* GPIO: MIPS: lantiq: move gpio-stp and gpio-ebu to the subsystem folderJohn Crispin2012-05-213-279/+1
| | | | | | | | | | | | | | Move the 2 drivers from arch/mips/lantiq/xway/ to the subsystem and make them buildable. The following 2 patches will convert the drivers to OF.

* MIPS: lantiq: implement support for clkdev apiJohn Crispin2012-05-217-392/+519
| | | | | | | | | | | | | | This patch unifies all clock generation and gating code into one file. All drivers will now be able to request their clocks via their device. This patch also adds support for the clockout feature, which allows clock generation on external pins. Support for COMMON_CLK will be provided in the next series.

* MIPS: lantiq: drop ltq_gpio_request() and gpio_to_irq()John Crispin2012-05-212-17/+0
| | | | | | | | | | | | | | As part of the conversion to OF we also implement pinctrl drivers. Previously we used ltq_gpio_request() to set pinmuxing. This is now obselete and we can hence drop the function. Additionally we remove gpio_to_irq() from the gpio driver and move it to a header file.

* MIPS: lantiq: drop mips_machine supportJohn Crispin2012-05-218-338/+3
| | | | | | | | | | Before we are able to add OF support, we really want to drop all the bloat needed to register all the platform devices.

* MIPS: Fix up inconsistency in panic() string argument.Ralf Baechle2011-12-074-13/+13
| | | | | | | | 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>

* MIPS: Lantiq: Add ethernet driverJohn Crispin2011-05-192-0/+24
| | | | | | | | | | | | | | | This patch adds the driver for the ETOP Packet Processing Engine (PPE32) found inside the XWAY family of Lantiq MIPS SoCs. This driver makes 100MBit ethernet work. Support for all 8 dma channels, gbit and the embedded switch found on the ar9/vr9 still needs to be implemented.

* MIPS: Lantiq: add SoC specific code for XWAY familyJohn Crispin2011-05-199-0/+777
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.
