If the gmac-m1 optimization(bit10) is selected, the gpio function
of gmac pins is not valid. We may use the rmii mode for gmac interface,
the pins such as rx_d2, rx_d3, which the rgmii mode used, but rmii not
used could be taken as gpio function. So gmac_rxd0m1 selects the bit2,
and gmac_rxd0m3 select bit10 is more correct.

The touchpad in the Asus laptop models X505BA/BP and X542BA/BP is
unresponsive after suspend/resume. The following error appears during
resume:
i2c_hid i2c-ELAN1300:00: failed to reset device.
The problem here is that i2c_hid does not notice the interrupt being
generated at this point, because the GPIO is no longer configured
for interrupts.
Fix this by saving pinctrl-amd pin registers during suspend and
restoring them at resume time.
Based on code from pinctrl-intel.

This patch moves the initialization of the mask field in the irq_startup
function. However some callbacks such as irq_set_type and irq_set_wake
could be called before irq_startup. For those functions the mask is
computed at each call which is not a issue as these functions are not
located in a hot path but are used sporadically for configuration.

This reverts commit 2154d94b40.
The original patch was intented to avoid some issues with the sunxi
gpio rework and was supposed to be reverted after all the required
DT bits had been merged around v4.10.

In the same way as it's done in pinctrl-cherryview.c we would provide
a readback TX buffer state.

The pins from GPIO1A0 to GPIO1B1 are special, need to recalculate
iomux. And the register offset is larger than the u8 range, so changed
to u32.

The OF node name already contains the gpio chip identifier, no need to
append it when creating the label.
The following debug message clearly shows the suffix is not required

Yong Li found that writes to the AST2500 strapping register were not
properly supported by the Aspeed pinctrl core and provided a patch to
rectify the problem. Several revisions of the patch were posted and
ultimately v4 should have been applied, however some unfortunate
liberal application of tags on my part lead to confusion between v3[1]
and v4[2].
Generate the diff between v3 and v4 to apply as a fixup patch.
