From: Ben Chuang <ben.chuang@xxxxxxxxxxxxxxxxxxx>

The patches modify internal clock setup to match SD Host Controller
Simplified Specifications 4.20 and support Genesys Logic GL9750/GL9755
chipsets.

v9:
- refine gli_set_9750_rx_inv()
- modify comments in sdhci_gli_voltage_switch()

v8:
refine codes in sdhci-gli-pci.c
- remove duplicate assignment
- remove redundant delay
- use '!!'(not not) logical operator to refine the true/false condition
- check end condition after outter loop
- add comments for delay 5ms in sdhci_gli_voltage_switch()
- merge two logical conditions to one line

v7:
- remove condition define CONFIG_MMC_SDHCI_IO_ACCESSORS from sdhci-pci-gli.c
- making the accessors(MMC_SDHCI_IO_ACCESSORS) always available when selecting
MMC_SDHCI_PCI in Kconfig

V6:
- export sdhci_abot_tuning() function symbol
- use C-style comments
- use BIT, FIELD_{GET,PREP} and GENMASK to define bit fields of register
- use host->ops->platform_execute_tuning instead of mmc->ops->execute_tuning
- call sdhci_reset() instead of duplicating the code in sdhci_gl9750_reset
- remove .hw_reset
- use condition define CONFIG_MMC_SDHCI_IO_ACCESSORS for read_l

V5:
- add "change timeout of loop .." to a patch
- fix typo "verndor" to "vendor"

V4:
- change name from sdhci_gli_reset to sdhci_gl9750_reset
- fix sdhci_reset to sdhci_gl9750_reset in sdhci_gl9750_ops
- fix sdhci_gli_reset to sdhci_reset in sdhci_gl9755_ops

V3:
- change usleep_range to udelay
- add Genesys Logic PCI Vendor ID to a patch
- separate the Genesys Logic specific part to a patch

V2:
- change udelay to usleep_range

Ben Chuang (5):
mmc: sdhci: Change timeout of loop for checking internal clock stable
mmc: sdhci: Add PLL Enable support to internal clock setup
PCI: Add Genesys Logic, Inc. Vendor ID
mmc: sdhci: Export sdhci_abort_tuning function symbol
mmc: host: sdhci-pci: Add Genesys Logic GL975x support
