2012-05-21MIPS: pci: convert lantiq driver to OFJohn Crispin
Implement support for OF inside the lantiq PCI driver. The patch also splits pcibios_plat_dev_init and pcibios_map_irq out into their own file to accomodate coexistance with the upcoming pcie driver.

2012-05-21MIPS: lantiq: implement support for clkdev apiJohn Crispin
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.

2012-05-21MIPS: lantiq: drop ltq_gpio_request() and gpio_to_irq()John Crispin
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.

2012-05-21OF: MIPS: lantiq: implement irq_domain supportJohn Crispin
Add support for irq_domain on lantiq socs. The conversion is straight forward as the ICU found inside the socs allows the usage of irq_domain_add_linear. Harware IRQ 0->7 are the generic MIPS IRQs. 8->199 are the Lantiq IRQ Modules. Our irq_chip callbacks need to substract 8 (MIPS_CPU_IRQ_CASCADE) from d->hwirq to find out the correct offset into the Interrupt Modules register range.

2012-05-16MIPS: Move cache setup to setup_arch().David Daney
commit 97ce2c88f9ad42e3c60a9beb9fca87abf3639faa (jump-label: initialize jump-label subsystem much earlier) breaks MIPS. The jump_label_init() call was moved before trap_init() which is where we initialize flush_icache_range(). In order to be good citizens, we move cache initialization earlier so that we don't jump through a null flush_icache_range function pointer when doing the jump label initialization.
