MIPS: SGI-IP30: Fix platform-device leak in bridge_platform_create()

2022-09-19T14:32:54Z

In error case in bridge_platform_create after calling platform_device_add()/platform_device_add_data()/ platform_device_add_resources(), release the failed 'pdev' or it will be leak, call platform_device_put() to fix this problem. Besides, 'pdev' is divided into 'pdev_wd' and 'pdev_bd', use platform_device_unregister() to release sgi_w1 resources when xtalk-bridge registration fails.

MIPS: SGI-IP30: Free some unused memory

2022-04-26T13:07:23Z

platform_device_add_data() duplicates the memory it is passed. So we can free some memory to save a few bytes that would remain unused otherwise. Signed-off-by: Christophe JAILLET Signed-off-by: Thomas Bogendoerfer

memblock: rename memblock_free to memblock_phys_free

2021-11-06T20:30:41Z

Since memblock_free() operates on a physical range, make its name reflect it and rename it to memblock_phys_free(), so it will be a logical counterpart to memblock_phys_alloc(). The callers are updated with the below semantic patch: @@ expression addr; expression size; @@ - memblock_free(addr, size); + memblock_phys_free(addr, size); Link: https://lkml.kernel.org/r/20210930185031.18648-6-rppt@kernel.org Signed-off-by: Mike Rapoport Cc: Christophe Leroy Cc: Juergen Gross Cc: Shahab Vahedi Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

mips: Bulk conversion to generic_handle_domain_irq()

2021-08-12T10:39:40Z

Wherever possible, replace constructs that match either generic_handle_irq(irq_find_mapping()) or generic_handle_irq(irq_linear_revmap()) to a single call to generic_handle_domain_irq(). Acked-by: Thomas Bogendoerfer Signed-off-by: Marc Zyngier

MIPS: Add missing linux/irqdomain.h includes

2021-06-10T12:09:16Z

A number of MIPS platforms are failing to directly include irqdomain.h. Fix this so that we can drop unnecessary dependencies Signed-off-by: Marc Zyngier

MIPS: SGI-IP30: Move irq bits to better header files

2020-09-21T20:15:49Z

Move HEART specific parts of mach-ip30/irq.h to asm/sgi/heart.h and IP30 specific parts to sgi-ip30/ip30-common.h. Signed-off-by: Thomas Bogendoerfer

MIPS: Only include the platform file needed

2020-05-12T22:17:18Z

Instead of including all Platform files, we simply include the needed one and avoid clashes with makefile variables. Signed-off-by: Thomas Bogendoerfer
