Subject: [PATCH v6 0/5] Add SPI Driver to HPE GXP Architecture
Date: Thu, 28 Jul 2022 11:14:54 -0500 [thread overview]
Message-ID: <20220728161459.7738-1-nick.hawkins@hpe.com> (raw)

*Removed unnecessary quotes in hpe,gxp-spifi.yaml
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 unnecessary 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.
