powerpc/QE: move QE_GPIO Kconfig symbol into the platforms/Kconfig

2008-10-13T16:09:58+00:00

Specifying user-selectable option in the qe_lib/Kconfig was a bad idea
because the qe_lib/Kconfig is included into the top level Kconfig, and
thus the QE_GPIO option appears at the top level menu.

This patch effectively moves the QE_GPIO option under the platform menu
instead.

powerpc: fix memory leaks in QE library

2008-08-21T04:58:12+00:00

Fix two memory leaks in the Freescale QE library: add a missing kfree() in
ucc_fast_init() and ucc_slow_init() if the ioremap() fails, and update
ucc_fast_free() and ucc_slow_free() to call iounmap() if necessary.

Based on a patch from Tony Breeds .

gpiolib: allow user-selection

2008-07-25T17:53:30+00:00

This patch adds functionality to the gpio-lib subsystem to make it
possible to enable the gpio-lib code even if the architecture code didn't
request to get it built in.

The archtitecture code does still need to implement the gpiolib accessor
functions in its asm/gpio.h file.  This patch adds the implementations for
x86 and PPC.

With these changes it is possible to run generic GPIO expansion cards on
every architecture that implements the trivial wrapper functions.  Support
for more architectures can easily be added.

powerpc: Fix a bunch of sparse warnings in the qe_lib

2008-07-16T22:57:45+00:00

Mostly having to do with not marking things __iomem.  And some failure
to use appropriate accessors to read MMIO regs.

powerpc/QE: use arch_initcall to probe QUICC Engine GPIOs

2008-06-26T06:49:09+00:00

It was discussed that global arch_initcall() is preferred way to probe
QE GPIOs, so let's use it.

powerpc/QE: qe_reset should be __init

This patch fixes following section mismatch:

powerpc/QE: switch to the cpm_muram implementation

2008-06-10T16:11:21+00:00

This is very trivial patch. We're transitioning to the cpm_muram_*
calls. That's it.

Less trivial changes:
- BD_SC_* defines were defined in the cpm.h and qe.h, so to avoid redefines
  we remove BD_SC from the qe.h and use cpm.h along with cpm_muram_*
  prototypes;
- qe_muram_dump was unused and thus removed;
- added some code to the cpm_common.c to support legacy QE bindings
  (data-only node name).
- For convenience, define qe_* calls to cpm_*. So drivers need not to be
  changed.

powerpc/QE: prepare QE PIO code for GPIO LIB support

2008-06-10T15:39:18+00:00

- split and export __par_io_config_pin() out of par_io_config_pin(), so we
  could use the prefixed version with GPIO LIB API;
- rename struct port_regs to qe_pio_regs, and place it into qe.h;
- rename #define NUM_OF_PINS to QE_PIO_PINS, and place it into qe.h.

powerpc/QE: add support for QE USB clocks routing

2008-06-10T15:39:13+00:00

This patch adds a function to the qe_lib to setup QE USB clocks routing.
To setup clocks safely, cmxgcr register needs locking, so I just reused
ucc_lock since it was used only to protect cmxgcr.

The idea behind placing clocks routing functions into the qe_lib is that
later we'll hopefully switch to the generic Linux Clock API, thus, for
example, FHCI driver may be used for QE and CPM chips without nasty #ifdefs.

This patch also fixes QE_USB_RESTART_TX command definition in the qe.h.
