Subject: [PATCH V8 0/5] Add Genesys Logic GL975x support

From: Ben Chuang <ben.chuang@...esyslogic.com.tw>

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

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
