MIPS: ath79: Fix the DDR control initialization on ar71xx and ar934x

2015-12-09T19:34:14+00:00

commit 5011a7e808c9fec643d752c5a495a48f27268a48 upstream. The DDR control initialization needs to know the SoC type, however ath79_detect_sys_type() was called after ath79_ddr_ctrl_init(). Reverse the order to fix the DDR control initialization on ar71xx and ar934x.

MIPS: ATH79: Add irq chip ar7240-misc-intc

2015-09-22T17:07:11+00:00

The ar7240 misc irq chip use ack handler instead of ack_mask handler.

MIPS: ATH79: Set missing irq ack handler for ar7100-misc-intc irq chip

2015-09-22T17:05:56+00:00

The irq ack handler was forgotten while introducing OF support. Only ar71xx and ar933x based devices require it.

genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51+00:00

Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help! Signed-off-by: Thomas Gleixner Cc: Julia Lawall Cc: Jiang Liu

MIPS: ath79: Move the GPIO driver to drivers/gpio

MIPS: Ath79: Remove the unused GPIO function API

2015-09-03T10:08:02+00:00

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.

MIPS: ath91: Remove pointless irqdisable/enable

2015-08-26T13:23:31+00:00

The various interrupt flow handlers in ath79 are cascading interrupt handlers. They all have a disable_irq_nosync()/enable_irq() pair around the generic_handle_irq() call. The value of this disable/enable is zero because its a complete noop: disable_irq_nosync() merily increments the disable count without actually masking the interrupt. enable_irq() soleley decrements the disable count without touching the interrupt chip. The interrupt cannot arrive again because the complete call chain runs with interrupts disabled. Remove it.

MIPS: Export get_c0_perfcount_int()

2015-08-03T07:25:18+00:00

get_c0_perfcount_int is tested from oprofile code. If oprofile is compiled as module, get_c0_perfcount_int needs to be exported, otherwise it cannot be resolved.

MIPS: Add basic support for the TL-WR1043ND version 1

2015-06-21T19:54:10+00:00

Add a DTS for TL-WR1043ND version 1 and allow to have it built in the kernel to circumvent the broken u-boot found on these boards. Currently only the UART, LEDs and buttons are supported. Signed-off-by: Alban Bedel Cc: linux-mips@linux-mips.org Signed-off-by: Ralf Baechle
