Subject: [PATCH v7 0/3] PCI: IPQ6018 platform support
Date: Sun, 12 Jun 2022 13:18:32 +0300	[thread overview]
Message-ID: <cover.1655028401.git.baruch@tkos.co.il> (raw)

This series adds support for the single PCIe lane on IPQ6018 SoCs. The code is 
ported from downstream Codeaurora v5.4 kernel. The main difference from 
downstream code is the split of PCIe registers configuration from .init to 
.post_init, since it requires phy_power_on().

Tested on IPQ6010 based hardware.

Changes in v7:

  * Use FIELD_PREP for power limit and scale fields

  * Add Stanimir Varbanov to Cc

  * Rebase on v5.19-rc1

Changes in v6:

  * Drop DT patch applied to the qcom tree

  * Normalize driver changes subject line

  * Add a preparatory patch to rename PCIE_CAP_LINK1_VAL to PCIE_CAP_SLOT_VAL,
    and define it using PCI_EXP_SLTCAP_* macros

  * Drop a vague comment about ASPM configuration

  * Add a comment about the source of delay periods

Changes in v5:

  * Remove comments from qcom_pcie_init_2_9_0() (Bjorn Andersson)

Changes in v4:

  * Drop applied DT bits

  * Add max-link-speed that was missing from the applied v2 patch

  * Rebase the driver on v5.16-rc3

Changes in v3:

  * Drop applied patches

  * Rely on generic code for speed setup

  * Drop unused macros

  * Formatting fixes

Changes in v2:

  * Add patch moving GEN3_RELATED macros to a common header

  * Drop ATU configuration from pcie-qcom

  * Remove local definition of common registers

  * Use bulk clk and reset APIs

  * Remove msi-parent from device-tree
