KAGA-KOKO · KAGA-KOKO · commit 5146e1f589cc · 2023-08-31T03:21:22.000+02:00
Pull clocksource/clockdevice updates from Daniel Lezcano:

  - Remove oxnas the 0x810 and the 0x820 timer drivers, the platform
    being no longer maintained and removed (Neil Armstrong)

  - Disable the timer before programming the CVAL as there is no
    guarantee of atomicity on the ARM architected timer (Walter Chang)

  - Set variable ls1x_timer_lock static on the Loongson1 (Tom Rix)

  - Remove duplication of code and data by factoring out the structures
    into a single one and convert to the platform driver on the sun5i
    (Mans Rullgard)

  - Explicitly include correct DT includes (Rob Herring)
