This series enhances timer uclass driver to support 64-bit counter value, and convert tsc timer to driver model to be used by all x86 boards.
As a result of dm conversion, the TSC_CALIBRATION_BYPASS Kconfig option is no longer needed, and the TSC frequency can be specified in the board device tree.
This v2 is rebased on top of u-boot-dm/master, to resolve conflicts with Altera timer updates and the new Sandbox timer driver.
Changes in v3:
- Update commit message to reflect the v2 changes (ie: there is no "counter-64bit" property)
- Really remove "counter-64bit" property from tsc_timer.dtsi
Changes in v2:
- Rebase on u-boot-dm/master
- Change 'Timer' to 'timer' in the sandbox timer Kconfig
- New patch to use device tree to pass the clock frequency
- Do not use "counter-64bit" property, instead create an inline function for 32-bit timer driver to construct a 64-bit timer value.
- Remove "counter-64bit" property

Thanks a lot. For the series,
