From ea0d856cb26d4d78b9529de49a0f89379224e2f9 Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Fri, 20 May 2016 16:41:41 +1000 Subject: powerpc/powernv: Functions to get/set PCI slot state This exports 4 functions, which base on the corresponding OPAL APIs to get/set PCI slot status. Those functions are going to be used by PowerNV PCI hotplug driver: pnv_pci_get_device_tree() opal_get_device_tree() pnv_pci_get_presence_state() opal_pci_get_presence_state() pnv_pci_get_power_state() opal_pci_get_power_state() pnv_pci_set_power_state() opal_pci_set_power_state() Signed-off-by: Gavin Shan Reviewed-by: Alexey Kardashevskiy Signed-off-by: Michael Ellerman --- arch/powerpc/include/asm/opal-api.h | 18 +++++++++++++++++- 1 file changed, 17 insertions(+), 1 deletion(-) (limited to 'arch/powerpc/include/asm/opal-api.h') diff --git a/arch/powerpc/include/asm/opal-api.h b/arch/powerpc/include/asm/opal-api.h index cd9371b33f1a..72b5f27cd0b8 100644 --- a/arch/powerpc/include/asm/opal-api.h +++ b/arch/powerpc/include/asm/opal-api.h @@ -158,7 +158,11 @@ #define OPAL_LEDS_SET_INDICATOR 115 #define OPAL_CEC_REBOOT2 116 #define OPAL_CONSOLE_FLUSH 117 -#define OPAL_LAST 117 +#define OPAL_GET_DEVICE_TREE 118 +#define OPAL_PCI_GET_PRESENCE_STATE 119 +#define OPAL_PCI_GET_POWER_STATE 120 +#define OPAL_PCI_SET_POWER_STATE 121 +#define OPAL_LAST 121 /* Device tree flags */ @@ -344,6 +348,18 @@ enum OpalPciResetState { OPAL_ASSERT_RESET = 1 }; +enum OpalPciSlotPresence { + OPAL_PCI_SLOT_EMPTY = 0, + OPAL_PCI_SLOT_PRESENT = 1 +}; + +enum OpalPciSlotPower { + OPAL_PCI_SLOT_POWER_OFF = 0, + OPAL_PCI_SLOT_POWER_ON = 1, + OPAL_PCI_SLOT_OFFLINE = 2, + OPAL_PCI_SLOT_ONLINE = 3 +}; + enum OpalSlotLedType { OPAL_SLOT_LED_TYPE_ID = 0, /* IDENTIFY LED */ OPAL_SLOT_LED_TYPE_FAULT = 1, /* FAULT LED */ -- cgit
