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://git.infradead.org/users/hesselba/linux-berlin.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
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.

Sebastian Hesselbarth (12):
  mmc: sdhci-pxav2: Drop unused struct sdhci_pxa
  mmc: sdhci-pxav3: Respect MMC_DDR52 timing on uhs signaling
  mmc: sdhci-pxav3: Move private driver data to driver source
  mmc: sdhci-pxav3: Remove unused clk_enable from sdhci_pxa
  mmc: sdhci-pxav3: Remove checks for mandatory host clock
  mmc: sdhci-pxav3: Move I/O clock to private data
  mmc: sdhci-pxav3: Try to get named I/O clock first
  mmc: sdhci-pxav3: Get optional core clock
  mmc: sdhci-pxav3: Document clocks and additional clock-names property
  ARM: dts: berlin: Add SDHCI controller nodes to BG2/BG2CD
  ARM: dts: berlin: Enable WiFi on Google Chromecast
  ARM: dts: berlin: Enable eMMC on Sony NSZ-GS7
