* Revert "ramips: mmc: Sync with staging drivers"John Crispin2018-05-155-2693/+3418

* staging: mt7621-eth: fix return value check in mt7621_gsw_probe()Wei Yongjun2018-05-153-6/+6
| | | | | | | | | | In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Fixes: f079b6406348 ("staging: mt7621-eth: add gigabit switch driver (GSW)") Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| | | | | | | | | | In case of error, the function of_phy_connect() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.

* ramips: mmc: Sync with staging driversRosen Penev2018-05-155-3418/+2693
| | | | | | | | | | | | | Mostly whitespace cleanups. Some unneeded code was removed. MMC init was also moved to the probe function as in 6069bdd0871a20b5adce8d2f677946e05a2da609 The cleanup commits are over 100, making it hard to do them individually. Tested on GnuBee PC1 with an SD card being used as swap. Signed-off-by: Rosen Penev <rosenp@gmail.com>
* ramips: move mtk-mmc init to probe function to avoid breaking NAND flashFelix Fietkau2018-05-081-36/+28
| | | | | | | The driver messes with the pin control settings - MMC and NAND are mutually exclusive Signed-off-by: Felix Fietkau <nbd@nbd.name>
* ramips: fix locking issues in the ethernet driverFelix Fietkau2018-04-171-2/+3
| | | | | | | The stats update needs to protect against being interrupted by a tasklet The u64 stats seqlock needs to be initialized Signed-off-by: Felix Fietkau <nbd@nbd.name>

* ramips: implement hardware NAT offload for MT7621John Crispin2018-04-067-3/+975
| | | | | | | | | | Supports IPv4 flow offloading on MT7621 for Routing, SNAT and DNAT Supported are regular ethernet->ethernet connections, including one 802.1q VLAN and/or PPPoE encapsulation Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
* ramips: mtk-mmc: don't advertise highmem support.NeilBrown2018-04-051-0/+1
| | | | | | | | | | | | | | | | of_dma_configure() sets a default ->dma_mask of DMA_BIT_MASK(32), claiming devices can DMA from the full 32bit address space. The mtk-mmc driver does not support access to highmem pages, so it is really limited to the bottom 512M (actually 448M due to 64M of IO space). Setting ->dma_mask to NULL causes mmc_setup_queue() to fall-back to using BLK_BOUNCE_HIGH to tell the block layer to use a bounce-buffer for any highmem pages requiring IO.

* ramips: fix BUG_ON on mtk-mmc driver probeFelix Fietkau2018-04-051-3/+1
| | | | | | | Our .dts files only have one device defined and this is unlikely to change, so statically initialize host->id to 0. Signed-off-by: Felix Fietkau <nbd@nbd.name>

* ramips: mt7620: power up ephy port 4Pawel Dembicki2018-03-061-0/+1
| | | | | | | | | | | In some boards port 4 of mt7620 switch is powered down in bootloader configuration as lan/wan package leak mitigation. Reset ephy port 4 to default settings to power up the port. Signed-off-by: Pawel Dembicki <paweldembicki@gmail.com> [clarify issue in commit message] Signed-off-by: Mathias Kresin <dev@kresin.me>
* ramips: fix MT7621 switch driver IRQ storm on init with linux 4.14Felix Fietkau2018-02-211-4/+7
| | | | | | | | The hardware emits some interrupts while initializing and handling them can mess up the state or cause infinite loops. Fix this by disabling IRQs during init and re-enabling them afterwards Signed-off-by: Felix Fietkau <nbd@nbd.name>
