* dm: timer: refuse timers with zero clock_rateStephen Warren2016-01-201-0/+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>
* dm: timer: uclass: Add flag to control sequence numberingMugunthan V N2016-01-201-0/+1
| | | | | | | | | | | | Like SPI and I2C, timer devices also have multiple chip instances. This patch adds the flag 'DM_UC_FLAG_SEQ_ALIAS' in timer_uclass driver to control device sequence numbering.

* dm: timer: uclass: add timer init in uclass driver to add timer deviceMugunthan V N2016-01-201-0/+44
| | | | | | | | | | Adding timer init function in timer-uclass driver to create and initialize the timer device on platforms where u-boot,dm-pre-reloc is not used. Since there will be multiple timer devices in the system, adding a tick-timer node in chosen node to know which timer device to be used as tick timer in u-boot.

* dm: timer: Support 64-bit counterBin Meng2015-12-011-3/+12
| | | | | | | | | | | | 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.

* dm: timer: Implement pre_probe()Bin Meng2015-12-011-0/+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.
