2022-08-17pinctrl: Don't allow PINCTRL_AMD to be a moduleMario Limonciello
[ Upstream commit 41ef3c1a6bb0fd4a3f81170dd17de3adbff80783 ] 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.

2022-07-29pinctrl: armada-37xx: make irq_lock a raw spinlock to avoid invalid wait contextVladimir Oltean
[ Upstream commit 984245b66cf32c494b1e4f95f5ed6ba16b8771eb ] 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(), takes a plain spinlock, the kind that becomes 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. Replace the driver's irq_lock with a raw spinlock, to disable preemption even on RT.

[ Upstream commit ba9c4745fca70bf773b2d5c602dcd85d1a40b07a ] 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.

2022-07-29pinctrl: ocelot: Fix pincfg for lan966xHoratiu Vultur
[ Upstream commit dc62db7138aa9365480254dda4c3e1316b1b1bbc ] 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.

2022-07-29pinctrl: armada-37xx: use raw spinlocks for regmap to avoid invalid wait contextVladimir Oltean
commit 4546760619cfa9b718fe2059ceb07101cf9ff61e upstream. 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").

2022-04-23pinctrl: stm32: Keep pinctrl block clock enabled when LEVEL IRQ requestedMarek Vasut
The current EOI handler for LEVEL triggered interrupts calls clk_enable(), register IO, clk_disable(). The clock manipulation requires locking which happens with IRQs disabled in clk_enable_lock(). Instead of turning the clock on and off all the time, enable the clock in case LEVEL interrupt is requested and keep the clock enabled until all LEVEL interrupts are freed. The LEVEL interrupts are an exception on this platform and seldom used, so this does not affect the common case. This simplifies the LEVEL interrupt handling considerably and also fixes the following splat found when using preempt-rt: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 0 at kernel/locking/rtmutex.c:2040 __rt_mutex_trylock+0x37/0x62 Modules linked in: CPU: 0 PID: 0 Comm: swapper/0 Not tainted 5.10.109-rt65-stable-standard-00068-g6a5afc4b1217 #85 Hardware name: STM32 (Device Tree Support) [<c010a45d>] (unwind_backtrace) from [<c010766f>] (show_stack+0xb/0xc) [<c010766f>] (show_stack) from [<c06353ab>] (dump_stack+0x6f/0x84) [<c06353ab>] (dump_stack) from [<c01145e3>] (__warn+0x7f/0xa4) [<c01145e3>] (__warn) from [<c063386f>] (warn_slowpath_fmt+0x3b/0x74) [<c063386f>] (warn_slowpath_fmt) from [<c063b43d>] (__rt_mutex_trylock+0x37/0x62) [<c063b43d>] (__rt_mutex_trylock) from [<c063c053>] (rt_spin_trylock+0x7/0x16) [<c063c053>] (rt_spin_trylock) from [<c036a2f3>] (clk_enable_lock+0xb/0x80) [<c036a2f3>] (clk_enable_lock) from [<c036ba69>] (clk_core_enable_lock+0x9/0x18) [<c036ba69>] (clk_core_enable_lock) from [<c034e9f3>] (stm32_gpio_get+0x11/0x24) [<c034e9f3>] (stm32_gpio_get) from [<c034ef43>] (stm32_gpio_irq_trigger+0x1f/0x48) [<c034ef43>] (stm32_gpio_irq_trigger) from [<c014aa53>] (handle_fasteoi_irq+0x71/0xa8) [<c014aa53>] (handle_fasteoi_irq) from [<c0147111>] (generic_handle_irq+0x19/0x22) [<c0147111>] (generic_handle_irq) from [<c014752d>] (__handle_domain_irq+0x55/0x64) [<c014752d>] (__handle_domain_irq) from [<c0346f13>] (gic_handle_irq+0x53/0x64) [<c0346f13>] (gic_handle_irq) from [<c0100ba5>] (__irq_svc+0x65/0xc0) Exception stack(0xc0e01f18 to 0xc0e01f60) 1f00: 0000300c 00000000 1f20: 0000300c c010ff01 00000000 00000000 c0e00000 c0e07714 00000001 c0e01f78 1f40: c0e07758 00000000 ef7cd0ff c0e01f68 c010554b c0105542 40000033 ffffffff [<c0100ba5>] (__irq_svc) from [<c0105542>] (arch_cpu_idle+0xc/0x1e) [<c0105542>] (arch_cpu_idle) from [<c063be95>] (default_idle_call+0x21/0x3c) [<c063be95>] (default_idle_call) from [<c01324f7>] (do_idle+0xe3/0x1e4) [<c01324f7>] (do_idle) from [<c01327b3>] (cpu_startup_entry+0x13/0x14) [<c01327b3>] (cpu_startup_entry) from [<c0a00c13>] (start_kernel+0x397/0x3d4) [<c0a00c13>] (start_kernel) from [<00000000>] (0x0) ---[ end trace 0000000000000002 ]--- Power consumption measured on STM32MP157C DHCOM SoM is not increased or is below noise threshold.
