From mboxrd@z Thu Jan 1 00:00:00 1970 From: fu.wei@linaro.org (fu.wei at linaro.org) Date: Thu, 30 Jun 2016 02:15:43 +0800 Subject: [PATCH v6 00/10] acpi, clocksource: add GTDT driver and GTDT support in arm_arch_timer Message-ID: <1467224153-22873-1-git-send-email-fu.wei@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Fu Wei 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 (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 arm_arch_timer (4)Add GTDT support for ARM memory-mapped timer Changelog: v6: split the GTDT driver to 4 parts: basic, arch_timer, memory-mapped timer, and SBSA Generic Watchdog timer Improve driver by suggestions and example code from Daniel Lezcano v5: https://lkml.org/lkml/2016/5/24/356 Sorting out all patches, simplify the API of GTDT driver: GTDT driver just fills the data struct for arm_arch_timer driver. 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 Fu Wei (10): clocksource/drivers/arm_arch_timer: Move enums and defines to header file clocksource/drivers/arm_arch_timer: Add a new enum for spi type clocksource/drivers/arm_arch_timer: Improve printk relevant code acpi: Add some basic struct and functions in GTDT driver acpi: Add arch_timer support in GTDT table parse driver acpi: Add GTDT driver to kernel build system clocksource/drivers/arm_arch_timer: Simplify ACPI support code. acpi: Add memory-mapped timer support in GTDT driver clocksource/drivers/arm_arch_timer: Add GTDT support for memory-mapped timer acpi: Add SBSA Generic Watchdog support in GTDT driver drivers/acpi/Kconfig | 9 + drivers/acpi/Makefile | 1 + drivers/acpi/acpi_gtdt.c | 326 +++++++++++++++++++++++++++++++++++ drivers/clocksource/Kconfig | 1 + drivers/clocksource/arm_arch_timer.c | 227 +++++++++++++++++------- drivers/watchdog/Kconfig | 1 + include/clocksource/arm_arch_timer.h | 32 ++++ include/linux/acpi.h | 7 + 8 files changed, 538 insertions(+), 66 deletions(-) create mode 100644 drivers/acpi/acpi_gtdt.c -- 2.5.5
