MIPS: ath79: fix register address in ath79_ddr_wb_flush()

2018-07-28T05:45:02+00:00

commit bc88ad2efd11f29e00a4fd60fcd1887abfe76833 upstream.

ath79_ddr_wb_flush_base has the type void __iomem *, so register offsets
need to be a multiple of 4 in order to access the intended register.

MIPS: ath79: fix regression in PCI window initialization

MIPS: ath79: make bootconsole wait for both THRE and TEMT

2016-06-08T01:14:31+00:00

commit f5b556c94c8490d42fea79d7b4ae0ecbc291e69d upstream.

This makes the ath79 bootconsole behave the same way as the generic 8250
bootconsole.

Also waiting for TEMT (transmit buffer is empty) instead of just THRE
(transmit buffer is not full) ensures that all characters have been
transmitted before the real serial driver starts reconfiguring the serial
controller (which would sometimes result in garbage being transmitted.)
This change does not cause a visible performance loss.

In addition, this seems to fix a hang observed in certain configurations on
many AR7xxx/AR9xxx SoCs during autoconfig of the real serial driver.

A more complete follow-up patch will disable 8250 autoconfig for ath79
altogether (the serial controller is detected as a 16550A, which is not
fully compatible with the ath79 serial, and the autoconfig may lead to
undefined behavior on ath79.)

MIPS: ath79: Add a machine entry for booting OF machines

2015-11-20T14:44:57+00:00

As I'm using a board with a broken old bootloader I hardcoded the
mips_machtype and did't notice that the machine entry was still
missing.

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

2015-11-20T11:10:09+00:00

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: 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!
