2016-01-04MIPS: ath79: Allow using ath79_ddr_wb_flush() from driversAlban Bedel1-1/+0
Move the declaration of ath79_ddr_wb_flush() to asm/mach-ath79/ath79.h to allow using it from drivers. This is needed to move the CPU IRQ driver to drivers/irqchip.

2015-09-03MIPS: Ath79: Remove the unused GPIO function APIAlban Bedel1-3/+0
To prepare moving the GPIO driver to drivers/gpio remove the platform specific pinmux API. As it is not used by any board, and such functionality should better be implemented using the pinmux subsystem just removing it seems to be the best option.

2015-06-21MIPS: ath79: Improve the DDR controller interfaceAlban Bedel1-0/+1
The DDR controller need to be used by the IRQ controller to flush the write buffer of some devices before running the IRQ handler. It is also used by the PCI controller to setup the PCI memory windows. The current interface used to access the DDR controller doesn't provides any useful abstraction and simply rely on a shared global pointer. Replace this by a simple API to setup the PCI memory windows and use the write buffer flush independently of the SoC type. That remove the need for the shared global pointer, simplify the IRQ handler code.

2014-01-25mips: delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2013-09-04MIPS: ath79: Use a helper function to get system clock ratesGabor Juhos1-0/+2
The ath79 platform uses similar code to get the rate of various clocks during init. Separate the similar code into a new helper function and use that to avoid code duplication.

2011-01-18MIPS: ath79: add GPIOLIB supportGabor Juhos1-0/+5

2011-01-18MIPS: Add initial support for the Atheros AR71XX/AR724X/AR931X SoCsGabor Juhos1-0/+26
This patch adds initial support for various Atheros SoCs based on the MIPS 24Kc core. The following models are supported at the moment: - AR7130 - AR7141 - AR7161 - AR9130 - AR9132 - AR7240 - AR7241 - AR7242 The current patch contains minimal support only, but the resulting kernel can boot into user-space with using of an initramfs image on various boards which are using these SoCs. Support for more built-in devices and individual boards will be implemented in further patches.
