* | dm: omap_timer: Fix conversion of address to a pointerLokesh Vutla2016-03-14-1/+2
|/ | | | | | | | | | | | 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") Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>

* timer: Provide an early timerSimon Glass2016-02-26-0/+10
| | | | | | | | | | 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(). Signed-off-by: Simon Glass <sjg@chromium.org>
* timer: Support tracing fullySimon Glass2016-02-26-3/+3
| | | | | | | A few of the functions in the timer uclass are not marked with 'notrace'. Fix this so that tracing can be used with CONFIG_TRACE. Signed-off-by: Simon Glass <sjg@chromium.org>
* timer: sandbox: work without device treeStephen Warren2016-01-20-0/+10
| | | | | | | | | | | | | | | A default invocation of sandbox U-Boot apparently uses no device tree, which means that no timer is registers, which in turn means that the sleep shell command hangs. Fix the sandbox timer code to register a device when there's no DT, just like e.g. the sandbox reset driver does. When there's no DT, the DM uclass can't initialize clock_rate from DT, so set a default value in the timer code instead.

* dm: timer: refuse timers with zero clock_rateStephen Warren2016-01-20-0/+11
| | | | | | | | | If a timer has a zero clock_rate, get_tbclk() will return zero for it, which will cause tick_to_time() to perform a division-by-zero, which will crash U-Boot. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org>

* x86: Move i8254_init() to x86_cpu_init_f()Bin Meng2015-12-09-10/+0
| | | | | | | | | | | Right now i8254_init() is called from timer_init() in the tsc timer driver. But actually i8254 and tsc are completely different things. Since tsc timer has been converted to driver model, we should find a new place that is appropriate for U-Boot to call i8254_init(), which is now x86_cpu_init_f().

* dm: timer: Support 64-bit counterBin Meng2015-12-01-6/+15
| | | | | | | | | | | | There are timers with a 64-bit counter value but current timer uclass driver assumes a 32-bit one. Modify timer_get_count() to ask timer driver to always return a 64-bit counter value, and provide an inline helper function timer_conv_64() to handle the 32-bit/64-bit conversion automatically.
