Subject: [PATCH: V2 0/2] Fix TC35894 gpio interrupt bug
Date: Thu, 3 Sep 2020 15:30:20 +0800 [thread overview]
Message-ID: <1599118222-18990-1-git-send-email-dillon.minfei@gmail.com> (raw)
From: dillon min <dillon.minfei@gmail.com>
This patchset intend to fix two bug on tc35894
V2:
1 change V1[1] patch's Fixes tag
2 add DIRECTx register configuration in tc3589x_gpio_irq_sync_unlock()
to active general purpose gpio mode, else can't read correct
GPIOMISx to identify which interrupt
V1:
1 offset counting is wrong in tc3589x_gpio_irq_sync_unlock()
2 disable Direct KBD interrupts in gpio-tc3589x's probe(),
at least have to do this on tc35894, if not, after chip reset,
IRQST(0x91) will always be 0x20, IRQN always low level,
can't be cleared. need more test on other tc3589x.
