Subject: [PATCH v3 0/4] PCI: mvebu: Slot support
Date: Fri, 25 Mar 2022 10:38:23 +0100 [thread overview]
Message-ID: <20220325093827.4983-1-pali@kernel.org> (raw)
This patch series add slot support to pci-mvebu.c driver.
It is based on branch pci/mvebu of git repository:
https://git.kernel.org/pub/scm/linux/kernel/git/lpieralisi/pci.git
Changes in v3:
* Set 600 W when DT slot-power-limit-milliwatt > 600 W
Changes in v2:
* Dropped patch with PCI_EXP_SLTCAP_*_SHIFT macros as it is not needed anymore
* Dropped patch "ARM: dts: turris-omnia: Set PCIe slot-power-limit-milliwatt properties" which was applied
* Added support for PCIe 6.0 slot power limit encodings
* Round down slot power limit value
* Fix handling of slot power limit with scale x1.0 (0x00 value)
* Use FIELD_PREP instead of _SHIFT macros
* Changed commit message to Bjorn's suggestion
* Changed comments in the code to match PCIe spec
* Preserve user settings of PCI_EXP_SLTCTL_ASPL_DISABLE bit
Pali Rohár (4):
PCI: Add PCI_EXP_SLTCTL_ASPL_DISABLE macro
dt-bindings: Add 'slot-power-limit-milliwatt' PCIe port property
PCI: Add function for parsing 'slot-power-limit-milliwatt' DT property
PCI: mvebu: Add support for sending Set_Slot_Power_Limit message
