Subject[PATCH RESEND 00/12] SDHCI PXA cleanup and clocks
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.

This is a resend of the patches are rebased on v3.18-rc1. As usual
a branch with the patches applied on top of v3.18-rc1 can be found at

git:// devel/bg2-bg2cd-sdhci-v1

Patches 1-9 should go through Chris' mmc tree, I'll pick up the DT
patches 10-12.

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

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.

Sebastian Hesselbarth (12):
