Subject: [PATCH V3 0/2] add Qualcomm QCA7000 ethernet driver
Date: Fri, 26 Sep 2014 22:21:19 +0000 [thread overview]
Message-ID: <1411770081-20995-1-git-send-email-stefan.wahren@i2se.com> (raw)
This patch series adds support for the Qualcomm QCA7000 Homeplug GreenPHY.
The QCA7000 is serial-to-powerline bridge with two interfaces: UART and SPI.
These patches handles only the last one, with an Ethernet over SPI protocol
driver.
This driver based on the Qualcomm code [1], but contains a lot of changes
since last year:
* devicetree support
* DebugFS support
* ethtool support
* better error handling
* performance improvements
* code cleanup
* some bugfixes
The code has been tested only on Freescale i.MX28 boards, but should work
on other platforms.

Changes in V3:
- Use ether_addr_copy instead of memcpy
- Remove qcaspi_set_mac_address
- Improve DT parsing
- replace OF_GPIO dependancy with OF
- fix compile error caused by SET_ETHTOOL_OPS
- fix possible endless loop when spi read fails
- fix DT documentation
- fix coding style
- fix sparse warnings
Changes in V2:
- replace in DT the SPI intr GPIO with pure interrupt
- make legacy mode a boolean DT property and remove it as module parameter
- make burst length a module parameter instead of DT property
- make pluggable a module parameter instead of DT property
- improve DT documentation
- replace debugFS register dump with ethtool function
- replace debugFS stats with ethtool function
- implement function to get ring parameter via ethtool
- implement function to set TX ring count via ethtool
- fix TX ring state in debugFS
- optimize tx ring flush
- add byte limit for TX ring to avoid bufferbloat
- fix TX queue full and write buffer miss counter
- fix SPI clk speed module parameter
- fix possible packet loss
- fix possible race during transmit
