Subject: [PATCH] pinctrl: baytrail: Move IRQ valid mask initialization to a dedicated callback
Git-commit: e70982b3abec4fb6e2ce9489f071080ca84e4bc7
Patch-mainline: v5.6-rc1
References: jsc#SLE-12730
There is a logical continuation of the commit 5fbe5b5883f8 ("gpio: Initialize
the irqchip valid_mask with a callback") to split IRQ initialization to
hardware and valid mask setup parts.
