7561dfbf - xtensa: drop platform_halt and platform_power_off

Wed, 07 Jun 2023 15:59:38 +0000

xtensa: drop platform_halt and platform_power_offInstead of using xtensa-specific platform_halt and platform_power_offcallbacks use do_kernel_power_off in the machine_halt andmachine_power_off and reimplement existing platform_halt andplatform_power_off users with register_sys_off_handler.Drop platform_halt and platform_power_off declarations and defaultimplementations.Signed-off-by: Max Filippov List of files: /linux-6.15/arch/xtensa/include/asm/platform.h

11976fe2 - xtensa: drop platform_restart

Wed, 07 Jun 2023 01:54:10 +0000

xtensa: drop platform_restartInstead of using xtensa-specific platform_restart callback usedo_kernel_restart in the machine_restart implementation and reimplementexisting platform_restart users with register_restart_handler.Drop platform_restart declaration and default implementation.Signed-off-by: Max Filippov List of files: /linux-6.15/arch/xtensa/include/asm/platform.h

71a5fd7d - xtensa: drop platform_heartbeat

Wed, 07 Jun 2023 00:43:47 +0000

xtensa: drop platform_heartbeatplatform_heartbeat is called from the timer interrupt handler, butthere may be no periodic timer interrupts on xtensa, so the frequency ofplatform_heartbeat calls may be unrelated to HZ. Drop the callback andreimplement its only user with a timer.Signed-off-by: Max Filippov List of files: /linux-6.15/arch/xtensa/include/asm/platform.h

0f665b9e - xtensa: use the generic uncached segment support

Tue, 29 Oct 2019 09:53:30 +0000

xtensa: use the generic uncached segment supportSwitch xtensa over to use the generic uncached support, and thus thegeneric implementations of dma_alloc_* and dma_alloc_*, which alsogains support for mmaping DMA memory. The non-working nommu DMAsupport has been disabled, but could be re-enabled easily if platformsthat actually have an uncached segment show up.Signed-off-by: Christoph Hellwig Reviewed-by: Max Filippov Tested-by: Max Filippov List of files: /linux-6.15/arch/xtensa/include/asm/platform.h

88804e68 - xtensa: drop dead PCI support code

Mon, 15 Oct 2018 19:33:51 +0000

xtensa: drop dead PCI support codextensa-specific PCI initialization code has significantly bitrotted overtime because there's no platform that use it. Get rid of remainingnon-functioning initialization and remove platform_pcibios_* interface.A new platform that would use PCI on xtensa will configure PCIcontroller using device tree.Drop variables pci_ctrl_head, pci_bus_count and functions pcibios_init,pci_controller_apertures, platform_pcibios_init andplatform_pcibios_fixup.Signed-off-by: Max Filippov List of files: /linux-6.15/arch/xtensa/include/asm/platform.h

2cc15e80 - xtensa: platform-specific handling of coherent memory

Wed, 11 Jul 2018 21:33:41 +0000

xtensa: platform-specific handling of coherent memoryMemory layout is not fixed for noMMU xtensa configurations. Platformsthat need to use coherent DMA should implement platform_vaddr_* helpersthat check address type (cached/uncached) and convert addresses betweenthese types.Signed-off-by: Max Filippov List of files: /linux-6.15/arch/xtensa/include/asm/platform.h

Wed, 04 Mar 2009 20:39:12 +0000

xtensa: remove platform rtc hooksplatform_get/set_rtc_time() is not implemented by any of the supportedxtensa platforms. Remove the facility completely.The initial seconds for xtime come from read_persistent_clock() whichreturns just 0 in the generic implementation. Platforms that sport apersistent clock can implement this function.This is needed to implement the ccount as a clock source.Signed-off-by: Johannes Weiner Signed-off-by: Chris Zankel List of files: /linux-6.15/arch/xtensa/include/asm/platform.h

xtensa: move headers files to arch/xtensa/includeMove all header files for xtensa to arch/xtensa/include and platform andvariant header files to the appropriate arch/xtensa/platforms/ andarch/xtensa/variants/ directories.Moving the files gets also rid of all uses of symlinks in the Makefile.This has been completed already for the majority of the architecturesand xtensa is one out of six missing.Signed-off-by: Sam Ravnborg Signed-off-by: Chris Zankel List of files: /linux-6.15/arch/xtensa/include/asm/platform.h
