This patchset:
(1)Preparation for adding GTDT support in arm_arch_timer:
1. Move some enums and marcos to header file;
2. Add a new enum for spi type;
3. Improve printk relevant code.
4. rename some enums and defines, and some cleanups.
5. separate out arch_timer_uses_ppi init code and fix a potential bug
6. Refactor arch_timer_detect_rate to keep dt code only in *_of_init
7. Refactor arch_timer_needs_probing, and call it only if acpi disabled.
8. Introduce some new structs and refactor the timer init code
(2)Introduce ACPI GTDT parser: drivers/acpi/arm64/acpi_gtdt.c
Parse all kinds of timer in GTDT table of ACPI:arch timer,
memory-mapped timer and SBSA Generic Watchdog timer.
This driver can help to simplify all the relevant timer drivers,
and separate all the ACPI GTDT knowledge from them.
(3)Simplify ACPI code for arm_arch_timer
(4)Add GTDT support for ARM memory-mapped timer, also refactor
original memory-mapped timer dt support for reusing some common
code.
This patchset has been tested on the following platforms with ACPI enabled:
(1)ARM Foundation v8 model
Changelog:
v16: https://lkml.org/lkml/2016/
Fix patchset problem about static enum ppi_nr of 01/13 in v15.
Refactor arch_timer_detect_rate.
Refactor arch_timer_needs_probing.Most of the patches are touching drivers/clocksource and others acpi. Through which tree this patchset should go ?
