Signed-off-by: Joao Pinto --- Changes v6->v7 (Arnd Bergmann): - Changed DT node name (to ufs only) and the memory address (to 0xd000000) - Removed CONFIG_PM from the PCI glue driver (pm.h already does this) - No other changes are necessary in ufshcd.c because of the link up notify function usage (it is simpler now) - Removed the PHY mentioning since the Test Chip is not a real PHY for real world usage, since it is a test chip for prototyping with a very specific usage - Added again the Test Chip 20-bit option Changes v5->v6: - Patch bad format fixed Changes v4->v5 (Akinobu Mita): - All functions used only locally in ufshcd-dwc are now declared as static - ufshcd_dwc_configuration() was removed in ufshcd-dwc and a notify function (ufshcd_dwc_link_startup_notify) was created to deal with the DWC specific init routines - 20-bit RMMI option was removed from Kconfig. Now if MPHY TC is selected and 40-bit is not then it assumes a 20-bit config Changes v3->v4 (Arnd Bergmann and Mark Rutland): - SCSI_UFS_DWC_HOOKS is now silent and selected by the SCSI_UFS_DWC_PLAT or SCSI_UFS_DWC_PCI - Compatibility string has the ufs core version for info purposes since the driver is capable of getting the controller version from its registers - Created ufs-dwc-pci glue driver with specific DWC data - MPHY configuration remains in the ufshcd-dwc since it is unipro attribute writting only not following the a linux phy framework logic Changes v2->v3 (Julian Calaby): - Implement a common DWC code to be used by the platform and pci glue drivers - Synopsys ID & Class added to the existing pci driver and specific DWC was also added to the pci driver Changes v1->v2 (Akinobu Mita): - Implement a platform driver that uses the existing UFS core driver - Add DWC specific code to the existing UFS core driver Documentation/devicetree/bindings/ufs/ufs-dwc.txt | 17 + MAINTAINERS | 6 + drivers/scsi/ufs/Kconfig | 51 ++ drivers/scsi/ufs/Makefile | 3 + drivers/scsi/ufs/ufs-dwc-pci.c | 172 +++++ drivers/scsi/ufs/ufs-dwc.c | 102 +++ drivers/scsi/ufs/ufshcd-dwc.c | 739 ++++++++++++++++++++++ drivers/scsi/ufs/ufshcd-dwc.h | 18 + drivers/scsi/ufs/ufshci-dwc.h | 42 ++ drivers/scsi/ufs/unipro.h | 39 ++ 10 files changed, 1189 insertions(+) create mode 100644 Documentation/devicetree/bindings/ufs/ufs-dwc.txt create mode 100644 drivers/scsi/ufs/ufs-dwc-pci.c create mode 100644 drivers/scsi/ufs/ufs-dwc.c create mode 100644 drivers/scsi/ufs/ufshcd-dwc.c create mode 100644 drivers/scsi/ufs/ufshcd-dwc.h create mode 100644 drivers/scsi/ufs/ufshci-dwc.h diff --git a/Documentation/devicetree/bindings/ufs/ufs-dwc.txt b/Documentation/devicetree/bindings/ufs/ufs-dwc.txt new file mode 100644 index 0000000..3cbfd77 --- /dev/null +++ b/Documentation/devicetree/bindings/ufs/ufs-dwc.txt @@ -0,0 +1,17 @@ +* Universal Flash Storage (UFS) DesignWare Host Controller + +DWC_UFSHC nodes are defined to describe on-chip UFS host controllers. +Each UFS controller instance should have its own node. + +Required properties: +- compatible : compatible string ("snps,ufshcd-1.0", "snps,ufshcd-1.1" + or "snps,ufshcd-2.0") +- reg : +- interrupts : + +Example: + ufs@0xd0000000 { + compatible = "snps,ufshcd-2.0"; + reg = < 0xd0000000 0x10000 >; + interrupts = < 24 >; + }; diff --git a/MAINTAINERS b/MAINTAINERS index d2f94e2..3db3c4c 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -11006,6 +11006,12 @@ S: Supported F: Documentation/scsi/ufs.txt F: drivers/scsi/ufs/ +UNIVERSAL FLASH STORAGE HOST CONTROLLER DRIVER DWC HOOKS +M: Joao Pinto +L: linux-scsi@vger.kernel.org +S: Supported +F: drivers/scsi/ufs/*dwc* + UNSORTED BLOCK IMAGES (UBI) M: Artem Bityutskiy M: Richard Weinberger diff --git a/drivers/scsi/ufs/Kconfig b/drivers/scsi/ufs/Kconfig index 5f45307..35e9ddf 100644 --- a/drivers/scsi/ufs/Kconfig +++ b/drivers/scsi/ufs/Kconfig @@ -83,3 +83,54 @@ config SCSI_UFS_QCOM Select this if you have UFS controller on QCOM chipset.
