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 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
Bin Meng (11):
dm: timer: Fix several nits
dm: timer: Implement pre_probe()
timer: altera: Remove the codes to get clock frequency
timer: sandbox: Use device tree to pass the clock frequency
dm: timer: Support 64-bit counter
x86: Reomve MIN_PORT80_KCLOCKS_DELAY
x86: tsc: Use notrace from <linux/compiler.h>
x86: tsc: Add driver model timer support
x86: Convert to use driver model timer
x86: tsc: Remove legacy timer codes
x86: tsc: Move tsc_timer.c to drivers/timer
