There is a fix for boot time hangs that can happen on some am335x devices that started when the pruss devicetree nodes were added. The other fixes are less critical: - Fix compiler warning for sysc_init_soc() that got recently introduced - Fix external abort for am335x pruss as otherwise some am335x will hang - Use CLKDM_NOAUTO quirk also for dra7 dcan1 - Fix older NAND device node regression for omap3-sdp * tag 'omap-for-v5.15/fixes-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: omap3430-sdp: Fix NAND device node bus: ti-sysc: Use CLKDM_NOAUTO for dra7 dcan1 for errata i893 soc: ti: omap-prm: Fix external abort for am335x pruss bus: ti-sysc: Add break in switch statement in sysc_init_soc() Link: https://lore.kernel.org/r/pull-1633609552-789682@atomide.com Signed-off-by:

Only one single SCMI Virtio device is currently supported by this driver and it is referenced using a static global variable which is initialized once for all during probing and nullified at virtio device removal. Add proper SMP barriers to protect accesses to such device reference to ensure that the initialzation state of such device is correctly observed by all PEs at any time. Return -EBUSY, instead of -EINVAL, and a descriptive error message if more than one SCMI Virtio device is ever found and probed.

With commit c709135e ("pinctrl: at91-pio4: add support for slew-rate") and commit cbde6c82 ("pinctrl: at91-pio4: Fix slew rate disablement") the slew-rate is enabled by default for each configured pin. The datasheet specifies at chapter "Output Driver AC Characteristics" that HSIO drivers (use in SDMMCx and QSPI0 peripherals), don't have a slewrate setting but are rather calibrated against an external 1% resistor mounted on the SDMMCx_CAL or QSPI0_CAL pins. Depending on the target signal frequency and the external load, it is possible to adjust their target output impedance. Thus set slew-rate = <0> for SDMMC (QSPI is not enabled at the moment in device tree). Fixes: 7540629e ("ARM: dts: at91: add sama7g5 SoC DT and sama7g5-ek") Signed-off-by:

In suspend/resume procedure for AT91 architecture different controllers (PMC, SHDWC, RAM, RAM PHY, SFRBU) are accessed to do the proper settings for power saving. Commit f0bbf179 ("ARM: at91: pm: add self-refresh support for sama7g5") introduced the access to RAMC PHY controller for SAMA7G5. The access to this controller is done after RAMC ports are closed, thus any TLB walk necessary for RAMC PHY virtual address will fail. In the development branch this was not encountered. However, on current kernel the issue is reproducible. To solve the issue the previous mechanism of pre-loading the TLB with the RAMC PHY virtual address has been used. However, only the addition of this new pre-load breaks the functionality for ARMv5 based devices (SAM9X60). This behavior has been encountered previously while debugging this code and using the same mechanism for pre-loading address for different controllers (e.g. pin controller, the assumption being that other requested translations are replaced from TLB). To solve this new issue the TLB flush + the extension of pre-loading the rest of controllers to TLB (e.g. PMC, RAMC) has been added. The rest of the controllers should have been pre-loaded previously, anyway.

SAMA7G5-EK board has DDR3L type of memory soldered. This needs 1.35V. The 1.35V for DDR3L rail at run-time is selected by the proper configuration on SELV2 pin (for 1.35V it needs to be in high-z state). When suspended the MCP16502 PMIC soldered on SAMA7G5-EK will use different sets of configuration registers to provide proper voltages on its rail. Run-time configuration registers could be configured differently than suspend configuration register for MCP16502 (VSEL2 affects only run-time configuration). In suspend states the DDR3L memory soldered on SAMA7G5-EK switches to self-refresh. Even on self-refresh it needs to be powered by a 1.35V rail. Thus, make sure the PMIC is configured properly when system is suspended. Fixes: 7540629e (ARM: dts: at91: add sama7g5 SoC DT and sama7g5-ek") Signed-off-by:

Before commit 0e30f472 ("mtd: spi-nor: add support for DTR protocol"), for all PP command, it only support 1-1-1 mode, no matter the tx setting in dts. But after the upper commit, the logic change. It will choose the best mode(fastest mode) which flash device and spi-nor host controller both support. Though the spi-nor device on imx6sx-sdb/imx6ul(l/z)-14x14-evk board do not support PP-1-4-4/PP-1-1-4, but if tx is 4 in dts file, it will also impact the read mode selection. For the spi-nor device on the upper mentioned boards, they support read 1-4-4 mode and read 1-1-4 mode according to the device internal sfdp register. But qspi host controller do not support read 1-4-4 mode. so need to set the tx to 1, let the common code finally select read 1-1-4 mode, PP-1-1-1 mode. Signed-off-by:

Starting with v5.15-rc1, we may now see some am335x beaglebone black device produce the following error on pruss probe: Unhandled fault: external abort on non-linefetch (0x1008) at 0xe0326000 This has started with the enabling of pruss for am335x in the dts files. Turns out the is caused by the PRM reset handling not waiting for the reset bit to clear. To fix the issue, let's always wait for the reset bit to clear, even if there is a separate reset status register. We attempted to fix a similar issue for dra7 iva with a udelay() in commit effe89e4 ("soc: ti: omap-prm: Fix occasional abort on reset deassert for dra7 iva"). There is no longer a need for the udelay() for dra7 iva reset either with the check added for reset bit clearing.

Commit 078fb7aa ("arm: dts: vexpress: Fix addressing issues with 'motherboard-bus' nodes") broke booting on a couple of 32-bit VExpress boards. The problem is #address-cells size changed, but interrupt-map was not updated. This results in the timer interrupt (and all the other motherboard interrupts) not getting mapped. As the 'interrupt-map' properties are all just duplicates across boards, just move them into vexpress-v2m.dtsi and vexpress-v2m-rs1.dtsi. Strictly speaking, 'interrupt-map' is dependent on the parent interrupt controller, but it's not likely we'll ever have a different parent than GICv2 on these old platforms. If there was one, 'interrupt-map' can still be overridden.
