drivers: timer: Introduce ARC timer driver

2017-03-24T11:20:55+00:00

This commit introduces timer driver for ARC.

ARC timers are configured via ARC AUX registers so we use special
functions to access timer control registers.

This driver allows utilization of either timer0 or timer1
depending on which one is available in real hardware. Essentially
only existing timers should be mentioned in board's Device Tree
description.

dm: core: Replace of_offset with accessor

2017-02-08T13:12:14+00:00

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

aspeed: Add drivers common to all Aspeed SoCs

2017-01-28T19:04:27+00:00

Add support for Watchdog Timer, which is compatible with AST2400 and
AST2500 watchdogs. There is no uclass for Watchdog yet, so the driver
does not follow the driver model. It also uses fixed clock, so no clock
driver is needed.

Add support for timer for Aspeed ast2400/ast2500 devices.
The driver actually controls several devices, but because all devices
share the same Control Register, it is somewhat difficult to completely
decouple them. Since only one timer is needed at the moment, this should
be OK. The timer uses fixed clock, so does not rely on a clock driver.

Add sysreset driver, which uses watchdog timer to do resets and particular
watchdog device to use is hardcoded (0)

timer: Support clocks via phandle

2016-12-27T16:24:10+00:00

Earlier timer driver needed a clock-frequency property in compatible
device-tree nodes. Another way is to reference a clock via a phandle.

So now timer_pre_probe tries to get clock by reference through device
tree. In case it is impossible to get clock device through the
reference, clock-frequency property of the timer node is read to provide
backward compatibility.

dm: omap_timer: Fix conversion of address to a pointer

2016-03-14T23:18:45+00:00

OMAP timer driver directly typecasts fdt_addr_t to a pointer. This is
not strictly correct, as it gives a build warning when fdt_addr_t is u64.
So, use map_physmem for a proper typecasts.

This is inspired by commit 167efe01bc5a9 ("dm: ns16550: Use an address
instead of a pointer for the uart base")

timer: Provide an early timer

2016-02-26T15:53:10+00:00

In some cases the timer must be accessible before driver model is active.
Examples include when using CONFIG_TRACE to trace U-Boot's execution before
driver model is set up. Enable this option to use an early timer. These
functions must be supported by your timer driver: timer_early_get_count()
and timer_early_get_rate().
