powerpc/qe&cpm: Implement static inline stubs for non-QE/CPM builds

2009-11-12T03:43:20+00:00

This is needed to avoid ugly #ifdefs in drivers. Also update fsl_qe_udc
driver so that now it doesn't define its own versions that cause build
breakage when the generic stubs are used.

powerpc/qe: QE also shuts down on MPC8568

2009-11-12T03:43:15+00:00

It appears that QE shuts down on all MPC85xx CPUs (i.e. MPC8568 and
MPC8569) and thus needs reset upon resume.

So modify qe_alive_during_sleep() to account that.

powerpc/qe: Make qe_reset() code path safe for repeated invocation

2009-11-12T03:43:13+00:00

For MPC8569 CPUs we'll need to reset QE after each suspend, so make
qe_reset() code path suitable for repeated invocation, that is:

- Don't initialize rheap structures if already initialized;
- Don't allocate muram for SDMA if already allocated, just reinitialize
  registers with previously allocated muram offset;
- Remove __init attributes from qe_reset() and cpm_muram_init();

powerpc/qe: Add qe_upload_firmware() stub for non-QE builds

2009-11-12T03:43:11+00:00

This is needed to avoid #ifdefs in MPC85xx suspend/resume code.

powerpc/qe: Implement qe_alive_during_sleep() helper function

2009-08-31T04:51:33+00:00

In some CPUs (i.e. MPC8569) QE shuts down completely during sleep,
drivers may want to know that to reinitialize registers and buffer
descriptors.

This patch implements qe_alive_during_sleep() helper function, so far
it just checks if MPC8569-compatible power management controller is
present, which is a sign that QE turns off during sleep.

powerpc/qe: update QE Serial Number

2009-05-19T05:50:24+00:00

The latest QE chip may have more Serial Number(SNUM)s of thread to use. We
will get the number of SNUMs from device tree by reading the new property
"fsl,qe-num-snums", and set 28 as the default number of SNUMs so that it is
compatible with the old QE chips' device trees which don't have this new
property. The macro QE_NUM_OF_SNUM is defined as the maximum number in QE
snum table which is 256.

Also we update the snum_init[] array with 18 more new SNUMs which are
confirmed to be useful on new chip.

Change the RISC allocation to macros instead of enum, add function to read

the qe node in dts. Add new property "fsl,qe-num-riscs" description in

powerpc/qe: add Ethernet UPSMR definitions to QE library

2009-01-07T15:18:53+00:00

Add the UCC_GETH_UPSMR_xxx definitions to qe.h.  The ucc_geth driver will
eventually use these instead of the UPSMR_ macros it currently defines.
