* mfd: Fix sm501_register_gpio section mismatchRakib Mullick2009-02-171-1/+1
| | | | | | | | | | | | | WARNING: drivers/mfd/built-in.o(.text+0x1706): Section mismatch in reference from the function sm501_register_gpio() to the function .devinit.text:sm501_gpio_register_chip() The function sm501_register_gpio() references the function __devinit sm501_gpio_register_chip(). This is often because sm501_register_gpio lacks a __devinit annotation or the annotation of sm501_gpio_register_chip is wrong.

* mfd: Ensure sm501 GPIO pin mode is GPIO when configuredBen Dooks2009-01-111-2/+28
| | | | | | | | | | When setting an GPIO to either input or output, we should ensure that the pin configuration elsewhere in the chip is set to GPIO in-case the initial setup has not been done correctly.

* mfd: check for platform_get_irq() return value in sm501Roel Kluin2008-10-221-11/+11

* mfd: use pci_ioremap_bar() in sm501Arjan van de Ven2008-10-221-2/+1
| | | | | | | | | | Use the newly introduced pci_ioremap_bar() function in drivers/mfd. pci_ioremap_bar() just takes a pci device and a bar number, with the goal of making it really hard to get wrong, while also having a central place to stick sanity checks.

| | | | | | | | | | | Fix the build problems if CONFIG_MFD_SM501_GPIO is not set, which is generally when there is no gpiolib support available as currently happens on x86 when building PCI SM501.

| | | | | | | | | | | | The SM501 PCI card requires a dyanmic gpio allocation as the number of cards is not known at compile time. Fixup the platform data and registration to deal with this.

* sm501: add uart supportMagnus Damm2008-04-281-16/+68
| | | | | | | | | | | | This patch extends the sm501 mfd with 8250 uart support. We're currently doing this in the board specific r2d-1 code already, but it would be nice to do move things into the mfd since it's more chip specific than board specific.
