H A D | h3xxx.h | 40ca061b Wed Sep 25 07:33:55 CDT 2013 Linus Walleij <linus.walleij@linaro.org> ARM: 7841/1: sa1100: remove complex GPIO interface
The SA1100 was implementing its own variants of gpio_get_value() and gpio_set_value() and only selectively falling back to gpiolib for extended (EGPIO) handling. However the driver in gpio/gpio-sa1100.c already handles the same functionality for these lines, yet remain unused.
The only upside would be things like a timing-critical hotpath on bit-banged GPIO, but that kind of things does not seem to happen on these GPIOs, so it is not worth having the extra complexity.
Tested with some buttons on the Compaq iPAQ H3630.

H A D | collie.h | 052450fd Tue Feb 25 15:41:41 CST 2014 Linus Walleij <linus.walleij@linaro.org> ARM: 7991/1: sa1100: fix compile problem on Collie
Due to a problem in the MFD Kconfig it was not possible to compile the UCB battery driver for the Collie SA1100 system, in turn making it impossible to compile in the battery driver. (See patch "mfd: include all drivers in subsystem menu".)
After fixing the MFD Kconfig (separate patch) a compile error appears in the Collie battery driver due to the <mach/collie.h> implicitly requiring <mach/hardware.h> through <linux/gpio.h> via <mach/gpio.h> prior to commit 40ca061b "ARM: 7841/1: sa1100: remove complex GPIO interface".
Fix this up by including the required header into <mach/collie.h>.
