Hi Felipe, > Presented patch series fix several problems with S3C-HSOTG driver, > thus now the Multi Function Gadget (MFG) is working correctly. > > Those commits consist of EP0 transfer management fixes (ZLP sending > code and NAK management). > Moreover the disconnect irq handler has been removed, since it is > available only at HOST mode. > > Code for recovering from device disconnection and connection during > ongoing transfer has been added as well. > > The s3c-hsotg driver has been adjusted to use newer usb_gadget_ops > callbacks (namely udc_start and udc_stop) instead of deprecated ones. > > Moreover number of EPs is now read from a HW configuration register > instead of statically defined value. > > The our_hsotg global variable has been removed and release function > has been added as well to prevent warning messages. > > > --- > Changes for v2: > - Support for regulator_bulk_* > - Number of EPs determined during runtime > - Usage of udc_start and udc_stop methods instead of deprecated ones > - Code preparation to move to dwc2 driver from s3c-hsotg > > Changes for v3: > - Comments refactored to comply with kernel coding style > - Doxygen functions descriptions added > - Removal of our_hsotg global pointer variable > > Changes for v4: > - Remove platform dependent code > - Check if dynamically read number of EPs is not equal to zero > - Release function added to prevent warnings > > Changes for v5: > - Remove S3C_ prefix for register's definition > - Replace the clk_enable() with clk_prepare_enable() and > clk_disable() with clk_disable_unprepare() > - error fallback code for failed request_irq > > Lukasz Majewski (18): > usb:hsotg:samsung: Remove platform dependency from s3c-hsotg > usb:hsotg:samsung: Remove platform dependent functions from > s3c-hsotg usb:hsotg:samsung: Wrappers for USB PHY methods > usb:hsotg:samsung: Use of regulator_bulk_* functions for USB > regulators > usb:hsotg:samsung: NAK management for EP0 (Setup stage of control > transfers) > usb:hsotg:samsung: Sending ZLP packet for IN EP0 transfers > usb:hsotg:samsung: Extract core initialization function > usb:hsotg:samsung: Remove Disconnect Interrupt handler > usb:hsotg:samsung: Rename s3c_hsotg_disconnect function > usb:hsotg:samsung: Cable disconnection recovery code > usb:hsotg:samsung: Determine number of EPs from HW configuration > register > usb:hsotg:samsung: Use new udc_start and udc_stop callbacks > usb:hsotg:samsung: Comments reorganization and cleanup > usb:hsotg:samsung: Remove our_hsotg global pointer > usb:hsotg:samsung: Add release function for hsotg device > usb:hsotg:samsung: Remove the S3C_ prefix from registers definition. > usb:hsotg:samsung: Use clk_prepare_enable and clk_disable_unprepare > usb:hsotg:samsung: err_irq: support for probe function Do you have any comments to those patches? Are those suitable for for-next? -- Best regards, Lukasz Majewski Samsung Poland R&D Center Platform Group -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
