Subject: [PATCH 0/9] Omap mux changes for v2.6.33 merge window, v2
Date: Wed, 02 Dec 2009 16:21:08 -0800	[thread overview]
Message-ID: <20091203001601.2769.20621.stgit@localhost> (raw)

Hi all,

I've updated this series to only map GPIO pins to mux registers
if CONFIG_OMAP_MUX is not set. Those are needed for dynamic muxing
for off-idle.

I've also added omap36xx support, which I have not been able to
test. People with 36xx boards, please give it a try.

Also fixed several checkpatch.pl warnings.

Again big thanks for Benoit Cousson <b-cousson@ti.com> and
Paul Walmsley <paul@pwsan.com> for help in getting the mux
data generated!

Regards,

Tony

Here are some instructions on how to use:

To see what got muxed during init, edit the kernel
CMDLINE to have debug in it:

# dmesg | grep mux
mux: Setting signal i2c2_scl.i2c2_scl 0x0100 -> 0x0100
mux: Setting signal i2c2_sda.i2c2_sda 0x0100 -> 0x0100
mux: Setting signal i2c3_scl.i2c3_scl 0x0100 -> 0x0100
mux: Setting signal i2c3_sda.i2c3_sda 0x0100 -> 0x0100
mux: Setting signal gpmc_ncs3.gpio54 0x410c -> 0x010c
...

Looks like the gpmc_ncs3.gpio54 muxing in the kernel
has a bug where we should have OMAP_WAKEUP_EN set for
board_smc91x_init for board-rx51? :)

To override bootloader mux settings, edit the kernel CMDLINE:

omap_mux=i2c2_scl.i2c2_scl=0x100,i2c2_sda.i2c2_sda=0x100

Note that this only changes the bootloader settings, not
what might be muxed from the board-*.c files.

With CONFIG_DEBUG_FS set:

# mount -t sysfs sys /sys
# mount -t debugfs debug /sys/kernel/debug

# ls /sys/kernel/debug/omap_mux/i2c
i2c2_scl  i2c2_sda  i2c3_scl  i2c3_sda  i2c4_scl  i2c4_sda

# cat /sys/kernel/debug/omap_mux/i2c2_scl
name: i2c2_scl.i2c2_scl (0x480021be/0x18e = 0x0100), b af15, t NA
mode: OMAP_PIN_INPUT | OMAP_MUX_MODE0
signals: i2c2_scl | NA | NA | NA | gpio_168 | NA | NA | safe_mode
