Subject: [PATCH v5 0/6] Add SiFive FU740 PCIe host controller driver support
Date: Tue, 6 Apr 2021 17:26:28 +0800 [thread overview]
Message-ID: <20210406092634.50465-1-greentime.hu@sifive.com> (raw)
This patchset includes SiFive FU740 PCIe host controller driver. We also
add pcie_aux clock and pcie_power_on_reset controller to prci driver for
PCIe driver to use it.
This is tested with e1000e: Intel(R) PRO/1000 Network Card, AMD Radeon R5
230 graphics card and SP M.2 PCIe Gen 3 SSD in SiFive Unmatched based on
v5.11 Linux kernel.
Changes in v5:
- Fix typo in comments
- Keep comments style consistent
- Refine some error handling codes
- Remove unneeded header file including
- Merge fu740_pcie_ltssm_enable implementation to fu740_pcie_start_link
Changes in v4:
- Fix Wunused-but-set-variable warning in prci driver
Changes in v3:
- Remove items that has been defined
- Refine format of sifive,fu740-pcie.yaml
- Replace perstn-gpios with the common one
- Change DBI mapping space to 2GB from 4GB
- Refine drivers/reset/Kconfig
Changes in v2:
- Refine codes based on reviewers' feedback
- Remove define and use the common one
- Replace __raw_writel with writel_relaxed
- Split fu740_phyregreadwrite to write function
- Use readl_poll_timeout in stead of while loop checking
- Use dwc common codes
- Use gpio descriptors and the gpiod_* api.
- Replace devm_ioremap_resource with devm_platform_ioremap_resource_byname
- Replace devm_reset_control_get with devm_reset_control_get_exclusive
- Add more comments for delay and sleep
- Remove "phy ? x : y" expressions
- Refine code logic to remove possible infinite loop
- Replace magic number with meaningful define
- Remove fu740_pcie_pm_ops
- Use builtin_platform_driver
