Subject: [PATCH AUTOSEL 4.19 027/167] ARM: davinci: dm646x: define gpio interrupts as separate resources

From: Bartosz Golaszewski <bgolaszewski@...libre.com>

[ Upstream commit 2c9c83491f30afbce25796e185cd4d5e36080e31 ]

Since commit eb3744a2dd01 ("gpio: davinci: Do not assume continuous
IRQ numbering") the davinci GPIO driver fails to probe if we boot
in legacy mode from any of the board files. Since the driver now
expects every interrupt to be defined as a separate resource, split
the definition of IRQ resources instead of having a single continuous
interrupt range.

Fixes: eb3744a2dd01 ("gpio: davinci: Do not assume continuous IRQ numbering")
