This patchset:
(1)Preparation for adding GTDT support in arm_arch_timer:
1. Clean up printk() usage
2. Rename the type macros
3. Rename the PPI enum & enum values
4. Move the type macro and PPI enum into the header file
5. Add new enum for SPIs
6. Rework PPI determination;
7. Rework counter frequency detection;
8. Refactor arch_timer_needs_probing, move it into DT init call
9. Introduce some new structs and refactor the MMIO timer init code
for reusing some common 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.
This patchset has been tested on the following platforms with ACPI enabled:
(1)ARM Foundation v8 model
Changelog:
v20: https://lkml.org/lkml/2017/1/18/
Reorder the first 4 patches and split the 4th patches.
Leave CNTHCTL_* as they originally were.
Fix the bug in arch_timer_select_ppi.
Split "Rework counter frequency detection" patch.
Rework the arch_timer_detect_rate function.
Improve the commit message of "Refactor MMIO timer probing".
Rebase to 4.10.0-rc4
Other than some minor comments I raised, the patch set
looks fine to me, and I tested this patch set on D03,
the percpu arch timer works fine as before.
With the comments fixed,
