MIPS: Alchemy: remove all CONFIG_SOC_AU1??? defines

2011-10-24T22:34:24Z

Now that no driver any longer depends on the CONFIG_SOC_AU1??? symbols, it's time to get rid of them: Move some of the platform devices to the boards which can use them, Rename a few (unused) constants in the header, Replace them with MIPS_ALCHEMY in the various Kconfig files. Finally delete them altogether from the Alchemy Kconfig file. Signed-off-by: Manuel Lauss To: Linux-MIPS Patchwork: https://patchwork.linux-mips.org/patch/2707/ Signed-off-by: Ralf Baechle

MIPS: Alchemy: remove SOC_AU1X00 in favor of MIPS_ALCHEMY

2010-08-05T12:26:06Z

Remove the CONFIG_SOC_AU1X00 Kconfig symbol since its job can also be done by MACH_ALCHEMY, now renamed to MIPS_ALCHEMY. Signed-off-by: Manuel Lauss To: Linux-MIPS Patchwork: https://patchwork.linux-mips.org/patch/1461/ Signed-off-by: Ralf Baechle

MIPS: Alchemy: prom_putchar is board dependent

2010-02-27T11:52:55Z

This patch replaces the general alchemy prom_putchar() implementation in favor of board-specific versions: The UART where the output of prom_putchar is directed to really depends on the board, the current implementation hardcodes this on a per-SoC basis which is just wrong. So a generic uart tx function is provided in the alchemy headers, and the boards can provide their own prom_putchar with custom destination uart, and all in-kernel alchemy boards support early printk.

MIPS: Alchemy: Rewrite GPIO support.

2009-06-17T10:06:28Z

The current in-kernel Alchemy GPIO support is far too inflexible for all my use cases. To address this, the following changes are made: * create generic functions which deal with manipulating the on-chip GPIO1/2 blocks. Such functions are universally useful. * Macros for GPIO2 shared interrupt management and block control. * support for both built-in CONFIG_GPIOLIB and fast, inlined GPIO macros. If CONFIG_GPIOLIB is not enabled, provide linux gpio framework compatibility by directly inlining the GPIO1/2 functions. GPIO access is limited to on-chip ones and they can be accessed as documented in the datasheets (GPIO0-31 and 200-215). If CONFIG_GPIOLIB is selected, two (2) gpio_chip-s, one for GPIO1 and one for GPIO2, are registered. GPIOs can still be accessed by using the numberspace established in the databooks. However this is not yet flexible enough for my uses: My Alchemy systems have a documented "external" gpio interface (fixed, different numberspace) and can support a variety of baseboards, some of which are equipped with I2C gpio expanders. I want to be able to provide the default 16 GPIOs of the CPU board numbered as 0..15 and also support gpio expanders, if present, starting as gpio16. To achieve this, a new Kconfig symbol for Alchemy is introduced, CONFIG_ALCHEMY_GPIO_INDIRECT, which boards can enable to signal that they don't want the Alchemy numberspace exposed to the outside world, but instead want to provide their own. Boards are now respon- sible for providing the linux gpio interface glue code (either in a custom gpio.h header (in board include directory) or with gpio_chips). To make the board-specific inlined gpio functions work, the MIPS Makefile must be changed so that the mach-au1x00/gpio.h header is included _after_ the board headers, by moving the inclusion of the mach-au1x00/ to the end of the header list. See arch/mips/include/asm/mach-au1x00/gpio.h for more info. Signed-off-by: Manuel Lauss Acked-by: Florian Fainelli Signed-off-by: Ralf Baechle

MIPS: Alchemy: RTC counter clocksource / clockevent support.

2009-01-11T09:57:27Z

Add support for the 32 kHz counter1 (RTC) as clocksource / clockevent device. As a nice side effect, this also enables use of the 'wait' instruction for runtime idle power savings. If the counters aren't enabled/working properly, fall back on the cp0 counter clock code. Signed-off-by: Manuel Lauss Signed-off-by: Ralf Baechle

MIPS: Alchemy: update core interrupt code.

2009-01-11T09:57:26Z

This patch attempts to modernize core Alchemy interrupt handling code. - add irq_chips for irq controllers instead of irq type, - add a set_type() hook to change irq trigger type during runtime, - add a set_wake() hook to control GPIO0..7 based wakeup, - use linux' IRQF_TRIGGER_ constants instead of homebrew ones, - enable GENERIC_HARDIRQS_NO__DO_IRQ. - simplify plat_irq_dispatch - merge au1xxx_irqmap into irq.c file, the only place where its contents are referenced. - board_init_irq() is now mandatory for every board; use it to register the remaining (gpio-based) interrupt sources; update all boards accordingly. Run-tested on Db1200 and other Au1200 based platforms. Signed-off-by: Manuel Lauss Signed-off-by: Ralf Baechle delete mode 100644 arch/mips/alchemy/common/au1xxx_irqmap.c
