Hi,
Back in January I sent patches adding pinconf support
for configuring mcp23s08's pull-ups. Apart from my
custom Raspberry Pi setup the pull-up support is also
needed by Toby Churchill SL50.
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
I did not add a stub for GPIO_MCP23S08 selecting the
new PINCTRL_MCP23S08, since that would require a copy
of all "depends on" information, which is quite messy.
Also it seems to be quite unusual (I found no instance
of a select being used for a renamed config option).
I see the following merge strategies:
a) Ignore limited bisectability and merge all
patches through their own subsystem. Compilation
should always succeed, but the blackfin boards
will be without mcp23s08 support with only one of
patch 1 and 2 being applied.
b) - Squash patch 1 & 2
- Queue that patch into gpio/pinctrl
- Provide immutable-branch for blackfin & arm
- Blackfin & ARM can pull immutable-branch & apply defconfig patch
- gpio/pinctrl can queue patch 5 & 6
c) The same as b), but squash patch 1-4 to guarantee
bisectability for defconfig.
