Subject: [PATCH v4 0/2] NXP SPIFI driver for LPC18xx/43xx familiy
Date: Thu, 9 Jul 2015 22:19:05 +0200 [thread overview]
Message-ID: <1436473147-31063-1-git-send-email-manabian@gmail.com> (raw)
This patch set adds a SPI-NOR driver for the NXP SPI Flash (SPIFI)
controller that can be found on newer NXP MCUs. For example on the
LPC18xx and LPC43xx familiy.
NXP SPIFI is a specialized SPI interface for serial Flash devices.
It supports one Flash device with 1-, 2- and 4-bits width in SPI
mode 0 or 3. The controller operates in either command or memory
mode. In memory mode the Flash is made accessible for the CPU as
normal memory.
This version fix a bug in the write function discovered during
testing with JFFS2.
Changes since v3:
- fix bug in write function
- rebase on 4.2-rc1
Changes since v2:
- default to auto detection unless chip is specified
- update doc with reference to jedec,spi-nor.txt
Changes since v1:
- use readb_poll_timeout instead of open coding
- cache current mode (memory/command)
- depend on HAS_IOMEM
- removed stray white space
- removed leftover debug print
