| * watchdog: sp805_wdt depends on ARMAlessandro Rubini2013-03-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SP805 driver is only used by the Spear machines, and uses writel_relaxed, which is not available on all architectures. The dependency from CONFIG_ARM avoids compilation problems under randomconfig when CONFIG_ARM_AMBA is enabled for x86 builds.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the existing STMP3xxx driver because it has enough drawbacks that a rewrite is apropriate. The new driver is designed to use the watchdog framework which makes it a lot smaller and avoids open coding the watchdog API again. It also uses now an explicitly exported function from the RTC driver to set up its registers (the old driver silently reused the hopefully(!) already remapped RTC registers). Also, this driver is mach independent, while the old one depends on a mach replaced by another one a year ago. Since the user interface is still the standard watchdog API, users don't need to adapt.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ath79_wdt driver uses a fixed memory address currently. Although this is working with each currently supported SoCs, but this may change in the future. Additionally, the driver includes platform specific header files in order to be able to get the memory base of the watchdog device. The patch adds a memory resource to the platform device, and converts the driver to get the base address of the watchdog device from that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | instead of zero In case of SP5100 or SB7x0 chipsets, the sp5100_tco module writes zero to reserved bits. The module, however, shouldn't depend on specific default value, and should perform a read-merge-write operation for the reserved bits. This patch makes the sp5100_tco module perform a read-merge-write operation on all the chipset (sp5100, sb7x0, sb8x0 or later).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | reserved bits In case of SB800 or later chipset and re-programming MMIO address(*), sp5100_tco module may read incorrect value of reserved bit, because the module reads a value from an incorrect I/O address. However, this bug doesn't cause a problem, because when re-programming MMIO address, by chance the module writes zero (this is BIOS's default value) to the low three bits of register. * In most cases, PC with SB8x0 or later chipset doesn't need to re-programming MMIO address, because such PC can enable AcpiMmio and can use 0xfed80b00 for watchdog register base address.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver will not quite work if someone unbinds the platform device from the platform driver via sysfs (moreover it will bomb is the driver built into the kernel as hp_wmi_bios_remove is marked as __exit and will not be present in the kernel). To fix it let's use platform_driver_probe() instead of platform_driver_register(), which disables binding/unbinding via sysfs. This also allows us to mark hp_wmi_bios_setup as __init and discard it once module is initialized.
