usb: chipidea: debug: check before accessing ci_role

2017-06-14T13:05:59Z

commit 0340ff83cd4475261e7474033a381bc125b45244 upstream. ci_role BUGs when the role is >= CI_ROLE_END. Signed-off-by: Michael Thalmeier Signed-off-by: Peter Chen Signed-off-by: Greg Kroah-Hartman

chipidea: error on overflow for port_test_write

2016-02-21T04:15:57Z

The write value is 8bit, but currently writing a larger number (eg a doubled digit) is not errored but instead gets cast and sets off an action probably undesired. Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

usb: chipidea: debug: use list_for_each_entry

2016-01-25T04:55:33Z

Use list_for_each_entry() instead of list_for_each() to simplify the code. Signed-off-by: Geliang Tang Signed-off-by: Greg Kroah-Hartman

usb: chipidea: support debugfs without CONFIG_USB_CHIPIDEA_DEBUG

2015-12-24T06:15:26Z

Since we need to mount debugfs to show/store the things we want to debug, it is duplicated to add another configuration to enable it. Meanwhile, with CONFIG_USB_CHIPIDEA_DEBUG, we can't support chipidea debugfs at runtime. Signed-off-by: Peter Chen Cc: Jun Li

usb: chipidea: debug: disable usb irq while role switch

2015-11-18T06:07:54Z

Since the ci->role will be set after the host role start is complete, there will be nobody cared irq during start host if usb irq enabled. This error can be reproduced on i.mx6 sololite EVK board by: 1. disable otg id irq(IDIE) and disable all real otg properties of usbotg1 in dts. 2. boot up the board with ID cable and usb device connected. 3. echo gadget > /sys/kernel/debug/ci_hdrc.0/role 4. echo host > /sys/kernel/debug/ci_hdrc.0/role 5. irq 212: nobody cared.

Merge tag 'usb-ci-v4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/peter.chen/usb into usb-next

2015-08-14T23:43:09Z

Peter writes: USB: chipidea updates for v4.3-rc1 The main changes are adding several system interfaces for tuning performance, and each vendors can adjust them according to their design configurations. Others are tiny improvements, like more well siTD supports, USB_DEVICE_A_HNP_SUPPORT supports, etc.

usb: chipidea: debug: add runtime pm for register access

2015-08-14T01:13:12Z

Add runtime pm operations for registers access to avoid system hang. Signed-off-by: Li Jun

usb: chipidea: update ci_otg_is_fsm_mode conditions

2015-07-29T14:59:21Z

After introduce usb otg properties, update ci_otg_is_fsm_mode conditions to be depending on both usb hardware properties and usb driver config, also resolve a compile issue in debug.c after the API change. Acked-by: Peter Chen Signed-off-by: Li Jun Signed-off-by: Felipe Balbi

usb: chipidea: debug: avoid out of bound read

2015-05-06T06:28:18Z

A string written by the user may not be zero terminated. sscanf may read memory beyond the buffer if no zero byte is found. For testing build with CONFIG_USB_CHIPIDEA=y, CONFIG_USB_CHIPIDEA_DEBUG=y. Signed-off-by: Heinrich Schuchardt Signed-off-by: Peter Chen

usb: chipidea: debug: add low power mode check before print registers

2015-04-08T06:32:00Z

Since the required clock to access registers is gated off in low power mode, add ci->in_lpm check before try to dump registers value. Signed-off-by: Li Jun Signed-off-by: Peter Chen
