[PATCH v4 0/5] Add support for Axis, ARTPEC-8 PCIe driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This v4 patchset is improvement several review comments received from patchset v3.

Main changes since v3 [3]:
dt-bindings: pci: Add ARTPEC-8 PCIe controller
-add missing properties

dt-bindings: phy: Add ARTPEC-8 PCIe phy
-add "fsys-sysreg" to properties
-modify the "lcpll-ref-clk" and "clocks" in properties
 "lcpll-ref-clk" is custom properties, so add 'vendor', type(enum),
 description
 Add the maxItem in clocks, add clock-names in properties

PCI: axis: Add ARTPEC-8 PCIe controller driver
-remove unnecessary enum type
-fix indentation

phy: Add ARTPEC-8 PCIe PHY driver
-modify to use GENMASK
-fix indentation
-remove the driver data

Main changes since v2 [2]:
dt-bindings: pci: Add ARTPEC-8 PCIe controller
-modify version history to fit the linux commit rule
-remove 'Device Tree Bindings' on title
-remove the interrupt-names, phy-names entries
-remove '_clk' suffix
-add the compatible entries on required
-change node name to soc from artpec8 on examples

dt-bindings: phy: Add ARTPEC-8 PCIe phy
-modify version history to fit the linux commit rule
-remove 'Device Tree Bindings' on title
-remove clock-names entries
-change node name to soc from artpec8 on excamples

PCI: axis: Add ARTPEC-8 PCIe controller driver
-add 'COMPILE_TEST' and improvement help on kconfig
-reorder obj on makefile
-use clk_bulk_api
-remove unnecessary comment
-redefine the ELBI register to distinguish between offset and
 bit definition
-improvement order local variable of function
-remove unnecessary local return variable

phy: Add ARTPEC-8 PCIe PHY driver
-remove unnecessary indentation
-redefine local struct to statis const
-add static const to struct that requires static const definition
-remove wrappers on writel and readl

Main changes since v1 [1]:
-'make dt_binding_check' result improvement
-Add the missing property list
-improvement review comment of Krzysztof on driver code
-change folder name of phy driver to axis from artpec

--------------------------------------------------------------
This series patches include newly PCIe support for Axis ARTPEC-8 SoC.
ARTPEC-8 is the SoC platform of Axis Communications.
PCIe controller driver and phy driver have been newly added.
There is also a new MAINTAINER in the addition of phy driver.
PCIe controller is designed based on Design-Ware PCIe controller IP
and PCIe phy is desinged based on SAMSUNG PHY IP.
It also includes modifications to the Design-Ware controller driver to 
run the 64bit-based ARTPEC-8 PCIe controller driver.
It consists of 6 patches in total.

This series has been tested on AXIS SW bring-up board 
with ARTPEC-8 chipset.
