Subject: [PATCH v2 00/13] Support Pensando Elba SoC

This series enables support for Pensando Elba SoC based platforms.
The Elba SoC has the following features:

- Sixteen ARM64 A72 cores
- Dual DDR 4/5 memory controllers
- 32 lanes of PCIe Gen3/4 to the Host
- Network interfaces: Dual 200GE, Quad 100GE, 50GE, 25GE, 10GE and
  also a single 1GE management port.
- Storage/crypto offloads and 144 programmable P4 cores.
- QSPI and EMMC for SoC storage
- Two SPI interfaces for peripheral management
- I2C bus for platform management

See below for an overview of changes since v1.

== Patch overview ==

- 01    Fix typo, return code value and log message.
- 03    Remove else clause, intrinsic DW chip-select is never used.
- 08-11 Split out dts and bindings to sub-patches
- 10    Converted existing cadence-quadspi.txt to YAML schema
- 13    New driver should use <linux/gpio/driver.h>
