Timur Tabi f46dad270b powerpc/86xx: don't pretend that we support 8-bit pixels on the MPC8610 HPCD
If the video mode is set to 16-, 24-, or 32-bit pixels, then the pixel data
contains actual levels of red, blue, and green.  However, if the video mode
is set to 8-bit pixels, then the 8-bit value represents an index into color
table.  This is called "palette mode" on the Freescale DIU video controller.

The DIU driver does not currently support palette mode, but the MPC8610 HPCD
board file returned a non-zero (although incorrect) pixel format value for
8-bit mode.

Timur Tabi 4c5ddd5269 powerpc/8610: add probing for individual DMA channels, not just DMA controllers
A future version of the MPC8610 HPCD's ASoC DMA driver will probe on individual
DMA channel nodes, so the DMA controller nodes' compatible string must be listed
in mpc8610_ids[] for the probe to work.

Also remove the "gianfar" compatible from mpc8610_ids[], since there is no
gianfar (or any other networking device) on the 8610.

Anton Vorontsov 8c68e2f788 powerpc/86xx: Add power management support for MPC8610HPCD boards
This patch adds needed nodes and properties to support suspend/resume
on the MPC8610HPCD boards.

There is a dedicated switch (SW9) that is used to wake up the boards.
By default the SW9 button is routed to IRQ8, but could be re-routed
(via PIXIS) to sreset.

With 'no_console_suspend' kernel command line argument specified, the
board is also able to wakeup upon serial port input.

Anton Vorontsov d2998c2c36 powerpc/86xx: add MMC SPI support for MPC8610HPCD boards
This patch adds spi and mmc-spi-slot nodes, plus a gpio-controller for
PIXIS' sdcsr bank that is used for managing SPI chip-select and for
reading card's states.

Kumar Gala 1e76dff22c powerpc/86xx: clean up smp init code
Removed the need for asm/mpc86xx.h as it was only used in mpc86xx_smp.c
and just moved the defines it cared about into there.  Also fixed up
the ioremap to only map the one 4k page we need access to and to iounmap
when we are done.

Anton Vorontsov d8bc55fb33 powerpc/86xx: Move gianfar mdio nodes under the ethernet nodes
Currently it doesn't matter where the mdio nodes are placed, but with
power management support (i.e. when sleep = <> properties will take
effect), mdio nodes placement will become important: mdio controller
is a part of the ethernet block, so the mdio nodes should be placed
correctly. Otherwise we may wrongly assume that MDIO controllers are
available during sleep.

Timur Tabi 43c9f43492 powerpc: remove support for bootmem-allocated memory for the DIU driver
Early versions of the Freescale DIU framebuffer driver depended on a bootmem
allocation of memory for the video buffer.  The need for this feature was
removed in commit 6b51d51a, so now we can remove the platform-specific code
that allocated that memory.

Anton Vorontsov 52ddd1cdc9 powerpc/85xx/86xx: some refactoring for fsl_uli1575 code
- Get rid of uses_fsl_uli_m1575, it does not scale for all cases.
  Instead, let's explicitly use machine_is() for each fixup.
- Factor out MPC8610HPCD quirks to fsl_uli1575, and protect them with
  machine_is(). One step closer to multiplatform kernels.
- Actually use fsl_uli1575 on MPC8610HPCD, so RTC quirk will be applied.
- RTC quirk applies to all boards though, so no machine_is() checks.

it should set and clear its own bits only, otherwise it will break
