From: Thomas Gleixner <tglx@...utronix.de>
To: Linus Torvalds <torvalds@...ux-foundation.org>
Cc: linux-kernel@...r.kernel.org, x86@...nel.org
Subject: [GIT pull] timers/core for v5.7
Linus,
please pull the latest timers/core branch from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers-core-2020-03-30
up to: 4479730e9263: Revert "clocksource/drivers/timer-probe: Avoid creating dead devices"
timekeeping and timer updates:
Core:
- Consolidation of the vDSO build infrastructure to address the
difficulties of cross-builds for ARM64 compat vDSO libraries by
restricting the exposure of header content to the vDSO build.
This is achieved by splitting out header content into separate
headers. which contain only the minimaly required information which is
necessary to build the vDSO. These new headers are included from the
kernel headers and the vDSO specific files.
- Enhancements to the generic vDSO library allowing more fine grained
control over the compiled in code, further reducing architecture
specific storage and preparing for adopting the generic library by PPC.
- Cleanup and consolidation of the exit related code in posix CPU timers.
- Small cleanups and enhancements here and there
Drivers:
- The obligatory new drivers: Ingenic JZ47xx and X1000 TCU support
- Correct the clock rate of PIT64b global clock
- setup_irq() cleanup
- Preparation for PWM and suspend support for the TI DM timer
- Expand the fttmr010 driver to support ast2600 systems
- The usual small fixes, enhancements and cleanups all over the place
Thanks,
tglx
