Subject: [PATCH v1 0/1] i2c: npcm: unexpected SLVRSTR IRQ in master mode
Date: Tue, 23 Jun 2026 13:46:34 +0800 [thread overview]
Message-ID: <20260623054635.1214525-1-kcfeng0@nuvoton.com> (raw)
From: Ban Feng <kcfeng0@nuvoton.com>
SLVRSTR IRQ occurs even when BMC acts as master role only.
This case was not handled in the master IRQ handler,
resulting in IRQ storming.
Handle this condition to prevent the spurious interrupt.
