| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make use of the hierarchical interrupt rergister called ITLatchHier1 - 3 also for the 8500 platform (currently the hierarchical interrupt registers are used only for the 8540 and 9540 platforms). This will make the interrupt routing go faster since fewer i2c reads need to made in the most common cases.

| * | mfd: ab8500-debug: Add explicit dependenciesLinus Walleij2013-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As I am working on SPARSE_IRQ a number of implicit resource grabs in the kernel become evident. For example, some includes like <linux/irqs.h> would implicitly include <mach/irqs.h> and then from there <mach/db8500-regs.h>. In many cases it is masking the fact that drivers do not properly use resources to pass their dependencies, base addresses etc. So write explicit #include statements with TODO items to have this fixed the proper way to all drivers doing this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CONFIG_MFD_CROS_EC requires CONFIG_MFD_CORE for a couple of functions that are declared but not defined: ERROR: "mfd_remove_devices" [drivers/mfd/cros_ec.ko] undefined! ERROR: "mfd_add_devices" [drivers/mfd/cros_ec.ko] undefined! Fix it by selecting CONFIG_MFD_CORE anytime CONFIG_MFD_CROS_EC is enabled.

* | | mfd: Add ChromeOS EC SPI driverSimon Glass2013-04-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This uses a SPI bus to talk to the ChromeOS EC. The protocol is defined by the EC and is fairly simple, with a length byte, checksum, command byte and version byte (to permit easy creation of new commands).
