The EP93xx features two PWMs (one on the EP9307) with the following features: * Configurable dual output * Separate input clocks for each PWM output * 16-bit resolution * Programmable pulse width (duty cycle), interval (frequency), and polarity This adds the necessary core support as well as the driver. A sysfs interface is provided to control the PWM outputs.

The EP93xx has two gpio pins specifically assigned to drive external LEDs. Add core support for these LEDs. On the EDB93xx development boards, the rdled is connected to an external reset circuit. Turning this led on for an extended amount of time will cause the circuit to issue a manual reset. Refer to Cirrus App Note AN258 for more information. http://www.cirrus.com/en/pubs/appNote/AN258REV2.pdf This led can be safely used as the system heartbeat with the ledtrig-heartbeat driver. echo heartbeat > /sys/class/leds/platform:rdled/trigger The grled can be used for any desired purpose.

The MAC address for the ep93xx ethernet driver can be optionally copied from registers in the controller when booting. Due to [ARM] 5573/1: ep93xx: ensure typesafe io, the cast for the source address is no longer needed. EP93XX_ETHERNET_BASE is typed as a (void __iomem __force *) so memcpy_fromio() needs to be used instead of memcpy().

Remove including the ts72xx.h header. This header is not generic to the ep93xx platform. It should only be included by the ts72xx specific files that require it.

Add core functions to handle writes to the ep93xx software locked registers. There are a number of registers in the EP93xx System Controller that require a write to the software lock register before they can be updated. This patch adds a number of exported functions to the ep93xx core that handle this access. The software locked clock divider registers, VidClkDiv, MIRClkDiv, I2SClkDiv and KeyTchClkDiv would typically involve writing a specific value to the register. To support this the ep93xx_syscon_swlocked_write() function is provided. For the DeviceCfg register it's more typical to only need to set or clear a single bit. A generic ep93xx_devcfg_set_clear() function is provided to handle both operations. Two inline functions, ep93xx_devcfg_set_bits() and ep93xx_devcfg_clear_bits() are also provided to improve code readability. In addition, the remaining bits in the System Controller Device Config Register have been documented and the previously defined names shortened. All code paths that use this functionality have been updated except for arch/arm/kernel/crunch.c. That code is in a context switch path, which is not reentrant, so it is safe against itself.

Add power management support to the VIC by registering each VIC as a system device to get suspend/resume events going. Since the VIC registeration is done early, we need to record the VICs in a static array which is used to add the system devices later once the initcalls are run. This means there is now a configuration value for the number of VICs in the system. Signed-off-by: NBen Dooks <ben-linux@fluff.org>

Update the rtc-ep93xx driver to use ioremap'ed addresses. This removes the dependency on <mach/hardware.h> and properly reports the memory addresses used by the driver in /proc/iomem. In addition, ep93xx_rtc_init() is updated to use platform_driver_probe() instead of platform_driver_register(). Also, the device_create_file() calls are now properly checked for error conditions. The created sysfs files are also now removed when the driver is removed. The version number for the driver has been bumped at the request of Alessandro Zummo.

Add debounce support for ep93xx gpio interrupts. On the EP93xx, GPIO ports A, B, and F can be used to generate interrupts. For each port, if interrupts are enabled, it is possible to debouce the input signal. Debouncing is implemented by passing the input signal through a 2-bit shift register clocked by a 128Hz clock. This patch adds a platform specific way to enable the debouce feature for these input ports.
