* ath79: restore pin state on probe for ar934x-spiChuanhong Guo2020-02-101-5/+11
| | | | | | | | | | | | If bootloader doesn't terminate its last spi operation properly before starting kernel, our first transfer in kernel becomes a continuous transfer to that request instead of a new one. Fix this flaw by restoring IOC register, which restored all pin state to default.

* ath79: add support for Atheros AR934x HS UARTDaniel Golle2020-02-071-0/+52
| | | | | | | | | AR934x chips also got the 'old' qca,ar9330-uart in addition to the 'new' ns16550a compatible one. Add support for UART1 clock selector as well as device-tree bindings in ar934x.dtsi to make use of that uart.

* ath79: ar933x_uart: set UART_CS_{RX,TX}_READY_ORIDEDaniel Golle2020-02-071-0/+64
| | | | | | | | | | | | | | | | On AR934x this UART is usually not initialized by the bootloader as it is only used as a secondary serial port while the primary UART is a newly introduced NS16550-compatible. In order to make use of the ar933x-uart on AR934x without RTS/CTS hardware flow control, one needs to set the UART_CS_{RX,TX}_READY_ORIDE bits as other than on AR933x where this UART is used as primary/console, the bootloader on AR934x typically doesn't set those bits. Setting them explicitely on AR933x does not do any harm, so just set them unconditionally. Tested-by: Chuanhong Guo <gch981213@gmail.com Signed-off-by: Daniel Golle <daniel@makrotopia.org>
* ath79: add new ar934x spi driverChuanhong Guo2020-02-062-0/+338
| | | | | | | | | | | A new shift mode was introduced since ar934x which has a way better performance than current bitbang driver and can handle higher spi clock properly. This commit adds a new driver to make use of this new feature. This new driver has chipselect properly configured and we don't need cs-gpios hack in dts anymore. Remove them.

* ath79: allow to override AR8033 SGMII aneg statusDavid Bauer2020-01-231-0/+16
| | | | | | | | | | | | | In order to make the QCA955x SGMII workaround work, the unsuccessful SGMII autonegotiation on the AR8033 should not block the PHY state-machine. Otherwise, the ag71xx driver never becomes aware of the copper-side link-establishment and the workaround is never executed.

* ath79: add QCA955x SGMII link loss workaroundDavid Bauer2020-01-231-0/+91
| | | | | | | | | | | | | | | | This commit adds a workaround for the loss of the SGMII link observed on the QCA955x generation of SoCs. The workaround originates part from the U-Boot source code, part from the implementation from AVM found in the GPL tarball for the AVM FRITZ!WLAN Repeater 450E. The bug results in a stuck SGMII link between the PHY device and the SoC side. This has only been observed with the Atheros AR8033 PHY and most likely all devices using such combination are affected. It is worked around by reading a hidden SGMII status register and issuing a SGMII PHY reset until the link becomes useable again. Signed-off-by: David Bauer <mail@david-bauer.net>

| | | | | | | | | | | | | Currently the patch only changes break to use goto statement instead. But not necessary acutually since the ret value checked after the for loop. So it is okay for the break case before changed by the patch also. This patch only reverts the following commit partially. https://github.com/openwrt/openwrt/commit/ddc11c3932c7b7b7df7d5fbd48f207e7 Note: The changes are mainly applied into the linux kernel upstream.

* ath79: disable delays on AT803X config initDavid Bauer2019-10-271-0/+27
| | | | | | | | | | | | | | Until upstream commit 6d4cd041f0af("net: phy: at803x: disable delay only for RGMII mode"), delays were not disabled on driver probe for the Atheros AR803x PHYs, although the RX delay is enabled on soft and hard reset. In addition, the TX delay setting is retained on soft-reset. This patch disables both delays on config init to align the behavior with kernel 5.1 and higher. It can be safely dropped with kernel 5.1.

* ath79: add AR934x NAND Flash Controller driverMichal Cieslakiewicz2019-10-201-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch contains updated driver for Atheros NAND Flash Controller written originally by Gabor Juhos for ar71xx (aka 'ar934x-nfc'). ath79 version has adapted to work with kernel 4.19 and Device Tree. It has also been renamed to 'ar934x-nand' to avoid confusion with Near-Field Communication technology. Controller is present on Atheros AR934x SoCs and required for accessing internal flash storage on routers like Netgear WNDR4300. This port preserves all NAND programming code while moving platform configuration to Device Tree and replacing some kernel functions marked for retirement by 4.19. Suitable definition is included in 'ar934x.dtsi' ('nand@1b000200' section). Most important changes to ar71xx version are: * old kernel sections of code removed * 'bool swap_dma' provided by platform data is now set by boolean DT property 'qca,nand-swap-dma' * board-supplied (mach-*.c code) platform data removed - its elements become either unused, redundant or replaced by DT methods (like reset) * IRQ is reserved by devm_request_irq() so free_irq() is not needed anymore * calls to deprecated nand_scan_ident() + nand_scan_tail() function pair replaced by using recommended nand_scan() with attach_chip() callback * ECC is set to hardware by default, can be overriden by standard DT 'nand-ecc-*' properties (software Hamming or BCH are other options) This driver has been successfully tested on Netgear WNDR4300 running experimental ath79 OpenWrt master branch.
