2012-04-22gpio: Add missing spin_lock_init in gpio-pch driverAxel Lin
commit d166370ad86b33b1111af3a0cdd7de94e03789a6 upstream. This bug was introduced by commit d568a681 "gpio-pch: add spinlock in suspend/resume processing" which adds a spinlock to struct pch_gpio but never init the spinlock.

2011-10-31drivers/gpio: Fix drivers who are implicit users of module.hPaul Gortmaker
A pending cleanup will mean that module.h won't be implicitly everywhere anymore. Make sure the modular drivers in gpio are actually calling out for <module.h> explicitly in advance. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-19gpio-pch: Use NUMA_NO_NODE not GFP_KERNELTomoya MORINAGA
Currently, GFP_KERNEL is used as parameter of irq_alloc_descs like below. irq_base = irq_alloc_descs(-1, IOH_IRQ_BASE, num_ports[j], GFP_KERNEL); This is not true. So, this patch uses NUMA_NO_NODE not GFP_KERNEL.

2011-10-05gpio-pch: Save register value in suspend()Tomoya MORINAGA
Currently, when suspend is occurred, register im0/1 and gpio_use_sel are not saved. This patch modifies so that register im0/1 and gpio_use_sel are saved. Signed-off-by: Tomoya MORINAGA <tomoya-linux@dsn.okisemi.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-10-05gpio-pch: modify gpio_nums and maskTomoya MORINAGA
Currently, the number of GPIO pins is set fixed value(=12). Also PIN MASK is set as '0xfff'. However the pins differs by IOH. This patch sets the value correctly. Signed-off-by: Tomoya MORINAGA <tomoya-linux@dsn.okisemi.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
