As this driver is using pinconf_generic_dt_node_to_map_pin() it needs to depend on OF so as not to cause build problems on archs that do not support OF. Cc: Sherman Yin <syin@broadcom.com> Signed-off-by: -

Adds pinctrl driver for Broadcom Capri (BCM281xx) SoCs. v4: - PINCTRL selected in Kconfig, PINCTRL_CAPRI selected in bcm_defconfig - make use of regmap - change CAPRI_PIN_UPDATE from macro to inline function. - Handle pull-up strength arg in Ohm instead of enum v3: Re-work driver to be based on generic pin config. Moved config selection from Kconfig to bcm_defconfig. v2: Use hyphens instead of underscore in DT property names. Signed-off-by: -

Adds pinctrl driver devicetree binding for Broadcom Capri (BCM281xx) SoCs. v4: Changed valid values for "bias-pull-up" property for I2C pins. Expanded pin configuration node example. v3: Use generic pin config properties instead of brcm-specific ones. Clarified pin types (standard, i2c, hdmi). v2: Use hyphens instead of underscore in DT property names.

This uses the new API for tagging GPIO lines as in use by IRQs. This enforces a few semantic checks on how the underlying GPIO line is used. Also assign the gpio_chip.dev pointer to be used for error messages. Cc: Barry Song <Baohua.Song@csr.com> Signed-off-by: -

busses like i2c, spi and so on can parse the virq of their subnode automatically by irq_of_parse_and_map(). for example, i2c will do that in of_i2c_register_devices(). people can put hwirq number attached to a gpio controller in dts, and drivers can directly request the parsed virq. for example, for an i2c client as below, tangoc-ts@5c{ compatible = "pixcir,tangoc-ts"; interrupt-parent = <&gpio>; interrupts = <3 0>; reg = <0x5c>; }; in i2c client probe(), it will request_irq(client->irq, ...) without calling gpio_direction_input(). so here when we set irq type, we also put the pin to input direction.

in sirfsoc gpio probe(), we create 5 irq_domains for 5 gpio banks. but in irq_create_of_mapping() of irqchip core level, irq_find_host() can only return the 1st irq_domain attached the pinctrl dt device node as we can see from the codes: unsigned int irq_create_of_mapping(struct device_node *controller, const u32 *intspec, unsigned int intsize) { struct irq_domain *domain; ... domain = controller ? irq_find_host(controller) : irq_default_domain; } struct irq_domain *irq_find_host(struct device_node *node) { struct irq_domain *h, *found = NULL; int rc; /* We might want to match the legacy controller last since * it might potentially be set to match all interrupts in * the absence of a device node. This isn't a problem so far * yet though... */ mutex_lock(&irq_domain_mutex); list_for_each_entry(h, &irq_domain_list, link) { if (h->ops->match) rc = h->ops->match(h, node); else rc = (h->of_node != NULL) && (h->of_node == node); if (rc) { found = h; break; } } mutex_unlock(&irq_domain_mutex); return found; } for sirfsoc, the 1st irq_domain attached to the device_node(controller) only can do linear for the 1st 32 gpios. so for devices who use gpio hwirq above 32 and put the information in dt like: tangoc-ts@5c{ compatible = "pixcir,tangoc-ts"; + interrupt-parent = <&gpio>; + interrupts = <34 0>; }; we will fail to get the virq for these devices as hwirq will be bigger than domain->revmap_data.linear.size in: unsigned int irq_linear_revmap(struct irq_domain *domain, irq_hw_number_t hwirq) { /* Check revmap bounds; complain if exceeded */ if (WARN_ON(hwirq >= domain->revmap_data.linear.size)) return 0; return domain->revmap_data.linear.revmap[hwirq]; } this patch drops redundant irq_domain and keep only one to fix the problem.

commit 4e7e8017 (pinctrl: pinctrl-single: enhance to configure multiple pins of different modules) improved support for pinctrl-single,bits option, but also caused a regression in parsing badly configured mask data. If the masks in DT data are not quite right, pcs_parse_bits_in_pinctrl_entry() can end up in an infinite loop, trashing memory at the same time. Add a check to verify that each loop actually removes bits from the 'mask', so that the loop can eventually end. Signed-off-by:

This adds a driver for the Tegra124 pinmux, and required parameterization data for Tegra124. The driver uses the common Tegra pincontrol driver utility functions to implement the majority of the driver. This driver is not compatible with the earlier NVIDIA's SoCs, hence add new compatibile as "nvidia,tegra124-pinmux". Originally written by Ashwini Gguhe. Thierry: - Cleanups in patches. ldewangan: - Fix some entries for groups. - Fix MUX enums and group sequence. Signed-off-by:
