ_TYPE_EDGE_BOTH>; ... }; volume-up { gpios = <&pm8941_gpios 2 GPIO_ACTIVE_LOW>; ... }; Both configurations now show that spmi-gpio is the IRQ domain and that the IRQ is setup in a hierarchy. $ grep volume_up /proc/interrupts 72: 6 0 spmi-gpio 1 Edge volume_up $ cat /sys/kernel/debug/irq/irqs/72 handler: handle_edge_irq device: (null) status: 0x00000403 _IRQ_NOPROBE istate: 0x00000000 ddepth: 0 wdepth: 0 dstate: 0x02400203 IRQ_TYPE_EDGE_RISING IRQ_TYPE_EDGE_FALLING IRQD_ACTIVATED IRQD_IRQ_STARTED node: 0 affinity: 0-3 effectiv: domain: :soc:spmi@fc4cf000:pm8941@0:gpios@c000 hwirq: 0x1 chip: spmi-gpio flags: 0x4 IRQCHIP_MASK_ON_SUSPEND parent: domain: :soc:spmi@fc4cf000 hwirq: 0xc100057 chip: pmic_arb flags: 0x4 IRQCHIP_MASK_ON_SUSPEND Signed-off-by: Brian Masney <masneyb@onstation.org> Reviewed-by: Stephen Boyd <sboyd@kernel.org> Reviewed-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* spmi: pmic-arb: disassociate old virq if hwirq mapping already existsBrian Masney2019-01-241-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Check to see if the hwirq is already associated with another virq on this IRQ domain. If so, then disassociate it before associating the hwirq with the new virq. This is a temporary hack that is needed in order to not break git bisect for existing boards. The next patch in this series converts spmi-gpio to be a hierarchical IRQ chip, then there are several patches to update all of the device tree files, and finally this patch will be reverted within the same patch series. IRQs for spmi-gpio are all initially setup without an IRQ hierarchy on pmic-arb when mfd/qcom-spmi-pmic.c is probed (via the devm_of_platform_populate call) due to the interrupts property in device tree. Once spmi-gpio is converted to be a hierarchical IRQ chip in the next patch, existing users of gpio[d]_to_irq() will call pmic_gpio_to_irq(), and that will use the new IRQ chip code in spmi-gpio that sets up the IRQ in an IRQ hierarchy. The hwirq is now associated with two Linux virqs and interrupts will not work as expected. This patch corrects that issue. Driver was tested using gpio-keys and iadc/vadc on the LG Nexus 5 (hammerhead) phone.

* gpio: add irq domain activate/deactivate functionsBrian Masney2019-01-241-0/+37
| | | | | | | | | | | | | | This adds the two new functions gpiochip_irq_domain_activate and gpiochip_irq_domain_deactivate that can be used as the activate and deactivate functions in the struct irq_domain_ops. This is for situations where only gpiochip_{lock,unlock}_as_irq needs to be called. SPMI and SSBI GPIO are two users that will initially use these functions.

* spmi: pmic-arb: convert to v2 irq interfaces to support hierarchical IRQ chipsBrian Masney2019-01-241-20/+47
| | | | | | | | | | | | | | | | | | | | | | Convert the spmi-pmic-arb IRQ code to use the version 2 IRQ interface in order to support hierarchical IRQ chips. This is necessary so that spmi-gpio can be setup as a hierarchical IRQ chip with pmic-arb as the parent. IRQ chips in device tree should be usable from the start without the consumer having to make an additional call to gpio[d]_to_irq() to get the proper IRQ on the parent. The old qpnpint_irq_domain_map function would hardcode the handler as handle_level_irq, however qpnpint_irq_set_type would later override the handler. Properly set the handler when the IRQ is mapped. This new code doesn't return an error for IRQ_TYPE_NONE and preserves the existing behavior of using handle_level_irq since there are some broken device tree bindings that need to be corrected first.

* pinctrl: qcom: spmi-gpio: hardcode IRQ countsBrian Masney2019-01-211-17/+11
| | | | | | | | | | | | | | | | | | | | | | The probing of this driver calls platform_irq_count, which will setup all of the IRQs that are configured in device tree. In preparation for converting this driver to be a hierarchical IRQ chip, hardcode the IRQ count based on the hardware type so that all the IRQs are not configured immediately and are configured on an as-needed basis later in the boot process. This change will also allow for the removal of the interrupts property later in this patch series once the hierarchical IRQ chip support is in. This patch also removes the generic qcom,spmi-gpio OF match since we don't know the number of pins. All of the existing upstream bindings already include the more-specific binding. The pm8941 code was tested on a LG Nexus 5 (hammerhead) phone.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | EC_MKBP_EVENT_SENSOR_FIFO events can be triggered for a variety of reasons, and there are very few cases in which they should be treated as wakeup interrupts (particularly, when a certain MOTIONSENSE_MODULE_FLAG_* is set, but this is not even supported in the mainline cros_ec_sensor driver yet). Most of the time, they are benign sensor readings. In any case, the top-level cros_ec device doesn't know enough to determine that they should wake the system, and so it should not report the event. This would be the job of the cros_ec_sensors driver to parse. This patch adds checks to cros_ec_get_next_event() such that it doesn't signal 'wakeup' for events of type EC_MKBP_EVENT_SENSOR_FIFO. This patch is particularly relevant on devices like Scarlet (Rockchip RK3399 tablet, known as Acer Chromebook Tab 10), where the EC firmware reports sensor events much more frequently. This was causing /sys/power/wakeup_count to increase very frequently, often needlessly interrupting our ability to suspend the system.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cros_ec_get_next_event() is documented to return 0 for success and negative for errors. It currently returns negative for some errors, and non-negative (number of bytes received) for success (including some "no data available" responses as zero). This mostly works out OK, because the callers were more or less ignoring the documentation, and only treating positive values as success (and indepdently checking the modification of 'wakeup'). Let's button this up by avoiding pretending to handle event/wakeup distinctions when no event info was retrieved (i.e., returned 0 bytes). And fix the documentation of cros_ec_get_host_event() and cros_ec_get_next_event() to accurately describe their behavior.

In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway.

Our previous implementation did not account for this and results in every other pixel having very high luma value, showing greyish color instead of black. YCbCr444 = <Y1, Cb1, Cr1>; <Y2, Cb2, Cr2> ..... YCbCr420 = <Y1, Y2, Cb1>; <Y3, Y4, Cr1> ..... [How] Program the second channel with the black color value for luma as well.

Most of the time it isn't a real issue. [How] Make DC cool its jets - taking a while is a debug message (because it is not something that normal users should need to be aware of), and timeouts are warnings (because it technically shouldn't happen, but it's not a big deal if it does) Signed-off-by: David Francis <David.Francis@amd.com> Reviewed-by: Harry Wentland <Harry.Wentland@amd.com> Acked-by: Leo Li <sunpeng.li@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
