      ARM: dts: imx53-qsb: Allow usb peripheral mode to work · d39a5834
      由 Fabio Estevam 提交于 
      Trying to use the usb otg port on mx53qsb results in the following error:

$ modprobe g_ether
using random self ethernet address
using random host ethernet address
usb0: HOST MAC 52:0f:8a:1e:aa:09
usb0: MAC de:f3:70:d8:6c:62
using random self ethernet address
using random host ethernet address
g_ether gadget: Ethernet Gadget, version: Memorial Day 2008
g_ether gadget: g_ether ready

(Connect the USB cable)

$ ci_hdrc ci_hdrc.0: remove, state 4
usb usb1: USB disconnect, device number 1
ci_hdrc ci_hdrc.0: USB bus 1 deregistered
ci_hdrc ci_hdrc.0: timeout waiting for 00000800 in 11

USB otg port goes to connector J3 (mini USB) and also to the USB combo (J2).

As mx53qsb does not provide a USB ID pin, pass the dr_mode as 'peripheral' so
that we can have usb device working.

Tested via g_ether.

      pinctrl: imx: move hard-coding data into device tree · e1641531
      由 Shawn Guo 提交于 
      Currently, all imx pinctrl drivers maintain a big array of struct
imx_pin_reg which hard-codes data like register offset and mux mode
setting for each pin function.  Every time a new imx SoC support is
added, we need to add such a big mount of data.  With moving to single
kernel build, it's only matter of time to be blamed on memory consuming.

With DTC pre-processor support in place, the patch moves all these data
into device tree by redefining the PIN_FUNC_ID in imxXX-pinfunc.h and
changing the PIN_FUNC_ID parsing code a little bit.

The pin id gets re-numbered based on mux register offset, or config
register offset if the pin has no mux register, so that kernel can
identify the pin id from register offsets provided by device tree.

As a bonus point of the change, those arbitrary magic numbers standing
for particular PIN_FUNC_ID in device tree sources are now replaced by
macros to improve the readability of dts files.

      ARM: imx: use #include for all device trees · 36dffd8f
      由 Shawn Guo 提交于 
      Replace /include/ (dtc) with #include (C pre-processor) for all imx DT
files, so that gcc -E handles the entire include tree, and hence any of
those files can #include some other file e.g. for constant definitions.

This allows future use of #defines and header files in order to define
names for various constants, such as pinctrl settings. Use of those
features will increase the readability of the device tree files.
