[PATCH v2 0/8] Add clk-rates and DDR support to sdhci-msm

[Ritesh Harjani <riteshh@codeaurora.org>]

Hi All, 

This is v2 version of the patch series. Have addressed
few comments from Jaehoon & Shawn. These were mainly
related to not use any extra quirks or not to add any
unnecessary callback into sdhci.

Changes from v1->v2 :-
1. Removed patch 06 & 08 from v1 patch series[1].
   Instead have implemented __sdhci_msm_set_clock version of
   sdhci_set_clock in sdhci_msm driver itself in patch 07 of
   this patch series.
2. Enabled extra quirk (SDHCI_QUIRK2_PRESET_VALUE_BROKEN) in
   patch 05 of this patch series. 

Description of patches :-
This patchset adds clk-rates & other required changes to
upstream sdhci-msm driver from codeaurora tree.
It has been tested on a db410c Dragonboard and msm8996 based
platform.

Patch 0001 - Adds updated dll sequence for newer controllers
which has minor_version >= 0x42. This is required for msm8996.

MSM controller HW recommendation is to use the base MCI clock
and directly control this MCI clock at GCC in order to
change the clk-rate. 
Patches 02-06 bring in required change for this to
sdhci-msm and DT of db410c.

MSM controller would require 2x clock rate from source
for DDR bus speed modes. Patch 07 adds this support.

Patch 08 - adds DDR support in DT for sdhc1 of msm8916.
