From: Fu Wei <fu.wei@xxxxxxxxxx>
This patchset:
(1)Move some enums and marcos to header file for arm_arch_timer,
improve the pr_* code by defining "pr_fmt(fmt)" in arm_arch_timer.c
(2)Introduce ACPI GTDT parser: drivers/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 arch timer in arm_arch_timer.c
(4)Add memory-mapped timer support in arm_arch_timer.c
RESEND:
-- Corrected Cc list: added missing mailing lists
Changelog:
v4: https://lists.linaro.org/pipermail/linaro-acpi/2016-March/006667.html
Delete the kvm relevant patches
Separate two patches for sorting out the code for arm_arch_timer.
Improve irq info export code to allow missing irq info in GTDT table.
v3: https://lkml.org/lkml/2016/2/1/658
Improve GTDT driver code:
(1)improve pr_* by defining pr_fmt(fmt)
(2)simplify gtdt_sbsa_gwdt_init
(3)improve gtdt_arch_timer_data_init, if table is NULL, it will try
to get GTDT table.
Move enum ppi_nr to arm_arch_timer.h, and add enum spi_nr.
Add arm_arch_timer get ppi from DT and GTDT support for kvm.
v2: https://lkml.org/lkml/2015/12/2/10
Rebase to latest kernel version(4.4-rc3).
Fix the bug about the config problem,
use CONFIG_ACPI_GTDT instead of CONFIG_ACPI in arm_arch_timer.c
v1: The first upstreaming version: https://lkml.org/lkml/2015/10/28/553
