In this 5th iteration, the series was rebased on Linux 6.9-rc1. The PHY patches were moved to a dedicated series. The patch for the pinctrl-single driver was removed, as it was already applied to the pinctrl tree. Regards, Thomas Signed-off-by: Thomas Richard --- Changes in v5: - all: series rebased on Linux 6.9-rc1 - pinctrl-single: patch removed (already applied to the pinctrl tree) - phy: patches moved to a dedicated series. - pci: add T_PERST_CLK_US macro. - pci-j721e: update the comments about T_PERST_CLK_US. - Link to v4: https://lore.kernel.org/r/20240102-j7200-pcie-s2r-v4-0-6f1f53390c85@bootlin.com Changes in v4: - all: use SoB/Co-developed-by for patches initially developed by Théo Lebrun. - pinctrl-single: squash the two commits. - i2c-omap: fix line lenghts of the comment in omap_i2c_suspend(). - mux: mux_chip_resume() return 0 or at the first error. - phy-j721e-wiz: clean code around dev_err_probe(). - phy-j721e-wiz: use REF_CLK_100MHZ macros. - pci: fix subject line for all PCI patches. - pci-cadence: use fsleep() instead of usleep_range(). - pci-cadence: remove cdns_torrent_clk_cleanup() call in cdns_torrent_phy_resume_noirq(). - pci-j721e: add a patch to use dev_err_probe() instead of dev_err() in the probe(). - pci-j721e: fix unordered header files. - pci-j721e: remove some log spammers. - pci-j721e: add a missing clock disable in j721e_pcie_resume_noirq(). - pci-j721e: simplify the patch "Add reset GPIO to struct j721e_pcie" - Link to v3: https://lore.kernel.org/r/20240102-j7200-pcie-s2r-v3-0-5c2e4a3fac1f@bootlin.com Changes in v3: - pinctrl-single: split patch in two parts, a first patch to remove the dead code, a second to move suspend()/resume() callbacks to noirq. - i2c-omap: add a comments above the suspend_noirq() callback. - mux: now mux_chip_resume() try to restores all muxes, then return 0 if all is ok or the first failure. - mmio: fix commit message. - phy-j721e-wiz: add a patch to use dev_err_probe() instead of dev_err() in the wiz_clock_init() function. - phy-j721e-wiz: remove probe boolean for the wiz_clock_init(), rename the function to wiz_clock_probe(), extract hardware configuration part in a new function wiz_clock_init(). - phy-cadence-torrent: use dev_err_probe() and fix commit messages - pcie-cadence-host: remove probe boolean for the cdns_pcie_host_setup() function and extract the link setup part in a new function cdns_pcie_host_link_setup(). - pcie-cadence-host: make cdns_pcie_host_init() global. - pci-j721e: use the cdns_pcie_host_link_setup() cdns_pcie_host_init() functions in the resume_noirq() callback. - Link to v2: https://lore.kernel.org/r/20240102-j7200-pcie-s2r-v2-0-8e4f7d228ec2@bootlin.com Changes in v2: - all: fix commits messages. - all: use DEFINE_NOIRQ_DEV_PM_OPS and pm_sleep_ptr macros. - all: remove useless #ifdef CONFIG_PM. - pinctrl-single: drop dead code - mux: add mux_chip_resume() function in mux core. - mmio: resume sequence is now a call to mux_chip_resume(). - phy-cadence-torrent: fix typo in resume sequence (reset_control_assert() instead of reset_control_put()). - phy-cadence-torrent: use PHY instead of phy. - pci-j721e: do not shadow cdns_pcie_host_setup return code in resume sequence. - pci-j721e: drop dead code. - Link to v1: https://lore.kernel.org/r/20240102-j7200-pcie-s2r-v1-0-84e55da52400@bootlin.com --- Thomas Richard (8): gpio: pca953x: move suspend()/resume() to suspend_noirq()/resume_noirq() i2c: omap: wakeup the controller during suspend() callback mux: add mux_chip_resume() function PCI: cadence: Extract link setup sequence from cdns_pcie_host_setup() PCI: cadence: Set cdns_pcie_host_init() global PCI: j721e: Use dev_err_probe() in the probe() function PCI: Add T_PERST_CLK_US macro PCI: j721e: Use T_PERST_CLK_US macro Théo Lebrun (3): mux: mmio: add resume support PCI: j721e: Add reset GPIO to struct j721e_pcie PCI: j721e: Add suspend and resume support drivers/gpio/gpio-pca953x.c | 7 +- drivers/i2c/busses/i2c-omap.c | 22 ++++ drivers/mux/core.c | 29 +++++ drivers/mux/mmio.c | 12 ++ drivers/pci/controller/cadence/pci-j721e.c | 121 ++++++++++++++++++--- drivers/pci/controller/cadence/pcie-cadence-host.c | 44 +++++--- drivers/pci/controller/cadence/pcie-cadence.h | 12 ++ drivers/pci/pci.h | 3 + include/linux/mux/driver.h | 1 + 9 files changed, 214 insertions(+), 37 deletions(-) --- base-commit: 3d31103a742d8c94924848dc0fb5e2ce6b701932 change-id: 20240102-j7200-pcie-s2r-ecb1a979e357 Best regards,
