Subject: [PATCH v1 01/16] pinctrl: cy8c95x0: Respect IRQ trigger settings from firmware
Date: Fri, 17 Jan 2025 16:21:45 +0200	[thread overview]
Message-ID: <20250117142304.596106-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20250117142304.596106-1-andriy.shevchenko@linux.intel.com>

Som of the platforms may connect the INT pin via inversion logic
effectively make the triggering to be active-low.
Remove explicit trigger flag to respect the settings from firmware.

Without this change even idling chip produces spurious interrupts
and kernel disables the line in the result:

  irq 33: nobody cared (try booting with the "irqpoll" option)
  CPU: 0 UID: 0 PID: 125 Comm: irq/33-i2c-INT3 Not tainted 6.12.0-00236-g8b874ed11dae #64
  Hardware name: Intel Corp. QUARK/Galileo, BIOS 0x01000900 01/01/2014
  ...
  handlers:
  [<86e86bea>] irq_default_primary_handler threaded [<d153e44a>] cy8c95x0_irq_handler [pinctrl_cy8c95x0]
  Disabling IRQ #33

Fixes: e6cbbe42944d ("pinctrl: Add Cypress cy8c95x0 support")
