Subject: [PATCH v2 0/6] Add SiFive FU740 PCIe host controller driver support
Date: Thu, 18 Mar 2021 14:08:07 +0800	[thread overview]
Message-ID: <cover.1615954045.git.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 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
