ARM: dts: Fix WLAN regression on omap5-uevm

2015-12-09T19:34:13+00:00

commit 0efc898a9bea7a2e8e583c6efab0e19dc7093078 upstream.

Commit 99f84cae43df ("ARM: dts: add wl12xx/wl18xx bindings") added
device tree bindings for the TI WLAN SDIO on many omap variants.

I recall wondering how come omap5-uevm did not have the WLAN
added and this issue has been bugging me for a while now, and
I finally tracked it down to a bad pinmux regression, and a missing
deferred probe handling for the 32k clock from palmas that's
requested by twl6040.

Basically 392adaf796b9 ("ARM: dts: omap5-evm: Add mcspi data")
added pin muxing for mcspi4 that conflicts with the onboard
WLAN. While some omap5-uevm don't have WLAN populated, the
pins are not reused for other devices. And as the SDIO bus
should be probed, let's try to enable WLAN by default.

Let's fix the regression and add the WLAN configuration as
done for the other boards in 99f84cae43df ("ARM: dts: add
wl12xx/wl18xx bindings"). And let's use the new MMC pwrseq for
the 32k clock as suggested by Javier Martinez Canillas
.

Note that without a related deferred probe fix for twl6040,
the 32k clock is not initialized if palmas-clk is a module
and twl6040 is built-in.

Let's also use the generic "non-removable" instead of the
legacy "ti,non-removable" property while at it.

And finally, note that omap5 seems to require WAKEUP_EN for
the WLAN GPIO interrupt.

ARM: dts: Add vbus regulator to USB2 phy nodes on exynos3250, exynos4210 and exynos4412 boards

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

commit 4ae9a4c66cdcb8b5d4e4d904846f1b450dbcabb4 upstream.

Exynos USB2 PHY driver now supports VBUS regulator, so add it to all
boards which have it available. This also fixes commit
7eec1266751b ("ARM: dts: Add Maxim 77693 PMIC to exynos4412-trats2"),
which added new regulators to Trats2 board, but without linking them to
the consumers.

ARM: dts: imx27.dtsi: change the clock information for usb

2015-12-09T19:34:11+00:00

commit facf47ee6b4d07d43c3bfd6f0762f1b28f64703a upstream.

For imx27, it needs three clocks to let the controller work,
the old code is wrong, and usbmisc has not included clock handling
code any more. Without this patch, it will cause below data
abort when accessing usbmisc registers.

ARM: dts: fix gpio-keys wakeup-source property

2015-10-22T16:53:57+00:00

The keyboard driver for GPIO buttons(gpio-keys) checks for one of the
two boolean properties to enable gpio buttons as wakeup source:
1. "wakeup-source" or
2. the legacy "gpio-key,wakeup"

However juno, ste-snowball and emev2-kzm9d dts file have a undetected
"wakeup" property to indictate the wakeup source.

This patch fixes it by making use of "wakeup-source" property.

Some omaps are producing imprecise external aborts because we are
wrongly trying to init SRAM for device tree based booting. Only
omap3 is still using the legacy SRAM code, so we need to make it
omap3 specific. Otherwise we can get errors like this on at least
dm814x:

Unhandled fault: imprecise external abort (0xc06) at 0xc08b156c
...
(omap_rev) from [] (omap_sram_init+0xf8/0x3e0)

(kernel_init) from [] (ret_from_fork+0x14/0x24)

Let's fix the issue by making sure omap_sdrc_init only gets called for
omap3. To do that, we need to have compatible "ti,omap3" in the dts
files. And let's also use "ti,omap3630" instead of "ti,omap36xx" like
we're supposed to.
