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

2019-12-17T18:55:39+00:00

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.

Pull ARM SoC fixes from Olof Johansson:
 "A set of fixes that have trickled in over the last couple of weeks:

   - MAINTAINER update for Cavium/Marvell ThunderX2

   - stm32 tweaks to pinmux for Joystick/Camera, and RAM allocation for
     CAN interfaces

   - i.MX fixes for voltage regulator GPIO mappings, fixes voltage

STM32 DT fixes for v5.4, round 2

Highlights:
-----------

Fixes for STM32MP157:
 -Fix CAN RAM mapping
 -Change stmfx pinctrl definition for joystick and camera. Due to
 stmfx pinctrl fix done in v5.4-rc cycle, camera and joystick were no
 longer functional.

"push-pull" configuration is now fully handled by the gpiolib and the
STMFX pinctrl driver. There is no longer need to declare a pinctrl group
to only configure "push-pull" setting for the line. It is done directly by
the gpiolib.

Split the 10Kbytes CAN message RAM to be able to use simultaneously
FDCAN1 and FDCAN2 instances.
First 5Kbytes are allocated to FDCAN1 and last 5Kbytes are used for
FDCAN2. To do so, set the offset to 0x1400 in mram-cfg for FDCAN2.
