ACPI / EC: Fix regression related to PM ops support in ECDT device

2017-11-20T23:13:02Z

On platforms (ASUS X550ZE and possibly all ASUS X series) with valid ECDT EC but invalid DSDT EC, EC PM ops won't be invoked as ECDT EC is not an ACPI device. Thus the following commit actually removed post-resume acpi_ec_enable_event() invocation for such platforms, and triggered a regression on them that after being resumed, EC (actually should be ECDT) driver stops handling EC events: Commit: c2b46d679b30c5c0d7eb47a21085943242bdd8dc Subject: ACPI / EC: Add PM operations to improve event handling for resume process Notice that the root cause actually is "ECDT is not an ACPI device" rather than "the timing of acpi_ec_enable_event() invocation", this patch fixes this issue by enumerating ECDT EC as an ACPI device. Due to the existence of the noirq stage, the ability of tuning the timing of acpi_ec_enable_event() invocation is still meaningful. This patch is a little bit different from the posted fix by moving acpi_config_boot_ec() from acpi_ec_ecdt_start() to acpi_ec_add() to make sure that EC event handling won't be stopped as long as the ACPI EC driver is bound. Thus the following sequence shouldn't disable EC event handling: unbind,suspend,resume,bind.

Pull ACPI updates from Rafael Wysocki: "These update ACPICA to upstream revision 20170831, fix APEI to use the fixmap instead of ioremap_page_range(), add an operation region driver for TI PMIC TPS68470, add support for PCC subspace IDs to the ACPI CPPC driver, fix a few assorted issues and clean up some code. Specifics: - Update the ACPICA code to upstream revision 20170831 including * PDTT table header support (Bob Moore). * Cleanup and extension of internal string-to-integer conversion functions (Bob Moore). * Support for 64-bit hardware accesses (Lv Zheng). * ACPI PM Timer code adjustment to deal with 64-bit return values of acpi_hw_read() (Bob Moore). * Support for deferred table verification in acpiexec (Lv Zheng). - Fix APEI to use the fixmap instead of ioremap_page_range() which cannot work correctly the way the code in there attempted to use it and drop some code that's not necessary any more after that change (James Morse). - Clean up the APEI support code and make it use 64-bit timestamps (Arnd Bergmann, Dongjiu Geng, Jan Beulich). - Add operation region driver for TI PMIC TPS68470 (Rajmohan Mani). - Add support for PCC subspace IDs to the ACPI CPPC driver (George Cherian). - Fix an ACPI EC driver regression related to the handling of EC events during the "noirq" phases of system suspend/resume (Lv Zheng). - Delay the initialization of the lid state in the ACPI button driver to fix issues appearing on some systems (Hans de Goede). - Extend the KIOX000A "device always present" quirk to cover all affected BIOS versions (Hans de Goede). - Clean up some code in the ACPI core and drivers (Colin Ian King, Gustavo Silva)" * tag 'acpi-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (24 commits) ACPI: Mark expected switch fall-throughs ACPI / LPSS: Remove redundant initialization of clk ACPI / CPPC: Make CPPC ACPI driver aware of PCC subspace IDs mailbox: PCC: Move the MAX_PCC_SUBSPACES definition to header file ACPI / sysfs: Make function param_set_trace_method_name() static ACPI / button: Delay acpi_lid_initialize_state() until first user space open ACPI / EC: Fix regression related to triggering source of EC event handling APEI / ERST: use 64-bit timestamps ACPI / APEI: Remove arch_apei_flush_tlb_one() arm64: mm: Remove arch_apei_flush_tlb_one() ACPI / APEI: Remove ghes_ioremap_area ACPI / APEI: Replace ioremap_page_range() with fixmap ACPI / APEI: remove the unused dead-code for SEA/NMI notification type ACPI / x86: Extend KIOX000A quirk to cover all affected BIOS versions ACPI / APEI: adjust a local variable type in ghes_ioremap_pfn_irq() ACPICA: Update version to 20170831 ACPICA: Update acpi_get_timer for 64-bit interface to acpi_hw_read ACPICA: String conversions: Update to add new behaviors ACPICA: String conversions: Cleanup/format comments.
