Hi, This is v6 version of the patch series which adds support for MSM8996. Adds HS400 driver support as well. These are tested on internal msm8996 & db410c HW. Changes from v5 -> v6 :- 1. Earlier in v5 series DT node was added to get the clk-rates table needed for sdhci-msm driver. But this is removed in this(v6) patch series and instead the clk changes are done in the clk driver as per Rob H comment. 2. Added clk driver changes(patch 1-3) to provide floor rate values of requested clock for sdhc client. For following boards- apq8084, msm8996, msm8916, msm8974. 3. Other minor patch comments were addressed. Changes from v4 -> v5 :- 1. Added HS400 sdhci-msm controller specific changes:- (Patch 10, 11, 12) 2. Addressed comment from Adrian on Patch 07 @[3]. 3. Addressed comment from Arnd on Patch 03, to directly add clk_table into sdhci_msm_host. [4] 4. Addressed comment from Bjorn to not enforce having clk-rates property in DT for older targets based on discussion at [5] 5. Retained Acks from Adrian on patches (01 & 02 & 06) where there were no changes made while addressing above comments. Older history:- This is v4 version of the patch series. Patches 01, 02, 05 & 06 were Acked-by Adrian. Changes from v3 -> v4 :- 1. Addressed comments from Adrian on Patch 03, 07, 08. 2. Addressed comments from Bjorn on Patch 03. 3. Added clk-rate support for sdhc DT nodes to all MSM platforms. in Pacth 04. 4. Rebased on next branch of Ulf. Changes from v2 -> v3 :- 1. Addded Patch 01 based on Bjorn comment[2] - This fixes/unrolls the poor coding style of read/writes of registers from base sdhci-msm driver. 2. Fixed/unrolled poor style of reads/writes of registers in Patch 02, based on Bjorn comment[2]. Also changed name of flag from use_updated_dll_reset -> use_14lpp_dll_reset. Changes from v1->v2 :- 1. Removed patch 06 & 08 from v1 patch series[1] (which were introducing unnecessary quirks). 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 0001-0003- Adds support in qcom clk driver to return floor value of requested clock rate instead of ceil rate for sdhc clients. Patch 0004- 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 06-08 bring in required change for this to sdhci-msm. MSM controller would require 2x clock rate from source for DDR bus speed modes. Patch 09 adds this support. Patch 0010- adds DDR support in DT for sdhc1 of msm8916. Patches 0011-0014- Adds HS400 support to sdhci-msm.
