2021-03-19ARM: dts: apalis/colibri-imx6: standby pmic on powerofftoradex_4.14-2.3.x-imxOleksandr Suvorov
There is a new property to work around the bug of PMIC PF0100. This property turns the pmic into the standby mode on power down the system, that leads to turn off all power rails. In this mode the power consumption is around 2 mA. Related-to: ELB-3580 Signed-off-by: Oleksandr Suvorov <oleksandr.suvorov@toradex.com> (cherry-picked from commit 36c91bbb3ff44beccc48a6e833d2b61e89affeb5)
2021-03-19ARM: imx6: fix setting up pm_power_off callbackOleksandr Suvorov
It is not necessarily that the system with set up the POWER_RESET_GPIO config option has the enabled device "gpio-poweroff". Without this device the "pm_power_off" callback remains uninitialized and the syscall "reboot" converts the signal LINUX_REBOOT_CMD_POWER_OFF into LINUX_REBOOT_CMD_HALT. This leads to skip calling the callback "pm_power_off_prepare" that should do an important work for iMX6+PF0100 systems: it should turns down all power rails of PMIC PF0100 to emulate a "power off" state as a workaround for a PMIC PF0100 with PMIC_ON_REQ and VCC_BATT is supplied from a battery, leading to unable to restart the module either by RESET or power cycle. Note, that gpio-poweroff device still can grab the pm_power_off callback using the property "force-mode" introduced in the commit: 964f69e00a4d ("power: reset: gpio-poweroff: add force-mode") Enable setting pm_power_off callback on the system with POWER_RESET_GPIO config option.

2020-05-07ARM: dts: imx7-colibri: add gpio-line-namesStefan Agner
Add Colibri SODIMM numbers as GPIO line names on module level. The GPIO lines with a name are all available on the SODIMM edge connector of the Colibri iMX7 module and therefore a customer might use it as a GPIO. The Toradex Evaluation Board has the SODIMM numbers printed on the silk- screen. This allows a customer to quickly control a GPIO on a pin-header by using the name printed next to it. Putting the GPIO line name on module level makes sure that a customer gets a reasonable default. If more meaningful names are available on a custom carrier board, the user can overwrite the line names in a carrier board level device tree. The eMMC based modules share all GPIO names except two GPIOs on bank 6 which are not available on the raw NAND devices. Hence overwrite GPIO line names of bank 6 in the eMMC specific device tree file.

Commit 833f2cbf7091 ("ARM: dts: imx6: change the core clock of spdif") changed many more clocks than only the SPDIF core clock as stated in the commit message. The MLB clock has been added and this causes SPDIF regression as reported by Xavi Drudis Ferran and also in this forum post: https://forum.digikey.com/thread/34240 The MX6Q Reference Manual does not mention that MLB is a clock related to SPDIF, so change it back to a dummy clock to restore SPDIF functionality.

2020-03-09ARM: mach-imx6q: add ksz9131rn_phy_fixupPhilippe Schenker
The MAC of the i.MX6 SoC is compliant with RGMII v1.3. The KSZ9131 PHY is like KSZ9031 adhering to RGMII v2.0 specification. This means the MAC should provide a delay to the TXC line. Because the i.MX6 MAC does not provide this delay this has to be done in the PHY. This patch adds by default ~1.4ns delay to the TXC line. This should be good for all boards that have all RGMII signals routed with the same length. The KSZ9131 has relatively high tolerances on skew registers from MMD 2.4 to MMD 2.8. Therefore the new DLL-based delay of 2ns is used and then as little as possibly subtracted from that so we get more accurate delay. This is actually needed because the i.MX6 SoC has an asyn skew on TXC from -100ps to 900ps. Related-to: ELB-1299 Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>
