[PATCHv3 00/14] mcp23s08 pinconf & cleanup

[Sebastian Reichel]

Hi,

Here is a rebase of my PATCHv2 in combination with the second patchset, which
migrates to regmap based register caching. I also added a few more patches, that
do misc. cleanups in the driver and remove ~100 loc (that's 10%).

The first patch and the 12th patch ("simplify spi_present_mask handling") needs
Acked-by from Steven Miao for the blackfin architecture changes (defconfig, two
boardfiles) and from Vladimir Zapolskiy or Sylvain Lemieux for the lpc32xx_defconfig
changes.

Changes since PATCHv1:
 * Add patch moving mcp23s08 from gpio/ to pinctrl/
 * Add patches updating config references in arch/
 * Add patch removing pdata support for pullup config
Changes since PATCHv2:
 * rebase to v4.12-rc1
 * squash patch 1-4 for bisectability
 * use devm_pinctrl_register in patch adding pinctrl support
 * include patchset for regmap based caching
 * constify structs in patch switching to regmap caching
 * add new patches with more cleanups (-120 locs)
