2022-04-29Revert "arm: dts: at91: Fix boolean properties with values"Arnd Bergmann
This reverts commit 0dc23d1a8e17, which caused another regression as the pinctrl code actually expects an integer value of 0 or 1 rather than a simple boolean property. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2022-04-21memory: renesas-rpc-if: Fix HF/OSPI data transfer in Manual ModeGeert Uytterhoeven
HyperFlash devices fail to probe: rpc-if-hyperflash rpc-if-hyperflash: probing of hyperbus device failed In HyperFlash or Octal-SPI Flash mode, the Transfer Data Enable bits (SPIDE) in the Manual Mode Enable Setting Register (SMENR) are derived from half of the transfer size, cfr. the rpcif_bits_set() helper function. However, rpcif_reg_{read,write}() does not take the bus size into account, and does not double all Manual Mode Data Register access sizes when communicating with a HyperFlash or Octal-SPI Flash device. Fix this, and avoid the back-and-forth conversion between transfer size and Transfer Data Enable bits, by explicitly storing the transfer size in struct rpcif, and using that value to determine access size in rpcif_reg_{read,write}(). Enforce that the "high" Manual Mode Read/Write Data Registers (SM[RW]DR1) are only used for 8-byte data accesses. While at it, forbid writing to the Manual Mode Read Data Registers, as they are read-only.

Take this opportunity to update some other minor config options: - CONFIG_MARVELL_PHY moved around because of Kconfig changes. - CONFIG_SENSORS_DRIVETEMP should be selected since is regulates the system critical alert temperature on some devices, which is nice if it is handled even if initramfs or root fails to mount.

2022-04-14ARM: dts: logicpd-som-lv: Fix wrong pinmuxing on OMAP35Adam Ford
The pinout of the OMAP35 and DM37 variants of the SOM-LV are the same, but the macros which define the pinmuxing are different between OMAP3530 and DM3730. The pinmuxing was correct for for the DM3730, but wrong for the OMAP3530. Since the boot loader was correctly pin-muxing the pins, this was not obvious. As the bootloader not guaranteed to pinmux all the pins any more, this causes an issue, so the pinmux needs to be moved from a common file to their respective board files.

2022-04-14ARM: dts: am33xx-l4: Add missing touchscreen clock propertiesMiquel Raynal
When adding support for TI magadc (Magnetic Stripe Reader and ADC), the MFD driver common to the touchscreen and the ADC got updated to ease the insertion of a new DT node for the ADC, with its own compatible, clocks, etc. Commit 235a96e92c16 ("mfd: ti_am335x_tscadc: Don't search the tree for our clock") removed one compatible specific information which was the clock name, because the clock was looked up from scratch in the DT while this hardware block was only fed by a single clock, already defined and properly filled in the DT. Problem is, this change was only validated with an am437x-based board, where the clocks are effectively correctly defined and referenced. But on am33xx, the ADC clock is also correctly defined but is not referenced with a clock phandle as it ought to be. The touchscreen bindings clearly state that the clocks/clock-names properties are mandatory, but they have been forgotten in one DTSI. This was probably not noticed in the first place because of the clock actually existing and the clk_get() call going through all the tree anyway. Add the missing clock phandles in the am33xx touchscreen description. Reported-by: H.

Commit bf781869e5cf ("ARM: dts: at91: add pinctrl-{names, 0} for all gpios") introduces pinctrl phandles for pins used by individual controllers to avoid failures due to commit 2ab73c6d8323 ("gpio: Support GPIO controllers without pin-ranges"). For SPI controllers available on SAMA5D4 and SAMA5D3 some of the pins are defined in SoC specific dtsi on behalf of pinctrl-0. Adding extra pinctrl phandles on board specific dts also on behalf of pinctrl-0 overwrite the pinctrl-0 phandle specified in SoC specific dtsi. Thus add the board specific pinctrl to pinctrl-1.

Flexcom3 is used as board console serial. There are no pull-ups on these lines on the board. This means that if a cable is not connected (that has pull-ups included), stray characters could appear on the console as the floating pins voltage levels are interpreted as incoming characters. To avoid this problem, enable the internal pull-ups on these lines.

2022-04-12ARM: dts: dra7: Fix suspend warning for vpe powerdomainTony Lindgren
We currently are getting the following warning after a system suspend: Powerdomain (vpe_pwrdm) didn't enter target state 0 Looks like this is because the STANDBYMODE bit for SMART_IDLE should not be used. The TRM "Table 12-348. VPE_SYSCONFIG" says that the value for SMART_IDLE is "0x2: Same behavior as bit-field value of 0x1". But if the SMART_IDLE value is used, PM_VPE_PWRSTST LASTPOWERSTATEENTERED bits always show value of 3. Let's fix the issue by dropping SMART_IDLE for vpe. And let's also add the missing the powerdomain for vpe.

On beagleboard revisions A to B4 we need to use gpt12 as the system timer. However, the quirk handling added for gpt12 caused a regression for system suspend for am335x as the PM coprocessor needs the timers idled for suspend. Let's make the gpt12 quirk specific to omap34xx, other SoCs don't need it. Beagleboard revisions C and later no longer need to use the gpt12 related quirk. Then at some point, if we decide to drop support for the old beagleboard revisions A to B4, we can also drop the gpt12 related quirks completely.
