net: mediatek: Explicitly include pinctrl headers

2018-02-05T17:41:54Z

The Mediatek ethernet driver fails to build after commit 23c35f48f5fb ("pinctrl: remove include file from ") because it relies on the pinctrl/consumer.h and pinctrl/devinfo.h being pulled in by the device.h header implicitly. Include these headers explicitly to avoid the build failure. Cc: Linus Walleij Signed-off-by: Thierry Reding Signed-off-by: Linus Torvalds

net: mediatek: remove superfluous pin setup for MT7622 SoC

2017-12-26T17:05:46Z

Remove superfluous pin setup to get out of accessing invalid I/O pin registers because the way for pin configuring tends to be different from various SoCs and thus it should be better being managed and controlled by the pinctrl driver which MT7622 already can support.

net: mediatek: setup proper state for disabled GMAC on the default

2017-12-19T18:18:31Z

The current solution would setup fixed and force link of 1Gbps to the both GMAC on the default. However, The GMAC should always be put to link down state when the GMAC is disabled on certain target boards. Otherwise, the driver possibly receives unexpected data from the floating hardware connection through the unused GMAC. Although the driver had been added certain protection in RX path to get rid of such kind of unexpected data sent to the upper stack. Signed-off-by: Sean Wang Signed-off-by: David S. Miller

drivers, net, ethernet: convert mtk_eth.dma_refcnt from atomic_t to refcount_t

2017-10-22T01:22:38Z

atomic_t variables are currently used to implement reference counters with the following properties: - counter is initialized to 1 using atomic_set() - a resource is freed upon counter reaching zero - once counter reaches zero, its further increments aren't allowed - counter schema uses basic atomic operations (set, inc, inc_not_zero, dec_and_test, etc.) Such atomic variables should be converted to a newly provided refcount_t type and API that prevents accidental counter overflows and underflows. This is important since overflows and underflows can lead to use-after-free situation and be exploitable. The variable mtk_eth.dma_refcnt is used as pure reference counter. Convert it to refcount_t and fix up the operations. Suggested-by: Kees Cook Reviewed-by: David Windsor Reviewed-by: Hans Liljestrand Signed-off-by: Elena Reshetova Signed-off-by: David S. Miller

net-next: mediatek: bring up QDMA RX ring 0

2017-08-10T05:45:36Z

This patch is in preparation for adding HW flow and QoS offloading. For those features to work, the driver needs to bring up the first QDMA RX ring. This ring is used by the PPE offloading HW. Signed-off-by: John Crisp in Signed-off-by: David S. Miller

net-next: mediatek: fix typos inside the header file

Trivial patch fixing 2 typos. Signed-off-by: John Crispin Signed-off-by: David S. Miller

net-next: mediatek: add support for MediaTek MT7622 SoC

2017-08-01T22:51:48Z

This patch adds the driver for ethernet controller on MT7622 SoC. It has the similar handling logic as the previously MT7623 does, but there are additions against with MT7623 SoC, the shared SGMII given for the dual GMACs and including 5-ports 10/100 embedded switch support (ESW) as the GMAC1 option, thus more clocks consumers for the extra feature are introduced here. So for ease portability and maintenance, those differences all are being kept inside the platform data as other drivers usually do. Currently testing successfully is done with those patches for the conditions such as GMAC2 with IP1001 PHY via RGMII and GMAC1/2 with RTL8211F PHY via SGMII.

net-next: mediatek: add platform data to adapt into various hardware

2017-08-01T22:51:48Z

This patch is the preparation patch in order to adapt into various hardware through adding platform data which holds specific characteristics among MediaTek SoCs and introducing the unified clock handler for those distinct clock requirements depending on different features such as TRGMII and SGMII getting support on the target SoC. And finally, add enhancement with given the generic description for Kconfig and remove the unnecessary machine type dependency in Makefile. Signed-off-by: Sean Wang Signed-off-by: David S. Miller

net: ethernet: mediatek: Explicitly include linux/interrupt.h

2017-07-24T20:45:29Z

The mediatek ethernet driver uses interrupts but does not explicitly include linux/interrupt.h, relying on implicit includes. Fix this so we don't get build breaks as happened for ARM in next-20170720. Signed-off-by: Mark Brown Signed-off-by: David S. Miller
