Everyone: This is the series containing various small improvements that I made while reading the code and researching commit history of pci-imx6.c and pcie-designware*.c files. All changes are optional, so commits that don't seem like an improvement can be easily dropped. Hopefully each patch is self-explanatory. I tested this series on i.MX6Q, i.MX7D and i.MX8MQ. Feedback is welcome! Thanks, Andrey Smirnov Changes since [v1]: - Dropped "PCI: imx6: Drop imx6_pcie_link_up()" due to the matter already having been addressed by "PCI: imx6: Fix link training status detection in link up check" from Trent Piepho - Changed "designware" -> "dwc" for all subject lines - Collected Acked-by's from Gustavo Pimentel [v1] lkml.kernel.org/r/20181221072716.29017-1-andrew.smirnov@xxxxxxxxx Andrey Smirnov (20): PCI: imx6: Simplify imx7d_pcie_wait_for_phy_pll_lock() PCI: imx6: Remove redundant debug tracing PCI: imx6: Return -ETIMEOUT from imx6_pcie_wait_for_speed_change() PCI: imx6: Remove duplicate macro definitions PCI: imx6: Remove PCIE_PL_PFLR_* constants PCI: imx6: Remove PCIE_PHY_RX_ASIC_OUT* constants PCI: dwc: Make use of IS_ALIGNED() PCI: dwc: Share code for dw_pcie_rd/wr_other_conf() PCI: dwc: imx6: Share PHY debug register definitions PCI: dwc: Make use of BIT() in constant definitions PCI: imx6: Make use of BIT() in constant definitions PCI: imx6: Simplify bit operations in PHY functions PCI: imx6: Simplify pcie_phy_poll_ack() PCI: imx6: Restrict PHY register data to 16-bit PCI: imx6: Pass data to dw_pcie_writel_dbi() directly PCI: imx6: Use common mask in imx6_pcie_reset_phy() PCI: imx6: Simplify bit operations in imx6_setup_phy_mpll() PCI: imx6: Remove magic numbers from imx6_pcie_establish_link() PCI: dwc: Make use of GENMASK/FIELD_PREP PCI: dwc: Remove superfluous shifting in definitions drivers/pci/controller/dwc/pci-imx6.c | 139 +++++++----------- .../pci/controller/dwc/pcie-designware-host.c | 61 +++----- drivers/pci/controller/dwc/pcie-designware.c | 18 +-- drivers/pci/controller/dwc/pcie-designware.h | 60 ++++---- 4 files changed, 115 insertions(+), 163 deletions(-) -- 2.20.1
