ARM: dts: dra76x: m_can: fix order of clocks

2020-12-02T07:51:54+00:00

[ Upstream commit 05d5de6ba7dbe490dd413b5ca11d0875bd2bc006 ] According to the bosch,m_can.yaml bindings the first clock shall be the "hclk", while the second clock "cclk". This patch fixes the order accordingly.

efi/arm: set HSCTLR Thumb2 bit correctly for HVC calls from HYP

2020-11-24T12:39:06+00:00

[ Upstream commit fbc81ec5b85d43a4b22e49ec0e643fa7dec2ea40 ] Commit db227c19e68db353 ("ARM: 8985/1: efi/decompressor: deal with HYP mode boot gracefully") updated the EFI entry code to permit firmware to invoke the EFI stub loader in HYP mode, with the MMU either enabled or disabled, neither of which is permitted by the EFI spec, but which does happen in the field. In the MMU on case, we remain in HYP mode as configured by the firmware, and rely on the fact that any HVC instruction issued in this mode will be dispatched via the SVC slot in the HYP vector table. However, this slot will point to a Thumb2 symbol if the kernel is built in Thumb2 mode, and so we have to configure HSCTLR to ensure that the exception handlers are invoked in Thumb2 mode as well.

ARM: dts: imx50-evk: Fix the chip select 1 IOMUX

2020-11-24T12:38:58+00:00

[ Upstream commit 33d0d843872c5ddbe28457a92fc6f2487315fb9f ] The SPI chip selects are represented as: cs-gpios = <&gpio4 11 GPIO_ACTIVE_LOW>, <&gpio4 13 GPIO_ACTIVE_LOW>; , which means that they are used in GPIO function instead of native SPI mode. Fix the IOMUX for the chip select 1 to use GPIO4_13 instead of the native CSPI_SSI function.

Update the connection in the DT. Since the IRQ line 0 is used for PMIC as well and cannot be shared with the button, make the button polled.

ARM: dts: imx6q-prti6q: fix PHY address

2020-11-24T12:38:57+00:00

[ Upstream commit e402599e5e5e0b2758d7766fd9f6d7953d4ccd85 ] Due to bug in the bootloader, the PHY has floating address and may randomly change on each PHY reset. To avoid it, the updated bootloader with the following patch[0] should be used: | ARM: protonic: disable on-die termination to fix PHY bootstrapping | | If on-die termination is enabled, the RXC pin of iMX6 will be pulled | high. Since we already have an 10K pull-down on board, the RXC level on | PHY reset will be ~800mV, which is mostly interpreted as 1. On some | reboots we get 0 instead and kernel can't detect the PHY properly. | | Since the default 0x020e07ac value is 0, it is sufficient to remove this | entry from the affected imxcfg files. | | Since we get stable 0 on pin PHYADDR[2], the PHY address is changed from | 4 to 0. With latest bootloader update, the PHY address will be fixed to "0".

ARM: dts: vf610-zii-dev-rev-b: Fix MDIO over clocking

2020-11-24T12:38:57+00:00

[ Upstream commit f8b5a33707c9a19ec905d2826be0acd151997a09 ] The ZII devel B board has two generations of Marvell Switches. The mv88e6352 supports an MDIO clock of 12MHz. However the older 88e6185 does not like 12MHz, and often fails to probe. Reduce the clock speed to 5MHz, which seems to work reliably.
