2025-05-13gpio: virtuser: fix potential out-of-bound writeMarkus Burri1-2/+10
If the caller wrote more characters, count is truncated to the max available space in "simple_write_to_buffer". Check that the input size does not exceed the buffer size. Write a zero termination afterwards.

2025-05-13gpio: pca953x: fix IRQ storm on system wake upEmanuele Ghidoli1-0/+6
If an input changes state during wake-up and is used as an interrupt source, the IRQ handler reads the volatile input register to clear the interrupt mask and deassert the IRQ line. However, the IRQ handler is triggered before access to the register is granted, causing the read operation to fail. As a result, the IRQ handler enters a loop, repeatedly printing the "failed reading register" message, until `pca953x_resume()` is eventually called, which restores the driver context and enables access to registers. Fix by disabling the IRQ line before entering suspend mode, and re-enabling it after the driver context is restored in `pca953x_resume()`. An IRQ can be disabled with disable_irq() and still wake the system as long as the IRQ has wake enabled, so the wake-up functionality is preserved.

2025-04-14gpio: GPIO_BLZP1600 should depend on ARCH_BLAIZEGeert Uytterhoeven1-0/+1
The Blaize BLZP1600 GPIO controller is only present on BLaize BLZP1600 SoCs. Hence add a dependency on ARCH_BLAIZE, to prevent asking the user about this driver when configuring a kernel without Blaize platform support.
