powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00+00:00

from include/asm-powerpc.  This is the result of a

mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm

Followed by a few documentation/comment fixups and a couple of places
where  was being used explicitly.  Of the latter only
one was outside the arch code and it is a driver only built for powerpc.

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

2008-06-11T18:46:24+00:00

This patch fixes following section mismatch:

WARNING: arch/powerpc/sysdev/built-in.o(.text+0x11d8): Section mismatch in
reference from the function qe_reset() to the function
.init.text:cpm_muram_init()

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: implement support for the GPIO LIB API

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

This is needed to access QE GPIOs via Linux GPIO API.

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.

[POWERPC] QE: implement qe_muram_offset

2008-04-17T06:01:39+00:00

qe_muram_offset is the reverse of the qe_muram_addr, will be
used for the Freescale QE USB Host Controller driver.

This patch also moves qe_muram_addr into the qe.h header, plus
adds __iomem hints to use with sparse.

[POWERPC] QE: Add ability to upload QE firmware

2008-01-24T01:34:06+00:00

Define the layout of a binary blob that contains a QE firmware and instructions
on how to upload it.  Add function qe_upload_firmware() to parse the blob
and perform the actual upload.  Fully define 'struct rsp' in immap_qe.h to
include the actual RISC Special Registers.  Added description of a new
QE firmware node to booting-without-of.txt.
