[PATCH 00/12] SDHCI PXA cleanup and clocks

[Sebastian Hesselbarth]

This patch set does a little cleanup on PXA v2/v3 drivers and
adds an additional, optional core clock to v3 driver that is
required on Marvell Berlin BG2 and BG2CD SoCs.

Patch 1 removes the unused private driver data from pxav2 driver.

Patch 2 is a fix for pxav3 driver to honor MMC_DDR52 timing on
uhs signaling. AFAICS, up to now there was no user affected by it
but Sony NSZ-GS7 will be.

Patch 3 moves struct sdhci_pxa from global include to the only
driver using it now. Patch 4 removes the unused clk_enable from
it.

Patch 5 removes some wrong and unnecessary checks on struct clk
from v3 driver. Patch 6 moves the struct clk for I/O clock to
the private driver data, while Patch 7 prepares the driver for
named clocks.

Patch 8 adds support for an additional, optional core clock that
is now also documented in the binding with Patch 9.

Patches 10-12 finally add corresponding sdhci nodes to berlin2
and berlin2cd, Chromecast and NSZ-GS7 DT files.

The patches are currently based on next-20141003 and are intended
for v3.19, i.e. I'll resend the series as soon as v3.18-rc1 drops.

A branch with the patches applied on top of next-201410-03 can be
found on
