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
