[U-Boot] [RESEND PATCH v7 00/10] Add VID support for QDS and RDB platforms

[Rajesh Bhagat]

Adds LTC3882 voltage regulator chip support in common VID driver.
And adds VID support for LS1088A QDS and RDB platforms.

Rajesh Bhagat (10):
  armv8: lsch3: Add serdes and DDR voltage setup
  board: common:vid: Add LS1088A VID Supported voltage values
  board: common: vid: Add board specific vdd adjust API
  board: common: vid: Move IR chip specific code in flag
  Kconfig: Add LTC3882 voltage regulator config
  board: common: vid: Add support for LTC3882 voltage regulator chip
  ddr: fsl: set cdr1 first in case 0.9v VDD is enabled for some SoCs
  ls1088a: ddr: configure DDR for 0.9v for VID support
  common: board_f: vid: Add VID specific API to adjust core voltage
  ls1088a: Add VID support for QDS and RDB platforms

Changes in v7:
  - Used APIs clr/set/clrsetbits_le32() for code clarity
  - Defined CONFIG_VID in SPL scenario too                                       
  - Defined new API init_func_vid for core voltage adjustment for LS1088A

Changes in v6:
  - Corrected indentation/alignment issues at various places
  - Changed NULL ENTRY in srds_prctl_info array to id as zero
  - Corrected the PLL Reset logic, moved code inside for loop
  - Used error code(-EINVAL) in setup_serdes_volt API

Changes in v5:
  - Moved local macros to static functions
  - Used array to handle PRCTL mask and shift operations
  - Tested on LS2080RDB, working fine

Changes in v4:
  - Added local macros instead of magical numbers
  - Created macros to remove duplicate code

Changes in v3:
 Restructured LS1088A VID support to use common VID driver
 Cosmetic review comments fixed
 Added __iomem for accessing registers
 Added the coding for voltage in comments i.e. 1/4096V
 Removed APIs getLSB/MSB and used bit operations. 

Changes in v2:
 Checkpatch errors fixed
