Subject: [PATCH v5 0/2] PCI: Add new Unisoc PCIe driver
Date: Thu, 31 Dec 2020 18:18:23 +0800 [thread overview]
Message-ID: <1609409905-30721-1-git-send-email-wuht06@gmail.com> (raw)
From: Hongtao Wu <billows.wu@unisoc.com>
This series adds PCIe controller driver for Unisoc SoCs.
This controller is based on DesignWare PCIe IP.
Changes from v1:
1) Test this patch on top of Rob Herring's 40 part series of DWC clean-ups:
https://lore.kernel.org/linux-pci/20200821035420.380495-1-robh@kernel.org/
2) Delete empty function
3) Document property "sprd,pcie-poweron-syscons" and
'sprd,pcie-poweroff-syscons'
4) Delete runtime suspend/resume function
5) Add COMPILE_TEST which CONFIG_PCIE_SPRD depends on
Changes from v2:
1) Change RC mode to host mode in drivers/pci/controller/dwc/Kconfig
2) Change Signed-off-by from Billows Wu to Hongtao Wu
Changes from v3:
1) Split the property 'sprd,pcie-poweron-syscons' and
'sprd,pcie-poweroff-syscons' into reset, power domains, phy and so on.
2) Delete the function to get resource 'msi' and 'dbi' which were parsed by the
DW core.
3) Delete the function 'sprd_pcie_host_init', because the DW core has done it.
Changes from v4:
1) Install 'yamllint' and upgrade dt-schema in order to solve the yamllint and
dtschema/dtc warnings/errors.
