Date: Mon, 29 Aug 2011 11:09:49 +0200 From: Linus Walleij <linus.walleij@...ricsson.com> To: <linux-kernel@...r.kernel.org>, <linux-arm-kernel@...ts.infradead.org>, Grant Likely <grant.likely@...retlab.ca>, Stephen Warren <swarren@...dia.com> Cc: Lee Jones <lee.jones@...aro.org>, Joe Perches <joe@...ches.com>, Russell King <linux@....linux.org.uk>, Linaro Dev <linaro-dev@...ts.linaro.org>, Sascha Hauer <s.hauer@...gutronix.de>, David Brown <davidb@...eaurora.org>, Barry Song <21cnbao@...il.com>, Linus Walleij <linus.walleij@...aro.org> Subject: [PATCH 0/4 v5] pin controller subsystem v5 From: Linus Walleij <linus.walleij@...aro.org> This is the fifth iteration of the controller subsystem, most changes are described in the first patch, copied here for reference: ChangeLog v4->v5: - Defined a "position" for each function, so the pin controller now tracks a function in a certain position, and the pinmux maps define what position you want the function in. (Feedback from Stephen Warren and Sascha Hauer). - Since we now need to request a combined function+position from the machine mapping table that connect mux settings to drivers, it was extended with a position field and a name field. The name field is now used if you e.g. need to switch between two mux map settings at runtime. - Switched from a class device to using struct bus_type for this subsystem. Verified sysfs functionality: seems to work fine. (Feedback from Arnd Bergmann and Greg Kroah-Hartman) - Define a per pincontroller list of GPIO ranges from the GPIO pin space that can be handled by the pin controller. These can be added one by one at runtime. (Feedback from Barry Song) - Expanded documentation of regulator_[get|enable|disable|put] semantics. - Fixed a number of review comments from Barry Song. (Thanks!)
