2022-07-19pinctrl: armada-37xx: use raw spinlocks for regmap to avoid invalid wait contextVladimir Oltean1-6/+21
The irqchip->irq_set_type method is called by __irq_set_trigger() under the desc->lock raw spinlock. The armada-37xx implementation, armada_37xx_irq_set_type(), uses an MMIO regmap created by of_syscon_register(), which uses plain spinlocks (the kind that are sleepable on RT). Therefore, this is an invalid locking scheme for which we get a kernel splat stating just that ("[ BUG: Invalid wait context ]"), because the context in which the plain spinlock may sleep is atomic due to the raw spinlock. We need to go raw spinlocks all the way. Make this driver create its own MMIO regmap, with use_raw_spinlock=true, and stop relying on syscon to provide it. This patch depends on commit 67021f25d952 ("regmap: teach regmap to use raw spinlocks if requested in the config").

2022-07-18pinctrl: Don't allow PINCTRL_AMD to be a moduleMario Limonciello1-1/+1
It was observed that by allowing pinctrl_amd to be loaded later in the boot process that interrupts sent to the GPIO controller early in the boot are not serviced. The kernel treats these as a spurious IRQ and disables the IRQ. This problem was exacerbated because it happened on a system with an encrypted partition so the kernel object was not accesssible for an extended period of time while waiting for a passphrase. To avoid this situation from occurring, stop allowing pinctrl-amd from being built as a module and instead require it to be built-in or disabled.

This SoC contains a pinctrl with a new register layout. Use the variant parameter to set the right register offsets. This pinctrl also increases the number of functions per pin from 8 to 16, taking advantage of all 4 bits in the mux config field (so far, only functions 0-8 and 14-15 are used). This increases the maximum possible number of functions.

2022-07-18pinctrl: sunxi: Make some layout parameters dynamicSamuel Holland2-18/+29
Starting with the D1/D1s/T113 SoC, Allwinner changed the layout of the pinctrl registers. This new layout widens the drive level field, which affects the pull register offset and the overall bank size. In order to support multiple register layouts, some of the layout parameters need to be set based on the pinctrl variant. This requires passing the pinctrl struct pointer to the register/offset calculation functions.

2022-07-18pinctrl: sunxi: Refactor register/offset calculationSamuel Holland2-123/+89
Starting with the D1/D1s/T113 SoC, Allwinner changed the layout of the pinctrl registers. This new layout widens the drive level field, which affects the pull register offset and the overall bank size. As a first step to support this, combine the register and offset calculation functions, and refactor the math to depend on one constant for field widths instead of three. This minimizes the code size impact of making some of the factors dynamic. While rewriting these functions, move them to the implementation file, since that is the only file where they are used. And make the comment more generic, without mentioning specific offsets/sizes. The callers are updated to expect a shifted mask, and to use consistent terminology (reg/shift/mask/val).

The blamed commit changed to use regmaps instead of __iomem. But it didn't update the register offsets to be at word offset, so it uses byte offset. Another issue with the same commit is that it has a limit of 32 registers which is incorrect. The sparx5 has 64 while lan966x has 77.

The blamed commit introduce support for lan966x which use the same pinconf_ops as sparx5. The problem is that pinconf_ops is specific to sparx5. More precisely the offset of the bits in the pincfg register are different and also lan966x doesn't have support for PIN_CONFIG_INPUT_SCHMITT_ENABLE. Fix this by making pinconf_ops more generic such that it can be also used by lan966x. This is done by introducing 'ocelot_pincfg_data' which contains the offset and what is supported for each SOC.

2022-07-10gpio: Remove dynamic allocation from populate_parent_alloc_arg()Marc Zyngier1-9/+6
The gpiolib is unique in the way it uses intermediate fwspecs when feeding an interrupt specifier to the parent domain, as it relies on the populate_parent_alloc_arg() callback to perform a dynamic allocation. This is pretty inefficient (we free the structure almost immediately), and the only reason this isn't a stack allocation is that our ThunderX friend uses MSIs rather than a FW-constructed structure. Let's solve it by providing a new type composed of the union of a struct irq_fwspec and a msi_info_t, which satisfies both requirements. This allows us to use a stack allocation, and we can move the handful of users to this new scheme. Also perform some additional cleanup, such as getting rid of the stub versions of the irq_domain_translate_*cell helpers, which are never used when CONFIG_IRQ_DOMAIN_HIERARCHY isn't selected. Tested on a Tegra186.
