Subject: [PATCH v3 0/5] Add SPI Driver to HPE GXP Architecture
Date:   Fri, 22 Jul 2022 16:49:15 -0500
Message-Id: <20220722214920.40485-1-nick.hawkins@hpe.com>
Precedence: bulk

From: Nick Hawkins <nick.hawkins@hpe.com>

Changes since v3:
 *Fixed indentations in hpe,gxp-spifi.yaml

Changes since v2:
 *Changed the CONFIG_SPI_GXP from y to m in defconfig
 *Removed extra space around < > for reg in hpe,gxp-spifi.yaml
 *Changed interrupt-parrent to interrupt-parent in hpe,gxp-spifi.yaml
 *Removed repeated include file in spi-gxp.c
 *Removed unnecessary initialization of ret variable in spi-gxp.c
 *Removed conditional variable checks where failure is not possible in
  spi-gxp.c
 *Removed unecessary variable cs in spi-gxp.c
 *Removed blank gxp-spifi-remove function in spi-gxp.c
 *Fixed error messages so they are not repetitive

The GXP supports 3 separate SPI interfaces to accommodate the system
flash, core flash, and other functions. The SPI engine supports variable
clock frequency, selectable 3-byte or 4-byte addressing and a
configurable x1, x2, and x4 command/address/data modes. The memory
buffer for reading and writing ranges between 256 bytes and 8KB. This
driver supports access to the core flash and bios part.

Nick Hawkins (5):
  spi: spi-gxp: Add support for HPE GXP SoCs
  spi: dt-bindings: add documentation for hpe,gxp-spifi
  ARM: dts: hpe: Add spi driver node
  ARM: configs: multi_v7_defconfig: Enable HPE GXP SPI driver
  MAINTAINERS: add spi support to GXP
