From mboxrd@z Thu Jan 1 00:00:00 1970 From: Li Jun Subject: [PATCH v7 00/23] usb gadget update for OTG 2.0 Date: Thu, 9 Jul 2015 15:18:37 +0800 Message-ID: <1436426340-18477-1-git-send-email-jun.li@freescale.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-usb-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: gregkh-hQyY1W1yCW8ekmWlsbkhG0B+6BGkLq7r@public.gmane.org, balbi-l0cyMroinI0@public.gmane.org, peter.chen-KZfg59tc24xl57MIdRCFDg@public.gmane.org, robh+d-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org Cc: linux-usb-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, pawel.moll-5wv7dgnIgG8@public.gmane.org, mark.rutland-5wv7dgnIgG8@public.gmane.org, macpaul-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org, rogerq-l0cyMroinI0@public.gmane.org, Li Jun List-Id: devicetree@vger.kernel.org Change for v7: - Free otg descriptor when failure of bind in patch 21, 22, 23. add Roger's Reviewed-by for patch 10~20. - Choose the lesser otg-rev if otg-rev has been set before update by DT, remove 0x0300 in supported otg-rev list, and add code comments in case otg-rev is not passed in DT in patch 7. - Fail chipidea usb initilization if DT pass an unsupported otg-rev in patch 8. Change for v6: - Change of_usb_set_otg_caps to be of_usb_update_otg_caps, and add sanity check of otg-rev. - Add chipidea otg-rev ability to be 0x0200, which will be updated in DT, if not passed, will be reset to be 0. - Remove unnecessary change: move config's descriptor and bmAttributes init from xxxi_config() to xxx_bind() in leagcy gadget drivers. This is a follow-up of Macpaul Lin's previous patchset to resolve usb gadget driver working with OTG 2.0, and set otg features by not only usb driver config but also usb hardware property in DT, main changes: 1. Add usb_otg20_descriptor definition for OTG 2.0 which introduces bcdOTG field for otg revision, bcdOTG can be passed via device tree. 2. OTG features(SRP/HNP/ADP) can be decided by combination of usb HW properties and usb driver config. 3. Change the chipidea usb driver to use the updated mechanism. 4. Remove static usb otg descriptor definition, but allocate and init it according to otg capabilities in each gadget driver, if otg capabilities is not defined for legacy platforms, the usb otg descriptor content is kept the same as current static definition.
