refer to the discussion [1] when try to enable i.MX8MM PCIe support, one standalone PCIe PHY driver should be seperated from i.MX PCIe driver when enable i.MX8MM PCIe support. This patch-set adds the standalone PCIe PHY driver suport[1-5], and i.MX8MM PCIe support[6-9] to have whole view to review this patch-set. The PCIe works on i.MX8MM EVK board based the the blkctrl power driver [2] and this PHY driver patch-set.
Whole series: Tested-by: Marcel Ziswiler <redacted> BTW: I tested it on Verdin iMX8M Mini V1.1B without an external PCIe oscillator aka setting fsl,refclk-pad-mode to IMX8_PCIE_REFCLK_PAD_OUTPUT which worked like a charm. Thanks!
[1] https://patchwork.ozlabs.org/project/linux-pci/patch/20210510141509.929120-3-l.stach@pengutronix.de/ [2] https://patchwork.kernel.org/project/linux-arm-kernel/cover/20210910202640.980366-1-l.stach@pengutronix.de/ Main changes v2 --> v3: - Regarding Lucas' comments. - to have a whole view to review the patches, send out the i.MX8MM PCIe support too. - move the PHY related bits manipulations of the GPR/SRC to standalone PHY driver. - split the dts changes to SOC and board DT, and use the enum instead of raw value. - update the license of the dt-binding header file. Changes v1 --> v2: - Update the license of the dt-binding header file to make the license compatible with dts files. - Fix the dt_binding_check errors.
