2015-11-11MIPS: lantiq: Initialize the USB core on bootJohn Crispin
There is a DWC2 USB core in these SoCs. To make USB work we need to first reset and power the state machine. These are SoC specific registers and not part of the actual USB core.

2015-11-11MIPS: Lantiq: Fix check for return value of request_mem_region()Hauke Mehrtens
request_mem_region() returns a pointer and not an integer with an error value. A check for "< 0" on a pointer will cause problems, replace it with not null checks instead. This was found with sparse.

2014-11-24MIPS: lantiq: reboot gphy on restartJohn Crispin
A reboot sometimes lead to a none working phy. An explicit reboot fixes the problem. Signed-off-by: John Crispin <blogic@openwrt.org> Patchwork: http://patchwork.linux-mips.org/patch/8044/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Explicitly enable the clock gate of the internal GPHYs found on xrx200. Signed-off-by: John Crispin <blogic@openwrt.org> Patchwork: http://patchwork.linux-mips.org/patch/4816/
2012-11-11MIPS: lantiq: adds code for booting GPHYJohn Crispin
The XRX200 family of SoCs has embedded gigabit PHYs. This patch adds code to boot them up. Signed-off-by: John Crispin <blogic@openwrt.org> Patchwork: http://patchwork.linux-mips.org/patch/4522

2011-12-07MIPS: Fix up inconsistency in panic() string argument.Ralf Baechle
Panic() invokes printk() to add a \n internally, so panic arguments should not themselves end in \n. Panic invocations in arch/mips and elsewhere are inconsistently sometimes terminating in \n, sometimes not. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2011-11-14MIPS: lantiq: use export.h in favour of module.hJohn Crispin
The code located at arch/mips/lantiq/ included module.h to be able to use the EXPORT_SYMBOL* macros. These can now be directly included using export.h.

2011-05-19MIPS: Lantiq: add SoC specific code for XWAY familyJohn Crispin
Add support for the Lantiq XWAY family of Mips24KEc SoCs. * Danube (PSB50702) * Twinpass (PSB4000) * AR9 (PSB50802) * Amazon SE (PSB5061) The Amazon SE is a lightweight SoC and has no PCI as well as a different clock. We split the code out into seperate files to handle this. The GPIO pins on the SoCs are multi function and there are several bits we can use to configure the pins. To be as compatible as possible to GPIOLIB we add a function int lq_gpio_request(unsigned int pin, unsigned int alt0, unsigned int alt1, unsigned int dir, const char *name); which lets you configure the 2 "alternate function" bits. This way drivers like PCI can make use of GPIOLIB without a cubersome wrapper. The PLL code inside arch/mips/lantiq/xway/clk-xway.c is voodoo to me. It was taken from a 2.4.20 source tree and was never really changed by me since then.
