ARM: dts: Fix vcsi regulator to be always-on for droid4 to prevent hangs

2019-12-31T15:46:03+00:00

[ Upstream commit ddb52945999dcf35787bf221b62108806182578d ]

In addition to using vcsi regulator for the display, looks like droid4 is
using vcsi regulator to trigger off mode internally with the PMIC firmware
when the SoC enters deeper idle states. This is configured in the Motorola
Mapphone Linux kernel sources as "zerov_regulator".

As we currently don't support off mode during idle for omap4, we must
prevent vcsi from being disabled when the display is blanked to prevent
the PMIC change to off mode. Otherwise the device will hang on entering
idle when the display is blanked.

Before commit 089b3f61ecfc ("regulator: core: Let boot-on regulators be
powered off"), the boot-on regulators never got disabled like they should
and vcsi did not get turned off on idle.

Let's fix the issue by setting vcsi to always-on for now. Later on we may
want to claim the vcsi regulator also in the PM code if needed.

ARM: tegra: Fix FLOW_CTLR_HALT register clobbering by tegra_resume()

2019-12-21T10:04:48+00:00

commit d70f7d31a9e2088e8a507194354d41ea10062994 upstream.

There is an unfortunate typo in the code that results in writing to
FLOW_CTLR_HALT instead of FLOW_CTLR_CSR.

ARM: dts: s3c64xx: Fix init order of clock providers

2019-12-21T10:04:47+00:00

commit d60d0cff4ab01255b25375425745c3cff69558ad upstream.

fin_pll is the parent of clock-controller@7e00f000, specify
the dependency to ensure proper initialization order of clock
providers.

without this patch:
[    0.000000] S3C6410 clocks: apll = 0, mpll = 0
[    0.000000]  epll = 0, arm_clk = 0

with this patch:

omap: pdata-quirks: remove openpandora quirks for mmc3 and wl1251

2019-12-17T18:56:46+00:00

[ Upstream commit 2398c41d64321e62af54424fd399964f3d48cdc2 ]

With a wl1251 child node of mmc3 in the device tree decoded
in omap_hsmmc.c to handle special wl1251 initialization, we do
no longer need to instantiate the mmc3 through pdata quirks.

We also can remove the wlan regulator and reset/interrupt definitions
and do them through device tree.

omap: pdata-quirks: revert pandora specific gpiod additions

2019-12-17T18:56:46+00:00

[ Upstream commit 4e8fad98171babe019db51c15055ec74697e9525 ]

This partly reverts the commit efdfeb079cc3 ("regulator: fixed: Convert to
use GPIO descriptor only").

We must remove this from mainline first, so that the following patch
to remove the openpandora quirks for mmc3 and wl1251 cleanly applies
to stable v4.9, v4.14, v4.19 where the above mentioned patch is not yet
present.

Since the code affected is removed (no pandora gpios in pdata-quirks
and more), there will be no matching revert-of-the-revert.

ARM: dts: omap3-tao3530: Fix incorrect MMC card detection GPIO polarity

2019-12-17T18:56:40+00:00

commit 287897f9aaa2ad1c923d9875914f57c4dc9159c8 upstream.

The MMC card detection GPIO polarity is active low on TAO3530, like in many
other similar boards. Now the card is not detected and it is unable to
mount rootfs from an SD card.

Fix this by using the correct polarity.

This incorrect polarity was defined already in the commit 30d95c6d7092
("ARM: dts: omap3: Add Technexion TAO3530 SOM omap3-tao3530.dtsi") in v3.18
kernel and later changed to use defined GPIO constants in v4.4 kernel by
the commit 3a637e008e54 ("ARM: dts: Use defined GPIO constants in flags
cell for OMAP2+ boards").

While the latter commit did not introduce the issue I'm marking it with
Fixes tag due the v4.4 kernels still being maintained.

ARM: dts: pandora-common: define wl1251 as child node of mmc3

commit 4f9007d692017cef38baf2a9b82b7879d5b2407b upstream.

Since v4.7 the dma initialization requires that there is a
device tree property for "rx" and "tx" channels which is
not provided by the pdata-quirks initialization.

By conversion of the mmc3 setup to device tree this will
finally allows to remove the OpenPandora wlan specific omap3
data-quirks.
