[PATCH v4 0/3] Syscon support for iProc touchscreen driver

[Raveendra Padasalagi]

This patchset is based on v4.5-rc3 tag and its tested on
Broadcom Cygnus SoC.

The patches can be fetched from iproc-tsc-v4 branch of
https://github.com/Broadcom/arm64-linux.git

Changes since v3:
 - Renamed touchscreen node "tsc" to "touchscreen" in dt binding document
 - Added support for syscon only based register access in touch screen
   driver and removed "regs" based register access. Updated dt binding
   document to reflect the changes.
 - Removed "brcm,iproc-touchscreen-syscon" compatible string support in
   dt binding document and touchscreen driver implementation.

Changes since v2:
 - Omitted '0x' in "tsc node" definition in dt documentation file
 - Omitted '0x' in "ts_adc_syscon" definition in dt documentation file
 - Added "brcm,iproc-ts-adc-syscon" compatible string in "ts_adc_syscon"
   node. Updated dt documentation file to reflect this change.

Changes since v1:
 - Enhanced touchscreen driver to handle syscon based register access if
   "brcm,iproc-touchscreen-syscon" compatible string is provided in dt
 - Normal register access is handled through readl and writel API's if
   "brcm,iproc-touchscreen" compatible string is provided.
 - Updated touchscreen dt node document to reflect the new changes.
 - Updated change logs in each patchset to reflect the new changes
