* 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().

* x86: tsc: Move tsc_timer.c to drivers/timerBin Meng2015-12-01-0/+397

* 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.

* timer: sandbox: Use device tree to pass the clock frequencyBin Meng2015-12-01-4/+0
| | | | | | | | We should use device tree to pass the clock frequency of the timer instead of hardcoded in the driver codes. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
* timer: altera: Remove the codes to get clock frequencyBin Meng2015-12-01-6/+0
| | | | | | | | | Since we have timer uclass to get clock frequency for us, remove the custom version in the altera timer driver. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Thomas Chou <thomas@wytron.com.tw> Acked-by: Simon Glass <sjg@chromium.org>
* dm: timer: Implement pre_probe()Bin Meng2015-12-01-0/+13
| | | | | | | | | | Every timer device needs to have a valid clock frequency and it can be specified in the device tree. Use pre_probe() to get this in the timer uclass driver.
