Subject: [PATCH 5.19 08/38] gpio: mpc8xxx: Fix support for IRQ_TYPE_LEVEL_LOW flow_type in mpc85xx
Date: Wed, 21 Sep 2022 17:45:52 +0200	[thread overview]
Message-ID: <20220921153646.560374153@linuxfoundation.org> (raw)
In-Reply-To: <20220921153646.298361220@linuxfoundation.org>

From: Pali Rohár <pali@kernel.org>

[ Upstream commit 279c12df8d2efb28def9d037f288cbfb97c30fe2 ]

Commit e39d5ef67804 ("powerpc/5xxx: extend mpc8xxx_gpio driver to support
mpc512x gpios") implemented support for IRQ_TYPE_LEVEL_LOW flow type in
mpc512x via falling edge type. Do same for mpc85xx which support was added
in commit 345e5c8a1cc3 ("powerpc: Add interrupt support to mpc8xxx_gpio").

Fixes probing of lm90 hwmon driver on mpc85xx based board which use level
interrupt. Without it kernel prints error and refuse lm90 to work:

    [   15.258370] genirq: Setting trigger mode 8 for irq 49 failed (mpc8xxx_irq_set_type+0x0/0xf8)
    [   15.267168] lm90 0-004c: cannot request IRQ 49
    [   15.272708] lm90: probe of 0-004c failed with error -22

Fixes: 345e5c8a1cc3 ("powerpc: Add interrupt support to mpc8xxx_gpio")
