Pin control fixes for v4.11, take two:

Browse Source 
- Kconfig fixup for the TI IOdelay pinctrl-single add-on.
 
 - Fix up a typo in the meson i2c ao groups.
 
 - Switch a remapping back to use devm_ioremap() as
   devm_ioremap_resource() does not allow for sharing memory
   regions.
 
 - Do not clear the Qualcomm irq status bit in irq_unmask(),
   as this can lead to missing interrupts while the irq handler
   is executing.
 
 - Add irq_request/release_resources() on the ST driver.
 
 - Add a bunch of mysteriously missing pingroups for high
   numbered pins in the Qualcomm ipq4019 driver.

Merge tag 'pinctrl-v4.11-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull more pin control fixes from Linus Walleij:
 "Here is a bunch of pin control fixes again

  A bit more than I'd like for this subsystem at this point, but what
  can I do. They are all driver fixes for hardware issues, as like "we
  forgot", "we didn't think of the fact that this could happen", "oops
  that one goes there" etc

   - Kconfig fixup for the TI IOdelay pinctrl-single add-on

   - fix up a typo in the meson i2c ao groups

   - switch a remapping back to use devm_ioremap() as
     devm_ioremap_resource() does not allow for sharing memory regions

   - do not clear the Qualcomm irq status bit in irq_unmask(), as this
     can lead to missing interrupts while the irq handler is executing

   - add irq_request/release_resources() on the ST driver

   - add a bunch of mysteriously missing pingroups for high numbered
     pins in the Qualcomm ipq4019 driver"

* tag 'pinctrl-v4.11-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:
  pinctrl: qcom: ipq4019: add missing pingroups for pins > 70
  pinctrl: st: add irq_request/release_resources callbacks
  pinctrl: qcom: Don't clear status bit on irq_unmask
  pinctrl: samsung: Fix memory mapping code
  pinctrl: meson-gxbb: Fix typo in i2c ao groups
  pinctrl: ti: The IODelay driver is a DRA7xxx feature so depend on that SoC
