      powerpc/85xx: Add local_irq_restore in error handling code · 870029a6
      由 Julia Lawall 提交于 
      There is a call to local_irq_restore in the normal exit case, so it would
seem that there should be one on an error return as well.

The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>

expression l;
expression E,E1,E2;

      powerpc/86xx: Update 8641hpcn dts file to match latest u-boot · 47f80a32
      由 Becky Bruce 提交于 
      The newest revision of uboot reworks the memory map for this
board to look more like the 85xx boards.  Also, some regions
which were far larger than the actual hardware have been scaled
back to match the board, and the imaginary second flash bank has
been removed. Rapidio and PCI are mutually exclusive in the hardware,
and they now are occupying the same space in the address map.
The Rapidio node is commented out of the .dts since PCI is the
common use case.

- Add gpio-controller node for BCSR13 bank (GPIOs on that bank
  are used to control the USB transceiver);
- Set up other BCSR registers;
- Configure the QE Par IO.

The work is loosely based on Li Yang's patch[1], which was used
to support peripheral mode only.

      powerpc: Implement GPIO driver for simple memory-mapped banks · 3d64de9c
      由 Anton Vorontsov 提交于 
      The driver supports very simple GPIO controllers, that is, when a
controller provides just a 'data' register. Such controllers may be
found in various BCSRs (Board's FPGAs used to control board's
switches, LEDs, chip-selects, Ethernet/USB PHY power, etc).

So far we support only 1-byte GPIO banks. Support for other widths may
be implemented when/if needed.

p.s.
To avoid "made up" compatible entries (like compatible = "simple-gpio"),
boards must call simple_gpiochip_init() to pass the compatible string.

      powerpc/qe: Implement QE Pin Multiplexing API · 1b9e8904
      由 Anton Vorontsov 提交于 
      With this API we're able to set a QE pin to the GPIO mode or a dedicated
peripheral function.

The API relies on the fact that QE gpio controllers are registered. If
they aren't, the API won't work (gracefully though).

There is one caveat though: if anybody occupied the node->data before us,
or overwrote it, then bad things will happen. Luckily this is all in the
platform code that we fully control, so this should never happen.

I could implement more checks (for example we could create a list of
successfully registered QE controllers, and compare the node->data in the
qe_pin_request()), but this is unneeded if nobody is going to do silly
things behind our back.
