Merge tag 'davinci-for-v5.1/soc-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci into arm/fixes
DaVinci SoC updates for v5.1 (part 2) This pull request contains changes needed to help get rid of hard-coded GPIO base value passed from DaVinci platform data. The OHCI related changes also help by moving over-current support from board-files to OHCI driver making future DT-coversion easy. The OHCI parts are acked by its maintainer. * tag 'davinci-for-v5.1/soc-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci: usb: ohci-da8xx: remove unused callbacks from platform data ARM: davinci: da830-evm: remove legacy usb helpers ARM: davinci: omapl138-hawk: remove legacy usb helpers usb: ohci-da8xx: add vbus and overcurrent gpios ARM: davinci: da830-evm: use gpio lookup entries for usb gpios ARM: davinci: omapl138-hawk: use gpio lookup entries for usb gpios usb: ohci-da8xx: add a helper pointer to &pdev->dev usb: ohci-da8xx: add a new line after local variables ARM: davinci: da850-evm: use GPIO hogs instead of the legacy API ARM: davinci: mityomapl138: use device properties for at24 eeprom ARM: davinci: mityomapl138: use nvmem notifiers ARM: davinci: remove dead code related to MAC address reading ARM: davinci: sffsdr: use device properties for at24 eeprom ARM: davinci: sffsdr: fix the at24 eeprom device name ARM: davinci: dm646x-evm: use device properties for at24 eeprom ARM: davinci: dm644x-evm: use device properties for at24 eeprom ARM: davinci: da830-evm: use device properties for at24 eeprom ARM: davinci: dm365-evm: use device properties for at24 eeprom ARM: davinci: mityomapl138: don't read the MAC address from machine code ARM: davinci: da850-evm: remove dead MTD code Signed-off-by: Arnd Bergmann <arnd@arndb.de>
